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...

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 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...

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...

Suppose that an opportunity arises for two countries to negotiate a free trade agreement (FTA). Will an FTA between these countries be politically viable? If so, what form will it take? We address these questions using a political economy framework that emphasizes the interaction between...
