The paper estimates how wages respond to changes in regional unemployment using detailed Swedish micro data. The study is set in an economy with close to complete union coverage where real wages have grown continuously in all parts of the wage distribution for the past 15 years, and where the...

In August 2010 the Costa Rican government implemented a comprehensive program to increase compliance with legal minimum wages, the Campaign for Minimum Wages. To evaluate the impact of the Campaign, we use a regression discontinuity approach, which compares what happened to workers who before...

A striking feature of the past few decades has been the development of wage-determination models that assume that labour markets are imperfectly competitive. This paper discusses two such models (trade unions and oligopsony), although there are many more. It also asks if imperfectly competitive...

This paper examines the interaction between minimum wage legislation and tax evasion by employed labor. I develop a model in which firms and workers may agree to report less than the true amount of earnings to the fiscal authorities. I show that introducing a minimum wage creates a spike in the...

The minimum wage rate has been introduced in many countries as a means of alleviating the poverty of the working poor. This paper shows, however, that an imperfectly enforced minimum wage rate causes small firms to face an upward-sloping labor supply schedule. Since this turns these firms into...

We revisit the development of monthly wages in Germany between 2000 and 2017. While wage inequality strongly increased during the first years of this period, it recently returned to its initial level, raising the question what the role of the German minimum wage introduction for this reversal...

Contrary to widespread belief, we show that low-pay workers might not generally prefer that the minimum wage rate be increased to a level where the labor demand is unitary elastic. Rather, there exists a critical value of elasticity of labor demand such that increases in the minimum wage rate...

We estimate the effects of the introduction and subsequent increases of a substantial minimum wage in Germany's main construction industry on wage and employment growth rates. Using a regional dataset constructed from individual employment histories, we exploit the spatial dimension and border...

For two different regulatory standards, we examine the optimal minimum wage in a competitive labour market when the government is uncertain about supply and demand. Solutions are related to underlying supply and demand conditions, and the extent of uncertainty and of rationing efficiency. We...

A model of on-the-job training in the presence of a minimum wage is presented. This predicts that the minimum wage will have a negative effect on a worker's subsequent wage growth when the labour market is competitive but a U-shaped effect when it is not competitive. This prediction is then...
