In aggregative games, each player's payoff depends on her own actions and an aggregate of the actions of all the players (for example, sum, product or some moment of the distribution of actions). Many common games in industrial organization, political economy, public economics, and...

We analyse an oligopoly model in which differentiated criminal organizations compete on criminal activities and engage in corruption to avoid punishment. When law enforcers are sufficiently well-paid, difficult to bribe and corruption detection highly probable, we show that increasing policing...

A firm must decide whether to launch a new product. A launch implies considerable fixed costs, so the firm would like to assess downstream demand before it decides. We study under which conditions a potential buyer would be willing to reveal his willingness to pay under different pricing...

A student's future log-wage is given by the sum of a skill premium and a random personal ‘ability’ term. Students observe only a private, noisy signal of their ability, and universities can condition admission decisions on the results of noisy tests. We assume first that universities are...

Firms' incentives to form research joint ventures (RJVs) are analysed in an incomplete information framework when technological know-how is private information. Firms first decide on cooperation and information revelation and then compete for a patent. Provided that spillovers exist in the case...

Economic decisions such as occupational and entrepreneurial choices may violate true comparative advantage when economic agents are uncertain about which activity best matches their talents. If relative performance varies over the business cycle (for instance, if downturns affect...

We study a class of representation mechanisms, based on reports made by a random subset of agents, called representatives, in a collective choice problem with quasi-linear utilities. We do not assume the existence of a common prior probability describing the distribution of preference types. In...

We shed light on the function, properties and optimal size of austerity using the standard sovereign model augmented to include incomplete information about credit risk. Austerity is defined as the shortfall of consumption from the level desired by a country and supported by its repayment...

This paper shows that delegation of monetary policy to a weight-conservative central banker is optimal, although the government can also use an inflation contract, an employment target, an inflation target, or any combination of these, to control the central banker. The key feature of our model...
