What has driven trade booms and trade busts in the past and present? We derive a micro-founded measure of trade frictions from leading trade theories and use it to gauge the importance of bilateral trade costs in determining international trade flows. We construct a new balanced sample of...

Conventional wisdom in economic history suggests that conflict between countries can be enormously disruptive of economic activity, especially international trade. Yet nothing is known empirically about these effects in large samples. We study the effects of war on bilateral trade for almost all...

Long-run cross-country price data exhibit a puzzle. Today, richer countries exhibit higher price levels than poorer countries, a stylized fact usually attributed to the Balassa- Samuelson effect. But looking back fifty years, this effect virtually disappears from the data. What is often assumed...

This paper derives original series of average years of schooling in the United States 1870-1930, which take into account the impact of mass migrations on the US educational level. We reconstruct the foreign-born US population by age and by country of origin, while combining data on the flow of...

This paper examines the responses of Indigenous nations and European companies to new trading opportunities: Cree nations and the Hudson's Bay Company (HBC), and Khoe nations and the Dutch East India Company (VOC). This case study is important because of the disparate outcomes: within a few...

In this study we evaluate the role that Mediterranean Medieval trade with Africa and the Middle-East still plays today in Italian politics by shaping the attitudes towards migrants of individuals that live close to Medieval ports. Trade connections between Medieval ports and Muslim Africa and...

For a very long time, the areas available for continuous long-distance trade were limited to territories the size of Braudel's Mediterranée (1949). Whatever the commercial organizations (merchants in the Roman or the Fatimid Empires, the Hanseatic League, the Florentine Companies), their trade...

What determines trade patterns? Habit persistence in consumer tastes and learning-by-doing in production imply that history and culture matter. Deriving a dynamic gravity equation from a simple model, it is shown that cultural similarity is a product of history, so that trade patterns are a...

The paper focuses on meetings as an over-utilized, but often under-structured tool for managerial effectiveness and efficiency. The authors present four different meeting types, more precisely termed team facilitations, as commonly used in aviation by flight crews: Brainstorming, Briefing,...
