We consider a model of political competition among two ideological parties who are uncertain about the distribution of voters. The distinguishing feature of the model is that parties can delegate electoral decisions to candidates by nomination. It is shown that if the credible platform...

In this paper we analyze the implementation of socially optimal mergers when the regulator is not informed about the parameters that determine social and private gains from potential mergers. We find that most of the standard tools in dominant strategy implementation, like the revelation...

We study the incentives to firms to create divisions once the vertical structure of an industry is taken into account. Downstream firms, those that must buy an essential input from upstream firms, may create divisions. Divisionalization reduces their bargaining power against upstream firms. This...

The optimal competition policy when licensing is an alternative to a merger, which has the intention of transferring a superior technology, and is derived in a differentiated goods duopoly, as in the cases of Cournot and Bertrand competition. We show that whenever both royalties and fixed fees...

The US Merger Guidelines consider that the anticompetitive effect of a horizontal merger is increasing in the initial market concentration and decreasing in the elasticity of demand. These ideas are studied in a setting where identical firms compete a la Cournot and marginal cost is constant....

We study managerial incentives in a model where managers take not only product market but also take-over decisions. We show that the optimal contract includes an incentive to increase the firm's sales, under both quantity and price competition. This result contrasts with the previous literature,...

We investigate the empirical relationship between ethnicity and culture, defined as a vector of traits reflecting norms, attitudes and preferences. Using surveys of individual values in 76 countries, we find that ethnic identity is a significant predictor of cultural values, yet that...

We consider a linguistically diversified society that has to select a set of official languages. We examine the notion of language disenfranchisement that is created when one or more languages fail to be included in the list of the official ones, implying that some individuals are denied full...

This paper investigates the effect of ethnolinguistic conflict on redistribution. The analysis focuses on the conflict arising between ‘peripheral’ minority groups and a dominant ‘centre’. We propose an index of linguistic conflict that (i) encompasses both diversity and polarization,...

In this paper we adopt the Selten-Pool model (1993) framework of language acquisition that is based on the notion of communicative benefits and learning costs. We consider a model with languages that serve as imperfect substitutes and show that under supermodularity of the communicative benefits...
