During the hundred-year period from about 1320 to about 1420, the Florentine woollen cloth industry underwent two closely connected crises. The first crisis was the consequence, direct and indirect, of the ravages of warfare and falling population, afflicting the entire Mediterranean basin and...

This (revised) study seeks to examine the rise, expansion, and ultimate decline of the Italian wool-based textile industries over a period of six centuries (from ca. 1100 to ca. 1730). An international trade model combining transaction costs and comparative advantage is employed to explain the...

This is a substantially revised version of an earlier Working Paper (posted in 2002, with a different title), based on much new data and other information. It re-examines Earl Hamilton’s famous 1929 thesis on ‘Profit Inflation’ and the ‘birth of modern industrial capitalism’: namely,...

This paper investigates both aggregate and distributional impacts of the trade integration of China, India, and Central and Eastern Europe in a quantitative multi-country multi-sector model, comparing outcomes with and without factor market frictions. Under perfect within-country factor...

This paper presents a model of international trade that features heterogeneous firms, relative endowment differences across countries, and consumer taste for variety. The paper demonstrates that firm reactions to trade liberalization generate endogenous Ricardian productivity responses at the...

The paper explores the determinants of industry location across interwar Poland. After more than 120 years of political and economic separation, Poland was reunified at the end of 1918. In consequence, its industry faced massive structural changes: the removal of internal tariff barriers and...

Although economists have long been aware of Jensen's inequality, many econometric applications have neglected an important implication of it: the standard practice of interpreting the parameters of log-linearized models estimated by ordinary least squares as elasticities can be highly misleading...

This paper derives a micro-founded gravity equation based on a translog demand system that allows for flexible substitution patterns across goods. In contrast to the standard CES-based gravity equation, translog gravity generates an endogenous trade cost elasticity. Trade is more sensitive to...

An important feature of the U.S. labor market is that, even after controlling for measurable differences in education and experience, the average wage of women with children is 89 percent of the average wage of women without children. This ``family gap\\\" in wages accounts for almost half the...
