We present a model where each of two players chooses between remuneration based on either private or team effort. Although at least one of the players has the equilibrium strategy to choose private remuneration, we frequently observe both players to choose team remuneration in a series of...

We examine voluntary private contributions to reduce the probability of a public loss in the experimental economics laboratory. In several treatments, we examine how loss probability, initial wealth and ambiguity affect the contribution level. We observe that, in contrast to the risk-neutral...

In this experimental study we examine behavior relating to voluntary contributions to reduce expected losses associated, for example, with the occurrence of natural disasters or major industrial accidents. We ask subjects to allocate tokens between a private investment and a public investment....

In a series of experimental effort games each of two players may choose between remuneration based on either private or team effort. Although at least one of the players has the subgame perfect equilibrium strategy to choose remuneration based on private effort, we frequently observe team...

In this paper, we investigate in a controlled laboratory experiment physician behavior in the case of payment heterogeneity. In the experiment, each physician provides medical care to patients whose treatments are paid for either under fee-for-service (FFS) or capitation (CAP). We observe that...
