Study Notes
The Labour Market
- The labour market is central to understanding the medium-run adjustment of prices and wages, affecting output.
- Unemployment rate is the ratio of the unemployed to the labor force.
- An active labor market has many separations and hires.
- In a sclerotic labor market, there are few separations and hires, and a stagnant unemployment pool.
- Separations include quits and layoffs.
- The average duration of unemployment is the length of time people spend unemployed.
Unemployment Rate
- Unemployment rate can show either an active or sclerotic labor market.
- Discouraged workers aren't actively seeking work but would accept it if offered, and are counted as "out of the labor force."
- Economists sometimes focus on the employment rate (ratio of employment to the population) instead of the unemployment rate.
Wage Determination
- Wages are sometimes set by collective bargaining (between unions and firms).
- Slightly more than 10% of U.S. workers' wages are set this way.
- Higher skill jobs are more likely to have bargaining between employers and individual employees.
- Collective bargaining is significant in Japan and most European countries.
- Workers are usually paid above their reservation wage (the wage at which they are indifferent between working or being unemployed).
- Wages depend on labor market conditions; lower unemployment rates correlate with higher wages.
- Workers' bargaining power depends on the cost of firms finding new workers and how easily workers can find new jobs elsewhere.
- Efficiency wage theory links worker productivity to wages.
- Firms may pay above the reservation wage to reduce worker turnover and boost productivity.
Wage Determination
- The aggregate nominal wage (W) depends on the expected price level (Pe), unemployment rate (u), and a catch-all variable (z).
- W = Pe F(u, z) (-, +).
- Workers and firms focus on real wages (W/P), not nominal wages.
- Nominal wages depend on the expected price level, not the actual price level.
Wage Determination
- An increase in the unemployment rate typically leads to lower wages. This can either weaken workers' bargaining power or permit firms to pay lower wages.
- Factors (z) affecting wage determination include unemployment insurance and employment protection laws.
Price Determination
- Firm prices depend on costs and production function (Y = AN).
- Y is output, N is employment, and A is labor productivity (output per worker).
- Marginal cost of production is equal to the wage (W).
- Firms often set prices using a markup (m) over cost.
- P = (1 + m)W.
Wage Determination
- If the wage (W) depends on the actual price level (P) rather than the expected price level (Pe), then W/P = F(u, z).
- Higher the unemployment rate, lower the real wage chosen by wage setters.
- Price-setting relation: W/P = 1 / (1 + m)
Price Determination
- Dividing the price determination equation by the nominal wage gives the price-setting relation: W/P = 1 / (1 + m).
- Price-setting decisions directly affect the real wage paid by firms.
The Equilibrium Unemployment Rate
- Equilibrium unemployment rate (un) is derived by equating the wage-setting and price-setting relations.
- un depends on z and m.
- It's also known as the natural rate or structural rate of unemployment.
The Natural Rate of Unemployment
- The natural rate of unemployment is the rate at which the real wage chosen in the wage-setting relation equals the real wage implied by the price-setting relation.
Comparative Statics
- An increase in unemployment benefits raises the natural rate of unemployment.
- The wage-setting curve shifts right/up.
- An increase in the markup also increases the natural rate of unemployment.
- The price-setting curve shifts down.
Short-Term and Medium-Term
- In the short run, price levels may differ from expected price levels, leading to unemployment rates different from the natural rate, or output levels different from the natural level.
- Output tends to return to its natural level in the medium run due to the consistency of expectations.
