22 MONITORING JOBS AND INFLATION Each month, we chart the course of unemployment and inflation as measures of the health of the U.S. economy.  How do we measure the unemployment rate?  How do we measure the inflation rate? Are they reliable vital signs for the economy? As the U.S. economy slowly expanded after a recession in 2008 and 2009, job growth was weak and questions about the health of the labor market became of vital importance to millions of Americans. © 2014 Pearson Education  Employment and Unemployment Why Unemployment Is a Problem Unemployment results in Lost incomes and production Lost human capital The loss of income is devastating for those who bear it. Employment benefits create a safety net but don’t fully replace lost wages, and not everyone receives benefits. Prolonged unemployment permanently damages a person’s job prospects by destroying human capital. © 2014 Pearson Education  Employment and Unemployment Current Population Survey The U.S. Census Bureau conducts a monthly population survey to determine the status of the U.S. labor force. The population is divided into two groups: 1. The working-age population—the number of people aged 16 years and older who are not in jail, hospital, or some other institution 2. People too young to work (under 16 years of age) or in institutional care © 2014 Pearson Education  Employment and Unemployment The working-age population is divided into two groups: 1. People in the labor force 2. People not in the labor force The labor force is the sum of employed and unemployed workers. © 2014 Pearson Education  Employment and Unemployment To be counted as unemployed, a person must be in one of the following three categories: 1. Without work but has made specific efforts to find a job within the previous four weeks 2. Waiting to be called back to a job from which he or she has been laid off 3. Waiting to start a new job within 30 days © 2014 Pearson Education  Employment and Unemployment Figure 22.1 shows the labor force categories. In June 2012: Population: 314 million Working-age population: 243.4 million Labor force: 155.0 million Employed: 142.2 million Unemployed: 12.8 million © 2014 Pearson Education  Employment and Unemployment Three Labor Market Indicators  The unemployment rate  The employment-to-population ratio  The labor force participation rate © 2014 Pearson Education  Employment and Unemployment The Unemployment Rate The unemployment rate is the percentage of the labor force that is unemployed. The unemployment rate is (Number of people unemployed ÷ labor force)  100. In June 2012, the labor force was 155 million and 12.8 million were unemployed, so the unemployment rate was 8.2 percent. The unemployment rate increases in a recession and reaches its peak value after the recession ends. © 2014 Pearson Education  Employment and Unemployment The Employment-to-Population Ratio The employment-to-population ratio is the percentage of the working-age population who have jobs. The employment-to-population ratio is (Employment ÷ Working-age population)  100. In June 2012, the employment was 142.2 million and the working-age population was 243.4 million. The employment-to-population ratio was 58.45 percent. © 2014 Pearson Education  Employment and Unemployment The Labor Force Participation Rate The labor force participation rate is the percentage of the working-age population who are members of the labor force. The labor force participation rate is (Labor force ÷ Working-age population)  100. In June 2012, the labor force was 155 million and the working-age population was 243.4 million. The labor force participation rate was 63.7 percent. © 2014 Pearson Education  Employment and Unemployment Other Definitions of Unemployment The purpose of the unemployment rate is to measure the underutilization of labor resources. The BLS believes that the unemployment rate gives a correct measure. But the official measure is an imperfect measure because it excludes  Marginally attached workers  Part-time workers who want full-time jobs © 2014 Pearson Education  Employment and Unemployment Marginally Attached Workers A marginally attached worker is a person who currently is neither working nor looking for work but has indicated that he or she wants and is available for a job and has looked for work sometime in the recent past. A discouraged worker is a marginally attached worker who has stopped looking for a job because of repeated failure to find one. © 2014 Pearson Education  Employment and Unemployment Part-Time Workers Who Want Full-Time Jobs Many part-time workers want to work part time, but some part-time workers would like full-time jobs and can’t find them. In the official statistics, these workers are called economic part-time workers and they are partly unemployed. Most Costly Unemployment All unemployment is costly, but the most costly is long- term unemployment that results from job loss. © 2014 Pearson Education  Unemployment and Full Employment Unemployment can be classified into three types:  Frictional unemployment  Structural unemployment  Cyclical unemployment © 2014 Pearson Education  Unemployment and Full Employment Frictional Unemployment Frictional unemployment is unemployment that arises from normal labor market turnover. The creation and destruction of jobs requires that unemployed workers search for new jobs. Increases in the number of people entering and reentering the labor force and increases in unemployment benefits raise frictional unemployment. Frictional unemployment is a permanent and healthy phenomenon of a growing economy. © 2014 Pearson Education  Unemployment and Full Employment Structural Unemployment Structural unemployment is unemployment created by changes in technology and foreign competition that change the skills needed to perform jobs or the locations of jobs. Structural unemployment lasts longer than frictional unemployment. © 2014 Pearson Education  Unemployment and Full Employment Cyclical Unemployment Cyclical unemployment is the higher than normal unemployment at a business cycle trough and lower than normal unemployment at a business cycle peak. A worker who is laid off because the economy is in a recession and is then rehired when the expansion begins experiences cyclical unemployment. © 2014 Pearson Education  Unemployment and Full Employment “Natural” Unemployment Natural unemployment is the unemployment that arises from frictions and structural change when there is no cyclical unemployment. Natural unemployment is all frictional and structural unemployment. The natural unemployment rate is natural unemployment as a percentage of the labor force. © 2014 Pearson Education  Unemployment and Full Employment Full employment is defined as the situation in which the unemployment rate equals the natural unemployment rate. When the economy is at full employment, there is no cyclical unemployment or, equivalently, all unemployment is frictional and structural. © 2014 Pearson Education  Unemployment and Full Employment The natural unemployment rate changes over time and is influenced by many factors. Key factors are The age distribution of the population The scale of structural change The real wage rate Unemployment benefits © 2014 Pearson Education  Unemployment and Full Employment Real GDP and Unemployment Over the Cycle Potential GDP is the quantity of real GDP produced at full employment. Potential GDP corresponds to the capacity of the economy to produce output on a sustained basis. Real GDP minus potential GDP is the output gap. Over the business cycle, the output gap fluctuates and the unemployment rate fluctuates around the natural unemployment rate. © 2014 Pearson Education  Unemployment and Full Employment Figure 22.5 shows the output gap and … the fluctuations of unemployment around the natural rate. When the output gap is negative,... the unemployment rate exceeds the natural unemployment rate. © 2014 Pearson Education  Price Level, Inflation, and Deflation The price level is the average level of prices and the value of money. A persistently rising price level is called inflation. A persistently falling price level is called deflation. We are interested in the price level because we want to 1. Measure the inflation rate or the deflation rate 2. Distinguish between money values and real values of economic variables. © 2014 Pearson Education  Price Level, Inflation, and Deflation Why Inflation and Deflation Are Problems Low, steady, and anticipated inflation or deflation is not a problem. Unpredictable inflation or deflation is a problem because it Redistributes income and wealth  Lowers real GDP and employment  Diverts resources from production © 2014 Pearson Education  Price Level, Inflation, and Deflation Unpredictable changes in the inflation rate redistribute income in arbitrary ways between employers and workers and between borrowers and lenders. A high inflation rate is a problem because it diverts resources from productive activities to inflation forecasting. From a social perspective, this waste of resources is a cost of inflation. At its worst, inflation becomes hyperinflation—an inflation rate that is so rapid that workers are paid twice a day because money loses its value so quickly. © 2014 Pearson Education  Price Level, Inflation, and Deflation The Consumer Price Index The Consumer Price Index, or CPI, measures the average of the prices paid by urban consumers for a “fixed” basket of consumer goods and services. © 2014 Pearson Education  Price Level, Inflation, and Deflation Reading the CPI Numbers The CPI is defined to equal 100 for the reference base period. Currently, the reference base period is 19821984. That is, for the average of the 36 months from January 1982 through December 1984, the CPI equals 100. In June 2012, the CPI was 228.8. This number tells us that the average of the prices paid by urban consumers for a fixed basket of goods was 128.8 percent higher in June 2012 than it was during 19821984. © 2014 Pearson Education  Price Level, Inflation, and Deflation Constructing the CPI Constructing the CPI involves three stages:  Selecting the CPI basket  Conducting a monthly price survey  Calculating the CPI © 2014 Pearson Education  Price Level, Inflation, and Deflation The CPI Basket The CPI basket is based on a Consumer Expenditure Survey, which is undertaken infrequently. The CPI basket today is based on data collected in the Consumer Expenditure Survey of 2008. © 2014 Pearson Education  Price Level, Inflation, and Deflation Figure 22.6 illustrates the CPI basket. Housing is the largest component. Transportation and food and beverages are the next largest components. The remaining components account for 26 percent of the basket. © 2014 Pearson Education  Price Level, Inflation, and Deflation The Monthly Price Survey Every month, BLS employees check the prices of the 80,000 goods in the CPI basket in 30 metropolitan areas. Calculating the CPI 1. Find the cost of the CPI basket at base-period prices. 2. Find the cost of the CPI basket at current-period prices. 3. Calculate the CPI for the current period. © 2014 Pearson Education  Price Level, Inflation, and Deflation Let’s work an example of the CPI calculation. In a simple economy, people consume only oranges and haircuts. The CPI basket is 10 oranges and 5 haircuts. The table also shows the prices in the base period. The cost of the CPI basket in the base period was $50. © 2014 Pearson Education  Price Level, Inflation, and Deflation Table 22.1(b) shows the fixed CPI basket of goods. It also shows the prices in the current period. The cost of the CPI basket at current-period prices is $70. © 2014 Pearson Education  Price Level, Inflation, and Deflation The CPI is calculated using the formula: CPI = (Cost of basket at current-period prices ÷ Cost of basket at base-period prices)  100. Using the numbers for the simple example, CPI = ($70 ÷ $50)  100 = 140. The CPI is 40 percent higher in the current period than it was in the base period. © 2014 Pearson Education  Price Level, Inflation, and Deflation Measuring the Inflation Rate The major purpose of the CPI is to measure inflation. The inflation rate is the percentage change in the price level from one year to the next. The inflation formula is: Inflation rate = [(CPI this year – CPI last year) ÷ CPI last year]  100. © 2014 Pearson Education  Price Level, Inflation, and Deflation Personal Consumption Expenditure Deflator The PCE deflator equals (Nominal consumption expenditure ÷ Real consumption expenditure)  100 PCE deflator is a broader measure of the price level than the CPI because it includes all consumption expenditure. GDP Deflator GDP deflator is like the PCE deflator except it includes the prices of all goods and services that are counted in GDP. © 2014 Pearson Education  Price Level, Inflation, and Deflation The Real Variables in Macroeconomics We can use the deflator to deflate nominal variables to find their real values. For example, Real wage rate = (Nominal wage rate ÷ GDP deflator)  100 But not the real interest rate! It is different. © 2014 Pearson Education
