Defensive innovations in developed countries can explain the empirical phenomenon that openness towards trade with less-developed countries does not necessarily induce a substantial increase in the wage differential and trade volumes. Building on step-by-step innovations as introduced by Aghion...

This paper is a necessary companion to the one entitled The West European Woollen Industries and their Struggles for International Markets, c.1000 - 1500. No one can properly comprehend that five-century history of international competition for textile markets, without some basic understanding...

This paper revisits, modifies, and combines elements of three major 'institutional' international-trade models, none of which has yet fully received the attention that it deserves, to provide a new explanation for the growth, decline, and then rebirth of internationally-oriented fairs in the...

The classical Heckscher-Ohlin-Mundell paradigm states that trade and capital mobility are substitutes, in the sense that trade integration reduces the incentives for capital to flow to capital-scarce countries. In this paper we show that in a world with heterogeneous financial development, the...

In this paper I analyze whether international trade contributes to per capita income convergence across countries. The analysis focuses on four important post-1945 multilateral trade liberalizations. To identify trade's effect on income dispersion, in each case I use a difference-in-differences'...

We develop a method for decomposing countries' observed export prices into quality versus quality-adjusted-price components using information contained in their trade balances. Holding observed export prices constant, countries with surpluses are inferred to offer higher quality than countries...

A partir de inicios del presente siglo, el espectacular y prolongado auge de precios de las commodities trajo aparejado un drástico cambio en la configuración macroeconómica regional. Ello tuvo su correlato en la cambiante naturaleza de los dilemas enfrentados por la política económica....

I provide new estimates of border frictions for 14 countries using local, national, and international Big Mac prices. I find that borders generally introduce only small price wedges, far smaller than those observed across New York City neighboring locations.

We examine the role of cross-border input linkages in governing how international relative price changes influence demand for domestic value added. We define a novel value-added real effective exchange rate (REER), which aggregates bilateral value-added price changes, and link this REER to...

Does trade within a country affect welfare and productivity? What are the magnitude and consequences of costs to such trade? To answer these questions, we exploit unique Canadian data to measure internal trade costs in a variety of ways – they are large, and vary across sectors and...
