In 1948, the labor force participation rate for women 20 years and older was 32 percent By 1970, it had grown to 43 percent, and by 1997 it had reached 60 percent Since 1997, the figure has remained virtually constant at 60 percent Explanations: • Women may simply have run out of available time • Even with new technology, housework and childcare take time Conclusion: Because women provide more household services than men, it is understandable why their labor force participation may have reached a peak Copyright © 2012 Pearson Prentice Hall All rights reserved 6-8 CHAPTER Unemployment and Inflation 6.1 EXAMINING UNEMPLOYMENT (cont’d) Alternative Measures of Unemployment and Why They Are Important ● discouraged workers Workers who left the labor force because they could not find jobs FIGURE 6.3 Alternative Measures of Unemployment, February 2010 Including discouraged workers, marginally attached workers, and individuals working part time for economic reasons substantially increases measured unemployment in 2010 from 14.87 million to 26.18 million Copyright © 2012 Pearson Prentice Hall All rights reserved 6-9 CHAPTER Unemployment and Inflation 6.1 EXAMINING UNEMPLOYMENT (cont’d) Who Are the Unemployed? FIGURE 6.4 Selected U.S Unemployment Statistics, Unemployment Rates for February 2010 The incidence of unemployment differs sharply among demographic groups Copyright © 2012 Pearson Prentice Hall All rights reserved 6-10 CHAPTER Unemployment and Inflation 6.2 CATEGORIES OF UNEMPLOYMENT (cont’d) The Natural Rate of Unemployment ● natural rate of unemployment The level of unemployment at which there is no cyclical unemployment It consists of only frictional and structural unemployment ● full employment The level of unemployment that occurs when the unemployment rate is at the natural rate Copyright © 2012 Pearson Prentice Hall All rights reserved 6-14 CHAPTER Unemployment and Inflation 6.3 THE COSTS OF UNEMPLOYMENT ● unemployment insurance Payments unemployed people receive from the government Copyright © 2012 Pearson Prentice Hall All rights reserved 6-15 CHAPTER Unemployment and Inflation APPLICATION SOCIAL NORMS, UNEMPLOYMENT, AND PERCEIVED HAPPINESS APPLYING THE CONCEPTS #3: Are you less upset from being unemployed if unemployment is common in your peer group? Individuals not like to become unemployed A seven year British study showed that: ▪ Well-being declines when we become unemployed ▪ If employed, having peers lose their job also decreases happiness ▪ Interestingly, losing one’s job causes less of a decrease in well-being if peers were also unemployed ▪ In other words, misery loves company Why is this significant? ▪ The more unhappy an unemployed person is, the more aggressive they are about finding another job ▪ If your peer group is unemployed, you may be less aggressive about trying to find another job Copyright © 2012 Pearson Prentice Hall All rights reserved 6-16 CHAPTER Unemployment and Inflation 6.4 THE CONSUMER PRICE INDEX AND THE COST OF LIVING REAL-NOMINAL PRINCIPLE What matters to people is the real value of money or income—its purchasing power—not the face value of money or income ● Consumer Price Index A price index that measures the cost of a fixed basket of goods chosen to represent the consumption pattern of a typical consumer The CPI index for a given year, say year K, is defined as Copyright © 2012 Pearson Prentice Hall All rights reserved 6-17 CHAPTER Unemployment and Inflation 6.4 THE CONSUMER PRICE INDEX AND THE COST OF LIVING (cont’d) FIGURE 6.5 Components of the Consumer Price Index (CPI) Rent and food and beverages make up 44 percent of the CPI basket The remainder consists of other goods and services The CPI versus the Chain Index for GDP Copyright © 2012 Pearson Prentice Hall All rights reserved 6-18 CHAPTER Unemployment and Inflation 6.4 THE CONSUMER PRICE INDEX AND THE COST OF LIVING (cont’d) Problems in Measuring Changes in Prices ● cost-of-living adjustments (COLAs) Automatic increases in wages or other payments that are tied to the CPI Copyright © 2012 Pearson Prentice Hall All rights reserved 6-19 CHAPTER Unemployment and Inflation APPLICATION THE INTRODUCTION OF CELL PHONES AND THE BIAS IN THE CPI APPLYING THE CONCEPTS #4: How large is the bias in the CPI due to not immediately incorporating new goods? •Cell phones were introduced in 1983, but not included in the CPI until 1998 •According to Jerry Hausman of MIT, this resulted in an upward bias of the telecommunication component of the CPI of 0.8 to 1.9 percent •The reported increase in telecommunication prices during this period might have actually been a decrease of percent •Room air conditioners also took 15 years to be included •Since new products are constantly being introduced, the bias in the CPI can be large Copyright © 2012 Pearson Prentice Hall All rights reserved 6-20 CHAPTER Unemployment and Inflation 6.5 INFLATION ● inflation rate The percentage rate of change in the price level inflation rate = percentage rate of change of a price index Copyright © 2012 Pearson Prentice Hall All rights reserved 6-21 CHAPTER Unemployment and Inflation 6.5 INFLATION (cont’d) Historical U.S Inflation Rates  FIGURE 6.6 Price Index for U.S GDP, 1875–2009 After remaining relatively flat for 60 years, the price level began to steadily increase after World War II The price of a postage stamp in 1940 and 2009 illustrates the change in the overall price level that occurred 6-22 Copyright © 2012 Pearson Prentice Hall All rights reserved CHAPTER Unemployment and Inflation 6.5 INFLATION (cont’d) Historical U.S Inflation Rates Copyright © 2012 Pearson Prentice Hall All rights reserved 6-23 CHAPTER Unemployment and Inflation 6.5 INFLATION (cont’d) Historical U.S Inflation Rates  FIGURE 6.7 U.S Inflation Rate, 1950–2009, Based on Chain-Weighted Price Index Inflation reached its highest peaks in the postwar era during the decade of the 1970s when the economy was hit with several increases in oil prices In recent years, the inflation rate has been relatively low Copyright © 2012 Pearson Prentice Hall All rights reserved 6-24 CHAPTER Unemployment and Inflation 6.5 INFLATION (cont’d) The Perils of Deflation ● deflation Negative inflation or falling prices of goods and services Copyright © 2012 Pearson Prentice Hall All rights reserved 6-25 CHAPTER Unemployment and Inflation 6.6 THE COSTS OF INFLATION ● anticipated inflation Inflation that is expected ● unanticipated inflation Inflation that is not expected Copyright © 2012 Pearson Prentice Hall All rights reserved 6-26 CHAPTER Unemployment and Inflation 6.6 THE COSTS OF INFLATION (cont’d) Anticipated Inflation ● menu costs The costs associated with changing prices and printing new price lists when there is inflation ● shoe-leather costs Costs of inflation that arise from trying to reduce holdings of cash Unanticipated Inflation ● hyperinflation An inflation rate exceeding 50 percent per month Copyright © 2012 Pearson Prentice Hall All rights reserved 6-27 CHAPTER Unemployment and Inflation KEY TERMS anticipated inflation labor force Consumer Price Index (CPI) labor force participation rate cost-of-living adjustments (COLAs) menu costs cyclical unemployment natural rate of unemployment deflation seasonal unemployment discouraged workers shoe-leather costs frictional unemployment structural unemployment full employment unanticipated inflation hyperinflation unemployment insurance inflation rate unemployment rate Copyright © 2012 Pearson Prentice Hall All rights reserved 6-28 ... reserved 6-17 CHAPTER Unemployment and Inflation 6.4 THE CONSUMER PRICE INDEX AND THE COST OF LIVING (cont’d) FIGURE 6.5 Components of the Consumer Price Index (CPI) Rent and food and beverages... reserved labor force × 100 population 16 years and older 6-5 CHAPTER Unemployment and Inflation 6.1 EXAMINING UNEMPLOYMENT (cont’d) How Is Unemployment Defined and Measured?
