Labor market institutions, via their effect on the wage structure, affect the investment decisions of firms in labor markets with frictions. This observation helps explain rising wage inequality in the US, but a relatively stable wage structure in Europe in the 1980s. These different trends are...

Nach dem »Mainzer Modell« erhalten Bezieher von niedrigen Erwerbseinkommen bei Neuaufnahme einer sozialversicherungspflichtigen Beschäftigung Zuschüsse zu ihren Sozialversicherungsbeiträgen. Nach Meinung von Dr. Hans-Peter Klös und Holger Schäfer, Institut der deutschen Wirtschaft Köln,...

We study the implications of product and labor market imperfections for equilibrium unemployment under both exogenous and endogenous capital intensity. With endogenous capital intensity, stronger labor market imperfections always increase equilibrium unemployment. The relationship between the...

We study the various consequences of and the incentives for outsourcing. We argue that the wage elasticity of labour demand increases as a function of the share of outsourcing, which is a result consistent with existing empirical research. Furthermore, we show that a production mode with a...

We evaluate the effects of outsourcing and wage solidarity on wage formation and equilibrium unemployment in a heterogeneous labour market, where wages are determined by a monopoly labour union. We find that outsourcing promotes the wage dispersion between the high-skilled and low-skilled...

We analyze the following questions associated with outsourcing and profit sharing under imperfect labour markets. How does strategic outsourcing influence wage formation, profit sharing and employee effort when firms commit to optimal profit sharing before wage formation or decide for profit...

We analyze the questions associated with flexible outsourcing both with committed and flexible profit sharing under imperfect domestic labour markets. How does profit sharing influence flexible outsourcing? What is the relationship between outsourcing cost, profit sharing and equilibrium...

We introduce search and matching unemployment into a model of trade with differentiated goods and heterogeneous firms. Countries may differ with respect to size, geographical location, and labor market institutions. Contrary to the literature, our single-sector perspective pays special attention...

This paper constructs a theory of the coexistence of fixed-term and permanent employment contracts in an environment with ex-ante identical workers and employers. Workers under fixed-term contracts can be dismissed at no cost while permanent employees enjoy labor protection. In a labor market...

This paper shows that increases in the minimum wage rate can have ambiguous effects on the working hours and welfare of employed workers in competitive labor markets. The reason is that employers may not comply with the minimum wage legislation and instead pay a lower subminimum wage rate. If...
