This research explores the biocultural origins of human capital formation. It presents the first evidence that moderate fecundity and thus predisposition towards investment in child quality was conducive for long-run reproductive success within the human species. Using an extensive genealogical...

We exploit regional variation in suitability for cultivating potatoes, together with time variation arising from their introduction to the Old World from the Americas, to estimate the impact of potatoes on Old World population and urbanization. Our results show that the introduction of the...

This Paper argues that shareholder activism can be considered as similar to the adoption of increasing returns-to-scale technology by financial institutions. I start from this mechanism to build a model designed to assess the long-run consequences of shareholder pressure. I then use this model...

We document key facts about marriage and divorce, comparing trends through the past 150 years and outcomes across demographic groups and countries. While divorce rates have risen over the past 150 years, they have been falling for the past quarter century. Marriage rates have also been falling,...

Technological change was unskilled-labor-biased during the early Industrial Revolution, but is skill-biased today. This is not embedded in extant unified growth models. We develop a model which can endogenously account for these facts, where factor bias reflects profit maximizing decisions by...

This paper studies the role of internal migration in income convergence across regions in Japan. Neoclassical theory predicts that migration should have been an important source of convergence, but regression results suggest otherwise. The paper investigates the possibility that this discrepancy...

Technological change was unskilled-labour-biased during the early Industrial Revolution of the late eighteenth and early nineteenth centuries, but is skill-biased today. This fact is not embedded in extant unified growth models. We develop a model of the transition to sustained economic growth...

Using data on name distributions in 95 French departments observed from 1946 to 2002, we investigate spatial and social mechanisms behind the transmission of parental preferences. Drawing inspiration from recent work on social interactions, we develop a simple discrete choice model that predicts...

The purpose of this paper is to link the propensity for innovative activity to cluster spatially to the stage of the industry life cycle. The theory of knowledge spillovers, based on the knowledge production function for innovative activity, suggests that geographic proximity matters most in...
