Current Key Economic Indicatorsas of March 7, 2015
The Consumer Price Index for All Urban Consumers (CPI-U) declined 0.7% in January on a seasonally adjusted basis. Over the last 12 months, the all-items price index fell 0.1%, the first 12-month negative change since the period ending October 2009. The gasoline index fell 18.7% and was the main cause of the decrease in the seasonally adjusted all items index. Core inflation rose 0.2% in January.
The unemployment rate fell to 5.5% in February of 2015, according to the Bureau of Labor Statistics release of March 6, 2015. Total nonfarm employment rose by 295,000. Job gains were particularly strong in food services and drinking places, professional and business services, and construction. Manufacturing employment also increased, although not as much as last month.
Real GDP increased 2.2% in the fourth quarter of 2014, according to the revised estimate released by the Bureau of Economic Analysis. This estimate is 0.4 percentage points less than the advance estimate. Consumer spending rose 4.2%, along with business investment, exports, and state and local government spending. Offsetting these gains were increases in imports and decreases in federal government spending.
In its January 28, 2015, statement, the FOMC cited the continued growth of the labor market, increased household and business spending, and below-target inflation as indicators of an economy that continues to recover. They expect below-target inflation to rise as oil prices and other "transitory" effects diminish. The statement reaffirmed the FOMC intention to keep the federal funds rate at its current low level. Notably, the FOMC added international variables to its list of factors to monitor for the timing of a rate increase.
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 rates 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.
Material that appears in italics is included in the teacher version only. All other material appears in the student version. Throughout the semester, the GDP cases will become progressively more comprehensive and advanced.
Real Gross Domestic Product (GDP) during the second quarter (July through September) of 2006 increased at an annual rate of 2.6 percent. This is the third and "final" estimate of the rate of change in the second quarter.
This compares to annual rates of increase of 3.3, 4.2, 1.8, and 5.6 percent in the previous four quarters and increases of 3.9 and 3.2 in 2004 and 2005.
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.
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 policies, our investment and saving patterns, the quality of our technological advances, and our material well-being. Changes in real GDP per capita provide our best measures of changes in our material standards of living.
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 increase in real GDP will be discussed in news reports as a positive sign of the strength of the current economy.
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 decreases 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 2001 recession.)
The increase at an annual rate of 2.6 percent during the second quarter is slower than we experienced in most of the recent quarters and is slower than the entire years of 2004 and 2005. While just for a single quarter, the slowing is not surprising given the steady increases in interest rates over the last two years. (See the latest Federal Open Market Committee case for more background.)
The rate of increase in real GDP has been not only higher in the last part of the 1990s than in the first half of the 1990s, but also when compared with 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 of the 1990s 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. Figure 2 also shows the average annual rate of growth of 3.1 percent since 1970.
The price index for GDP increased at a rate of 3.3 percent during the second quarter of 2006, compared to an identical increase of 3.3 percent during the first quarter of 2006. It increased at an annual rate of 3.0 percent for all of 2005. One of the reasons for the changes in policies of the Federal Reserve is to slow the rate of growth in spending and to lower the possibility of increasing inflation.
Details of the First-Quarter Changes in Real GDP
Real GDP increased at an annual rate of 2.6, a decrease from the rapid increase of 5.6 percent in the first quarter. All parts of GDP experienced slower growth in the quarter. Growth in consumption spending slowed from 4.8 to 2.6 percent. Investment spending grew as an annual rate of 7.8 percent in the first quarter; only 1 percent in the second. Government spending grew at 4.9 percent in the first and .8 percent in the second quarter. Export growth slowed from 14 to 6.2 percent. Imports also grew more slowly: 9.1 to 1.4 percent.
On November 2001, 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 signaled the official beginning of a recession. In July 2003, the committee reported its determination of the end of the recession as of November 2001.
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 slowed but did not decline. Manufacturing and trade sales and industrial production both declined and had been doing so for some time.
The previous 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. 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, very similar conditions to those of the current economy.
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.
Explanations of GDP and its Components
Gross domestic product consists of goods and services produced for consumption, for investment, for government, and for export. The GDP accounts are broken down into consumption spending, investment spending, government spending, and spending on U.S. exports. To arrive at the amount actually produced (that is, GDP) our spending on imports is subtracted from those other amounts of spending. Thus,
GDP = Consumption spending + investment spending + government spending + export spending - import spending
There is a slide that shows this equation.
Consumption spending consists of consumer spending on goods and services. It is often divided into spending on durable goods, non-durable goods, and services. These purchases currently account for 70 percent of GDP.
- Durable goods are items such as cars, furniture, and appliances, which are used for several years.
- Non-durable goods are items such as food, clothing, and disposable products, which are used for only a short time period.
- 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.
Investment spending 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.
- Residential investment is the building of a new homes or apartments.
- Inventory changes consist of changes in the level of stocks of goods necessary for production and finished goods ready to be sold.
Government spending 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 (19 percent) does not include transfer payments such as Social Security, unemployment compensation, and welfare payments, which do not represent production of goods and services. Federal defense spending now accounts for approximately 5 percent of GDP. State and local spending on goods and services accounts for 12 percent of GDP, while federal spending is 7 percent of GDP.
Exports are goods and services produced in the U.S. and purchased by foreigners - currently about 10 percent of GDP.
Imports are items produced by foreigners and purchased by U.S. consumers are equal to 16 percent of GDP. Net exports (exports minus imports) are negative and are about 6 percent of the GDP.
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.
Per Capita GDP
|China (Hong Kong)||
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.)
Revisions in GDP Annoucements
Real GDP for each quarter is announced three times. The month following the end of the quarter is described as the advance real 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 of the rate of growth in real GDP have been revised an average of 0.5 percent in the next month's preliminary estimate. The preliminary estimates have been revised by an average of an additional 0.3 percent.
Revisions in inventory investment and the international trade data are often the causes of changes in the GDP figures. Those data for the last month of the quarter are not available when the advance estimate of GDP is announced.
1. Given the following data (in billions of current dollars),
Social security payments
Income tax receipts
Federal government spending on goods and services
Construction of new homes
State and local spending on goods and services
Changes in inventories
Business purchases of new factories and equipment
a. W hat is the level of government spending in the calculation of GDP?
b. What is the level of investment?
c. What is the level of net exports?
d. Calculate the level of gross domestic product.
a. Government spending equals $2,000 ($750 plus $1,250).
Government spending is equal to the sum of federal spending on goods and services and state and local spending on goods and services. Social security payments are transfers of income from tax payers to social security recipients and do not represent the production of goods and services.
b. Investment equals $1,900 ($2,000 + 400 - 500).
New factories and equipment and construction of new homes are included in investment. However, since business inventories fell, we subtract $500 billion from investment in structures, equipment, and residential housing to get the investment portion of GDP.
c. Net exports equal a minus $500 ($2,000 - 2,500).
Net exports are exports minus imports. In this case, the economy has a balance of trade deficit.
d. GDP equals $10,150 billion ($7,000 + 1,850 + 1,700 - 400).
GDP equals consumption spending plus government spending on goods and services plus investment spending plus net exports.
2. If nominal GDP has increased by 4 percent and inflation was 3 percent, the amount of output has increased by 1 percent. The remaining (after inflation) increase in nominal GDP must be due to real output increases.
3. If nominal GDP increases by 5 percent and the amount of output increases by 4 percent, then prices must have increased by 1 percent.
4. Real GDP has not changed. Nominal GDP increased by 4 percent. Real GDP increased by 1 percent. So if population grew by 1 percent, per capita real GDP did not change.
5. Employment must have increased. Because output increased by more than the output per worker, it must take more workers to produce the increased output.
6. Productivity must have increased. If real GDP increases by more than the rate of increase in the number of workers, than output per worker must have increased.
- If gross domestic product increases by 10 percent over a year, are we better off? Why or why not?
- If consumers begin to purchase automobiles manufactured abroad instead of those manufactured in the U.S. , 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?
Answers for Discussion Questions
- 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.
- Consumption spending will remain the same; however, imports will increase. Real GDP in the U.S. 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.
