Departures from self-interest in economic experiments have recently inspired models of "social preferences". We design a range of simple experimental games that test these theories more directly than existing experiments. Our experiments show that subjects are more concerned with increasing...

We study games played between groups of players, where a given group decides which strategy it will play through a vote by its members. When groups consist of two voting players, our games can also be interpreted as network-formation games. In experiments on Stag Hunt games, we find that that...

We study how two dimensions of market conditions affect behaviour in experimental gift-exchange markets with repeated interaction. First, we consider the impact of competitive imbalance, by varying whether there is an excess supply of "firms" or an excess supply of "workers" in the market....

Do people care about intentions - even when good intentions do not produce good results? In our experiments we find that rates of punishment and reward react strongly to intentions (the wage a firm decides to pay) and more modestly to distributional outcomes (the higher or lower wage actually...

It is traditional in experimental games to allow participants to choose only actions or possibly communicate intended play. In sequential two-person games, we require first movers to express a preference between responder choices. We find that responder behavior differs substantially according...

We study worker and firm behavior in an environment where worker effort could depend on co-workers’ wages. Theoretically, we show that an increase in workers’ ‘concerns’ with coworkers’ wages should lead profit-maximizing firms to compress wages under quite general conditions. However,...

We investigate how donating worker earnings for voluntary extra work, a form of corporate social responsibility, affects worker behavior. In our experiment, participants performed a realeffort task. Subjects were asked to enter real data (from an unrelated experiment) for 60 minutes and were...

In this paper, we describe a series of laboratory experiments that implement specific examples of a general network structure. Specifically, actions are either strategic substitutes or strategic complements, and participants have either complete or incomplete information about the structure of a...

In this paper, we describe a series of laboratory experiments that implement specific examples of a more general network structure and we examine equilibrium selection. Specifically, actions are either strategic substitutes or strategic complements, and participants have either complete or...
