Insurance companies invest their wealth in financial markets. The wealth evolution strongly depends on the success of their investment strategies, but also on liquidity shocks which occur during unfavourable years, when indemnities to be paid to thenclients exceed collected premia. An investment strategy that does not take liquidity shocks into account, exposes insurance companies to…

We consider economies with additively separable utility functions and give conditions for the two-agents case under which the existencenof sunspot equilibria is equivalent to the occurrence of the transfer paradox.nThis equivalence enables us to show that sunspots cannot matter if the initial economy has a unique spot market equilibrium and there are only twoncommodities or if the…

In this study the effects of various types of rehabilitation programmes on labour market out-comes are estimated. A main feature of this study is that it jointly evaluates multiple treat-ments by nonparametric matching estimators. The study is based on a large sample of per-sons in western Sweden who are long-term sick and could participate in rehabilitation pro-grammes. Our results…

One important motive for deregulating social health insurance is to encourage product innovation. For the first time, the cost savings achieved by non-US managed care plans that are attributable to product innovation are estimated, using a novel approach. Panel data from a major Swiss health insurer permits to infer health status, which can be used to predict health care expenditure…

In the literature on optimal indemnity schedules, indemnities are usually restricted to be non-negative. Gollier (1987) shows that this constraint might well bind: insured could get higher expected utility if insurance contracts would allow payments from the insured to the insurer at some losses. However, due to the insurers’ cost function Gollier supposes, the optimal insurance…

A model of start-up finance with double moral hazard is proposed. Entrepreneurs have ideas and technical competence, but lack own resources as well as commercial experience. Venture capitalists (VCs) provide start-up finance and managerial support. Both types of agents thus jointly contribute to the firm's success, but neither type's effort is verifiable. We find that the…

"The 1-shot alpha-beauty contest is a non-equilibrium strategic game under bounded rationality conditions, while equilibrium is approached if the game is played iteratively sufficientlynmany times. Experimental data of the 1-shot setting of the 0-equilibrium game show a common pattern: The spectrum of announced numbers is a superposition of a skew backgroundndistribution and a…

We examine how globalization affects firms incentives to train workers. In our model, firms invest in productivity-enhancing worker training before Cournot competition takes place. When two separated product markets become integrated and are thus replaced with a market with greater demand and greater firm number, training by each firm increases provided the two countries are…

We examine the characteristics and relative strength of third-party sanctions in a series of experiments. We hypothesize that egalitarian distribution norms and cooperation norms apply in our experiments, and that third parties, whose economic payoff is unaffected by the norm violation, may be willing to enforce these norms although the enforcement is costly for them. Almost two-…
