Piecewise deterministic control problems are problems involving stochastic disturbance of a special type. In certain situations, in an otherwise deterministic control system, it may happen that the state jumps at certain stochastic points of time. Examples are sudden oil finds, or sudden...

The performance of local tax offices of Norway is studied over a three year period applying Data Envelopment Efficiency analysis and a Malmquist productivity index. The estimates are biascorrected using a bootstrap approach recently developed for DEA models. The results show that bias correction...

In recent years, the OECD has measured the structural rate of unemployment by an indicator called the Non-Accelerating Wage Rate of Unemployment. The NAWRU-indicator is an important element in the policy analysis of the OECD. The rise in the estimated NAWRUs is also taken as evidence that Nordic...

We present some theoretical results which simplifies the estimation of linear models with multiple high-dimensional fixed effects. In particular, we show how to sweep out multiple fixed effects from the normal equations, in analogy with the common within-groups estimator

Most nations spend a considerable part of their gross domestic product (GDP) on defense. However, no previous study has addressed the productivity and efficiency of the core area of the armed forces, operational units, using Data Envelopment Analysis (DEA). Introducing a model for the production...

The performance of local tax offices of Norway is studied over a three-year period using Data Envelopment Efficiency analysis and calculating Malmquist productivity indices. One input, labour, is used, and six output categories of the main service activities carried out by tax offices are...

There is a growing interest in morale as a potential substitute for sanctions, encouraged by exerimental evidence that people's morale affect their economic decisions. I show that while morale may be a substitute for sanctions for each citizen, it is not a substitute in the market. In a model...

The memo consists of six papers on a common theme: applying economic analysis to subjects at the time, 1972, considered non-economic. The first paper considers changes in preferences. The second considers strategies of a regime and its opposition. The third discusses collective decision making...

This paper studies the aggregate distribution of declared opinions and behavior when heterogeneous individuals make the trade-off between being true to their private opinions and conforming to an endogenous social norm. The model sheds light on how various punishment regimes induce conformity or...

This paper considers the role which selfish, moral and social incentives and pressures play in explaining the extent to which stated choices over pro-environment behaviours vary across individuals. The empirical context is choices over household waste contracts and recycling actions in Poland. A...
