Most professional economists believe that economists in general are more selfish than other persons and that this greater selfishness is due to economics education. This paper offers empirical evidence against this widely held belief. Using a unique data set about giving behavior in connection...

Under appropriate assumptions (private values and uniform punishments), the Nash equilibria of a Bayesian repeated game without discounting are payoff-equivalent to tractable, completely revealing, equilibria and can be achieved as interim cooperative solutions of the initial Bayesian game. This...

In some important multi-player situations, such as efforts to supply a global public good, players can choose the game they want to play. In this paper we conduct an experimental test of the decision to choose between a “tipping” game, in which every player wants to contribute to the public...

The issue of internal security has become increasingly complex over the past decades. As there is an increasing overlap between private and public provision of security, the question of how to allocate responsibility for security between the public sphere (state) and the private sphere has...

We experimentally study the impact of framing effects in a repeated sequential social dilemma game. Our between-subjects design consists of two group level ("Wall Street" vs. "Community") and two individual level ("First (Second) Movers" vs. "Leaders (Followers)") frames. We find that average...

We consider a model where agents differ in their ‘types’ which determines their voluntary contribution towards a public good. We analyze what the equilibrium composition of groups are under centralized and centralized choice. We show that there exists a top-down sorting equilibrium i.e. an...

This study shows the uniqueness of Nash equilibrium in the model of multiple voluntarily supplied public goods with potential contributors possessing different Cobb-Douglas preferences. This study provides a sufficient condition for uniqueness using graph theory. This sufficient condition allows...

We report experimental findings on the role of charitable promises in bargaining settings. We vary the enforceability of such promises within variants of ultimatum games where the proposer suggest a split between himself, the responder and a char-itable donation. By reneging on initial pledges,...

This paper investigates how the heterogenous incomes and preferences of potential donors affect the timing of contribution decisions when it is endogenously determined by contributors themselves. More specifically, we use a simple setting with two donors, Cobb-Douglas preferences, and complete...

Traditional economic models of vaccination behavior simply assume that agents free-ride on the vaccination decisions of others. We provide three different models of private provision of a public good, such as a joint production model and a conjectural variation model, to explain how a positive...
