This paper evaluates direct and structural discrimination as a means of increasing efforts in the most widely studied contests. We establish that a designer who maximizes efforts subject to a balanced-budget constraint prefers dual discrimination, namely, change of the contestants' prize...

A body of literature suggests that ethnic heterogeneity limits economic growth. This paper provides microeconometric evidence on the direct effect of ethnic divisions on productivity. In team production at a plant in Kenya, an upstream worker supplies and distributes flowers to two downstream...

The paper presents experimental evidence on the impact of managers and their incentives on the behavior of group members in intergroup contests. I find that members follow the nonbinding investment recommendations of their group manager in particular if the managers payoff does not depend on the...

The Israeli-Palestinian conflict constitutes a prominent example of a long-lasting political conflict which has major consequences for the livelihoods of the people on both sides. The agricultural sectors of the Palestinian and Israeli economies are tightly connected. However, various security...

This study empirically investigates the impact of group characteristics and host country conditions on the duration and the ending of terrorist organizations and rebel groups. The empirical analysis relies on data for more than 600 armed groups from the Terrorist Organization Profiles, collected...

In this paper we look at motivation over time by setting up a dynamic contest model where winning the first contest yields an advantage in the second contest. The win advantage introduces an asymmetry into the competition that we find reduces the expected value to the contestants of being in the...

We present a model of price leadership on homogeneous product markets where the price leader is selected endogenously. The price leader sets and guarantees a sales price to which followers adjust according to their individual supply functions. The price leader clears the market by serving the...

We propose the minimum approval mechanism (MAM) for a standard linear public good environment with two players. Players simultaneously and privately choose their contributions to the public good in the first stage. In the second stage, they simultaneously decide whether to approve the other's...

We examine the consequences, of integrating large minorities into productivity-relevant majority ethno-linguistic norms, for distribution, ethnic conflict and crime. We develop a two-community model where such assimilation generates social gains by: (a) facilitating economic interaction, and (b)...

This paper adopts an instrumental variable approach to uncover the impact of variations in minimum temperature on emergence and severity of actual violence through the effect on food availability, captured by rice crops per capita. The link between increase in minimum temperature and rice crops...
