A Computational Approach to the Study of Regionalism

Abstract:

 

Analytic research in the theory of regional trade agreements has produced a literature with very few general propositions. Not only are results ambiguous, but clear results are only available under very restrictive sets of assumptions. This study develops a technique that is designed to overcome these two difficulties. What we do is to utilise computational techniques to determine the circumstances under which propositions are true. Using a simplified (fewer countries and commodities) CGE model and sampling theory to tell us how many equilibria to compute, we determine the percentage of cases for which a given proposition holds. In this way, by mapping out the set of parameter values for which a result occurs we can get a feel for which statements are generally true and which are not. In addition, when the propositions are not true we will be able to sharpen the intuition for why this is the case. This approach will help reduce the degree of ambiguity of some analytic results and (though still theoretical) end up being of some relevance from a policy perspective.
