Promises are prevalent in many competitive environments, but promise keeping is often difficult to observe. Do promises still offer an opportunity to honor future obligations, if promise keeping is unobservable? Focusing on campaign promises, we study the value of transparency. We showhow...

From marketing and advertising to political campaigning and court proceedings, contending parties expend resources to persuade an audience of the correctness of their view. We examine how the probability of persuading the audience depends on the resources expended by the parties, so that...

We introduce a framework of electoral competition in which voters have general preferences over candidates' characteristics and policies. Candidates' immutable characteristics (such as gender, race or previously committed policy positions) are exogenously differentiated, while candidates can...

Interest groups are introduced in a spatial model of electoral competition between two political parties. We show that, by coordinating voting behavior, these interest groups increase the winning set, which is defined as the set of policy platforms for the challenger that will defeat the...

This article analyses the dynamics of electoral promises, building on an electoral competition model with endogenous policies. It extends the Grossman-Helpman (1994) model [Grossman G., Helpman E. [1994], Protection for sale, American Economic Review, 84, 4, 833-850] to include sanctions from...

This paper studies how political competition can lead candidates to strategically increase the salience of specific issues, in order to influence voting decisions of marginal groups, with non trivial consequences for turnout rates. In my setup issues differ in their divisiveness, to be defined...

Previous research has established that good-looking political candidates win more votes. We extend this line of research by examining differences between parties on the left and on the right of the political spectrum. Our study combines data on personal votes in real elections with a web survey...

The European higher education landscape has become increasingly integrated causing competition among universities that is no longer bound to national borders. In view of this development, the present paper investigates the relative efficiency of 450 European universities between 2011 and 2014....

Charitable donations provide positive externalities and can potentially be increased with an understanding of donor preferences. We obtain a uniquely comprehensive characterization of donation motives using an experiment that varies treatments between and within subject. Donations are increasing...

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...
