Modeling the Impact of Non-Tariff Barriers in Services on Intra-African Trade: Global Trade Analysis Project Model

Tariff and Non-Tariff Barriers to Trade

that restrict trade between countries in agricultural commodities. Many of these policies are now subject to important disciplines under the 1994 GATT agreement that is administered by the World Trade Organization (WTO). The paper is organized as follows. First, tariffs, import quotas, and tariff rate quotas are discussed. Then, a series of non-tariff barriers to trade are examined, including v...

Non-Tariff Barriers and Trade Liberalization∗

This paper shows that governments have no incentive to introduce non-tariff barriers when they are free to set tariffs but they do when tariffs are determined cooperatively. We then show three results. First, with trade liberalization, there is a progression from using tariffs only to quotas, and to antidumping constraints (when quotas are jointly eliminated). Second, there is a narrowing of th...

Endogenous Tariff Formation with Intra-Industry Trade

Previous theoretical contributions on endogenous tariff formation have focused on trade models with homogeneous goods and constant returns to scale. This paper investigates the political equilibrium of trade policy when economic structure is instead characterized by differentiated products and increasing returns to scale and there exists intra-industry trade. The result shows that endogenous ta...

Trade in Services: Does Gravity Hold? A Gravity Model Approach to Estimating Barriers to Services Trade

This paper assesses the determinants of trade in services using a gravity model, with particular attention given to the role of barriers to services trade. Initially, the application of the gravity equation to services trade is examined. A variety of econometric estimators are tested and the Hausman-Taylor model is found to be the best estimator. The gravity model fits services trade flows in a...
