This Paper introduces the concepts of direct and indirect factor trade utility functions and uses them to derive Marshallian and Hicksian factor content functions, which express the quantities of factors embodied in net exports as a function of the economy's factor prices and endowments. The...

This paper presents a compact derivation of the determinants of changes in the equilibrium real exchange rate (the price index of non-traded goods relative to traded goods) in a small open economy with any number of goods and factors. It is shown that the change in the real exchange rate equals...

This paper examines the optimality of export subsidies in oligopolistic markets, when home and foreign firms have different costs and there is an opportunity cost to public funds. Subsidies are found to be optimal only for surprisingly low values of the shadow price of government funds, and if...

In this paper we consider the case for subsidies towards firms which generate R&D spillovers in open economies. We show that in the presence of strategic behaviour by firms many expected results are overturned. Local R&D spillovers to other domestic firms may justify an R&D tax rather than a...

This paper explores the links between international trade theory and the practice of trade and industrial policy in open economies, with special attention to three areas where theoretical lessons have been misunderstood in policy debates. It argues that the ‘concertina rule’ for tariff...

What kind of tariff reform is likely to raise welfare in situations where tariff revenue is important? Uncertainty about specification and risk from imprecise parameter estimates of any particular specification reduce the credibility of simulation estimates. A promising alternative is to develop...

We show that relaxing the assumption of CES preferences in monopolistic competition has surprising implications when trade is restricted. Integrated and segmented markets behave very differently, the latter typically implying a form of reciprocal dumping. Globalization and lower trade costs have...

We characterize how firms select between alternative ways of serving a market. ``First-order" selection effects, whether firms enter or not, are extremely robust. "Second-order" ones, how firms serve a market conditional on entry, are less so: more efficient firms will select into the entry mode...

This paper discusses the place of oligopoly in international trade theory, and argues that it is unsatisfactory to ignore firms altogether, as in perfectly competitive models, or to view large firms as more productive clones of small ones, as in monopolistically competitive models. Doing either...

This Paper extends the theory of multinational corporations, identifying three distinct influences of internal trade liberalization by a group of countries on the level and pattern of inward foreign direct investment (FDI). First, the tariff-jumping motive encourages plant consolidation. Second,...
