This paper examines how violence influences the political preferences of an aggrieved constituency that is purportedly represented by militant factions. Using longitudinal public opinion poll micro data of the Palestinian population linked to data on fatalities from the Second Intifada, we find...

The burgeoning literature on the use of sanctions to support the provision of public goods has largely neglected the use of formal or centralized sanctions. We let subjects playing a linear public goods game vote on the parameters of a formal sanction scheme capable of either resolving or...

In a developing country, terrorists recruit and allocate their capital, skilled labor, and unskilled labor between domestic and foreign targets. Domestic targets require less skilled labor than foreign targets. Under various strategic scenarios, we show how countermeasures against the different...

Military spending, fatalities, and the destruction of capital, all of which are immediately felt and are often large, are the most overt costs of war. They are also relatively short-lived. But the costs of war borne by combatants and their caretakers, which includes families, communities, and...

We conduct a repeated VCM (voluntary contribution mechanism) experiment using the strategy method and compare contribution behavior in a partner and a stranger matching in both a cold and a hot setting, where the latter differs from the former by allowing participants to revise their strategies...

Mission-driven nonprofit organizations compete for donations through fundraising activities. Such competition can lead to inefficient outcomes, if nonprofits impose externalities on each others' output. This paper studies the sustainability of fundraising coordination agreements, using a...

We examine determinants of immigration requirements in a public goods game experiment with endogenous groups. Initially, the game consists of in-group players who enjoy an existing public good and out-group players who may subsequently enter the group. Motivated by different current migration...

We conduct a controlled field experiment in 52 communities in rural Bolivia to investigate the effect that local authorities have on voluntary public good provision. In our study, community members pool resources to provide environmental education material for local schools. We find that...

Experimental studies have shown that sanctions effectively deter free riding within groups. However, the over-use of costly punishment may actually harm overall welfare. A main reason for over-punishment is that free-riders generate negative emotions that likely favor excessive punishments. In...
