Several investors face an irreversible investment opportunity whose value V is governed by Brownian motion with upward drift and random expiration. The first investor i to seize the opportunity before expiration receives the current V less a privately known cost Ci; the other investors receive...

We study David Gale's (1963) economy using laboratory markets. Tatonnement theory predicts prices will diverge from an equitable interior equilibrium toward infinity or zero depending only on initial prices. The inequitable equilibria determined by these dynamics give all gains from exchange to...

We investigate the nature of continuous-time strategic interactions in public-goodsgames. In one set of treatments, four subjects make contribution decisions in continuous timewhile in another they make them only at discrete points of time. The effect of continuous timeis muted in public-goods...

We study prisoner’s dilemmas played in continuous time with flow payoffs over 60 seconds. In most cases, the median rate of mutual cooperation rises to 90% or more. Control sessions with 8-time repeated matchings achieve less than half as much cooperation, and cooperation rates...

ConG is software for conducting economic experiments in continuous and discrete time. It allows experimenters with limited programming experience to create a variety of strategic environments featuring rich visual feedback in continuous time and over continuous action spaces, as well as in...

We investigate the nature of continuous time strategic interaction in public-goods games. In one set of treatments, four subjects make contribution decisions in continuous time during a 10-min interval while in another they make them only at 10 discrete points of time during this interval. The...

We explore the stability of imitation in a 1200-period experimental Cournot game where subjects do not know the payoff function but see the output quantities and payoffs of each oligopolist after every period. In line with theoretical predictions and previous experimental findings, our...

An irreversible investment opportunity has value V governed by Brownian motion with upward drift and random expiration. Human subjects choose in continuous time when to invest. If she invests before expiration, the subject receives V−C : the final value V less a given avoidable cost C ....
