Do scale economies contribute to our understanding of international trade? Do international trade flows encode information about the extent of scale economies? To answer these questions we examine the large class of general equilibrium theories that imply Helpman-Krugman variants of the Vanek...

This paper sets out a theory of how openness to international goods markets affects pollution concentrations. We develop a theoretical model to divide trade's impact on pollution into scale, technique, and composition effects and then examine this theory using data on sulfur dioxide...

This paper provides a new and simple model of endogenous horizontal product differentiation based on a standard demand structure derived from quadratic utility. One objective of the paper is to explain the “empirical Bertrand paradox” – the failure to observe homogeneous product Bertrand...

This paper investigates the effect of endogenous horizontal product differentiation on trade patterns and the gains from trade under Bertrand and Cournot oligopoly. Firms differentiate their products to mitigate competition, but only if the investment required is not too high. Investment in...

This paper develops a model in which the rivalry of oligopolistic firms serves as an independent cause of international trade. The model shows how such rivalry naturally gives rise to "dumping" of output in foreign markets, and shows that such dumping can be "reciprocal" -- that is, there may be...

This paper examines the welfare effects of a tax on foreign purchases of domestic land. Using a simple static framework the paper shows that an appropriately chosen tax will generally be welfare-improving for the domestic country.

This paper examines the relationship between the Toronto Stock Exchange (TSE) and election polls during the 1988 Canadian General Election campaign. Two hypotheses are investigated: first, did polls influence the TSE, and secondly, if so, did the nature of the influence suggest that investors...

We analyze the welfare effects of conditional trade adjustment assistance (i.e. assistance that is received only if displaced workers remain unemployed), and compare the conditional program with unconditional assistance. Taking the level of assistance as exogenous, we show that either the...

Two recently improved sets of cross-country panel data are combined in order to re-examine the effects of population growth and fertility on economic growth. Using a 107 country panel data set covering 1960-85, we find that high birth rates appear to reduce economic growth through investment...

This paper reviews the literature on strategic trade policy. Strategic trade policy is defined as trade policy that conditions or alters a strategic relationship between firms, implying that strategic trade policy focuses primarily on trade policy in the presence of oligopoly. The key point is...
