This thesis models trade flows between countries as a function of several variables, including those representing membership in multilateral trade agreements (MTAs). The objective of this research is to evaluate the impact of trade policies, trading costs, trade agreements and other demographic characteristics on exports of food and agriculture products. More specifically, the paper uses a gravity model augmented with three sets of dummy variables to estimate the impact of 13 trade arrangements on intra-bloc and extra-bloc trade. Results indicate that several MTAs enhance intra-bloc trading at the expense of non-members while others have been successful at increasing both intra-bloc trade and trade with the rest of the world. Findings further suggest that several arrangements had no significant effect on member trading and that a few have effectively reduced trade for members.
