While most papers on team decision-making find that teams behave more selfishly, less trustingly and less altruistically than individuals, Cason and Mui (1997) report that teams are more altruistic than individuals in a dictator game. Using a within-subjects design we re-examine group...

In laboratory experiments we explore the effects of communication and group decision making on investment behavior and on subjects' proneness to behavioral biases. Most importantly, we show that communication and group decision making does not impact subjects' overall proneness to biases like...

We present experimental evidence for decision settings where public good providers compete for endogenous donations offered by outside donors. Donors receive benefits from public good provision but cannot provide the good themselves. The performance of three competition mechanisms is examined in...

This study presents novel evidence showing that group payments distributed proportional to effort are as effective as payments targeted to individuals in increasing public good provision. The decision setting includes donors who make transfer payments to public good providers. The institutions...

This paper investigates whether distributional conflicts become more likely when groups are involved in the fight. We present results from a laboratory experiment in which two parties can appropriate resources via a contest or, alternatively, take an outside option. Keeping monetary gains...

The provision of public goods often benefits a larger group than those who actively provide the public good. In an experimental setting, this paper addresses institutional arrangements between subjects who can provide a public good (insiders) and subjects who benefit from the public good but...

We examine behavior in one-shot appropriation games with deterministic and probabilistic degradation externalities, where the marginal net benefit from appropriation is endogenous, dependent on individuals' expectations of group appropriation. The experimental design involves a menu of games...

We study the influence of gender and gender pairing on economic decision making in an experimental two-person bargaining game where the other party's gender is known to both actors. We find that (1) gender per se has no significant effect on behavior, whereas (2) gender pairing systematically...

In this paper we present results from experimental asset markets and simulations with traders who receive asymmetric information about the fundamental value of an asset. In the experimental markets with repetition insiders outperform the market and uninformed computerized random traders...

We examine bidding behaviour of individuals and teams in an experimental auction resembling UMTS-license auctions. Even though in reality teams were largely involved in those auctions, experimental studies on bidding in auctions have so far relied on individual bidders. Our results show that...
