Relational contracts when employed as a tool of economic policy create mutual dependency between State and enterprises. This bluntly contradicts the principles of „Ordnungspolitik" as the key policy device to ensure efficiency on the microeconomic level and growth on the macroeconomic level....

Governments may draft contracts with market agents for allocating subsidies and pursuing specific policy goals. Contract enforcement via binding commitments is difficult, however, when exogenous (environmental) and endogenous (behavioural) risks interact. Analyzing the old debt compromise in...

I build a dynamic stochastic general equilibrium model with search and matching frictions in the labor market and analyze the optimal monetary policy response to an outward shift in the Beveridge curve. The results cover several cases depending on the reason for the shift. If the shift is due to...

This paper analyzes the effects of short-time work (i.e., government subsidized working time reductions) on unemployment and output fluctuations. The central question is whether the rule based component (i.e., the existence of the institution short-time work) and the discretionary component...

We analyze the implications of changes in the trend growth rate for optimal monetary policy in the presence of search and matching unemployment. We show that trend growth in itself does not generate a trade-off for the monetary authority, but that it interacts importantly with the inefficiencies...

We study the design of optimal monetary policy in a New Keynesian model with labor turnover costs in which wages are set according to a right to manage bargaining where the firms' counterpart is given by currently employed workers. Our model captures well the salient features of European labor...

The paper analyzes the effects of disembodied technological progress on steady state hours worked in the workhorse New-Keynesian model, which features a neoclassical labor market, and its extension that allows for equilibrium unemployment. Both versions of the model are shown to imply a positive...

We develop a dynamic general equilibrium trade model with comparative advantage, heterogeneous firms, heterogeneous workers and endogenous firm entry to study wage inequality during the adjustment after trade liberalization. We find that trade liberalization increases wage inequality both in the...

Many labor market models use both idiosyncratic productivity and a vacancy free entry condition. This paper shows that these two features combined generate an equilibrium comovement between matches on the one hand and unemployment and vacancies on the other hand, which is observationally...

The secular shift in labor demand from unskilled to skilled labor is explained within a model that is solved numerically. There are three branches producing a basic good, a differentiated luxury good, and an intermediate service. Production is more skill-intensive in the luxury good and the...
