a r t i c l e i n f o This paper uses a linguistic tree, describing the genealogical relationship between all 6912 world languages, to compute measures of diversity at different levels of linguistic aggregation. By doing so, we let the data inform us on which linguistic cleavages are most relevant for a range of political economy outcomes, rather than(More)
This paper proposes a new method to measure ethnolinguistic diversity and offers new results linking such diversity with a range of political economy outcomes — civil conflict, redistribution, economic growth and the provision of public goods. We use linguistic trees, describing the genealogical relationship between the entire set of 6, 912 world languages,(More)
This paper investigates the effect of linguistic diversity on redistribution in a broad cross-section of countries. We use the notion of " linguistic distances " and show that the commonly used fractionalization index, which ignores linguistic distances, yields insignificant results. However, once distances between languages are accounted for, linguistic(More)
This note adds one celebrated coalition formation game due to Gamson (1961) in the list of applications of the theory of hedonic games explored by Banerjee, Konishi and S • omnez (2001) and Bogomolnaia and Jackson (2002). We apply their results to study the original Gamson game and ooer extensions both to a multi-dimensional characteristics space and to an(More)
We propose a new method to assess the merit of any set of scientific papers in a given field based on the citations they receive. Given a field and a citation impact indicator, such as the mean citation or the [Formula: see text]-index, the merit of a given set of [Formula: see text] articles is identified with the probability that a randomly drawn set of(More)
This paper attempts to detect the existence of links in consumption preferences between generations. Preferences for consumption goods may be determined by the preferences of parents (vertical transmission) and/or by preferences arising from the environment (horizontal transmission). We propose an indirect methodology to overcome the lack of data on(More)
We investigate the empirical relationship between ethnicity and culture, de…ned as a vector of traits re ‡ecting norms, attitudes and preferences. Using surveys of individual values in 76 countries, we …nd that ethnic identity is a signi…cant predictor of cultural values, yet that within-group variation in culture trumps between-group variation. Thus, in(More)
We analyze existence of equilibrium in a one-dimensional model of endogenous party platforms and more than two parties. The platforms proposed by parties depend on their membership composition. The policy implemented is a function of the different proposals and the vote distribution among such proposals. It is shown that if voters are sincere there is(More)
We analyze existence of divergent equilibria in a model of en-dogenous party platforms with stochastic membership. The parties proposals depend on their membership, while the membership depends both on the proposals of the parties and the unobserved idiosyncratic preferences of citizens over parties. It is shown that when citizens view the parties as(More)
