Modelling external trade flows : new approaches and their implications for economic
policy,
by Joaquim Oliveira Martins.
This article is a survey of the recent approaches on modelling trade flows and their implications for economic policy. First, the main results of the usual models for estimating price and income elasticities of external trade will be recalled. To take essential they were based on perfect competition assumptions and their policy recommendations were largely used for managing exchange rates or choosing strategies for developing countries insertion in international trade. That make interesting to compare those models with the new theoretical tools which aim at introducing imperfect competition conditions in the explanation of trade flows. We then set out the main models of the new trade theory and we also try to draw their empirical implications. Namely, taking into account product differentiation strategies or increasing returns to scale bring about a set of new variables among the determinants of trade flows. Among others, the links between growth, exchange rates and the external balance constraint can be enlarged. The last part of the paper tackles with competitiveness analysis.
