The Choquet integral is an integral part of recent advances in decision theory involving non-additive measures. In this article we present two new axiomatic characterizations of this functional.

An uncertain and not just risky situation may be modeled using so-called belief functions assigning lower probabilities to events, that is, to sets of possible outcomes. In this paper we introduce an axiom of consistency by which we extend the von Neumann-Morgenstern expected utility theory to...

The so-called Allais Paradox (Allais (1953)) has been interpreted as a violation of the independence axiom of Savage (1954). Considering the standard experiments performed this inference is questionable. Rather the paradoxical behavior represents evidence against the expected utility hypothesis...

Capacities (monotone, non-additive set functions) have been suggested to describe situations of uncertainty. We examine the question of how to define the product of two independent capacities. In particular, for the product of two belief functions (totally monotone capacities), there is a unique...

This paper uses a two-dimensional version of a standard common consequence experiment to test the intransitivity explanation of Allais-paradox-type violations of expected utility theory. We compare the common consequence effect of two choice problems differing only with respect to whether...

This paper studies two-stage bargaining in a simple general equilibrium model with a dual labour market. We analyse the case where agreements reached at the central level in the unionized sector extend beyond this sector, which seems to be a characteristic feature of continental European labour...

This paper studies skill-neutral technological changes in an economy where workers differ with respect to their abilities to acquire skills, implying increasing marginal costs of educating the work force. Our main result is that productivity slowdown and increasing wage dispersion can be...

Most workers are only partially insured against unemployment. One reason is that high unemployment compensation creates a free rider problem when monitoring of job search behavior is limited; people who do not seek employment (non-workers) may nevertheless collect unemployment compensation. We...

This paper discusses aspects of active labour market policy implemented in Denmark after 1993. In particular, we consider effort commitment as a mean to provide work incentives for the jobless, which was introduced as an alternative to reducing unemployment benefits. Our main points are (1) that...
