Our paper integrates results from trade-in-task theory into mainstream trade theory by developing trade-in-task analogues to the four famous theorems (Heckscher-Ohlin, factor price equalisation, Stolper-Samuelson, and Rybczynski) and showing the standard gains-from-trade theorem does not hold...

This paper applies a novel empirical approach to characterising the horizontal-ness and vertical-ness of affiliates based on Yeaple's complex FDI concept. In its simplest form, horizontal-ness is measured as affiliates' local sales share while their vertical-ness is measures as their share of...

Competition between opposing lobbies is an important factor in the endogenous determination of trade policy. This paper investigates empirically the consequences of lobbying competition between upstream and downstream producers for trade policy. The theoretical structure underlying the empirical...

This paper shows that the results of Venables (1987) depend critically on the assumption that there are no fixed costs of trade. The introduction of fixed costs of exporting, while making the model more consistent with the empirical evidence, leads to the opposite conclusion that technological...

The theory of comparative advantage is at the core of neoclassical trade theory. Yet we know little about its implications for how nations should conduct their trade policy. For example, should import sectors with weaker comparative advantage be protected more? Conversely, should export sectors...

We estimate productivities at the sector level for 72 countries and 5 decades, and examine how they evolve over time in both developed and developing countries. In both country groups, comparative advantage has become weaker: productivity grew systematically faster in sectors that were initially...

This chapter (to appear in the forthcoming Handbook of International Economics, Vol. 5) develops a framework with which to interpret and survey answers to the question: how does increased openness affect aggregate welfare in a typical developing country? We decompose answers into four...

In the absence of distortionary tax and spending policies, freer immigration and trade for a country would often be supported by similar groups thanks to similar impacts on labor income. But government policies that redistribute income may alter the distributional politics. In particular,...

What are the gains from international trade? And how do immigrants influence this process? While economists have considered these questions before, particularly in the context of aggregate trade flows, there has been no work assessing the relation between immigration and international trade in...

This paper examines the extent to which the process of globalization can explain the observed widening in the cross--country distribution of output--per--worker. In particular examine whether the opening up of trade in a Hecksher--Ohlin type model of trade can explain the observed changes. On...
