This note deals with Cournot type oligopolies in which the market clearing price occasionally may be non-unique. A Stackelberg leading producer is present. Given that setting we explore continuity properties of the followers' reaction and provide sufficient conditions for existence of equilibrium.

In this paper we evaluate a Norwegian vocational rehabilitation program by comparing employment outcomes of trainees and nonparticipants using nonexperimental data. A matching estimator based on the propensity score is used to calculate the training effect for different subgroups of the sample.

This note deals with on-line computatin of learning of Pareto optimal insurance contracts. We account for the fact that the loss distribution often is unknown, unavailable, or intractable. Alternatively, the contracting parties could be inexperienced. In both cases losses must be simulated of...

This study analyses early retirement pathways for Norwegian male and female workers, applying a multinomial logit model to a data set covering more than 10500 employees, ages 56-61, in 1989. The aim is to analyse the transistion to different destinations, i.e. disability pension, unemployement...

Owners of stochastic assets can pool their endowments to smoothen and insure individual payoffs across outcomes and time. We explore, in such a setting, how contingent shadow prices on aggregate resources can be used for three purposes: first, to design mutual contracts for risk averse agents;...

Environmental problems are tied to the use of exhaustible resources. A resource tax extracts rents from the resource owning countries, whitout creating significant incentives for consumers to reduce their resource consumption. The placement of the tax burden on resource owners affects the...

Consider an auction in which potential bidders must sink an entry investment before learning their values. Suppose the auction designer can make the bidders learn their value before entry. Such early information will induce screening of high-value bidders, and it will give rise to information...

We analyse the question of optimal taxation in a dual economy, when the government is concerned about the distribution of labour incom. Income inequality is caused by the presence of sunk capital investments, which creates a 'good jobs' sector due to the capture of quasi-rents by trade unions.

We formulate a simple static equilibrium model for the electricity market taking account of both Green Certificates and CO2-emission permits. The objective is to investigate the relationship between these markets under the existence of upper and lower price-bounds on the Green certificates, both...

We believe that group-lending institutions have incentives to include members outside the target-group of poor households. This implies a methodological problem that is rarely taken into account in empirical studies. We apply a general household survey, and find some evidence of non-poor...
