A Continuous Dilemma

Abstract: We study prisoners' dilemmas played in continuous time with flow payoffs accumulated over 60 seconds. In most cases, the median rate of mutual cooperation is about 90 percent. Control sessions with repeated matchings over eight subperiods achieve less than half as much cooperation, and cooperation rates approach zero in one-shot sessions. In follow-up sessions with a variable number of subperiods, cooperation rates increase nearly linearly as the grid size decreases, and, with one-second subperiods, they appro… Show more

“…First, one could consider changes in the value of T that are in an even smaller neighborhood of the threshold value that differentiates the SH from the PD to examine whether such smaller changes might give precedents even more weight. In addition, one might explore the role of precedent across similar games played in continuous time; Friedman and Oprea (2012), for instance, report varying but very high cooperation rates for different parameterizations of the Prisoner's Dilemma game played by subjects in continuous time. It would be of interest to consider play in continuous (or near continuous) time across similar classes of games including the Stag Hunt and Prisoner's Dilemma games or the Battle of the Sexes and Chicken games.…”

“…Another problem is the affecting of the numerous factors that are not in a close proximity with the basic characteristics of the evaluated object, such as the inflation rate, economic situation, etc. It's remarkable that these kinds of cost evaluation method's shortcomings are described in the well-known works by such scientific authorities as M. Friedman [15], L. I. Abalkin [16], G. Odum [17] et al…”

“…It seems to be noteworthy the position of M. Friedman [15] suggesting that economic theory can be exact and objective as much as natural sciences. The problems of objectivity and reliability of measurements and estimates in economy were figuratively described by A.…”

“…The first one corresponds to continuous-time experiments, the second to "timing experiments", with a special emphasis on the experimental bank-runs literature. Continuous time experiments started years ago, with Friedman and Cheung (2009) and Morgan and Brunnermeier (2010) (whose working papers appeared around 2003/04), but it has not been until recently that this experimental technique has taken off with Oprea et al (2009) and Anderson et al (2010) looking into strategic investment decisions, Oprea et al (2011) studying the evolutionary equilibrium of the hawk and dove game, Friedman and Oprea (2012) experimenting with the effects of response delay in a repeated prisoners dilemma game, and Rabanal (2012) looking at mortgage default timing. While none of these papers directly address any of the questions of our paper, they are a good reference for the methodological design of our experiment.…”
