Money Is More Than Memory, Maria Bigoni, Gabriele Camera, Marco Casari Dec 2018

Money Is More Than Memory, Maria Bigoni, Gabriele Camera, Marco Casari

ESI Working Papers

Impersonal exchange is the hallmark of an advanced society and money is one key institution that supports it. Economic theory regards money as a crude arrangement for monitoring counterparts’ past conduct. If so, then a public record of past actions—or memory—should supersede the function performed by money. This intriguing theoretical postulate remains untested. In an experiment, we show that the suggested functional equivalence between money and memory does not translate into an empirical equivalence: money removed the incentives to free ride, while memory did not. Monetary systems performed a richer set of functions than just revealing past behaviors.


Centrality And Cooperation In Networks, Boris Van Leeuwen, Abhijit Ramalingam, David Rojo Arjona, Arthur Schram Sep 2018

Centrality And Cooperation In Networks, Boris Van Leeuwen, Abhijit Ramalingam, David Rojo Arjona, Arthur Schram

Economics Faculty Articles and Research

We investigate the effects of centrality on cooperation in groups. Players with centrality keep a group together by having a pivotal position in a network. In some of our experimental treatments, players can vote to exclude others and prevent them from further participation in the group. We find that, in the presence of exclusion, central players contribute significantly less than others, and that this is tolerated by those others. Because of this tolerance, teams with centrality manage to maintain high levels of cooperation.


Sex Differences In Political Leadership In An Egalitarian Society, Christopher Von Rueden, Sarah Alami, Hillard Kaplan, Michael Gurven Mar 2018

Sex Differences In Political Leadership In An Egalitarian Society, Christopher Von Rueden, Sarah Alami, Hillard Kaplan, Michael Gurven

ESI Publications

We test the contribution of sex differences in physical formidability, education, and cooperation to the acquisition of political leadership in a small-scale society. Among forager-farmers from the Bolivian Amazon, we find that men are more likely to exercise different forms of political leadership, including verbal influence during community meetings, coordination of community projects, and dispute resolution. We show that these differences in leadership are not due to gender per se but are associated with men’s greater number of cooperation partners, greater access to schooling, and greater body size and physical strength. Men’s advantage in cooperation partner number is ...


Indefinitely Repeated Contests: An Experimental Study, Philip Brookins, Dmitry Ryvkin, Andrew Smyth Feb 2018

Indefinitely Repeated Contests: An Experimental Study, Philip Brookins, Dmitry Ryvkin, Andrew Smyth

ESI Working Papers

We experimentally explore indefinitely repeated contests. Theory predicts more cooperation, in the form of lower expenditures, in indefinitely repeated contests with a longer expected time horizon, yet our data do not support this prediction. Theory also predicts more cooperation in indefinitely repeated contests compared to finitely repeated contests of the same expected length, but we find no significant difference empirically. When controlling for risk and gender, we actually find significantly higher long-run expenditure in some indefinite contests relative to finite contests. Finally, theory predicts no difference in cooperation across indefinitely repeated winner-take-all and proportional-prize contests. We find significantly less cooperation ...
