We study the consequences of imperfect competition in a macro model with only one imperfection; that of labor market competition. Otherwise the model is ‘clean’; agents are optimizers, prices are endogenous, and expectations are rational. We show that, although imperfect competition in...

This paper analyzes the welfare implications of regulating some but not all monopolistic industries of an economy (i.e., marginal regulation). It is shown that marginal regulation decreases welfare if a large fraction of all industries are monopolistic. Furthermore, the paper shows that the...

This paper analyses the impact of tax reforms that decrease income tax progression in an equilibrium search model with wage bargaining and endogenous individual working time. The working time is either bargained together with the hourly wage (case 1) or determined solely by workers after...

This paper analyses systematic monetary policy in a dynamic stochastic menu cost model. The main assumptions are that price setters have to pay small adjustment costs in order to equalize actual and optimal prices whereas the central bank can do so costlessly (by adjusting the money supply) but...

Most workers are only partially insured against unemployment. One reason is that high unemployment compensation creates a free rider problem when monitoring of job search behavior is limited; people who do not seek employment (non-workers) may nevertheless collect unemployment compensation. We...

This paper discusses aspects of active labour market policy implemented in Denmark after 1993. In particular, we consider effort commitment as a mean to provide work incentives for the jobless, which was introduced as an alternative to reducing unemployment benefits. Our main points are (1) that...

New Keynesian literature assumes symmetric industrial structure when analysing explanations of money non-neutrality. This paper analyses the impact of modifying this assumption by allowing for a mixed industrial structure; some industries are characterized by monopolistic competition, others by...

This paper develops a dynamic general equilibrium model combining standard theory of labour unions and capital accumulation. Comparison of results stemming from labour unions and perfect competition in the labour market shows that predictions regarding growth rates during transition are...

In the future, a ban of pay-per-view broadcasting will arise on certain events included on national lists in each EU country as put forward in the new "Television Without Frontiers" Directive from the 16th of April, 1997. This paper analyses theoretically the consequences of such ban when the...
