Unemployment Rate Employment is the number of people currently employed in the economy, either full time or part time. Unemployment is the number of people who are actively looking for work but aren’t currently employed. The labor force is equal to the sum of employment and unemployment.

Unemployment Rate The labor force participation rate is the percentage of the population aged 16 or older that is in the labor force. The unemployment rate is the percentage of the total number of people in the labor force who are unemployed.

Unemployment Rate Figure Caption: Figure 8(23)-1: The U.S. Unemployment Rate, 1948-2011 The unemployment rate has fluctuated widely over time. It always rises during recessions, which are shown by the shaded bars. It usually, but not always, falls during periods of economic expansion. Source: Bureau of Labor Statistics; National Bureau of Economic Research 5

Unemployment Rate Discouraged workers are nonworking people who are capable of working but have given up looking for a job because of the state of the job market. Marginally attached workers would like to be employed and have looked for a job in the recent past but are not currently looking for work. Underemployment is the number of people who work part time because they cannot find full-time jobs.

ECONOMICS IN ACTION Rocky Mountain Low In addition to estimating the unemployment rate for the nation as a whole, the U.S. government also estimates unemployment rates for each state. In July 2007 the unemployment rate in Montana, like that in other mountain states, was very low: just 2.7%. Montana was doing well mainly because the state’s booming oil business was creating new jobs even as the state’s aging population reduced the size of the labor force. This is from previous edition of the book.

ECONOMICS IN ACTION Rocky Mountain Low Michigan was at the opposite extreme. Layoffs by auto manufacturers, the traditional mainstay of Michigan’s economy, had given the state the highest unemployment rate in the nation: 7.2% in July 2007. This is from previous edition of the book.

ECONOMICS IN ACTION Rocky Mountain Low Figure Caption: Unemployment Rates Across America, July 2007 At any given time, unemployment rates vary considerably among states. In July 2007 the unemployment rate in Montana, like that in other mountain states, was very low: just 2.7%. Meanwhile, Michigan had a 7.2% unemployment rate. Source: Bureau of Labor Statistics. 9

Unemployment Rate Figure Caption: Figure 8(23)-2: Alternative Measures of Unemployment, 1994-2011 The unemployment number usually quoted in the news media counts someone as unemployed only if he or she has been looking for work during the past four weeks. Broader measures also count discouraged workers, marginally attached workers, and the underemployed. These broader measures show a higher unemployment rate—but they move closely in parallel with the standard rate. Source: Bureau of Labor Statistics. 10

Unemployment Rates of Different Groups, 2007 35% 30 25 20 15 10 5 33.1% 14.4% Figure Caption: Figure 8(23)-3: Unemployment Rates of Different Groups, 2007 Unemployment rates vary greatly among different demographic groups. For example, although the overall unemployment rate in August 2007 was 5.0%, the unemployment rate among African-American teenagers was 33.1%. As a result, even during periods of low overall unemployment, unemployment remains a serious problem for some groups.

Unemployment and Recessions, 1978-2011 Unemployment Rate Unemployment and Recessions, 1978-2011 Figure Caption: Figure 8(23)-4: Unemployment and Recessions, 1978-2011 This figure shows a close-up of the unemployment rate for the past 30 years, with the shaded bars indicating recessions. It’s clear that unemployment always rises during recessions and usually falls during expansions. But in both the early 1990s and the early 2000s, unemployment continued to rise for some time after the recession was officially declared over.

Unemployment Rate

ECONOMICS IN ACTION Failure to Launch Times of high unemployment are especially hard on new graduates, who often find it hard to get any kind of full-time job. How bad was it in March 2010? A study by researchers at the San Francisco Fed looked at the employment experience of college graduates aged 21-23.

ECONOMICS IN ACTION Failure to Launch Whereas the overall unemployment rate for college graduates 25 and older, even at its peak, was only about 5%, unemployment among these recent graduates peaked at 10.7%. And many of those who were employed were only able to get part-time jobs. In December 2007, at the beginning of the 2007-2009 recession, 83% of college graduates under the age of 24 who weren’t still in school were employed full time.

ECONOMICS IN ACTION Failure to Launch By December 2009 that number was down to just 72%. Quite simply, many college graduates were having a hard time getting their working lives started. A year later, the situation was starting to improve, but slowly: in December 2010, 74% of recent graduates had full-time jobs. The U.S. labor market had a long way to go before it was offering college graduates – and young people in general – the kinds of opportunities they deserved.

ECONOMICS IN ACTION

The Nature of Unemployment Workers who spend time looking for employment are engaged in job search. Frictional unemployment is unemployment due to the time workers spend in job search. Structural unemployment is unemployment that results when there are more people seeking jobs in a labor market than there are jobs available at the current wage.

The Nature of Unemployment Figure Caption: Figure 8(23)-8: Distribution of the Unemployed by Duration of Unemployment, 2007 In years when the unemployment rate is low, most unemployed workers are unemployed for only a short period. In 2000, a year of low unemployment, 45% of the unemployed had been unemployed for less than 5 weeks and 77% for less than 15 weeks. The short duration of unemployment for most workers suggests that most unemployment in 2000 was frictional. Source: Bureau of Labor Statistics. 19

Structural Unemployment The Effect of a Minimum Wage on the Labor Market Wage Rate Structural unemployment W F Minimum wage W E Figure Caption: Figure 8(23)-9: The Effect of a Minimum Wage on the Labor Market When the government sets a minimum wage, WF, that exceeds the market equilibrium wage rate, WE, the number of workers, QS, who would like to work at that minimum wage is greater than the number of workers, QD, demanded at that wage rate. This surplus of labor is considered structural unemployment. Quantity of Labor Q Q Q D E S 20

Structural Unemployment Minimum wage—a government-mandated floor on the price of labor. In the United States, the national minimum wage in 2010 was $8.25 an hour. Unions—by bargaining for all a firm’s workers collectively (collective bargaining), unions can often win higher wages from employers than the market would have otherwise provided when workers bargained individually.

Structural Unemployment Efficiency wages—wages that employers set above the equilibrium wage rate as an incentive for better performance. Side effects of government policies—public policies designed to help workers who lose their jobs; these policies can lead to structural unemployment as an unintended side effect.

The Natural Rate of Unemployment The natural rate of unemployment is the normal unemployment rate around which the actual unemployment rate fluctuates. It is the unemployment rate that arises from the effects of frictional plus structural unemployment. Cyclical unemployment is a deviation in the actual rate of unemployment from the natural rate.

The Natural Rate of Unemployment Natural unemployment = Frictional unemployment + Structural unemployment Actual unemployment = Natural unemployment + Cyclical unemployment

GLOBAL COMPARISON: Natural Unemployment Around the OECD Global Comparison: The Organization for Economic Cooperation and Development (OECD) is an association of relatively wealthy countries, mainly in Europe and North America but also including Japan, Korea, New Zealand, and Australia. Among other activities, the OECD collects data on unemployment rates in its member nations using the U.S. definition. The figure shows average unemployment, which is a rough estimate of the natural rate of unemployment, for select OECD members, over the period 1996–2006. The purple bar in the middle shows the average across all countries. The U.S. natural rate of unemployment appears to be somewhat below average; those of many European countries (including the major economies of Germany, Italy, and France) are above average. Many, but not all, economists think that persistently high European unemployment rates are the result of government policies, such as high minimum wages and generous unemployment benefits, which both discourage employers from offering jobs and discourage workers from accepting jobs, leading to high rates of structural unemployment.

FOR INQUIRING MINDS An Unemployment Lockdown? Most analysts believe that the natural rate of unemployment in the United States has fallen substantially since 1980; the Congressional Budget Office estimate has fallen from 6.2% to 4.8%. One factor is that many of those who would otherwise be counted as unemployed may be behind bars. Example from previous edition.

FOR INQUIRING MINDS An Unemployment Lockdown? Largely owing to changes in law-enforcement strategies, the number of American adults in jail or prison has risen from 503,586 in 1980 (0.5% of the labor force) to 2.3 million in 2007 (1.5% of the labor force). The rise in the prison population might have lopped about 0.2 percentage points off the natural rate of unemployment. Example from previous edition.

ECONOMICS IN ACTION Structural Unemployment in Eastern Germany A spontaneous popular uprising in 1989 overthrew the communist dictatorship in East Germany. After reunification, employment in East Germany plunged. The economy of the former East Germany has remained persistently depressed, with an unemployment rate of more than 16% in 2008. East Germany found itself suffering from severe structural unemployment. When Germany was reunified, it became clear that workers in East Germany were much less productive than their cousins in the west.

ECONOMICS IN ACTION Structural Unemployment in Eastern Germany The result has been a persistently large mismatch between the number of workers demanded and the number of those seeking jobs.

Inflation and Deflation The real wage is the wage rate divided by the price level. Real income is income divided by the price level.

Inflation and Deflation

Inflation and Deflation Shoe-leather costs are the increased costs of transactions caused by inflation. Menu cost is the real cost of changing a listed price.

Inflation and Deflation Unit-of-account costs arise from the way inflation makes money a less reliable unit of measurement. The nominal interest rate is the interest rate expressed in dollar terms. The real interest rate is the nominal interest rate minus the rate of inflation. Disinflation is the process of bringing the inflation rate down.

Disinflation in the United States

ECONOMICS IN ACTION Israel’s Experience with Inflation In the mid-1980s, Israel experienced a “clean” inflation: there was no war, the government was stable, and there was order in the streets. But policy errors led to very high inflation. The shoe-leather costs of inflation were substantial. Israelis spent a lot of time moving money in and out of bank accounts that provided high enough interest rates to offset inflation.

ECONOMICS IN ACTION Israel’s Experience with Inflation Businesses made efforts to minimize menu costs. For example, restaurant menus often didn’t list prices. It was hard for Israelis to make decisions because prices changed so much and so often.

Summary Inflation and unemployment are the main concerns of macroeconomic policy. Employment is the number of people employed; unemployment is the number of people unemployed and actively looking for work. Their sum is equal to the labor force, and the labor force participation rate is the percentage of the population age 16 or older that is in the labor force.

Summary The unemployment rate can overstate because it counts as unemployed those who are continuing to search for a job despite having been offered one (that is, workers who are frictionally unemployed). It can understate because it ignores frustrated workers, such as discouraged workers, marginally attached workers, and the underemployed.

Summary The unemployment rate is affected by the business cycle. The unemployment rate generally falls when the growth rate of real GDP is above average and generally increases when the growth rate of real GDP is below average.

Summary Job creation and destruction, as well as voluntary job separations, lead to job search and frictional unemployment. In addition, a variety of factors (such as minimum wages, unions, efficiency wages, and government policies designed to help laid-off workers) result in a situation in which there is a surplus of labor at the market wage rate, creating structural unemployment. As a result, the natural rate of unemployment, the sum of frictional and structural employment, is well above zero, even when jobs are plentiful.

Summary The actual unemployment rate is equal to the natural rate of unemployment plus cyclical unemployment. The natural rate of unemployment changes over time. Policy makers worry about inflation, as well as unemployment.

Summary Inflation does not, as many assume, make everyone poorer by raising the level of prices. That's because wages and incomes are adjusted to take into account a rising price level, leaving real wages and real income unaffected. However, a high inflation rate imposes overall costs on the economy: shoe-leather costs, menu costs, and unit-of-account costs.

Summary Inflation can produce winners and losers within the economy, because long-term contracts are generally written in dollar terms. Loans typically specify a nominal interest rate, which differs from the real interest rate due to inflation. A higher-than-expected inflation rate is good for borrowers and bad for lenders. A lower-than-expected inflation rate is good for lenders and bad for borrowers. Disinflation is very costly, so policy makers try to prevent inflation from becoming excessive in the first place.
