We study pure redistribution as a device to increase cooperation and efficiency in the provision of public goods. Experimental subjects play a two-stage game. The first stage is the standard linear public goods game. In the second stage, subjects can redistribute payoffs among other subjects in...

Short term unemployment in the Danish labor market is closely related to temporary layoffs. This paper presents some facts about the structure of unemployment and the ways of financing unemployment benefit (UB) in Denmark and Sweden. Next, a simplified version of the "Feldstein-model" of...

A two-country macro model is used to analyze domestic and international effects of the imposition of tariffs. The results on the international transmission of tariffs are then utilized in setting up a tariff game under a fixed exchange rate. In this tariff game, the non-cooperative Nash and...

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...

Is variation in empirical mortality across populations consistent with a hypothesis of selec-tion? To examine this proposition an extended frailty mortality model is put forward; incor-porating biological frailty; a common non-parametric hazard, joint for men and women, rep-resenting endogenous...

In this paper we consider a model of group formation where group of individuals may have different feasible sets. We focus on two polar cases, increasing returns, when the set of feasible alternatives increases if a new member joins thegroup, and decreasing returns, when a new member has an...

Much of the literature on industry evolution has found firm dynamics to be an important source of sector-level productivity growth. In this paper, we ask whether the delineation of entry and exit firms matters in assessing the impact of firm turnover. Using detailed firm level data from Vietnam,...

In recent years, there has been increased interest in setting up guidelines for carrying out cost-effectiveness analysis of medical interventions, and some such guidelines have indeed been established. In the paper, we present a model of information retrievement and use in which we can study the...

Many key macro-economic and ?nancial variables are characterised by permanent changes in unconditional volatility. In this paper we analyse vector autoregressions with non-stationary (unconditional) volatility of a very general form, which includes single and multiple volatility breaks as...
