This paper presents a model of nations where agents vote on the optimal level of public pending. Larger nations benefit from increasing returns in the provision of public goods, but bear the costs of greater cultural heterogeneity. This tradeoff induces agents' preferences over different...

This paper uses a linguistic tree, describing the genealogical relationship between all 6,912 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...

This paper theoretically analyzes and empirically investigates the importance of local interaction between individuals of different linguistic groups for the provision of public goods at the national level. Depending on whether local interaction mitigates or reinforces antagonism towards other...

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...

Culture has played a pivotal role in human evolution. Yet, the ability of social scientists to study culture is limited by the currently available measurement instruments. Scholars of culture must regularly choose between scalable but sparse survey-based methods or restricted but rich...

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...

This paper analyzes the importance of local interaction between individuals of different linguistic groups for the provision of public goods at the national level. The micro-founded conceptual framework we develop predicts that a country's public goods (i) decrease in its overall linguistic...

This paper analyzes whether the propensity to secede by subnational regions responds mostly to differences in income per capita or to distinct identities. We explore this question in a quantitative political economy model where people's willingness to finance a public good depends on their...
