We analyse an oligopoly model in which differentiated criminal organizations compete on criminal activities and engage in corruption to avoid punishment. When law enforcers are sufficiently well-paid, difficult to bribe and corruption detection highly probable, we show that increasing policing...

This paper analyses the interplay between social structure and information exchange in two competing activities, crime and labour. We consider a dynamic model in which individuals belong to mutually exclusive two-person groups, referred to as dyads. There are multiple equilibria. If jobs are...

We present a simple model to analyse law enforcement problems in transition economies. Law enforcement implies coordination problems and multiplicity of equilibria due to a law abidance and a fiscal externality. We analyse two institutional mechanisms for solving the coordination problem. A...

The aim of this paper is to show that both location and stereotypical racial beliefs matter for explaining the high criminality rate among blacks in cities. In our model, blacks and whites are identical in all respects. However, if, for not economic but extrinsic reasons, everybody (including...

This paper investigates the effect of corruption on competition in government procurement auctions. Our assumption is that the bureaucrat (i.e. the agent that administers the market), if corrupt, may provide a favour in exchange for a bribe. The favour we consider in most of our analysis is the...

This paper analyzes the long-term sickness absences in Sweden using a longitudinal database that contains all compensated sickness spells for 2,789 persons during 1986-1991. Given the political focus on the improved collaboration between the individual, physician, employer, and social insurance...

This paper analyzes the effects of being on part-time sick leave compared to full-time sick leave on the probability of recovering (i.e., returning to work with full recovery of lost work capacity). Using a discrete choice one-factor model, we estimate mean treatment parameters and...

The question addressed in this paper is whether sickness history affects annual earnings and hourly wages in Sweden. If poor health makes people less productive, we expect to find a negative effect of previous health history on hourly wages. If, instead, poor health reduces people´s working...

In this paper, we analyze exits from long-term sickness spells in Sweden. Using spell data for more than 2500 people, aged 20-64 years during 1986-1991, and who had at least one sickness spell of at least 60 days during 1986-1989, the aim is to analyze the transition to different states, i.e.,...

The number of disability exits has been increasing in recent years, raising questions both about the well being of affected individuals, and about how to finance the related disability pensions. Using a longitudinal database owned by the Swedish National Social Insurance Board, this study...
