Price Elasticity of Demand

Suppose the demand for corn increases (due to its use as an alternative energy source), the price of substitutes (such as soybean) decreases. Increase in demand induces a parallel increase in price due to constant constraints in supply. If, for example, there is both an increase in the supply and demand of corn, then market price moves to the initial market price, ceteris paribus. An increase in the demand for a good induces a parallel decrease in the demand for substitute goods, vice-versa. The same case can be said of price. An increase in the price of a good leads to a decrease in the price of substitute goods. Now, if there is an induced increase in the demand for corn, the supply of substitute goods naturally decreases (the increase in the demand for corn induces an increase in its price), as producers shift from the productionprovision of say, soybean, to corn.

Suppose there is a complementary good, say, corn oil. An increase in the demand for corn induces increased demand for corn oil, vice-versa. An increase in the price of corn leads to an increase in the price for corn oil. Any change in either the price or demand of a good naturally leads to a parallel (same direction) change in either the price or demand of complements.

Now, what is the nature of the demand function The demand function is downward sloping (negative slope), showing the inverse relationship between quantity demanded (dependent variable) and price (independent variable). Along the demand function, there are points of elasticity. Suppose the percentage change in price is greater than the percentage change in quantity demanded, the price elasticity for the good (upper portion of the demand function) is inelastic. When the percentage changes for both the price and quantity demanded are equal, the good is said to be unit elastic. When the percentage change in price is less than the percentage change in quantity demanded, the good is elastic. Now, if the good is inelastic (say corn oil), suppliersproducers can actually command higher revenues, because an increase in the price of a good, say corn oil, will have little effect on the quantity demanded.

Elasticity

Quantity demanded of a commodity changes with a change in price. According to the law of demand, quantity demanded increases with a fall in price and declines with a price rise. Producers of goods and services the world over, seeking ways to increase revenues, face a trade-off between increase (or decrease) in price versus fall (or rise) in demand. Whether an increase in price will yield higher revenues despite fall in quantity demanded is the question that permeates their thoughts. The answer to this question is obtained by examining the elasticity of a product. It measures responsiveness of change in percentage of one variable, called the dependent variable, with respect to a percentage change in another variable, known as the independent variable. Total revenue is equal to price of one unit times units sold. When a change in demand is less than the change in price, a price hike may succeed in increasing revenues. Conversely, if demand falls drastically in comparison to price, producers may incur revenue losses on price hikes.
   
Elasticity of demand and supply are widely used concepts in economics. Further, demand elasticity can be divided into three categories, namely, price, income and cross elasticity of demand. Price elasticity of demand measures responsiveness of quantity demanded of a commodity to a 1 percent change in its price. Commonly represented by eD, price elasticity of demand is calculated as percentage change in quantity demanded   percentage change in price. Since the law of demand, states that prices and demand move in opposite directions, eD is always a negative quantity. Elasticity is different from a lines slope as it measures percentage changes while the latter measures simply changes along vertical and horizontal access. Arc elasticity is one way to measure a commoditys elasticity and uses the average values of each of the dependent and independent variables. It gives the average value of elasticity over a range of percentage change. For more accurate estimations, small percentage changes should be used. Movement along a linear demand curve reveals that absolute value of eD is different for different pairs of points on the demand curve and decreases with low prices and high quantities demanded. If the absolute value of eD is greater than 1 for a commodity, it is said to have price elastic demand. When eD  0, the good has perfectly inelastic demand. If the absolute value of eD is less than 1 for a commodity, it is said to have price inelastic demand. When eD  , the good has perfectly elastic demand. Finally, if eD  1, then the commodity has unit elastic demand. A price hike increases total revenue for a price inelastic good while a price decrease lowers total revenues. In case of elastic demand, a price increase lowers revenues while a price decrease increases them. Total revenues remain unaltered for change in price of unit elastic commodities. A single linear demand curve may have both elastic and inelastic regions. Non-liner curves, on the other hand, have constant eD along the curve. Price elasticity of demand is influenced by the availability of close substitutes, household importance and time. Greater the number of close substitutes available and time to respond to price change and less the importance of a commodity in household budget, higher will be the absolute value of eD. A second type of demand elasticity is income elasticity of demand, denoted by eY. It is the ratio of change in percentage of quantity demanded to a percentage change in income, ceteris paribus. Income elasticity may be positive or negative. Rise in income increases the quantities demanded of normal goods and lowers the demand for inferior goods and services. Cross elasticity of demand is the final type of demand elasticity. It measures responsiveness of quantity demanded of a commodity x relative to a percentage change in the price of commodity z. Cross elasticity of demand is positive for substitutes, negative for complements and zero for unrelated goods.
   
Elasticity can also be measured from the supply side. Price elasticity of supply is the responsiveness of quantity supplied of a good or service to a one percent change in it price. According to the law of supply, supply and price move in the same direction. Consequently, price elasticity of supply, denoted by eS, is generally positive. A commodity has elastic, inelastic or unit elastic supply depending on whether eS  1, eS  1 or eS  1, respectively. Supply elasticity increases with increase in time available to suppliers to respond to a price change. Price elasticity of supply, when applied to labor, shows the effect of wage increases on the quantity of supplied labor. In some cases, labor input for people in high paying jobs declines as they devote more time to leisure activities, giving a negatively sloping labor supply curve.

Three developing countries

The three developing countries which have been selected for this particular assignment are Pakistan, South Africa and Czech Republic. The variables which are selected for this cause includes the Population (millions), GDP (billions) ,GDP Per Capita ,Unemployment Rate ,Inflation Rate and FDI Inflow (millions).
Following is a chart that presents the macroeconomic information of the abovementioned variables.

The liberty to conduct a business is relatively well protected in Pakistan under the regulatory environment. It takes almost 24 days to start a business as compared to the 38 days of the world average. The cost related to licensing a business is comparatively high (The Heritage Foundation, 2009).

Czech Republic Financial Freedom
 The financial sector of Czech Republic is one of the most advanced setup in Europe. Restrictions on foreign banks are very low and major insurance companies are very competitive which helps in developing the financial sector of the country (The Heritage Foundation, 2009).    

South Africa Tourism
Tourism is South Africas most important tool of generating revenues. Tourists from different parts of the world come to South Africa to plan their trip and a major reason for selecting this region is because of its affordability natural beauty and adventure (The Heritage Foundation, 2009).

Key features in ranking index
The key features in ranking index include business freedom, investment freedom and trade freedom.

Business freedom
The methodology that is used to calculate business freedom is a quantitative measure. This indicator takes into account the ability to start a business, operate a business and close a business. It also shows the efficiency of a government towards the regulation of these business processes. The factors on which the ranking is based on includes starting a business in terms of procedures, time, cost, minimum capital, operating a license, number of days to obtain license and finally closing a business. All these factors are kept in mind while preparing a score for that particular country. The score lies between 0-100 where 0 represents the minimum amount of business freedom and 100 represents the most convincing business environment. Each of these factors is considered before providing a final score. All these factors are computed individually after which an average is taken which represents that countrys freedom in business (Doing Business, 2009).  

Investment freedom
This factor inspects the policy that particular country has towards the free flow of investment. The investment includes both the foreign investment FDIs as well as the countrys internal capital flow. The investment freedom factor shows impact that investment has over that countrys economics. The things that are examined very closely are the countrys investment laws and procedures, the governments interest towards foreign investments, treatment towards the investors, access to foreign exchange, equitable treatment with the foreign investment against the domestic investors etc.  The criterion which is used in this regard also ranges between 0-100 where 100 is the highest point in which the host country treats the foreign investment same as domestic investment and no restrictions are implied over the foreign investor.  Similarly the ranking goes down with restrictions getting more intense.

Trade freedom
This function of the economy deals with the factors which affects the imports and exports of goods and services. The two information on which the trade freedom is based on are the trade weighted average tariff rate and the non tariff barrier.

GDP Per Capita
This is one variable which is very important in considering the countrys economy as a whole. The GDP per capita is the value of all the final goods and services produced in a country divided by the average population of that country (CIA, 2009).

This would give us the contribution every individual has made in that economy.   We can also say that the GDP per capita is the GDP per person it includes the personal consumption, exports, spending, investments etc (Snippets).

Among the three countries that we have selected for our analysis Czech Republic has the highest GDP per capita which is US 23,700. After Czech Republic comes South Africa with the GDP per capital totaling US 9,500 and last but not the least is Pakistan with a GDP per capita income of US 2,400. The reason why GDP per capita is the most important indicator is because it shows every individuals input in the economy (Snippets).  

Pakistan
The above gives a comparison of these three countries as far as their economic condition is concerned. Among the three Pakistan is the largest country as far as population is concerned the internal political disputes low level of foreign investment and a decline in the exports of the country has been a major factor of Pakistans economic turndown. Quickly changing government regimes has also affected the countrys overall economic condition.

High inflation, budget deficit and lack of foreign reserves have also hurt Pakistans economy. But the biggest factor which is affecting Pakistans economy is the war on terror. Currently Pakistan is in a war zone with its army in direct combat with the militants in the western part of the country. The war on terror has caused big to the Pakistans economy and it has not helped their cause. The foreign investment has also not presented and rightly so in this situation of high uncertainty no one is interested in investment programs.

South Africa
South Africa is another emerging market with abundant natural resources. Mostly its famous for its tourism and tourist from all around the world comes to visit this country every year. The FDI figure in the chart above which shows a negative figure indicated that there is a negative cash flow means that people and corporations are not much interested in investing in South Africa. Also their exports have not been that much good which also has affect on its FDI.

Czech Republic
In Czech Republic the private sector accounts for more than85 of the GDP but besides that as well Czech Republics Eastern Europes most stable economy. This can also be seen from the GDP per capita income and the inflation rate in Czech Republic. Comparatively it has a much stable economy but the factors which are behind this stability are different from what the other two countries are facing.

Millennium Development Goals (MDGs)
In the MDGs Pakistan aces three challenges number one is the disparities in the social sector, number two is the rising inflation and the third is the growing deficit. Czech Republic is in pursuit of meeting its target of eradicating poverty and South Africa is eager to improve its social services as their primary objective of the millennium (MDG, 2007).    

Economic Development and Inflation in the United States

The United States of America has been the central stage of economic activities in the world for more than a century, backed by an abundance of natural resources and entrepreneurial spirit among its citizen making it possible for the country to offer the best wage rates, thereby attracting millions of immigrants from across the globe. Today, the United States Gross Domestic Product is worth 14204 billion dollars which constitutes 22.91 of the world economy (World Bank GDP report 2009).

However, all this would not have been possible but for a very sound political and legal support system that has always been on its toes to regulate the key economic indicators and to keep them at an optimal level. Economic development is not an easy task as it comes with its own sets of woes and complexities to handle. For instance, a direct fall out of an economic growth is inflation, which if not managed properly can do more harm than good for its citizens.

And the United States is no exception to this rule. For instance, the months from June to August 2008, which were characterised by positive growth rates in GDP also witnessed an average inflation of 5.323 (Bureau of Labour Statistics, 2008). All this found the regulators witnessing tough times handling inflation amidst the booming economy.

This research proposes to study the relationship between the economic growth and inflation rates in the United States during the span of 1986-2009 using the panel data regression analysis. The project begins with theoretical discussions on the relationship between the economic growth and inflation. This is followed by a statistical analysis of the historical data of economic growth (measured in terms of GDP growth) and inflation (measured in terms of changes in the consumer price index with 1982 bases of 100) by using E-Views software to calculate the coefficient of correlation using regression analysis to arrive at our conclusion based on the statistical relationship between these two variables.

LITRATURE REVIEW
The relationship between the economic development and inflation is a subject matter of considerable debate among economist. While a certain number of economists emphasize the need for inducement to save and invest if an economy needs to grow, another section lays more importance on consumption. As a direct fallout of this difference, some economists feel that the monetary growth critically determines the inflation while others feel that inflation, which acts as an incentive for the producers to produce more primarily defines the extent of economic growth.

While several empirical studies have been conducted to study the issue using econometric analysis, economists have not been able to arrive at any concurrent conclusion. The reason for the differences in opinions stems from the fact that both inflation and growth rate are interdependent.

Based on these observations, two sets of economic models have evolved, namely, the  growth led inflation and the inflation led growth.

Growth led inflation
The growth led inflation is held to be a healthy signal for an economy. It is a common observation that any economic growth is characterised by the increase in the demand which is immediately followed by inflation.

While inflation generally boosts the production, it also brings along negative externalities like the reduction in the export competitiveness (as international prices may not have risen by the same degree as the domestic prices), the tendency to hoard (to sell at higher prices later) and the lowering of investments (if inflation is combined with severe price volatilities causing uncertain investment environment) on the economy.

The US economy with one of the worlds highest level of consumer spending is, perhaps, the best examples to demonstrate these negative externalities. Consumer spending as a percentage of the economic activity stood at 29 in 1929, grew to 83, dropped to 50 during world war periods but since then has remained in the 70-85 levels. Even during the recession hit 2008 when the consumers were supposedly saving than spending, the consumer spending stood at 72 percent in the U.S. (Mehra, Yash P., and Elliot W. Martin 2009).

Inflation led growth
Given the negative aspects of inflation, most of the economist while agreeing that inflation affects the growth rates of a country, agree that it is not a wise idea to artificially increase inflation to boost economic growth. In the past some developing or underdeveloped countries have experimented with inflation to boost a declining economy. There is enough empirical evidence in this world to show that such attempts have spelled disaster for an economy in the long run.

Nevertheless to analyse the affect of inflation on economic growth in the context of the United States, a regression analysis with inflation as the independent variable (Y) and growth as the dependent variable (X) has been conducted elsewhere in the paper.

III. RESERCH OBJECTIVES
Considering that the growth and inflation are interdependent variables with considerable amount of differences in their relationship interplay and wide differences observed in data collected for different countries, this project aims to study the two hypotheses only in the context of the U.S.  economy.

Hypothesis 1 - There is a strong positive correlation between the growth rate (independent variable) and the inflation (dependent variable) in the context of the U.S. economy.

Hypothesis 2 - There is also a direct positive correlation when inflation is taken as the independent variable and the growth is taken as the dependent variable for the U.S. economy.

These hypotheses will be tested using the historical data pertaining to the GDP growth per year and the indicative inflation rate for the US economy from 1986 to 2009. (48 years)

Methodology
For the purpose of this study, the inflation has been measured using the consumer price index (CPI) which is defined as the change in the prices paid by urban consumers for a representative basket of goods and services. The producer price index (PPI) has not been used as CPI is traditionally assumed to give a greater representation of the prevalent prices in the economy as compared to PPI.

Similarly to measure the economic growth we have decided to use the annual GDP growth from amongst large number of economic indicators.

The researchers are aware that the results of such a study may vary widely from country to country. While some country may have a strong positive correlation others may show a negative correlation as well.
These two hypotheses are therefore being tested only to study their interplay in the American context and are not intended to arrive at any judgments about the general relationship between the economic growth and inflation.

Theory Discussions
The aggregate supply-aggregate demand (AS-AD) economic theory suggests a positive correlation between inflation and growth, when viewed from the growth led inflation framework. However   since 1970s several countries experienced stagflation which is characterized by very slow economic growth, but accompanied by inflation. The most recent situation of stagflation was witnessed nowhere else, but in the United States in 2008, when it grew at a meagre 0.43 where as inflation rose to as high as 5.2 in the months of June to August in the country. (The average inflation for the year was 3.85). All these events, thus, negate the AS-AD postulation of a positive correlation between the inflation and the economic growth.

The classical theory which postulates a supply driven economic growth suggest that economic growth of a country is primarily led by savings which are then used for further production than being used in the current consumption. However, even this theory is not able to explain, how the United States with the highest proportion of consumption and almost negligible savings rate was witnessing 10-11 growth in several years during the period of 1970-1985. The personal savings rate in the United States has averaged around 1 since 2000, as compared to the average 13 personal savings rate in Japan, 12 in Germany and 15 in France. (Federal Reserve Bank of San Francisco). If an economy is growing even at 3 with a negligible savings of 1, the classical theory also does not seem to hold good in the situation.

The Keynesian model which studies the interplay between the aggregate demand and the aggregate supply in the short run and a long run time-frames explains the relationship between the economic growth and the inflation including an explanation for the stagflation which is not offered by other economic models.  According to this model, the AS curve is upward sloping in the short run inflation and output exhibit a positive relationship, because in the short run, producers feel that the price rises are happening only for their product. However, as the general price rises, and the manufacturer continues producing more, a time comes in the long run when the production decreases and the inflation rises. This theory, thus, postulates that any level of inflation is sustainable however, for the inflation to fall there must be an intermittent period when the economic growth is below the natural rate. Keynesian model is, therefore, somewhat able to explain the situations of stagflation witnessed in the U.S. economy in the second half of 1998.

The monetarism theory (Friedman, 1960) links inflation to an increase in the supply or the velocity of money. It states that inflation occurs when the velocity of money is greater than the rate of growth in the economy. This theory, however, does not explain the effect of inflation on the economic growth. In short, the monetarism proposes that in the long-run, prices are mainly affected by the growth rate in money, while having no real effect on growth.

EMPIRICAL RESULTS
This part of our research paper is divided into two sections
Regression analysis with GDP growth as the independent variable and inflation as the dependent variable (Growth led inflation model).
Regression analysis with inflation as the independent variable and GDP growth as the dependent variable (Inflation led growth model).

The data used for the regression analysis were taken from two websites providing statistical facts about the U.S.  The hypothesis was then tested against the results of regression analysis.

Regression analysis results with GDP growth as the independent variable and inflation as the dependent variable (Growth led inflation model).

According to the regression results for the growth led inflation model, the results are symmetric to the proposed hypothesis.  The coefficient calculated with inflation as the dependent variable is positive. R2 which is the measure of fit between the regression and the data, appears to be 0.305659 which indicates a reasonable the fit of the values between the dependent and independent variables.

Regression analysis with inflation as the independent variable and GDP growth as the dependent variable (Inflation led growth model)

According to the regression results for the inflation led growth model, the results are again symmetric to the proposed hypothesis.  The coefficient calculated with GDP as the dependent variable is also positive.

Conclusion
This simple panel regression exercise reconfirms a significant degree of correlation between the inflation and the growth rates in general and a positive correlation between these two variables in the United States.
While no hard and fast conclusions can be drawn out from this analysis, we can always look at the results derived from this and similar exercises to help economists and decision makers identify the best ways of using inflation to drive economic growth and to understand what aspects of such an analysis inhibits the economic growth.

Concerning how much inflation is the best for the economic growth of the United States - some economists
suggest that with such a high level of consumer spending, a 2.5-3.5 GDP growth per year is the most that the U.S. economy can safelymaintain without causing negative side effects. (Ryan Barnes 1).

Possible implications for policy and practice

VI. Comparison with other empirical research

Several other researches, conducted on the same topic, but concerning different countries and situations, have pointed to and confirmed the results obtained in our regression test.

The results of this study have been compared to the working paper on the same topic for the Island of Fiji and both these results seem to point to a high degree of positive correlation between inflation and economic growth.

A NBER working paper titled Inflation and Growth, 1986 also points to a high degree of positive correlation between inflation and growth rates in various econmies.

While in some cases of the stagflation trend in the economy, negative correlation has been observed, in general all the papers that we came across on the subject confirmed of positive correlation between these two variables when the study covered more than 10 years of historical data.

Britains Economic Structure

Britain is now the 6th biggest economy of the world based on the GDP figures. Its active development began with the industrial revolution of the 18th century when the economy of Britain moved from manual labor to mechanization. There were major shifts in different sectors of the economy mainly in fishing and farming, mining, manufacturing and even transport. Britain started to change its focus from the Primary sector towards the Secondary sector. As the market revolution and the mechanization continued Britain was able to become one of the most powerful economies in the world. The needed raw materials for this expansion came from the different British colonies that existed at that time. However, as standards of living rose and the demand for services was established, during the 1970s people saw a shift from manufacturing towards the tertiary sector. It was during this time that the services sector really picked up as the required training and skills were made available. Currently, around 80 of the UKs GDP consists of the tertiary sector products. However, this move to the services sector has seen a lot of criticism by different economists and politicians who think that the manufacturing sector of the economy has been abandoned and that the government has ignored this fact. They agree that the market revolution eventually leads to the 3rd stage, but believe it is not the revolution that caused this, but the policies of the government. In the following discussion viewpoints of both sides are presented and a conclusion, summarizing them is made.

The manufacturing sector is considered important, because it employs the majority of the population. The different industrial units engage the lower and middle class labor which forms a major part of the workforce. The skills that these people have acquired throughout the years have made them efficient and productive in their respective industries. Their economic prosperity is directly linked to the growth of the secondary sector. They depend on it, because they do not have the formal education that is needed today to get employed in the services industry. Thus taking this argument into consideration, many economists consider it mandatory that the manufacturing sector should grow so that the major chunk of the labor force is not unemployed. However, it happened that during the 1980s the when the rates of the growth in the British economy were high the increase of production levels in the manufacturing sector was only 0.5. What followed was a continuous wave of unemployment over the years.

The exchange rate mechanism era, as it is called, started during the early 90s and it adversely affected the manufacturing sector. The high interest rates prevailing at that time raised the cost of capital for local manufactures, whereas their foreign competitors were paying lower rates. Thus, the average costs of production for the British manufacturers were much higher and this made them uncompetitive. Also, the exchange rate management during the era hurt the export potential of local businesses. An overvalued Pound Sterling made British exports appear expensive in the foreign markets and a major source of earnings was lost.

It is true that the limited growth of the manufacturing sector may, in part, be attributed to the market evolution. Some economists consider de-industrialization to be a stage in the economic development process. They say that just as the industry moved from the agriculture to the manufacturing sector during the industrial revolution, this too is simply another move from the secondary sector towards the services sector. However, others claim that the pace at which de-industrialization has occurred in Britain has been too rapid to be attributed to the revolution. There is considerable debate going on over the issue, what is required is more concrete and valid information on the subject.

Sometimes it is difficult to classify something as being primarily tertiary or secondary. As in the case of McDonalds, it is a part of both sectors since it is delivering valuable intangible services to the customer and is making tangible food items for consumption. So in some cases the dividing line between the two opposing sectors is thin and the ongoing debate does not apply to these sectors. But, such examples are rare and there are services that may be classified as one or the other. These from a major part of the economy and hence are the focus of the essay. For manufacturing firms too use services when they market their product, prepare the budget and have inventory checks.

Mr. Peter Lawrence, the Chairman of the Associated British Industries has identified an important trend in the British economy. He points out that manufacturing businesses used to employ night watchmen, laborers, cleaners and maintenance workers but this is no more the case. Todays manufacturers outsource cleaning services to specialized firms, the lease on full maintenance trucks and cars, and hire labor on a contract basis now. All this has resulted in a decrease in the number of people employed in the manufacturing. It has also led to a reduction in the value added by the sector. It seems that the manufacturing sector is shrinking while the Services Sector grows. New practices such as outsourcing have led to a gradual decline in the industrial base in the UK.

According to Professor David baker, a business economist at the University of Birmingham, de-industrialization is a phenomenon that is currently prevalent in the British economy. He believes that as the situation develops, the manufacturing sector will keep on losing its share in GDP. He describes a process where the smaller firms will go out of business first and then eventually the bigger players in the industry will follow. He believes that the British economy is now in the state of de-industrialization. However, Britain is not the only one experiencing this state. The United States and other major economic powers of the world are in a similar situation. So why are some elements in the British economy worried about it Because what Britain is experiencing is called negative de-industrialization, which is a state where the sectoral pattern of employment is changing just like in positive de industrialization, but as opposed to positive, negative deindustrialization leads to a low growth in output and even lower growth in rate of growth of productivity.

Some believe that de-industrialization is just an inevitable stage in the process of development but not Mr. John Wells. An Economist at Cambridge, he believes that de-industrialization can be prevented. He claims that the underlying assumption behind the whole concept of de-industrialization is that as living standards rise, the consumers demand becomes more sophisticated. They now start demanding more of the tertiary goods and so the economy comes to the final stage of the growth process where the market starts supplying the required services that the consumer demands. The rising demand for services means that consumers are moving away from manufactured goods and, hence, aggregate the demand for manufactured goods is decreasing. However, the condition in Britain is opposite. Statistical data show that the demand for manufactured goods has been rising in Britain instead of falling as suggested by the normal situation of economic progress. Mr. Wells points out that the data supports the view that the aggregate demand for manufactured goods has been rising at approximately the same rate as tertiary goods. The anomaly actually was that as demand for manufacturing and the tertiary rose, the tertiary output was increased to a level to fulfill that demand, but manufacturing output didnt rise enough compared to the demand. So those who are of the view that consumption patterns are switching away from the manufactured to the tertiary goods are mistaken. The real problem is that the British manufacturing units are not efficient enough to compete at the international level and so are losing market share. The overall decline in Britains share of world trade in manufactures supports this view.

The most crucial factor that has hit many firms in Britain is the cost of wages. Labor costs are very high in the UK due to the higher standards of living and higher minimum wages prevailing in the country. Compared to Britain, developing countries, like of India, China and Brazil, have very low labor costs, since the population levels there are high, workers are not trained, there is massive unemployment and the minimum wages are very low. So these developing countries are considered to be more suitable for manufacturing labor intensive products, hence, many western firms have moved to these developing countries looking for better profits. These goods are exported to developed countries, like the UK itself, where they can easily compete with more expensive British products.

Mechanization has also hit the local labor in the UK. Due to the advanced technical machinery available today, many tasks that used to be done by manual labor are done with a machines now. So the local labor that was employed in the manufacturing sector started seeing job cuts. The simple reasons for the change can be many including saving time, costs and increasing efficiency. As machines have made the production process faster, cheaper and easier in many cases, firms have substituted capital for labor. However, labor is still needed to make the machinery work, so labor is not completely out. However, it is a fact that todays labor force is not the same as that in the industrial era, todays labor needs to be highly trained , skilled and efficient and so acquiring such skills has become mandatory for everyone.

Therefore, what if Britain is under this negative de industrialization situation Britain is suffering a lot due to this domestic economic phenomenon. It was pointed out by the House Of Lords Select Committee investigating de industrialization that this situation would lead to major economic problems for the nation. The manufacturing trade balance has been positive over the years, balancing the overall deficit that occurs due to shortcomings in the other sectors. However, since 1982, the share of output in the current account has declined and gone into a deficit and now there is no other element to plug the rising balance of trade deficit. As the deficit on the current account and eventually the balance of trade expands, this can become very harmful in the long run.

The gap left by the decreased manufacturing output just cannot be filled by the services sector. Trade in the services sector is a relatively new phenomenon and countries are trying to get to understand the workings of the system. But because the situation is new, there isnt much regulation with regard to the international trade in services hence, countries are not really trading services at a substantial level. So, with the lack of manufactured output and little trade in the tertiary sector, the balance of payments for Britain may go into a permanent deficit. Countries that have experienced prolonged deficits, countries like Argentina and Ecuador have borrowed heavily from international lenders and have been servicing debts heavily ever since. The rising interest rates have consumed most of the income of these nations and left them with little for investment into infrastructure and development, their standards of living dropped as well. Britain is far from reaching the stage seen by Latin American countries, but if budget deficits persist and the deficit value grows, there is no telling where Britain could end up.

Professor Nicholas Calder, a well known economist pointed out a strange link between the rate of the economic growth and the growth of the manufacturing sector. Caldor pointed out that manufacturing is special to the extent of the benefits that can be derived from the economies of scale and from experience. Only the manufacturing sector can truly take advantage of economies of large scale and division of labor. The services sector, on the other hand, is dependent upon the number of service providers and the amount of service that they will provides. Also, he noticed that productivity growth in the tertiary sector has averaged around half of the growth rates seen in the manufacturing sector. So the smaller the manufacturing sector the less it can avail economies of scale, leading to a slow overall economic growth.

Thus, it is established that de-industrialization is a significant problem that needs to be resolved. One of the correction methods has been of nationalization and public ownership. During the 70s there was a wave of nationalization in the country and the government took control of some production units that were running in losses. However, nationalization only made the situation worse. The firms started seeing even more losses, politics came into the running of the organization and the running of the units became politicized. There was little growth in productivity, output growth declined sharply and overall industrial operation got out of hand. There was also some research and development (RD) by the state but it failed miserably.

Later, some economists like Harriet Harman came with their own conclusions. They noticed that the three things that were required for the manufacturing growth, ones which were absent from the British economy, were RD, investment and skills training. Therefore he proposed that the government provide the private sector with some support in the above three fields. Why should the tax payers money be used in the rescue Firstly, because these companies do not have the required funds for investing in product development and research, or in skill training. This leaves them behind foreign competitors who have invested their profits into skill development and research programs. This sort of package would enable the British manufacturers to move out of their current state of low investment, low profitability, low productivity and get out of this circle of poverty. Secondly, British firms may not be investing back their profits in RD and skill development because of the current government policies of nationalization. The government wants to bring companies under the public sector so that they maybe run in a better way. This has alerted private investors who avoid putting a lot of money in such long term projects because of fear of the government takeover in the future. So, such an insecure environment is disturbing to the growth of the manufacturing sector. Others suggest that instead of taking over firms, the state should have a supportive investment climate and introduce investment incentive programs like tax rebates or accelerated depreciation allowances. This way the trust of the local entrepreneurs can also be won who are now sure that their companies wont be nationalized, and the sector will receive the required boost it needs to improve.

However, the picture of the manufacturing sector is not so gloomy altogether. Considering the cases of industries, such as publishing and printing, aerospace and chemicals. Starting with publishing, the United Kingdom is considered a major publishing centre of the world. The industry in Britain is massive and publishes books for different international clients. Some major publishers, such as Pearson and Palgrave, have moved some of their operations to America and are giving the local competitors there a very tough time and in due course have taken over some of these local competitors.

The British chemical industry has average around a 5 economic growth since the 90s, mostly coming from the pharmaceutical sector. This is due to the rising demand for advanced medicine and over the counter drugs. There are more than 12,000 pharmacies in the drug store market throughout the UK.

The UK has the second biggest aerospace industry in the world by employment terms. The different players in the industry include the Airbus consortium for civil airplanes, and other military purpose programmes are namely Euro fighter typhoon program and the joint strike fighter programmes. Another major player is BAE systems (BAE), a major combat plane manufacturer. In 2003, the contribution of the aerospace industry to the GDP stood at 17 billion pound sterling. This formed around 4 of the total contribution by the manufacturing sector. The exports of the industry stood at around 2.5 billion pounds in 2003. Employment in the industry is around 122,000 (direct) which 0.4 of the total workforce is. Productivity has also been growing in the sector it was 50 higher than the UK average and 40 higher than the manufacturing average. The total investment in RD by the industry stood at around 2 billion pounds. The British aerospace industry holds around 10 of the global market for aerospace.

Some service sector industries that have shown good face and are considered to be the  major players in the British economy include Telecommunication, E-commerce, Retail, Tourism, and, most importantly, financial services. The telecommunication sector is worth 1.7  of GDP and is worth more than 34 billion. The ecommerce market is expanding rapidly today. It is now worth more than 3 billion and there are above 9000 companies involved in e commerce and another 72000 do business over the internet. Franchises are a massive one-third of the British retail sector. There are around 40 major American brands in the UK which employ around 30,000 workers in more than 3000 stores throughout the UK. The total worth of the apparel market is today more than 40 billion.

Conclusion
As has been discussed above the manufacturing sector has seen decline over the past few years in terms of the number of people employed the share in GDP, output growth and the productivity growth. However, there are fields in which the manufacturing sector has picked up such as aerospace and chemicals. As these operations are more capital intensive they require a lower amount of labor. So, the trend here has been moving from the more labor intensive industries such as textile, steel and mining towards more technical ones like telecomm, aerospace and chemicals. However, there is no denying the fact that the manufacturing sector has seen decline in the classic industries such as textiles for which consumer demand is still very high. But in todays global village where international trade is the way forward, the British economy has a comparative advantage in the more technical productions and it should focus on that while trading it for other labor intensive products. The labor that used to be employed in the former sectors will now have to be trained and educated and moved to the capital intensive industries. However, this is easier said than done and requires major policy reforms. The services sector is the way of the future and is the third stage of the economic progress and Britain has developed a very efficient tertiary side especially in financial services. The UK used to be known as the financial hub of the world after New York before the financial crisis got to the world. British finance industries are major players in the global economic scenario and are specializing in the field of financial services. From the perspective of international trade, the tertiary sector is relatively new, but a lot of ground has been covered by these financial intermediaries who have moved their operations to different parts of the world and are running companies from remote locations. All this has been made possible by the massive technological advance made and the future of the financial services industry looks very bright. There are other players in the British services sector too, namely tourism and retail and their future looks bright as well. So I would agree to the fact that the British manufacturing has gone down, but in consequence of that the services has come up too. Manufacturing is now moving toward new industries that are more tech- based and capital intensive, hence, a structural change is required for that. Services are already developing fast and we have an absolute advantage in this sector. The goods that the manufacturing sector used to specialize in are now being produced by the develpoing countires as they now have the suited resources to produce them. Through international trade all goods can be exchanged for the other making everyone better off.

Economics The Study of Choice

Definition Economics is a social science that studies how people choose amongst alternatives available to them, when wants are unlimited compared to the resources.

Ideas Central to Economics 1. ScarcitySince wants are unlimited and the resources to fulfill them are limited, this condition of scarcity forces us to choose among various alternatives. The issue of scarcity raises three most important questions in every economy a) What should be produced b) How should goods and services be produced (Labor intensive or capital intensive, production in own country or foreign country etc). c) For whom should goods and services be produced 2.Choice The problem of choice arises as resource can be put to alternative uses.3.Oppurtunity Cost It is the value of the best next alternative forgone in making the choice.

Difference between Economics and other Social Sciences

1. Emphasis on Opportunity Costs Economic thinking emphasizes on the value of alternatives in each problem involving choice. 2. Individuals maximize in pursuing Self-Interest Economists assume that individuals make choices that maximize value of some objective like firms maximize profit objective and consumers aim at maximizing their level of satisfaction.3. Choices are made at margin Economists argue that individuals pay attention to the consequences of small changes i.e. a little more or little less of the activities they pursue.

Branches of Economics a) Microeconomics is the branch of economics that studies individual decision making i.e. consumers and firms. Issues such as the price determination of a firm, price of the tickets of the concerts etc are part of microeconomics study b) Macroeconomics is the branch of economics that studies the decision-making at the macro level i.e. for the economy as a whole. Issues such as rate of inflation, unemployment rate etc are part of macroeconomics study.

Careers in Economics

1. Majorly economists work in three types of organizations  a) Business firms     b) Government agencies c) Colleges and Universities

2. Other Jobs The undergraduate degree in economics helps to make a career as financial managers, financial analysts, underwriters, actuaries, securities and financial sales workers, credit analysts, loan and budget officers, and urban and regional planners.

Similarities between Economics and Other Social Sciences
Unlike other social sciences, economics also uses scientific method to conduct research.  To study the complex real world, economists use model i.e. set of assumptions about the real world. Hypothesis are suggested and tested (commonly uses ceteris paribus assumption for tests), if true - further tested and become theory after general acceptance. Generally two kinds of assertions are tested. a) Positive statements- statements of facts. b) Normative statements-statement of value judgment.
And finally become law after universal acceptance.

Chapter 2
Confronting Scarcity Choices in Production

Factors of production in the economy help to produce goods and services, which in turn creates utility for the consumers. 1. Labor It is the human effort applied to production. 2. Capital It includes physical goods and intellectual discoveries.3.Natural Resources It is the resources that are found in nature and help in the production process. The knowledge to be applied to the factor of production (technology) and entrepreneur who uses technology with other factor of production play an important role in the production process.

Production Possibility Curve
Definition A production possibility curve is a graphical representation of the alternative combinations of goods and services that an economy can produce with factors of production and technology fixed.
Example Suppose there are three plants of one firm that can produce skis and snowboards. The table below shows the various combinations that plant 1 can produce. The PPC curve is downward sloping reflecting the scarcity of capital and labor (as producing more skis means shifting the resources from snowboards). The slope of the curve measures the opportunity costs forgone in producing more of the good on the horizontal axis for the quantity of the good on the vertical axis forgone.

The slopes of all the three plants differ with lowest opportunity cost at Plant3. Thus if firm decides to produce more snowboards, it will use Plant 3. Economists state that an economy with the lowest opportunity cost of producing the good has comparative advantage over the other economies. But if we combine all the three we get a concave curve reflecting law of increasing opportunity cost (i.e. if we produce more of one good opportunity cost of that good increases). And the more we add the production facilities the smoother the curve becomes.

Movements along the PPC curve Suppose the economy is at Pt. B (producing security and all other goods), and movement along the curve to pt. C requires shifting the resources from good to the other (Fig3).
Movement toward the PPC curve (i.e. from point inside to the point on the PPC) An economy operates inside the PPC when there is underutilization or misallocation of the resources (not allocated on the basis of comparative advantage). The economy does not operate at full employment at pt. B.  When the idle factors of production are utilized fully the production of both goods rises and economy operates at Pt. A(Figure4).

Moreover, factors of production when not allocated according to comparative advantage result in inefficient production (Figure5). Thus the economy flourishes and specializes when operates on the PPC curve.

Application of PPC

1.International trade An efficient world production i.e. resource allocation on comparative advantage allows the economy to operate on the PPC curve. If the nations specialize, they rely on each other and trade. The implications of the PPC model are powerful for international trade as it helps in more production of goods and services and helps in achieving full employment too.

2. Economic Growth An increase in the quantity or quality of factor of production allows more production of goods and services in turn shifts the PPC curve outwards and raises the economic growth. Though we have assumed factor of production and technology to be fixed, but the automated production, innovation in transportation, development of modern information have changed the scenario a lot in real.

3. Choice of Economic System The world economies are somewhere operating between capitalism and socialism i.e. they are mixed economies. The global shift has tilted the world economies towards the capitalist economic system, which provides more of economic freedom and more inducement toward allocation of resources on the basis of comparative advantage. And this also raises the income per person. But governments role, though limited, remains fundamentally important.

Demand And Supply

Demand
Law of Demand The law states, the quantity demanded falls when the price rises, all other things unchanged(Ceteris paribus).

Demand Schedule  Demand Curve It is the table that shows the quantities of a good demanded at different price at a particular period of time. The graphical representation of the demand schedule is the demand curve.
     
 Figure1 Demand Schedule  Demand curve

Determinants of Demand Besides price, there are various variables affecting demand a) Preferences Change in the preference that is popular shifts the demand curve to right and the less popular one shifts the curve to left. b) Prices of related goods and services The fall in the price of the complementary raises the demand while substitutes demand fall with the fall in the price. c) Income Generally, the demand for the good rises with the rise in the income but inferior goods are exception to the rule. d) Demographic Characteristics Greater the population, greater the demand. e) Buyer expectations Future expectations for price rise will shift the demand curve to the right and vice versa.

Movement along the demand curve  Shift of the demand curve The change in demand due to price causes the movement along the demand curve, while changes due to other determinants causes shift (to right or left) of the demand curve.

Supply
Law of supply The law states, An increase in the price results in the increase in the quantity supplied, all other things unchanged.

Supply Schedule  Supply Curve The table showing the quantities supplied at different prices during particular period. And the graphical representation of the schedule depicts the supply curve in the figure below.
 
 Figure2 Supply Schedule  Supply curve

Determinants of Supply Besides price there are other factors that affect the quantity supplied by the sellers a) Prices of factor of production An increase in the factor prices will decrease the quantity supplied and vice versa. b) Returns from the alternative activities An increase in the returns from the alternate activities decreases the supply. c) Technology An improvement in the technology (such as use of computers) increases supply while certain equipments (such as pollution control devices) reduce supply. d) Seller Expectations Future expectations of price rise decreases the current quantity supplied. e) Natural events Storms, droughts etc reduces supply while unusually good harvest increases the supply. f) No. of sellers More the number of sellers greater will be the supply.

Movement along the supply curve and shift of the supply curve This figure below sums the topic clearly

Equilibrium
Determination of the equilibrium The intersection of the demand and the supply curve at a single point determines the equilibrium price and quantity.

Any other price other than the equilibrium price puts the market in disequilibrium. Any surplus will cause the price to fall and ultimately reach the equilibrium price. Similar happens in the case of shortages too.
Movements in Demand and Supply Curves The movements can be individual or simultaneous in both the curves.

Individual shifts
Changes in the curveEffect on equilibrium price Effect on equilibrium quantityIncrease in demandPrice increasesQuantity increasesDecrease in demandPrice decreasesQuantity decreasesIncrease in supplyPrice decreasesQuantity increasesDecrease in supplyPrice increasesQuantity decreases

The simultaneous shifts If the simultaneous shifts in demand and supply cause the equilibrium price and quantity to move in same direction, then price and quantity move in same direction. If the shift in the curves is in the opposite (i.e. one falls and other rises) then shift in price and quantity is critical to find out, depending on the shift. (How far or how close).

The Circular flow Model It provides the insight how markets work and are related to each other. Firms supply goods and services to households, who in turn supply factor of production to firms. The factor payments made by the firms become the income of the household. Thus the whole process is circular and ongoing.

Chapter 5.
Elasticity A Measure of Response

Definition Elasticity is the ratio of the percentage in quantity demanded in a dependent variable to a percentage change in an independent variable.

Price Elasticity of Demand Definition - It is the percentage change in the quantity demanded of a particular good divided by the percentage change in the price of that good or service, all other things unchanged. It reflects the movement along the demand curve and is always negative.

Ways of computing price elasticity a) Percentage Method We compute the percentage changes in both the quantity demanded and the price and divide them to arrive at a value of elasticity. b) Arc Method This method is generally used when we have linear demand curve. It calculates the percentage changes relative to the average value of each variable between two points. It is an approximate method and cannot be applied to large changes. The price elasticity falls as we move down and to the right of the linear demand curve.
Categories of price elasticity a) Price inelastic (a given percentage change in price results in smaller quantity demanded). b) Unit elastic (a given  change in price does not change the quantity demanded). c) Price elastic (a given percentage change in the price leads to bigger change in the quantity demanded).

Impact of elasticity on total revenue As per the law of demand the quantity demanded is inversely related to the price but the total revenue move in the direction of the variable by the larger percentage (and remains same if variable move by the same percentage).

Determinants of price elasticity a) Availability of Substitutes - closer the substitutes available, greater the price elasticity. b) Importance of households - the goods that affect the purchasing power definitely affects the quantity demanded. c) Time - greater the elasticity when more time is allowed to the consumers.
Income Elasticity The percentage change in the quantity demanded at a specific price to the percentage change in income is called income elasticity (denoted as ey). Categories of income elasticity a) Positive income elasticity - Normal good (an increase in income increases demand and vice versa). b) Negative income elasticity Inferior good (increase in income reduces demand and vice versa).

Cross price elasticity of Demand The responsiveness of demand for a good or service to the change in the price of another good or service is called cross price elasticity of demand. Categories of cross elasticity a) Positive cross elasticity Substitutes (an increase in the price of one will lead to the increase in the demand of the other). b) Negative Cross Elasticity-Complements (an increase in the price of will lead to the reduction in the demand for other. c) Zero Elasticity- unrelated (change in the price of one will not affect the demand of the other).

Price Elasticity of Supply The ratio of the percentage change in the quantity supplied to the percentage change in its price is called price elasticity of supply (ceteris paribus).Categories of Supply elasticity a) Perfectly inelastic. b) Unit elastic. c) Perfectly elastic.

Time is an important factor, as more the time more price elastic is the supply curve.

Chapter 6
Markets, Maximizers, and Efficiency

Logic of Maximizing Behavior Economists argue that individuals maximize their objectives. Consumers seek to maximize utility and firms seek to maximize economic profit. In this model, we assume that consumers and firms maximize the net benefit (total benefit minus the opportunity costs) of each activity, with benefits and costs given. And to maximize their respective objectives, they evaluate the additional benefit and additional cost of each activity. So therefore economists apply the marginal decision rule to it. The rule says that If the additional benefit of one more unit exceeds the extra cost, do it if not, do not. But there are constraints to it, as the consumers cannot go beyond their income or budgets and firms not beyond their production capacity. And if an activity is carried out at less or more than efficient level, the loss in net benefits is called the deadweight loss.

Figure Using Marginal Benefit and Marginal Cost Curves to Determine Net Benefit
Maximizing in the Marketplace In 1776, Adam Smith argued that efforts by the individuals to maximize their own objective maximize net benefit for the economy as a whole, as it allocates the resources efficiently.
Conditions for efficient market allocation a) marketplace must be competitive. b) Allocation regarding property rights (property rights must be exclusive and transferable). When the efficiency condition is met the market demand and market supply can be interpreted as the marginal benefit and marginal cost curves.

Producer and Consumer Surplus Both buyers and the sellers want to be better off in a transaction in the marketplace. The benefit of the consumer is measured in terms of consumer surplus (difference between total benefits of consuming and the total expenditures of a given quantity) and that of the producer in terms of producer surplus (difference between total revenue received and the cost of producing a given quantity of output). The sum of consumer surplus and the producer surplus measures net benefit to society of any level of economic activity. Thus the net benefit is maximized when demand and supply curves intersect.
Efficiency and Equity When the condition of efficiency is achieved in a market the condition of equity i.e. equitable distribution of income arises. Governments step in as markets are not fair enough for equitable distribution of income (taxes for rich and welfare programs for poor).

Market Failure When market fails to achieve the efficient allocation of resources (due to failure of the abovementioned conditions) is termed as market failure. a)Non-competitive markets - It is the case where buyers and sellers are powerful to influence the market price. b) Public goods-in, which the cost of exclusion is prohibitive and marginal cost of additional user, is zero. Thus condition of efficient allocation is violated. Therefore the governments step in, and supply by direct provision or buy from private agencies on contract basis. The efficient level is Q but free riders prevent to produce the efficient level and causes deadweight loss shown by triangle ABC. Example national defense.

External costs and Government Intervention If an activity generates external costs the decision maker will not be facing it, so government intervened to achieve the efficiency level (taxes or direct regulation).
Common property Resources In these the property rights are not defined so no efforts are taken to preserve them. So the governments impose limits.
When I entered college in Canada for a four-year program in Economics in 2007, I had my mind set on pursuing a career in economics.  I prepared myself for this by actively participating in several class assignments, particularly the economics courses.  In those and other several projects, I have understood the different dynamics that come with working for a financial firm. This has kept and maintained my thirst for this great profession over the years and as my records indicate, every day has been an opportunity to polish on what I have previously learned in school.  As my records show, I have continuously shown improvement in my academics in my years in college.

Economics, as a field of study, is a very interesting discipline in that it touches on many other subjects.  The relationship between people and society is one that can be partially explained by the main concept of economics as a study on the allocation of scarce resources among a group.  For one thing, an understanding of economics allows one to see how the current economic crisis is affecting people and dampening employment.  Having had an interest in international trade, I feel that I also want to venture more into matters that revolve around international monies and trade, not leaving behind environmental economics and natural resources.  In my further studies, I look forward to getting more insight regarding foreign exchange in different regions of the world as well as models used by different federal governments to address budget surpluses and deficits in their jurisdiction.

My concern does not end there.  I am interested in learning how federal spending as well as income is handled.  Further, I would like to understand mode and dynamics of taxation both to individuals and organizations.  Under the field of environmental economics, taking it as a minor, I would like to get a better understanding of the actual resultant of pollution, natural calamities such as global warming and recent tsunamis, among others.  Of great importance is the link between the economic costs and benefits versus implementation of environmentally friendly laws.  I strongly believe that economic development should not occur without properly examining the impact that is has on the environment.

There are many who feel that education ends upon completion of college.  I feel differently, however, and understand that there is so much that can be learned in further studies such as graduate school.  In line with my decision to pursue my studies in graduate school, I understand that there are more opportunities for those who receive the extra training necessary to be ahead in todays competitive world.  I feel that in order for me to gain an advantage in the field of economics, I need to devote more time and energy in learning more about the recent developments in this field.  This will enable to pursue my career as a financial consultant or an economist in the future.  As such, I formally present my intention to apply for this course at your prestigious academic institution.
