Originally propounded by the 16th-century scholars of the University of Salamanca, the concept of purchasing power parity (PPP) was revived in the interwar period in the context of the debate concerning the appropriate level at which to re-establish international exchange rate parities. Broadly...

Great attention is now being paid to global imbalances, the growing U.S. current account deficit financed by growing surpluses in the rest of the world. How can the issue be understood in a more historical perspective? We seek a meaningful comparison between the two eras of globalization:...

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 50 years, or more, this effect virtually disappears from the data. What is...

According to the Washington Consensus, developing countries’ growth would benefit from a reduction in tariffs and other barriers to trade. But a backlash against this view now suggests that trade policies have little or no impact on growth. If "getting policies right" is wrong or infeasible,...

How will free trade affect monetary policy and exchange rate regime choices in the Americas? While the European Union illustrates how the creation of an integrated market in goods and services can enhance monetary cooperation and integration, it is not clear that Europe’s experience translates...

Technological change was unskilled-labor-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...

The PPP puzzle is based on empirical evidence that international price differences for individual goods (LOOP) or baskets of goods (PPP) appear highly persistent or even non-stationary. The present consensus is these price differences have a half-life that is of the order of five years at best,...

What determines sovereign risk? We study the London bondmarket from the 1870s to the 1930s. Our findings support conventional wisdom concerning the low credibility of the interwar gold standard. Before 1914 gold standard adherence effectively signalled credibility and shaved 40 to 60 basis...

An empirical tradition in international trade seeks to establish whether the predictions of factor abundance theory match present-day data. In the analysis of goods trade and factor endowments, mildly encouraging results were found by Leamer et al. But ever since the appearance of Leontief's...
