Unemployment and the Labour Market - Key Concepts

Recap of Labour Market Fundamentals

In an ideal labour market, supply and demand for labour equate perfectly, leading to an equilibrium where unemployment is absent. However, this ideal scenario does not exist in reality due to various imperfections in the labour market.

Causes of Unemployment
  1. Wage Levels: When wages are set above market equilibrium, the quantity of labour supplied exceeds the quantity demanded. This leads to unemployment because there are more workers than available jobs.
Reasons for Labour Market Imperfection
  1. Minimum Wages: Mandatory minimum wages above the equilibrium can cause unemployment as businesses can't afford to hire everyone wanting work.
  2. Unions and Collective Bargaining: Unions can negotiate higher wages than the market would normally allow, leading to reduced demand for labour and increased unemployment.
  3. Efficiency Wages: Firms may pay higher than equilibrium wages to boost productivity, which may inadvertently lead to unemployment if these wages discourage hiring.
The Economics of Unions
  • Unions negotiate wages that are typically above those of non-unionized workers. However, this can lead to inefficiencies in the labour market and some workers benefiting at the expense of others instead of a balanced outcome.
Theory of Efficiency Wages
  • Companies may benefit from paying workers above-average wages through improved health, reduced turnover, increased effort, and higher quality of applicants. However, this can create a surplus of workers seeking jobs, thus contributing to unemployment.
Natural Rate of Unemployment
  • The natural rate of unemployment refers to a long-term average level of employment that doesn't go away and includes frictional and structural unemployment. Cyclical unemployment reflects short-term fluctuations tied to the economy's business cycle.
Frictional and Hysteresis Unemployment
  • Frictional unemployment occurs when individuals are temporarily out of work while transitioning between jobs. This is a normal part of job searching and arises from changes in labor demand across sectors.
  • Hysteresis indicates that prolonged unemployment makes it harder for individuals to find work, thus contributing to persistent unemployment levels.
Summary

Labour market imperfections, such as minimum wage laws and union influence, can result in unemployment by raising wages above equilibrium. Efficiency wages may improve worker productivity but can also perpetuate unemployment. The combination of natural, cyclical, and frictional unemployment contributes to the overall dynamics of the labour market, indicating that some level of unemployment is inherent in a changing economy.
