We extend a model of wasteful state aid in Dewatripont and Seabright (2006, Journal of the European Economic Association 4, 513-522) by a supranational controlling authority. The model combines moral hazard and adverse selection to show that politicians fund wasteful projects to signal their...

Consider an agent (manager, artist, etc.) who has imperfect private information about his productivity. At the beginning of his career (period 1, short run"), the agent chooses among publicly observable actions that generate imperfect signals of his productivity. The actions can be ranked...

Open source projects produce goods or standards that do not allow for the appropriation of private returns by those who contribute to their production. In this paper we analyze why programmers will nevertheless invest their time and effort to code open source software. We argue that the...

In this paper, we consider a dynamic signaling model of an R&D market in which a researcher can choose either a safe project (exploitation) or a risky project (exploration) at each instance. We argue that there are substantial efficiency gains from rewarding minor innovations above their social...

Generally, Democrats do not increase military spending, and Republicans do not raise welfare payments. Mostly, ruling politicians stick to the manifesto of their party. The current paper provides a theoretical explanation for this phenomenon that does not assume politicians or voters to be...

This study investigates under what circumstances there exist a separating equilibrium in which competent leaders choose incompetent co-workers and incompetent leaders choose competent co-workers. The driving force for the competent leader is the insurance motive; if things go wrong he can blame...

This paper investigates how an office-motivated incumbent can use transparency enhancement on public spending to signal his budgetary management ability and win re-election. We show that, when the incumbent faces a popular challenger, transparency policy can be an effective signaling device. A...

This paper studies a contest in which players with unobservable types may form an alliance in a pre-stage of the game to join their forces and compete for a prize. We characterize the pure strategy equilibria of this game of incomplete information. We show that if the formation of an alliance is...

We present a model of persuasive signalling, where a privately-informed sender selects from a class of signals with different precision to persuade a receiver to take one of two actions. The sender's information could be either favourable or unfavourable. The receiver observes both the sender's...
