Does an income tax harm economic efficiency more the more progressive it is? Public economics provides a strong case for a definite ‘yes’. But at least three forces may pull in the other direction. First, low-wage workers may on average have more elastic labour supply schedules than...

The concept of ‘fully permissible sets’ is defined by an algorithm that eliminates strategy subsets. It is characterized as choice sets when there is common certain belief of the event that each player prefer one strategy to another if and only if the former weakly dominates the latter on...

In a model with a traded and a non-traded sector and centralised wage setting within each sector, it is shown that the monetary regime affects the trade-off between consumer real wages and employment and profits. Thus, the monetary regime affects the outcome of the wage negotiations, and...

We develop a framework for analyzing national income accounting using a revealed welfare approach that is sufficiently general to cover, e.g., both the standard discounted utilitarian and maximin criteria as special cases. We show that the basic welfare properties of comprehensive national...

As crime becomes increasingly widespread it may be optimal not to lower but to increase the standard of evidence. Even though a higher standard of evidence results in a lower expected penalty for all levels of crime, it increases the expected penalty for high levels of crime relative to the...

We seek to explain why TV advertising is dominated by a few product categories. We apply a model of the TV industry that encompasses both the product markets and the market for TV viewers to discuss who will advertise on TV. Under the assumption that viewers dislike advertising, entailing a...

We study an international climate agreement that assigns emission quotas to each participating country. Unlike the simplest models in the literature, we assume that abatement costs are affected by R&D activities undertaken in all firms in all countries, i.e. abatement technologies are...

Most wage-contracting models with rational expectations fail to replicate the persistence in inflation observed in the data. We argue that coordination problems and multiple equilibria are the keys to explaining inflation persistence. We develop a wage-contracting model in which workers are...

A dynamic macroeconomic model is used to analyze the interaction between economic growth, labor demand and crime. Due to endogenous crime, the model exhibits increasing returns to aggregate capital at certain development levels. At other development levels, however, there are decreasing returns...

We provide a new explanation for why firms pay for general training in a competitive labor market. If firms are unable to tailor individual wages to ability, for informational or institutional reasons, they will pay for general training in order to attract better quality workers. The market...
