We investigate how group boundaries, and the economic environment surrounding groups, affect altruistic cooperation and punishment behavior. Our study uses experiments conducted with 525 officers in the Swiss Army, and exploits random assignment to platoons. We find that, without competition...

This paper studies the vulnerability of the pivotal mechanism with respect to manipulation by groups. In a lab experiment, groups decide on the implementation of various alternatives, some of which imply opposite interests for the two subgroups. We investigate the occurrence of tacit and...

We examine the strategic sophistication of adolescents, aged 10 to 17 years, in experimental normal-form games. Besides making choices, subjects have to state their first- and second-order beliefs. We find that choices are more often a best reply to beliefs if any player has a dominant strategy...

In an experiment, we study risk-taking of cohabitating student couples, finding that couples' decisions are closer to risk-neutrality than single partners' decisions. This finding is similar to earlier experiments with randomly assigned groups, corroborating external validity of earlier results.

This paper develops a theoretical model of dynamic decision-making of a monetary policy committee with heterogeneous members. It investigates the optimal transparency, and the optimal way of transmitting information of committees, by analysing the effects different communication strategies have...

This paper presents an experimental study that compares the ability of human groups to escape the tragedy of the commons through institutional change or communication. Teams of five players are placed in a dynamic CPR environment with inefficient institutional settings. The results clearly show...

How many people should decide about monetary policy? In this paper, we take an empirical perspective on this issue, analyzing the relationship between the number of monetary policy decisionmakers and monetary policy outcomes. Using a new data set that characterizes Monetary Policy Committees...

Recent scholarship on the impact of fiscal institutions on budgeting outcomes in Latin American and Caribbean (LAC) countries indicates that political institutions impact the level of budget discipline. BuiIding upon this previous research, we argue that the principle problem that must be...

While monetary policy decisions are mainly taken by Committees (as is the case for the ECB, or for the Federal Reserve), the literature largely stands on the …ction of a single central banker, be it (or not) a conservative one. The purpose here is to consider explicitly the plural dimension of...

This paper presents an experimental study on the ability of human groups to escape the tragedy of the commons through institutional change. It shows that the groups identify institutional change as a means of resolving social dilemmas and are ready to apply it even if the change requires an...
