Unemployment Unemployment rate – The Current Population Survey is a joint project of the BLS and the Bureau of the Census – Every month, 1,600 CPS interviewers survey 60,000 households to establish job market status of each member of the household. – Working-age population (WAP) = all people aged 16 years and over not jailed, hospitalized, institutionalized nor in the U.S. Armed Forces. (WAP = L + those not in L ) – Labor force (L) is the number of people employed plus the number unemployed (L = E + U ). – The CPS counts as employed (E ) all those in the WAP who, during the prior week, either 1. Worked at least 1 hour in a paid job or 15 hours unpaid in family business. 2. Were not working but who had jobs from which they were temporarily absent. – The CPS counts as unemployed (U ) all those in the WAP who, during the prior week, 1. Weren’t working but were available for work, 2. Looked for work during the previous 4 weeks OR were waiting to be recalled to a job from which they had been laid off. – The unemployment rate: u = U . x 100% L Unemployment Year Labor Force 2001 143,768,917 2002 Employed = Unemployed u 136,939,333 6,829,583 4.75 144,856,083 136,480,917 8,375,167 5.78 2003 146,499,500 137,729,250 8,770,250 5.99 2004 147,379,583 139,239,750 8,139,833 5.52 2005 149,291,750 141,713,500 7,578,250 5.08 2006 151,412,500 144,420,083 6,992,417 4.62 2007 153,126,333 146,049,500 7,076,833 4.62 2008 154,329,250 145,368,417 8,960,833 5.81 Types of unemployment Frictional (uf ): workers temporarily between jobs because of a move/career change. uf + us = 5% Structural (us ): workers displaced by automation.

At any point in time, some workers lose their jobs and unemployed workers find jobs. If the probability of losing a job equals p, there are p E job losers. If the probability of finding a job equals q, there are q U job finders.

Why? The Internet is ineffective, used to meet UI job search requirements, or used by people who do not put in the time and effort to find work (selection bias). The Relationship Between the Probability of Finding a New Job and UI Benefits US increased UI benefits from 26 to 99 weeks .08 .06 .04 .02 .00 1 6 11 16 21 26 31 36 41 46 51 56 61 66 (Weeks of UI benefits) 71 76 81 86 91 96 101 • Before the 2008 recession, UI ended at 26 weeks. • The probability of finding a new job spikes when UI benefits are exhausted • The probability of finding a new job spikes again at 15 weeks after benefits are exhausted • Hence, UI benefits should lengthen the duration of unemployment spells Funding the UI System: Imperfect Experience Rating Tax rate 5.4% 0.1% 0 l0 l1 Firm layoff Rate in the Past UI is funded by payroll tax on employers—the more lay offs the higher the tax The state determines up to what level to tax payrolls In California, the first $7000 paid to employees is taxed at a rate of between 0.1% to 5.4% Funding the UI System: Imperfect Experience Rating Tax rate 5.4% 0.1% 0 l l0 l1 Firm layoff Rate in the Past If the firm has a layoff rate less than l0, for each employee, the firm pays a tax to the Federal UI fund equal to the lesser of (0.1%)(wh) or (0.1%)($7000) Funding the UI System: Imperfect Experience Rating Tax rate 5.4% t 0.1% 0 l0 l l1 Firm layoff Rate in the Past If the firm has a layoff rate between l0 and l1, for each employee, the firm pays a tax to the Federal UI fund equal to the lesser of (t)(wh) or (t)($7000) Funding the UI System: Imperfect Experience Rating Tax rate 5.4% 0.1% 0 l0 l1 l Firm layoff Rate in the Past If the firm has a layoff rate greater than l1, for each employee, the firm pays a tax to the Federal UI fund equal to the lesser of Hence, firms with high layoff rates are subject to perfect experience rating, meaning firms with low layoff rates(5.4%)(wh) subsidize firms with high layoff rates or (5.4%)($7000) Efficiency Wages and Unemployment The shirking model • • • If workers are equally productive in a perfectly competitive labor market, they get paid w* whether they – work productively (which is costly) – goof off or make long distance phone calls at work (shirk) Workers may shirk after they are hired because – their incentives are not perfectly aligned with the owner’s (principal-agent) – information about their performance is limited (asymmetric information) – getting fired after being caught doesn’t prevent them from working for someone else making w* (moral hazard) Solutions: – Increased monitoring (costly and not perfect) – Bonding (e.g., employee don’t get student loans paid off if they quit early) – Piece rate pay (brownnosers lobby supervisors for the ‘best’ working conditions) – Paying wage wNS that exceeds w* (efficiency wage), which makes being fired costly (Dw = wNS – w*) The Determination of the Efficiency Wage Dollars S w0 w* D E0 N U Employment If shirking is not a problem, the market clears at wage w*. Shirking may occur because fired workers can find work somewhere else making w*. At high unemployment (N – E0), workers toe the line at a slightly higher wage w0 because high unemployment attracts workers who will not shirk at w0. The Determination of the Efficiency Wage Dollars SNS S w1 w0 w* D E0 E1 N Employment U At low unemployment (N – E1) firms have to pay much more to inhibit shirking Hence the no-shirking supply curve is upward sloping, and asymptotically approaches S. The Determination of the Efficiency Wage Dollars SNS S wNS w* D ENS N Employment The efficient wage model suggests that some unemployment is necessary to keep employees in line (structural unemployment) Efficiency wage wNS is given by the intersection of the no-shirking supply curve and demand curve The Determination of the Efficiency Wage and Economic Contraction Dollars SNS S w0NS w1NS w0* D10 w1* E1 E0 N Employment A fall in output demand reduces labor demand, reducing the competitive wage. If firms pay an efficiency wage, the contraction also reduces the efficiency wage Efficiency wage theory suggests that wages are sticky because the decline in wNS is much smaller than the fall in w*. The Determination of the Efficiency Wage and UI Benefits Dollars SNS S wNS D w* E N Employment An increase in UI benefits decreases no-shirking labor supply and increases • the wage needed to inhibit shirking (wNS) • Unemployment (N – E) • The cost of getting caught shirking (wNS – w*) The Wage Curve: The Relation Between Wage Levels and Unemployment Across Regions Wage w1NS w0NS u1 u0 Unemployment Rate Efficiency wages may play an important role in unemployment Geographic regions that offer higher wage rates also tend to have lower unemployment rates Hence, the greater is the surplus of workers (u), the lower the wage??? Yes if shirking is problematic The Phillips Curve Recessionary Gap A recessionary gap occurs when GDP is less than potential GDP.

Recessions began in mid-1990 and in first quarter of 2001. The longest expansion in U.S. history ran from the March 1991 to March 2001. When GDP decreases The unemployment rate increases And a little later, the inflation rate decreases As real GDP increases toward potential GDP, unemployment falls toward its natural rate, which leads to an eventual rise in inflation.
