Sampling poses an interesting problem in markets with experience goods. Free samples reveal product quality and help consumers to make informed purchase decisions (promotional effect). However, sampling may also induce consumers to substitute purchases with free consumption (displacement...

This paper presents a game theoretic analysis of the generalized second-price auction that the company Overture operated in 2004 to sell sponsored search listings on search engines. We construct a model that embodies few prior assumptions about parameters, and we present results that indicate...

In this paper we consider a two-stage duopoly game where firms first decide whether to invest in advertising and then compete in prices. Advertising has two effects: a market enlargement for both firms and a predatory gain for the investing firm only. Both symmetric and asymmetric equilibria may...

Hundreds of studies have failed to establish the effects of decentralisation on a number of important policy goals. This paper examines the cases of Bolivia and Colombia to explore decentralisation’s effects on government responsiveness and poverty-orientation. I first summarize economic data...

The determinants of government responsiveness to its citizens is a key issue in political economy. Here we develop a model based on the solution of political agency problems. Having a more informed an politically active electorate strengthens incentives for governments to be responsive. This...

The welfare economic method for analyzing the case for government intervention is often critized for ignoring the political determination of policies. The standard method of accounting for this critique studies the case for intervention under the constraint that the level of the instrument in...

This paper explores the relationship between ethnic diversity and local school funding in Kenyan primary schools. The empirical results paint a picture of pervasive local collective action problems in ethnically diverse Kenyan primary schools. Local ethnic diversity is robustly associated with...

I examine decentralization through the lens of the local dynamics that it unleashes. The national effects of decentralization are simply the sum of its local-level effects. Hence to understand decentralization we must first understand how local government works. This paper proposes a theory of...

Hundreds of studies have failed to establish the effects of decentralization on a number of important policy goals. This paper examines the remarkable case of Bolivia to explore decentralization's effects on government responsiveness and poverty-orientation. I first summarize econometric results...

A unifying theme in the literature on organizations such as public bureaucracies and private non-profits is the importance of missions, as opposed to profit, as an organizational goal. Such mission-oriented organizations are frequently staffed by motivated agents who subscribe to the mission....
