Abstract

We study equilibria in static entry games with single-dimensional private information. Our framework embeds many models commonly used in applied work, allowing for firm heterogeneity and selective entry. We introduce the notion of strength, which summarizes a firm's ability to endure competition. In environments of applied interest, an equilibrium in which entry strategies are ordered according to the firms' strengths always exists. We call this equilibrium herculean. We derive simple and testable sufficient conditions guaranteeing equilibrium uniqueness and, consequently, a unique counterfactual prediction.

Journal of Economic History
Abstract

We use data from marriage records in Murcia, Spain, in the eighteenth century to study the role of women in social mobility in the pre-modern era. Our measure of social standing is identification as a don or doña, an honorific denoting high, though not necessarily noble, status. We show that this measure, which is acquired over the lifecycle, shows gendered transmission patterns. In particular, same-sex transmission is stronger than opposite-sex, for both sons and daughters. The relative transmission from fathers versus mothers varies over the lifecycle, and grandparents may affect the status of their grandchildren.

Economic History Review
Abstract

For centuries, irrigation communities in south-eastern Spain were socially stable and economically efficient. In this article, we show how these self-governing institutions persisted by resolving conflicts over scarce resources with flexible punishment for water theft. We argue that variable penalties for violating irrigation rules provided social insurance to farmers during droughts. We develop a dynamic model in which judges trade off crime deterrence and social insurance, and test its predictions using a novel dataset on water theft in the self-governed irrigation community of Mula, Spain, from 1851 to 1948. For the same offence, we show that recidivists were punished more harshly than first-time offenders. When the defendant was wealthy, as indicated by the honorific title don, or the victim was poor, judgements were stricter.
