We study contributions and punishment in a linear public goods game, where group members differ in the sources of their endowments. We compare homogenous groups in which subjects are exogenously assigned to the same endowments with heterogeneous groups in which half of the group members invest...

We devise a new experimental game by nesting a voluntary contributions mechanism in a broader spectrum of incentive schemes. With it, we study tensions between egalitarianism, equity concerns, self-interest, and the need for incentives. In a 2x2 design, subjects either vote on or exogenously...

We study a fundamental conflict in economic decision-making, the trade-off between equality, equity and incentives, in a new experimental game that nests a voluntary contributions mechanism in a broader spectrum of incentive schemes. In a 2×2 design, we let subjects either vote on or...

This discussion paper has led to a publication in <A href="http://www.springerlink.com/content/r6x36x128621t040/">'Journal of Risk and Uncertainty'</A>, 44(1), 45-72.<P>This study attempts to combine two traditional fields in microeconomics: individual decision making under risk and decision making in an interpersonal context. The influence of social comparison on...</p></a>

Since 1950s, most African nations have gained independence from their colonial powers. Fortunately, independence has brought many changes to these nations and these include multi-party democratic government and western education systems. Unfortunately, the Africa’s economy is the least...

Teams often suffer from a free rider problem with respect to individual contributions. That putting teams into competition with each other can mitigate this problem is an important recent insight. However, we know little about how inequality in endowment between teams might influence this...

In this experiment I study a novel three-player ultimatum game in which two proposers with unequal amounts of money simultaneously submit offers to one responder, who may accept at most one offer. I compare the predictions of inequity aversion, advantage seeking, and self-interest. Unlike...

We compare inequality aversion in individuals and teams by means of both within- and between-subject experimental designs, and we investigate how teams aggregate individual preferences. We find that team decisions reveal less inequality aversion than individual initial proposals in team...
