Learning Objectives • Understand the working of the labor market and factors contributing to unemployment • Learn about macroeconomic policies for reducing unemployment
Definitions used in Bangladesh Employed: A person who was either working during the previous week for one or more hours for pay or profit or working without pay in a family farm or enterprise during the week or found not working but had a job or business from which he/she was temporarily absent during the week
Definitions used in Bangladesh Unemployed: A person who is involuntarily out of gainful employment during the reference period but either has been actively looking for a job or was willing to work but not looking for work because of illness
Important Formulae Crude Activity Rate = Labor Force * 100% Population Refined Activity Rate = Labor Force * 100% Population ≥ 15yrs Unemployment Rate = Unemployed * 100% Labor Force
Natural Rate of Unemployment • The unemployment rate: the fraction of the civilian workforce that is unemployed • The “Natural” rate of unemployment: The average or long-run rate of unemployment around which the economy fluctuates. • In a recession, the actual unemployment rate rises above the natural rate. • In a boom, the actual unemployment rate falls below the natural rate. LECTURE 6 Unemployment
Natural Rate of Unemployment • 5-6% for the developed economies • Exists in the developing economies as well • Difficult to get rid of this type of unemployment • Thus when a country has 5-6% of unemployment, it is considered to be fully employed

Labor Force and Unemployment Rate Notation: L = workers in labor force E = employed workers U = unemployed workers U/L = unemployment rate LECTURE 6 Unemployment
Assumptions: 1. L is exogenously fixed (no population growth). 2. During any given month, s = fraction of employed workers that become separated from their jobs s is called the rate of job separation f= fraction of unemployed workers that find jobs fis called the rate of job finding s and fare exogenous LECTURE 6 Unemployment
s E f U The Transitions between Employment and Unemployment Employed Unemployed LECTURE 6 Unemployment
Definition: the labor market is in steady state, or long-run equilibrium, if the unemployment rate is constant. The steady-state condition is: # of employed people who lose or leave their jobs # of unemployed people who find jobs The Steady State Condition sE =f U LECTURE 6 Unemployment
Finding the “equilibrium” Unemployment Rate f U =sE =s(L –U ) =sL –sU Solve for U/L: (f + s)U = sL so, LECTURE 6 Unemployment
The “Natural” Rate of Unemployment • Therefore, the natural rate of unemployment is defined as: LECTURE 6 Unemployment
Class Exercise • Suppose • 1% of employed workers lose their jobs • 19% of unemployed workers find jobs • Find the natural rate of unemployment LECTURE 6 Unemployment
Answer • Each month, • 1% of employed workers lose their jobs (s = 0.01) • 19% of unemployed workers find jobs (f = 0.19) • The natural rate of unemployment: LECTURE 6 Unemployment
Any policy aimed at lowering the natural rate of unemployment must either reduce the rate of job separation (s) or increases the rate of job finding (f). Similarly, any policy that affects the rate of job separation (s) or the rate of job finding (f) also changes the natural rate of unemployment, Because: Policy Implications LECTURE 6 Unemployment
Why is there Unemployment? • If job finding were instantaneous (s = 0, f = 1), then all spells of unemployment would be brief, and the natural rate would be near zero. • There are two reasons why f < 1 and s > 0: 1.job search 2.wage rigidity LECTURE 6 Unemployment
Job Search & Frictional Unemployment • Frictional unemployment: The unemployment caused by the time it takes workers to search for a job • Occurs even when wages are flexible and there are enough jobs to go around • Occurs because • workers have different abilities, preferences • jobs have different skill requirements • geographic mobility of workers not instantaneous • flow of information about vacancies and job candidates is imperfect LECTURE 6 Unemployment
Sectoral Shifts • defintion: Changes in the composition of demand among industries or regions. • example: Technological changemore jobs repairing computers, fewer jobs repairing typewriters • example: A new international trade agreement labor demand increases in export sectors, decreases in import-competing sectors • Result: frictional unemployment LECTURE 6 Unemployment
Structural change over the long run - US LECTURE 6 Unemployment
Structural Change in Employment: Bangladesh LECTURE 6 Unemployment
More examples of Sectoral Shifts • Late 1800s: decline of agriculture, increase in manufacturing • Late 1900s: relative decline of manufacturing, increase in service sector • 1970s: energy crisis caused a shift in demand away from gas guzzlers toward smaller cars. LECTURE 6 Unemployment
Public Policy and Job Search Govt programs affecting unemployment • Govt employment agencies:disseminate info about job openings to better match workers & jobs. • Public job training programs:help workers displaced from declining industries get skills needed for jobs in growing industries. LECTURE 6 Unemployment
Unemployment insurance (UI) • UI pays part of a worker’s former wages for a limited time after losing his/her job. • UI increases search unemployment, because it reduces • the opportunity cost of being unemployed • the urgency of finding work • Rate of job finding, f • Studies: The longer a worker is eligible for UI, the longer the duration of the average spell of unemployment. LECTURE 6 Unemployment
Benefits of UI • By allowing workers more time to search, UI may lead to better matches between jobs and workers, which would lead to greater productivity and higher incomes. LECTURE 6 Unemployment
Unemployment Benefits • Provided in developed countries • Eligibility excludes new entrants to the labor force and those giving up job voluntarily • Raises aggregate demand and contributes toward early recovery of an economy from recession
Why is there Unemployment? • Two reasons why f < 1: 1.job search 2.wage rigidity The natural rate of unemployment: DONE Next LECTURE 6 Unemployment
Supply Real wage Unemployment Rigid real wage Demand Labor Amount of labor hired Amount of labor willing to work Unemployment from Real Wage Rigidity & Structural Unemployment If real wage is stuck above its equilibrium level, then there aren’t enough jobs to go around. LECTURE 6 Unemployment
Unemployment from Real Wage Rigidity If real wage is stuck above its equilibrium level, then there aren’t enough jobs to go around. Then, firms must ration the scarce jobs among workers. Structural unemployment: The unemployment resulting from real wage rigidity and job rationing. LECTURE 6 Unemployment
Reasons for Wage Rigidity 1. Minimum wage laws 2. Labor unions 3. Efficiency wages LECTURE 6 Unemployment
The Minimum Wage • The minimum wage may exceed the equilibrium wage of unskilled workers, especially teenagers. • Studies: a 10% increase in min. wage reduces teen employment by 1-3% • Tendency for firms to substitute towards illegal workers (who are not bound by the min. wage) • But, the minimum wage cannot explain the majority of the natural rate of unemployment, as most workers’ wages are well above the minimum wage. LECTURE 6 Unemployment
Minimum Wage Law • It is enacted in almost every country so that forces cannot drive it down too low. • When wages are pushed up to the level of w*, unemployment to the extent bc is created, since supply exceeds demand. • In addition, there is also unemployment to the extent of cd, which is due to people looking for better jobs
Labor Unions • Unions exercise monopoly power to secure higher wages for their members (collective bargaining). • When the union wage exceeds the equilibrium wage, unemployment results. • Insiders: Employed union workers whose interest is to keep wages high. • Outsiders: Unemployed non-union workers who would be willing to work for lower wages, so there would be enough jobs for them. LECTURE 6 Unemployment
Collective Bargaining by Labor Union • Every country legalizes labor union activity to prevent excessive exploitation of labor by the employer • Experiences have shown that if politicization of labor union can be avoided and labor unions abide by the rules of the game then union activities can contribute towards congenial industrial relations

3. Efficiency Wage Theory • Idea: higher wages increase worker productivity by: • Attracting higher quality job applicants (“Adverse Selection” problem) • Increasing worker effort, reducing “shirking” (“Moral Hazard” problem) • Reducing turnover, which is costly to firms • Improving health of workers: better nutrition & productivity (in developing countries) • Firms willingly pay above-equilibrium wages to raise productivity, causing structural unemployment. LECTURE 6 Unemployment
Other Types of Unemployment and Macroeconomic Policies LECTURE 6 Unemployment
Cyclical Unemployment • Y* represents full employment output level • Sometimes national output falls due to a fall in demand, this is called recession. Labor demand declines, additional unemployment to the extent of ee* • This is called cyclical unemployment
Stabilization Policy • Developed countries can stabilize cyclical unemployment through expansionary monetary or fiscal policies • Expansionary monetary policy increases credit supply which raises aggregate demand. An expansionary fiscal policy on the other hand reduces taxes
Disguised Unemployment • Developing countries are generally not close to the full employment level. Here, unemployment does not occur due to periodic demand shortfall. These countries, like Bangladesh suffer from disguised unemployment.
Structural Unemployment • Large scale unemployment caused by low productive capacity • Unlike cyclical unemployment, structural is of long-term nature • Reduction of structural unemployment requires expansion of productive capacity which takes time
Seasonal Unemployment • Periodic Unemployment • Agricultural workers suffer unemployment during agricultural lean seasons. Workers in developed countries can however easily switch skills to meet varying labor demands • Can also be countered through government intervention
