In this paper we introduce the notion of stability threshold that quantifies the minimal returns to size sufficient to prevent credible secession threats by regions of the country. Severity of internal tension has been linked to degree of polarization of citizens' preferences and...

This paper presents a model of nation formation in which culturally heterogeneous agents vote on the optimal level of public spending. Larger nations benefit from increasing returns in the provision of public goods, but bear the costs of greater cultural heterogeneity. This tradeoff induces...

In this note we introduce a general class of games where the payoff of every player are affected by her intrinsic taste for available strategic choices; intensity of her dyadic social interactions of with others in the peer group; and conformity effect. We show, that if the dyadic social...

In this paper, we lay the first building blocks of a positive theory of nation formation where national choices consist of the size and location of a public good. Individuals differ both in income and in their preferences for the public good location. Public expenditures are financed either by a...

We study majority voting over a bidimensional policy space when the voters' type space is either uni- or bidimensional. We show that a Condorcet winner fails to generically exist even with a unidimensional type space. We then study two voting procedures widely used in the literature. The...

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...

The paper considers a model of federation with two heterogeneous regions that try to attract the capital by competing in capital income taxes and public investment that enhance the productivity of capital. Regions' choices determine allocation of capital across the regions and their revenues...

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,...

Extensive multilingualism is one of the most important and fundamental principles of the European Union. However, a large number of official languages (currently 23) hinders communication and imposes substantial financial and legal costs. We address the merits of multilingualism and formulate an...

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...
