We present clean evidence of a direct social context effect on behavior in a laboratory experiment: the gender composition of the room significantly alters the risk decisions of subjects even when the actions or presence of others are neither payoff nor information relevant. Our design is such...

We examine gender differences in bargaining outcomes in a highly competitive and commonly used market: the taxi market in Lima, Peru. Examining the entire path of negotiation we find that men face higher initial prices and rejection rates. These differentials are consistent with both statistical...

Catastrophic events can dramatically alter existing social and economic relationships. The consequences can be long-lasting and give rise to heterogeneity of behavior across populations. We investigate the impact of a large negative shock on altruism, trust and reciprocity in 30 small Honduran...

This paper addresses three questions: (1) When deciding on whether to reward or punish someone, how does how you think others expect you to behave affect your decision? (2) Does it depend upon whether others expect you to reward them vs. punish them? (3) What is the interpretation of such a...

In games with multiple, Pareto-rankable equilibria and repeated play, does a history of playing an inefficient equilibrium make it harder for the players to reach the efficient equilibrium? In other words, can people Ôget stuckÕ in bad equilibria? Previous studies have found support for this,...

The patent system makes organized markets in patents with transparent prices possible. Such prices are here investigated as "signals" for inventors and innovators alike of valuable "technology areas," in an experimental study. They inform decisions of specialized "firms" on allocation of...

The question of how prices on patents rights should be determined in impersonal exchanges is examined in a laboratory environment. Dynamic gains from such organized trade with public prices are recorded. The experiment introduces a competitive market with impersonal exchange mechanisms and...

We are well familiar with the economic analysis of a patent system in terms of a temporary monopoly on products, benefitting from marginal process inventions, formulated under conditions of certain future demands. This article develops an experimental and dynamic microeconomic model useful for...

The work of Friedrich Von Hayek contains several testable predictions about the nature of market processes. Vernon Smith termed the most important one the "Hayek hypothesis:" equilibrium prices and the gains from trade can be achieved in the presence of diffuse, decentralized information, and in...

Over 25% of the US population volunteers. Clary et al. (1998) devised a survey that identifies a volunteer's primary motive for volunteering. We investigate the effect of tailoring the communications that volunteers receive from their organizations (e.g., printed newsletters, update emails) to...
