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...

This paper proposes a new test of the Protection for Sale (PFS) model by Grossman and Helpman (1994). Unlike existing methods in the literature, our approach does not require any data on political organizations. We formally show that the PFS model predicts that the quantile regression of the...

We examine the sensitivity of simple calibration models of trade in imperfectly competitive industries to changes in model specification, as well as to changes in the calibration parameters. We find that not just the magnitude, but also the sign of the optimal trade policies is very sensitive to...

This paper provides a new heterogeneous firm model for trade where firms differ in their productivity and experience different market demand shocks. The model incorporates variations in trade policy, trade preferences, and the rules of origin needed to obtain them, to reflect real world...

This paper analyzes the role of network externalities and expectations about them in the formulation of trade policy. Their effects are studied in duopoly situations when products are compatible and when they are incompatible and when multimarket effects are possible. Network externalities and...

Ideas with regard to trade policy and economic development have changed radically since the 1950s. Then and now, it was recognized that trade policy was central to the overall design of policies for economic development. But in the early days, there was a broad consensus that trade policy for...

In contrast to recent literature, we show that market access requirements (MARs) can be implemented in a procompetitive manner even in the absence of threats in related markets. By focusing on subsidies that are paid only when the requirement is met, we show that a MAR can increase aggregate...

In this paper, the evolution of thought regarding protectionist trade policies in developed and in developing countries is examined and contrasted. In the developing countries distrust of markets and a belief in the infant industry argument led to highly protectionist trade regimes. The...

My topic is the question: what difference does the set of commercial policies chosen by a developing country make to its rate of economic growth? Three points are salient. First, in its present state, trade theory provides little guidance as to the role of trade policy and trade strategy in...
