In the analysis of bilateral trade flows, reported trade of zero or missing observations are quite common and this is a problem when estimating log-linear gravity equations. This has caused many researchers to either ignore the zero trade flows or to replace the zero with a small positive...

We review theoretical and empirical work on the economic effects of the United States and China trade relations during the last decades. We first discuss the origins of the China shock, its measurement, and present methods used to study its economic effects on different outcomes. We then focus...

Traditional computable general equilibrium (CGE) models based on the Armington assumption fail to capture the extensive margin of trade, and thereby underestimate the trade and welfare effects of trade opening. To address this problem, this paper introduces the Melitz (2003) theoretical...

We scrutinize the impact of international productivity gains (spillovers) induced by imports and exports on optimal tariffs. First, we solve a stylized 2x2 trade model of a large open economy and show that (a) productivity gains via exports and imports both reduce the strategically optimal...

We carry out an indirect inference test of two versions of a computable general equilibrium (CGE) model of world trade. One of these, the ‘classical’ model,is well-known as the Heckscher-Ohlin-Samuelson model of world trade, in which countries trade homogeneous products in world markets and...

This document provides a technical description of the WTO Global Trade Model developed by the Center for Global Trade Analysis (GTAP) and the World Trade Organization (WTO). The model can be used to generate global trade projections and to assess the medium and long run effects of a wide range...

This volume was prepared by Inga Heiland while she was working at the Ifo Institute. It was completed in July 2016 and accepted as a doctoral thesis by the Department of Economics at the University of Munich. It comprises five chapters addressing one or more aspects of international trade and...

Trade and investment can be effective means of implementation of the 2030 Sustainable Development Agenda. However, stand-alone trade and investment liberalization policies aimed at enhancing economic development may have negative side-effects on non-economic facets of sustainable development. As...

We examine the empirical evidence bearing on whether UK trade is governed by a Classical model or by a Gravity model, using annual data from 1965 to 2015 and the method of Indirect Inference which has very large power in this application. The Gravity model here differs from the Classical model...
