Real Gross Domestic Product (GDP) during the first quarter (January through March) of 2002 increased at an annual rate of 5.8 percent. This is the advance estimate for the first quarter and will be revised in the preliminary and final estimates over the next 2 months. During 2001, real GDP changed at annual rates of +1.3 percent, +0.3 percent, -1.3 percent and +1.7 percent for each quarter respectively. This is the fastest rate of growth of GDP since the fourth quarter of 1999. The growth rate in real GDP for all of 2001 was 1.2 percent. That compares to a 4.1 percent annual growth rate in both 1999 and in 2000.

Real Gross Domestic Product (GDP) during the first quarter (January through March) of 2002 increased at an annual rate of 5.8 percent. This is the advance estimate for the first quarter and will be revised in the preliminary and final estimates over the next 2 months. During 2001, real GDP changed at annual rates of +1.3 percent, +0.3 percent, -1.3 percent and +1.7 percent for each quarter respectively.
This is the fastest rate of growth of GDP since the fourth quarter of 1999. The growth rate in real GDP for all of 2001 was 1.2 percent. That compares to a 4.1 percent annual growth rate in both 1999 and in 2000.
Why are Changes in Real Gross Domestic Product Important?
The measurement of the production of goods and services produced each year permits us to evaluate our monetary and fiscal polices, our investment and saving patterns, the quality of our technological advances, and our material well-being. While rates of inflation and unemployment and changes in our income distribution provide us additional measures of the successes and weaknesses of our economy, none is a more important indicator of our economy's health than rates of change in real GDP.
Changes in real GDP are discussed in the press and on the nightly news after every monthly announcement of the latest quarter's data or revision. This current rather high increase in real GDP will be discussed in news reports as a sign that the economy may have already come out of the recession that began in March of last year.
Real GDP trends are prominently included in discussions of potential slowdowns and economic booms. They are featured in many discussions of trends in stock prices. Economic commentators use falls in real GDP as indicators of recessions. The most popular (although inaccurate) definition of a recession is at least two consecutive quarters of declining real GDP. See below for a discussion of the current recession.
Most important, changes in real GDP per capita provide our best measures of changes in our material standards of living.
Goals of Case Study
The goals of the GDP Case Studies are to provide teachers and students:
- access to easily understood, timely interpretations of monthly announcements of rate of change in real GDP and the accompanying related data in the U.S. economy;
- descriptions of major issues surrounding the data announcements;
- brief analyses of historical perspectives;
- questions and activities to use to reinforce and develop understanding of relevant concepts; and
- a list of publications and resources that may benefit classroom teachers and students interested in exploring inflation.
Definition of Gross Domestic Product
Gross Domestic Product (GDP) is one measure of economic activity, the total amount of goods and services produced in the United States in a year. It is calculated by adding together the market values of all of the final goods and services produced in a year.
- It is a gross measurement because it includes the total amount of goods and services produced, some of which are simply replacing goods that have depreciated or have worn out.
- It is domestic production because it includes only goods and services produced within the U.S.
- It measures current production because it includes only what was produced during the year.
- It is a measurement of the final goods produced because it does not include the value of a good when sold by a producer, again when sold by the distributor, and once more when sold by the retailer to the final customer. We count only the final sale.
Changes in GDP from one year to the next reflect changes in the output of goods and services and changes in their prices. To provide a better understanding of what actually is occurring in the economy, real GDP is also calculated. In fact, these changes are more meaningful, as the changes in real GDP show what has actually happened to the quantities of goods and services, independent of changes in prices.
The growth in real GDP at the end of the 1990s has been relatively high when compared with the early part of the 1990s. However, during the last two quarters of 2000 and the first three quarters of 2001, the rate of growth of real gross domestic product slowed significantly. During the third quarter of 2001, real GDP was actually negative for the first time since 1993.
The Federal Reserve has responded to slowing growth and the recession, beginning in March 2001, by reducing the target federal funds rate by 475 basis points (4.75%) from January 2001 to December 2001. (See the January 30, Federal Reserve System and Monetary Policy Case). The effects of stimulative monetary policy and the resulting low interest rates helped increase consumer spending over the past two quarters, partially responsible for the increase in real GDP in the fourth quarter of 2001 and the first quarter of 2002.
The price index for GDP increased at a rate of 0.8 percent during the first quarter of 2002, compared to a decline of 0.1 percent during the fourth quarter of 2001. It increased at an annual rate of 2.2 percent for 2001, compared to 2.3 percent for 2000.
The rate of increase in real GDP has been higher in the last several years than in the first part of the 1990s and much of the 1970s and 1980s. Economic growth, as measured by average annual changes in real GDP, was 4.4 percent in the 1960s. Average rates of growth decreased during the 1970s (3.3%), the 1980s (3.0%), and the first half of the 1990s (2.2%). In the last five years of the 1990s, the rate of growth in real GDP increased to 3.8 percent, with the last three years being at or over 4.1 percent per year.
The upward trend in economic growth over the past decade has been accompanied by increases in the rates of growth of consumption spending, investment spending, and exports. Productivity increases, expansions in the labor force, decreases in unemployment, and increases in the amount of capital have allowed real GDP to grow at the faster rates. During this same time period, consumers have reduced their savings. Personal savings as a percentage of disposable income had fallen to one-half of one percent during the last several quarters before it rose this quarter to 2.1 percent.
Details of the fourth-Quarter Changes in Real GDP
Real GDP increased by 5.8 percent in the first quarter of 2002 compared to a decline of 1.7 percent in the fourth quarter of 2001. Consumption continued to increase during the quarter, but at a slower rate than in the fourth quarter. Government spending also increased at a slower rate than the fourth quarter, but included a quite large increase in federal spending on national defense. Exports increased, but imports increased by an even larger amount with the net effect being a reduction in real GDP.
The increase in consumption spending was primarily due increases in non-durable goods and services. For 2001, consumption spending increased at a rate of 3.1 percent, compared to 4.8 percent in 2000 and 5.0 percent in 1999.
Real investment increased at an annual rate of 22.6 percent during the first quarter of 2002, compared to a decrease of 23.5 percent in the fourth quarter of 2001. The most important causes of that increase were the rise in residential investment and the significantly smaller reduction in inventories. For all of 2001, investment spending decreased 8.0 percent. The 15.7 percent increase in residential investment, but this was slightly offset by continued declines in non-residential fixed investment.
The effects of the changes in inventories are not always easy to interpret. The previous quarter included a reduction in inventories of almost $120 billion. This quarter saw a reduction in inventories of only $36 billion. Inventory reductions are counted as a negative investment - a reduction in the capital stock. As a much smaller amount was subtracted from the total amount of fixed investment, total investment actually increased during the quarter. (Investment in the fourth quarter was equal to $1,622 billion minus $120 billion, that is $1,502 billion. Investment in the first quarter of 2002 was equal to $1,621 billion minus $36 billion, which is $1,595 billion.)
Exports increased by 6.8 percent (compared to a decrease of 10.9 percent in the fourth quarter) and imports increased by 15.5 percent (compared to a decrease of 7.5 percent in the fourth quarter). Thus net exports fell slightly during the quarter.
Monetary policy has been used to encourage consumers to increase spending and businesses to increase investment. The short-run effects of both the monetary policy and the increase in government spending should be some stimulus to spending. In the fourth quarter of 2001, the effects of low interest rates (and zero-percent financing by many car dealerships) are seen in the increased purchases of durable goods such as automobiles and appliances. In the first quarter of 2002, the effects of monetary policy are contributing to inventory expansion.
On November 26, The National Bureau of Economic Research announced though its Business Cycle Dating Committee that it had determined that a peak in business activity occurred in March of 2001. That signals the official beginning of a recession.
The NBER defines a recession as a "significant decline in activity spread across the economy, lasting more than a few months, visible in industrial production, employment, real income, and wholesale-retail trade." The current data show a decline in employment, but not as large as in the previous recession. Real income growth has slowed but not declined. Manufacturing and trade sales and industrial production have both declined and have been doing so for some time. As seen during this quarter, consumers are increasing their spending and there is significant speculation that we are currently coming out of the recession.
The last recession began in July of 1990 and ended in March of 1991, a period of eight months. However, the beginning of the recession was not announced until April of 1991 (after the recession had actually ended). The end of the recession was announced in December of 1992, almost 21 months later. One of the reasons the end of the recession was so difficult to determine was the economy did not grow very rapidly even after it came out a period of falling output and income.

Changes in Nominal Gross Domestic Product
Nominal GDP - that is, GDP measured in current prices - increased at annual rate of 6.7 percent in the first quarter of 2001 to a level of $10,431.3 billion. The rate of change in nominal GDP (6.7%) equals the change in real GDP (5.8%) plus the change in prices of goods included in nominal GDP (0.8%). The latter is represented by the GDP deflator, sometimes described as the GDP price index. (The numbers do not add up exactly due to errors in rounding).
A Hint About News Reports
Many news reports simply use "gross domestic product" as a term to describe this announcement. The actual announcement focuses on the REAL gross domestic product, and that is the meaningful part of the report. In addition, newspapers will often refer to the rate of growth during the most recent quarter and will not always refer to the fact that it is reported at annual rates of change. This is contrasted to the reports of the consumer price index, which are reported at actual percentage changes in the index for a single month, and not at annual rates.
[Economic growth is a function of the technological innovation and the amount and quality of labor and capital in the economy:
As more people are employed, the amount of capital increases, education levels increase, the quality of capital changes, or the technology increases, the productive capacity of the economy increases. Therefore, the economy can increase its output giving consumers more disposable income, promoting an increase in consumption spending, and providing resources for business to use for further investment and government to use to provide public goods and services.
Increased labor force participation increases output. Expanded, improved education creates more productive workers. Business and government spending on research and development enhance our abilities to produce and allow each worker to become more productive, increasing incomes for all. Finally, to achieve a higher level of GDP in the future, consumers need to limit consumption spending and increase savings today, permitting businesses to invest more in capital goods. If resources are invested into building an economy now, future generations will enjoy a higher level of economic growth; our businesses will produce more goods and consumers can purchase more goods. Expansion of output at rates faster than our population growth is what gives us the opportunity to enjoy higher standards of living.]
Explanations of GDP and its Components
It is common to see the following equation in economics textbooks:
|GDP = C + I + G + NX|
Consumption spending (C) consists of consumer spending on goods and services. It is often divided into spending on durable goods, non-durable goods, and services. These purchases accounted for 70 percent of GDP in the first quarter.
- Durable goods are items such as cars, furniture, and appliances, which are used for several years (11%).
- Non-durable goods are items such as food, clothing, and disposable products, which are used for only a short time period (20%).
- Services include rent paid on apartments (or estimated values for owner-occupied housing), airplane tickets, legal and medical advice or treatment, electricity and other utilities. Services are the fastest growing part of consumption spending (39%).
Investment spending (I) consists of non-residential fixed investment, residential investment, and inventory changes. Investment spending accounts for 17 percent of GDP, but varies significantly from year to year.
- Non-residential fixed investment is the creation of tools and equipment to use in the production of other goods and services. Examples are the building of factories, the production of new machines, and the manufacturing of computers for business use (17%).
- Residential investment is the building of a new homes or apartments (4%).
- Inventory changes consist of changes in the level of stocks of goods necessary for production and finished goods ready to be sold (-1%).
Government spending (G) consists of federal, state, and local government spending on goods and services such as research, roads, defense, schools, and police and fire departments. This spending does not include transfer payments such as Social Security, unemployment compensation, and welfare payments, which do not represent production of goods and services (18%).
Net Exports (NX) is equal to exports minus imports. Exports are items produced in the U.S. and purchased by foreigners (11%). Imports are items produced by foreigners and purchased by U.S. consumers (16%). Thus, net exports (exports minus imports) are negative, about -5% of the GDP. (For more information on the balance of trade, see the Trade Report case study.)
Saving and GDP
During the first quarter of 2002, personal saving as percentage of disposable income increased to 2.1 percent from 0.4 percent in the fourth quarter of 2001. Other industrialized nations such as France, Germany, Italy, Spain and Japan all have saving rates of over 10 percent. A low saving rate means that there are fewer resources to finance investment in the economy and, as a result, the growth rate in investment may be subdued. Over the past several years, foreign capital has funded investment in the U.S. However, as the global economy strengthens, foreign investors have a wider range of options for investing and this source of investment capital may weaken, hurting investment unless the U.S. saving rate increases.
GDP as a Measure of Well-being
Changes in real GDP are a more accurate representation of meaningful economic growth than changes in nominal GDP, because changes in real GDP represent changes in quantities produced, while prices are held constant. Real GDP per capita is even more relevant because it measures goods and services produced per person and thus approximates the amount of goods and services each person can enjoy. If real GDP grows, but the population grows faster, then each person, on average, is actually worse off than the change in real GDP would indicate.
Consider the table below. While the mainland part of China has a GDP of $991 billion, its GDP per capita is only $791.30. Hong Kong has a much smaller GDP of $159 billion. However, its GDP per capita is much higher at $23,639.58. Other nations, such as France and Germany, may have quite different GDPs, but GDPs per capita that are very close.
|Country||Population||GDP (billions)||Per Capita GDP|
GDP per capita is not a perfect estimate of well-being. When individuals grow their own food, build their own houses and sew their own clothes, they are not producing goods and services to be sold in a marketplace and therefore GDP does not change. As a result, many countries South America and Africa have a low GDP per capita that underestimates their well-being.
(The comparisons in the above table are of nominal GDP per capita, not real GDP per capita. As we are comparing per capita figures for the same year there is no need to deflate the nominal figures into real figures.)
The U.S. as a Wealthy Country
An alternative way of comparing the size of world economies is to calculate the percentage of the world GDP (approximately $32 trillion) produced in each country and compare that to the percentage of the world's population living in each country. As seen in the table above, the top ten countries in terms of gross domestic product comprise 75 percent of the global GDP with only 35 percent of the world's population. The U.S. alone produces a third of the goods bought and sold around the world with only 4.7 percent of the world's population. There are significant differences in the wealth of nations and the income of its citizens.
Revisions in GDP Announcements
Real GDP for each quarter is announced three times. The month following the end of the quarter is described as the advance GDP; the second announcement or revision is described as the preliminary announcement; and the third month is the final. While labeled as the final version, even it will eventually be revised after the final data for the year are published. Since 1978, the advance estimates have been revised an average increase of 0.5 percent in the rate of growth of GDP and the preliminary estimates have been revised by an average increase of 0.3 in the rate of growth of GDP.
Revisions in inventory investment and the international trade data are often the causes of changes in the GDP figures. Because changes in inventories and international trade data make up significant portions of the current report, one should be particularly cautious in using the "advance" and "preliminary" figures.
[GDP fails to account for many forms of production that improve a person's well being. For example, if you make a meal at home, the labor is not included. However, if you were to go out to a restaurant and consume that same meal, the labor is included in GDP. Unpaid work at home or for a friend and volunteer work is not included and thus GDP does not reflect production of all we produce.
External effects of production, such as pollution, are not subtracted from the value of GDP. Although two countries may have similar GDP growth rates, one country may have significantly cleaner water and air, and therefore is truly better off than the other country. If as economic growth accelerates, producers begin to employ production techniques that create more pollution, the effects of the growth are overstated.
GDP includes police protection, new prisons, and national defense as goods and services. It is not always clear that if we have to devote increased resources for such purposes that we are better off as a result.
GDP includes the effects of price changes. An increase in GDP due solely to inflation does not signal an improvement in living standards. Real GDP is a better measure. Nor does GDP reflect population growth. Changes in the income distribution are not measured. It is also difficult to compare rates of growth for different countries, as countries use different means of estimating income and price levels in their economy.
There are a variety of other weaknesses and inaccuracies, but GDP accounting is the best that we have. Real GDP does provide sound signals as to the direction of change of a selected large part of what we produce each year. Government statisticians and academics are constantly working to improve its accuracy and its ability to reflect our well-being.]
Components of GDP
Determine if each of the items listed below should be included in GDP and under which component or components: Consumption, Investment, Government, Exports or Imports.
- A stereo produced and sold in the US by a Japanese company
[Consumption - A stereo produced and purchased in the US is counted as a consumption good and not an import, regardless of the ownership of the company.]
- College tuition
- Social Security payments
[Not included - This is a type of transfer payment and is not included in GDP, because it does not represent the production of goods and services.]
- Microsoft stock purchased from Microsoft
[Not included - The purchase of a stock is a transfer of money and does not represent the production of goods and services.]
- A space shuttle launch
- The purchase of a plane ticket to London on British Airways
[Imports and consumption - This is an import and a consumption good because it is the consumption of a good produced outside the US by a consumer in the US]
- The purchase of a US Treasury Bond by an individual
[Not included - The purchase of a US Treasury Bond is a transfer of money from the consumer to the Treasury and does represent the production of goods and services.]
- A new factory
- The sale of a previously occupied house
[Not included - Only current construction is counted in GDP. The house was accounted for in GDP when it was originally built. When resold later, it does not represent the production of goods and services.]
- A bottle of French wine, sold in the US
[Imports and consumption - This is both an import and a consumption good, because it was produced outside the US and purchased by a consumer in the US for personal consumption.]
- A television produced, but not sold.
[Investment - A good that is produced but not sold is counted as an increase in business inventories, a category of investment. They are counted in GDP because they represent the current production of goods; they are a business investment to be sold in the future.]
- A home cooked meal
- A dinner at a restaurant
- A computer produced in the US and sold in Canada
- A new interstate
Other Questions for StudentsNote: You may use this reproducible to discuss these questions in class.
- Given the following data (in billions of current dollars), calculate the current level of gross domestic product.
Consumption spending $7,000 Social security payments 500 Income tax receipts 1,000 Exports 1,100 Business purchases of new factories and equipment and changes in inventories 1,500 Federal government spending on goods and services 550 Construction of new homes 200 State and local spending on goods and services 1,300 Imports 1,500 Wages 6,000
[Gross domestic product will equal consumption spending ($7,000), plus investment spending ($1,500 + 200), plus government spending on goods and services ($550 + 1,300), plus exports ($1,100), minus imports ($1,500). GDP = $10,150 billion, or $10.150 trillion.
Social security payments are not included, as they are transferring income from one set of individuals, taxpayers, to another, social security recipients. Goods and services are not produced. For basically the same reasons, taxes are not included.
Construction of new homes is part of investment spending. Wages are not included.]
- If gross domestic product increases by 10 percent over a year, are we better off? Why or why not?
[Perhaps we are better off. Part of the answer depends upon what is happening to prices and what is happening to population. If prices and population together are rising by more than 10 percent per year, than we, on average, are worse off. We have fewer goods and services per person.]
- Increases in real GDP represent more production of goods and services. Why would the Federal Reserve ever undertake a policy to slow down the rate of growth in production?
[As more is produced, more labor is hired. Increasing demand for labor will eventually cause wages to begin to rise. Although workers benefit, the increased wages will eventually put upward pressure on the prices businesses have to charge to cover their new higher costs. If the Federal Reserve is concerned with rising inflationary pressures, they will be concerned with the rapid rates of increase in GDP.]
- If consumers begin to purchase automobiles manufactured abroad instead of those manufactured in the US, what will happen to real GDP? Will the answer be different if consumers are simply increasing their spending and those purchases are of automobiles manufactured abroad?
[Consumption spending will remain the same; however, imports will increase. Real GDP in the US will decrease. In the second instance, consumption spending increased, but imports increased by an equal amount. Real GDP does not change. The components do change.]
- Why are wages and profits not included in gross domestic product?
[Gross domestic product includes all of the production of goods and services in a year. Production of consumption, investment, government, and net export goods is included. Therefore, wages are not added to the total amounts of production when calculating GDP. But, production also generates income. Every dollar that is spent on goods and services eventually becomes income to someone - the workers, the owners, and the lenders. An alternative way of calculating GDP is to add all of the incomes earned by all participants in the economy.]
