The divorce rate in Norway has increased sharply since the 1960s, and today Norway ranks among the countries with the highest divorce rates in Europe. In this paper we estimate determinants of marital instabilities.

The increasing number of disability pensioners may put a strain on the welfare state. In this paper, we try to assess the effect of financial incentives on disability entrance. A sample of Norwegians on long-term sick leave at the beginning of 1989 is examined as of the end of 1989 and the exit...

This paper analyses the scope for collusive behaviour within the context of an international duopoly supergame in which both firms and monopoly labour unions interact strategically.

We look at a country that has chosen to fix its exchange rate. The country can choose to tie its currency to alternative countries. The question is which one it will be optimal to choose. Three factors are considered: Trade share, real exchange rate variation and real shocks. A large trade share...

We provide necessary condition for Pareto optimum in economies where tastes or technologies may be nonconvex, nonsmooth, and affected by externalities. Firms can pursue own objectives, much like the consumers. Infinite-dimensional commodity spaces are accomodated. Public goods and material...

Emission of uniformly dispersed greenhouse gases in construed here as a cooperative production game, featuring side-payments, quata exchange, uncertainty, and multi-period planning. Stochastic programming offers good instruments to analyze such games. Absent efficient markets for emissions, such...

Motivated by non-cooperative games we study repeated interaction among non-communicating agents, each dealing with his block of variables, each moving merely on the basis of his marginal payoff and its most recent change.

Motivated by economic examples the authors study equation solving undertaken in parallel by several non-communicating agents, each dealing with his own block of variables. The process is akin to Newton's method in using derivative information. It does, however, proceed without matrix inversion...

We present a new subgame perfect equilibrium in an infinitely repeated game, which has Basu's triadic model as the stage game. The payoff for the laborer is the same as in Basu's model. The equilibrium is more robust than the solution in Naqvi and Wemhoner in the sense that the equilibrium does...

Unregulated monopolies produce too low quantity levels. When workers participate in decision making, there will be a tendency for the firm to select even lower employment levels than will be chosen by pure profit-maximising firms. On the other hand, the employed workers' incentives to work long...
