In this paper, I estimate the fiscal impact of immigrants on the German pension insurance (PI) and unemployment insurance (UI) systems when return migration is an endogenous choice. For this purpose, I develop a dynamic stochastic model of joint return migration and saving decisions that...

We investigate the interaction between labour and credit market imperfections for equilibrium unemployment in the presence of profit sharing. In a partial equilibrium with exogenous outside options increased bargaining power of banks has adverse employment effects. In a general equilibrium with...

We study the implications of product market competition and investment for price setting, wage bargaining and thereby for equilibrium unemployment in an economy with product and labour market imperfections. We show that intensified product market competition will reduce equilibrium unemployment,...

Firing frictions and renegotiation costs affect worker and firm preferences for rigid wages versus individualized Nash bargaining in a standard model of equilibrium unemployment, in which workers vary by observable skill. Rigid wages permit savings on renegotiation costs and prevent workers from...

Does a country?s level of unemployment have an impact on the long-run growth rate? Incorporating unemployment into a generalised augmented Solow-type growth model, yields some answers to this question. In particular, we show that the impact of unemployment on productivity growth heavily depends...

This paper theoretically investigates the impact of European integration on employment by developing a new-keynesian model where fiscal policy effectively reduces firms? market power. Stronger product market competition is shown to reduce the marginal ability of governments to improve employment...

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 evaluate the effects of international outsourcing and labor taxation on wage formation and equilibrium unemployment in dual labor markets. Outsourcing promotes wage dispersion between the high-skilled and low-skilled workers. Higher domestic low-skilled wage tax, higher payroll tax and lower...

Standard models of equilibrium unemployment assume exogenous labour market institutions and flexible wage determination. This paper models wage rigidity and collective bargaining endogenously, when workers differ by observable skill and may adopt either individualized or collective wage...
