The two fund separation property of the elliptical distributions is extended to the skew-elliptical and by adding a number of funds equalling the rank of the skewness matrix. Some elements of the generalization to singular extended skew-elliptical distributions are covered.

The pseudo-isotropic multivariate distributions are shown to satisfy Ross’ stochastic dominance criterion for two-fund monetary separation. The classical case of separation under abence of risk-free investment opportunity, admits a few particular generalizations to k-fund separation for...

We propose a general framework to unambiguously compare distributions functions in an economically interpretable way. Our framework provides complete ranking of any set of distributions and money metric interpretation of the social welfare level of a dominating distribution as compared to a...

We consider an industry with firms that produce a final good emitting pollution to different degree as a side effect. Pollution is regulated by a tradable quota system where some quotas may have been allocated at the outset, i.e. before the quota market is opened. We study how volatility in...

We consider the effects of vertical integration on the performance of long-term and spot markets when spot prices are uncertain and agents are risk averse. We find that vertical integration impairs market performance by increasing the gap between contract and (expected) spot prices. This holds...

We explore the efficacy of price and quantity controls as environmental policy instruments in a stochastic setting in which agents are risk averse. We demonstrate that the assumption of risk aversion may improve the performance of a tax relative to that of a system of tradable quotas, and that...

Norway is often referred to as the prime example of a country that has achieved high growth and low income inequality despite its vast natural resources. This contrasts sharply with many other resource abundant countries, which raises the questions why Norway has succeeded while many other...

This paper discusses aspects of a framework for modeling labor supply where the notion of job choice is fundamental. In this framework, workers are assumed to have preferences over latent job opportunities belonging to worker-specific choice sets from which they choose their preferred job. The...

In this paper we discuss a general framework for analyzing labor supply behavior in the presence of complicated budget- and quantity constraints of which some are unobserved. The individual’s labor supply decision is viewed as a choice from a set of discrete alternatives (jobs). These jobs are...

This paper analyzes the properties of a particular sectoral labor supply model developed and estimated in Dagsvik and Strøm (2006). In this model, agents have preferences over sectors and latent job attributes. Moreover, the model allows for a representation of the individual choice sets of...
