Return

The seasonally adjusted rate of change in the consumer price index during the month of March 2002 was 0.3 percent (an increase of three-tenths of one percent). The rate of increase in the consumer price index over the past twelve months was 1.2 percent. In March, the core consumer price index, which excludes energy and food prices, increased by 0.1 percent.

Inflation

The Consumer Price Index for All Urban Consumers increased 0.1 percent in October on a seasonally adjusted basis. The core inflation rate increased the same amount. For the previous 12 months, the index increased 1.7%, the same rate as reported in the September report.

Employment and Unemployment

According to the October report of the Bureau of Labor Statistics, the unemployment rate fell from 5.9% to 5.8%, and the number of individuals unemployed also decreased. Total nonfarm employment rose by 214,000 in October. Employment gains were concentrated in retail trade, food services and health care.

Real GDP

The advance estimate for real GDP growth in the third quarter of 2014 was 3.5%, a decrease from the revised second quarter growth of 4.6%. Inventory investment reduced third quarter growth, while it added to second quarter growth. In addition, consumer spending increased at a lower rate in the third quarter, compared to the second. Finally, business investment increased in the third quarter, but at a lower rate than in the second quarter.

Federal Reserve

The FOMC believes that the labor market has shown considerable improvement and the risks of inflation rising above its 2% target are low. Therefore, the Federal Reserve announced plans to end its purchase of financial assets. In addition, the federal funds rate will remain at its current low level. However, the FOMC has signaled its willingness to increase the federal funds rate if inflation shows signs of rising above the 2% target.


Announcement

In March, the core consumer price index, which excludes energy and food prices, increased by 0.1 percent.

Goals of the Case Study

The goals of the Inflation Case Studies are to provide teachers and students:

  • access to easily understood, timely interpretations of monthly announcements of rate of change in prices 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.

Data Trends

In March, the Consumer Price Index rose by 0.3 percent, slightly higher than the 0.2 percent increase in both January and February. In March, large increases in the prices indices of energy (3.8%), apparel (1.2%) and transportation (1.2%) caused the inflation rate to increase. The large increase in both the energy and transportation indices was due to rising gasoline prices in March. These increases were countered by decreases in the prices of education, communication and cigarettes.

The core rate of inflation represents the consumer price index without the influences of changes in the price indices for food and energy, which can fluctuate widely from month to month. While food and energy prices increased during March, the tobacco index declined, causing a deceleration in the core rate of inflation to 0.1 percent. This compares to a 0.2 percent increase in the core rate of inflation for January and 0.3 percent during February.

Figure 1 below shows recent inflation data reported for each month. Inflation increased in 1999 and 2000 when compared to1998, slowed throughout much of 2000, and then increased slightly at the beginning of 2001. If inflation is considered over the eight quarters of 2000 and 2001, the annual rates of change were 6.1, 2.6, 2.8, 2.1, 4.0, 3.7, 0.7 and -2.0 percent. The rate of inflation increased in January through May of 2001. Inflation has been decreasing since that point. During the fourth quarter, the price index actually decreased. What is really quite obvious from figure 1 is that the changes in inflation from month to month are much more dramatic from 1999 on, when compared to 1998. The increased volatility is primarily due to fluctuations in the prices of oil and food. The core rate of inflation (excluding food and energy) gives a much better idea of longer-term trends and that is why it is often featured in news reports. See figure 2.

Figure 1: Monthly Inflation in Consumer Prices at Annual Rates

Figure 2: Monthly Core Inflation Rate (excludes food and energy)

Compared to the rates of inflation in the 1970s and much of the 1980s, the current rate of inflation is quite low. See figure 3 below. Few observers would describe the most recent rates as high and they are not, when compared to those of the past thirty years. Other observers would describe the current experience as no or zero inflation.

Definitions of Inflation and the Consumer Price Index

Inflation is a sustained increase in the overall level of prices. The most widely reported measurement of inflation is the consumer price index (CPI). The CPI measures the cost of a fixed basket of goods relative to the cost of that same basket of goods in a base (or previous) year. Changes in the price of this basket of goods approximate changes in the overall level of prices paid by consumers.

The seasonally adjusted consumer price index in March was 178.6. The price index was equal to 100 during the period from 1982 to 1984. The interpretation is that prices in market basket of goods purchased by the typical consumer increased from the 1982-1984 period to March 2002 by 78.6 percent.

Inflation is usually reported in newspapers and television news as percentage changes in the CPI on a monthly basis. For example, the CPI in March was 178.6, compared to 178.0 in February. The increase in prices from February to March was (178.6-178.0) / 178.0 = 0.0034 or a monthly inflation rate of .34 percent. It is reported to the nearest one-tenth of a percent, in this case, 0.3 percent. To convert this into an annual rate, you could simply multiply by 12. This approximates an annual inflation rate of (0.3)(12) = 3.6 percent. A slightly more accurate measurement of the annual inflation rate is to compound the monthly rate, or raise the monthly rate of increase, plus one, to the 12th power.

Costs of Inflation

Understanding the costs of inflation is not an easy task. There are a variety of myths about inflation. There are debates among economists about some of the more serious problems caused by inflation. A number of exercises from the Council for Economic Education (http://store.councilforeconed.org/), including student workbooks, and textbooks should help students think about the consequences of inflation.

  1. High rates of inflation mean that people and business have to take steps to protect their financial assets from inflation. The resources and time used to do so could produce goods and services of value. Those goods and services given up are a true cost of inflation.
  2. High rates of inflation discourage businesses planning and investment as inflation makes the forecasting of prices and costs. As prices rise, people need more dollars to carry out their transactions. When more money is demanded, interest rates increase. Higher interest rates can cause investment spending to fall, as the cost of investing is higher. The unpredictability associated with fluctuating interest rates makes customers less likely to sign long-term contracts as well.
  3. The adage "inflation hurts lenders and helps borrowers" only applies if inflation is not expected. For example, interest rates normally increase in response to anticipated inflation. As a result, the lenders receive higher interest payments, part of which is compensation for the decrease in the value of the money lent. Borrowers have to pay higher interest rates and lose any advantage they may have from repaying loans with money that is not worth as much as it was prior to the inflation.
  4. Inflation does reduce the purchasing power of money.
  5. Inflation does redistribute income. On average, individuals' incomes do increase as inflation increases. However, some peoples' wages go up faster than inflation. Other wages are slower to adjust. People on fixed incomes such as pensions or whose salaries are slow to adjust are negatively affected by unexpected inflation.

Causes of Inflation

Over short periods of time, inflation can be caused by a decrease in production or an increase in spending. Inflation resulting from an increase in aggregate demand or total spending is called demand-pull inflation. Increases in demand, particularly if production in the economy is near the full-employment level of real GDP, pull up prices. It is not just rising spending. If spending is increasing more rapidly than the capacity to produce, there will be upward pressure on prices.

Inflation can also be caused by increases in costs of major inputs used throughout the economy. This type of inflation is often described as cost-push inflation. Increases in costs push prices up. The most common recent examples are inflationary periods caused largely by increases in the price of oil. Or if employers and employees begin to expect inflation, costs and prices will begin to rise as a result.

Over longer periods of time, that is, over periods of many months or years, inflation is caused by growth in the supply of money that is above and beyond the growth in the demand for money.

Inflation, in the short run and when caused by changes in demand, has an inverse relationship with unemployment. If there are high levels of unemployment, then there is less, or at least a slower growth in, spending in the economy and the inflation is subdued. If there is low unemployment, then wages are increasing to attract workers to jobs and this creates upward pressure on prices, that is, inflation. That relationship disappears when inflation is primarily caused by increases in costs. Unemployment and inflation can then rise simultaneously.

Other Measures of Inflation

The GDP price index (sometimes referred to as the implicit price deflator). The GDP price index is an index of prices of all goods and services included in the gross domestic product. Thus the index is a measure that is broader than the consumer price index. The producer price index. This index measures prices at the wholesale or producer level. It can act as a leading indicator of inflation. If the prices producers are charging are increasing, it is likely that consumers will eventually be faced with higher prices for good they buy at retail stores.

A Market Basket of Goods and Services

The Consumer Price Index measures prices of goods and services in a market basket of goods and services that is intended to be representative of a typical consumer's purchases. The percentages that are currently used to describe the categories of goods and services that market basket are as follows.

Food and beverages   16 %   Recreation   6 %
Housing   41 %   Education   3 %
Clothing   4 %   Communication   3 %
Transportation   17 %   Other goods and services   4 %
Medical care   6 %        

The Future of Inflation

The Federal Reserve's report on economic conditions across the country is released in the "Beige Book" (named for its beige cover) two weeks prior to each meeting of the Federal Reserve Open Market Committee. The following is an excerpt from the Beige Book released on March 6, 2002, in preparation for the FOMC meeting on March 19, 2002.

"A majority of Federal Reserve districts report some signs of improvement in economic conditions in January and early February. The Boston, Philadelphia, Richmond, Atlanta, Minneapolis, and San Francisco districts note some pickup in activity, Chicago cites a more positive tone, and Kansas City and St. Louis say that economic activity is weak, but there are some bright spots. Cleveland indicates that although some positive signs continue to emerge, overall business conditions in the district have neither improved nor deteriorated compared with the end of last year. New York reports mixed signals, and Dallas notes continued weak activity.

"Most districts say that manufacturing activity is generally weak, but selected industries in some areas are showing more positive results. Boston, New York, Philadelphia, Atlanta, Dallas, Richmond, Kansas City, and San Francisco report modest improvements in retail sales recently compared with the end of last year. Retail results were more mixed in the other districts. Districts indicate that residential real estate markets are generally stronger than commercial markets. Reports on demand for bank loans are mixed across the districts. Warm, dry weather figures prominently in agricultural reports. Warm weather and the slow global economy have contributed to weaker energy demand.

"Labor markets continue to be slack in most districts, with many citing business contacts who have suspended bonuses, frozen wages, or skipped annual salary increases. However, contacts at temporary employment firms in several districts suggest employment is bottoming out, and new hires in selected occupations are said to be in short supply. While wage and price pressures are described as "subdued" to "largely nonexistent," business contacts in many districts mentioned rising health insurance costs.

"Firms in most districts indicate that their purchase and selling prices are generally stable, but Dallas reports upward pressure on services prices and declining prices for chemicals and paper, while Cleveland notes an increase in spot market prices for steel."

The Beige Book report can be found at:
www.federalreserve.gov/fomc/BeigeBook/2002/20020306/default.htm

Between January and December 2001, the Federal Reserve's Open Market Committee decided to lower the target federal funds rate eleven times, for a total decrease of 4.75% in the target federal funds rate. The discount rate was also lowered. At the most recent meetings on January 29/30 and on March 19, 2002, the Federal Reserve decided to leave the target federal funds rate unchanged. Below is an excerpt from the press announcement following the March 19, 2002 meeting.

"The Federal Open Market Committee decided today to keep its target for the federal funds rate unchanged at 1-3/4 percent.

"The information that has become available since the last meeting of the Committee indicates that the economy, bolstered by a marked swing in inventory investment, is expanding at a significant pace. Nonetheless, the degree of the strengthening in final demand over coming quarters, an essential element in sustained economic expansion, is still uncertain.

"In these circumstances, although the stance of monetary policy is currently accommodative, the Committee believes that, for the foreseeable future, against the background of its long-run goals of price stability and sustainable economic growth and of the information currently available, the risks are balanced with respect to the prospects for both goals."

An Exercise

There have been many news reports lately about the rising costs of college tuition. In 2000, the average cost of tuition at four-year private colleges was $16,233 compared to $17,123 in 2001. At four-year public institutions, the average tuition increased from $3,487 to $3,754. What was the rate of increase in tuition for public and private colleges? Did the real cost of tuition increase?

[One way to approach the exercise is to compare rates of increase in tuition with the rate of inflation. In essence, is tuition increasing at the same rate as inflation, at a faster rate, or at a slower rate?

The consumer price indexes for 2000 and 2001 were 172.2 and 177.1. To calculate the rate of inflation, find the increase and divide it by the 2000 index. (177.1-172.2)/172.2 = 2.8 percent. The increase in private college tuition was $890, or an increase of 5.5% ($890/$16,233). This exceeds the rate of inflation. The increase in public college tuition was $267, or an increase of 7.7% ($267/$3,487). This also exceeds the rate of inflation.

An alternative method that is often used to compare incomes, levels of output, and prices is to change the 2001 figure into terms of 2000 dollars. Thus we would create a new index showing the increase in prices. (177.1/172.2 = 1.028) To report the new number as an index, we normally multiply it by 100. However to express the 2001 figure in 2000 dollars, we divide the 2001data by the new index. (Thus for the public tuition, $3,754/1.028 = $3,652. Given that the 2001 tuition (in terms of 2000 dollars) is larger than the 2000 tuition (in terms of 2000 dollars), we would describe the change as an increase in the real cost of going to college.]

Case Study

  1. What are the key parts of the consumer price index and the Federal Reserve announcements?

    [During March, the consumer price index increased by 0.3 percent and the core index increased by 0.1 percent. The relative absence of price pressures this month is reflected in stable retail prices in many parts of the country. Over the last quarter of 2001, the decrease in the demand for labor, a decline in both investment spending and production, and the softening in business and household demand all contributed to an environment without significant inflationary pressures. As the economy strengthened in the first three months of the year, increases in spending may result in small increased pressures on prices.

    The Federal Reserve's main goals are economic growth and price stability. In this announcement it states, "The risks are balanced with respect to the prospects for both goals." Apparently, the Federal Reserve believes that the economy is stable with regards to both goals right now. The only reference in the March Beige Book to increased price pressures is to increasing health costs.]

  2. What are the relevant economic concepts?

    [Falling spending, the labor force, the full-employment level of real GDP, and inflation.]

  3. What are the policy options for the Federal Reserve?

    [The Federal Reserve can increase or decrease the target federal funds rate or leave the target federal funds rate at its current level.]

  4. Analyze current conditions with regard to policy options.

    [As unemployment rose during 2001, upward pressures on wages were decreased. However, as the labor markets begin to stabilize, the upward pressures on wages may become more important. The good news on the inflation front is that slowing growth in spending over the past year has resulted in reduced inflationary pressure. However, as the economy expands and spending starts to pick up, this might prompt concerns with inflation.

    Decreasing the target federal funds rate will likely lead to increases in investment spending and consumption spending, thereby increasing total spending in the economy. A decrease in interest rates decreases the cost of borrowing money for investment purposes. Investment spending increases as a result. The decrease in interest rates also decreases the costs of consumer borrowing to purchase automobiles and houses. With lower interest rates, spending in those markets is also likely to increase.

    The increases in investment and consumption spending result in a higher level of real GDP and a lower level of unemployment as businesses hire workers in order to satisfy the higher levels of spending. However, one side effect is that the increased spending may contribute to upward pressures on prices. Currently the Federal Reserve believes the economy is stable with respect to inflationary pressures. If inflationary pressures develop, the Federal Reserve could also increase the target federal funds rate which would curb inflation but decrease spending in the economy.]

  5. Based on the analysis and the goals, choose the correct economic policy.

    [Over the past year, the U.S. economy has undergone major changes. The US entered a recession in March 2001, which was accompanied by rising unemployment and slowing growth of GDP and productivity. (See the GDP Case Study.) The Federal Reserve responded to economic slowdown by lowering the target federal funds rate by 4.75%. Evidence that monetary policy is beginning to impact the economy is seen in the March 2002 Beige Book which indicates that labor markets are stabilizing, manufacturing is starting to rebound, and prices remain stable throughout most of the country.

    Many forecasters are suggesting that the economy will continue to strengthen and that a recovery will be apparent in mid-2002. The Federal Reserve currently believes that the economy is currently stable without economic weakness of inflationary pressures. However, if the Federal Reserve Open Market Committee continues to be concerned with a slowdown in the rate of growth in spending, the target federal funds rate could be further lowered at future meetings or between meetings. Or, if the Federal Reserve believes that inflationary pressures are developing, they can raise the target federal funds rate over the coming months.]

Other Questions for Students

You may use these questions for discussion your class or use this reproducible.

  1. Suppose the CPI was 160 for June 1999, and was 180 for June 2000. What is the corresponding annual rate of inflation?

    [The rate of increase in prices from June 1999 to June 2000 can be calculated by dividing the increase in the index by the initial level of the index. (These indexes show a much higher rate of inflation than the actual.)

    That is (180 - 160) / 160 = .125 or 12.5 percent. Because this is over a twelve-month period, it is an annual rate of inflation. More difficult interpretations are based on single-month changes. The results are normally converted to annual rates of inflation.]

  2. The base year of the CPI is 1982-1984. What has happened to prices since 1970 if the 1970 index was approximately 40 and if the current CPI were 160?

    [A current level of 160 would mean that consumer prices on average are 300 percent higher than their 1970 levels. The percentage increase is (160 - 40) / 40 = 3 or 300 percent. The base year period is not relevant to the calculation.]

  3. If prices increase by five percent in a year, what effect does this have on the purchasing power of individuals in the economy?

    [Students may answer that purchasing power goes down since their money is worth less, and consequently they cannot buy as many goods and services. The value of money does fall. However, they are ignoring the point that inflation affects wages as well. If average incomes and prices of goods and services have increased by five percent, the purchasing power of average income remains unchanged.]

  4. What are the costs of increased rates of inflation?

    [Large increases in the price level make it difficult for businesses to estimate future levels of revenues and costs of products. This may discourage some businesses from expanding and making investment decisions. In addition, real income may be redistributed as some incomes rise parallel to or faster than rates of inflation and others are slower to rise. Higher inflation rates lead to higher interest rates. As a result, more resources will be devoted to managing financial assets. Those resources could be used in times of lower inflation to produce other goods and services.]

  5. Calculate a consumer price index based on the following data. Calculate the indexes for the two years and determine the annual rate of inflation.

    The market basket consists of three goods: tennis balls, movie tickets, and fast-food restaurant meals.

     

    1999

     

    2000

     
     

    Quantity sold

    Price

    Quantity sold

    Price

    Tennis balls

    1000

    $1.00

    1500

    $ .90

    Movie tickets

    500

    8.00

    600

    9.00

    Fast-food meals

    400

    5.00

    500

    6.00

    [Price indexes are calculated by determining the cost of a fixed basket of goods. If we were to use the data in question five to calculate an index similar to the consumer price index, we would begin with the market basket. That market basket might be the consumption patterns of 1999. The cost of that market basket is the sum of the 1999 quantities times the 1999 prices. (1000 x $1.00) + (500 x $8.00) + (400 x $5.00) = $7,000. The cost of that SAME market basket in 2000 prices is (1000 x $.90) + (500 x $9.00) + (400 x $6.00) = $7,800. (Students are likely to have problems thinking about which market basket to use and which prices to use.)

    The 1999 base year index is the cost of the 1999 basket in 1999 prices divided by the cost of the base year (1999) basket. Or $7,000/$7,000 = 1. However, it is normally stated as 100. (Simply multiply the result by 100.)

    The 2000 year index is the cost of the 1999 basket in year 2000 divided by the cost of the base year (1999) basket in 1999. Or $7,800/$7,000 = 1.11. However, it is normally stated as 111. (Multiply the result by 100.)

    The rate of inflation is found by determining the percentage increase in the consumer price index between the two years. In this case, it is easy to see. The annual rate of inflation was 11 percent. {(111-100)/100 = .11 (or 11 percent)}]
