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 ethnolinguistic conflict on redistribution. The analysis focuses on the conflict arising between “peripheral” minority groups and a dominant “center”. We propose an index of linguistic conflict that (i) encompasses both diversity and polarization, and (ii) accounts for the distance between lanuguages. Our results(More)
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 within-group variation in culture trumps between-group variation. Thus, in(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 Somnez (2001) and Bogomolnaia and Jackson (2002). We apply their results to study the original Gamson game and o er extensions both to a multi-dimensional characteristics space and to an in(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 presents a model of nation formation in which culturally heterogeneous agents vote on the optimal level of public spending. Larger nations beneÞt from increasing returns in the provision of public goods, but bear the costs of greater cultural heterogeneity. This tradeoff induces agents’ preferences over different geographical conÞgurations, thus(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 develop a novel methodology to analyze intergenerational social mobility over long periods of time when the precise ancestors of the individual cannot be identi…ed. We base our approach on the incorporation of surnames in the analysis of social mobility, applying our methodology to assess the degree of intergenerational social mobility within two Spanish(More)
