Gravity equations have been used for more than 50 years to estimate ex post the partial effects of trade costs on international trade flows, and the well-known - and traditionally presumed exogenous - "trade-cost elasticity" plays a central role in computing general equilibrium trade-flow and...

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...

We build a model of tacit collusion between firms that operate in multiple markets to study the effects of trade costs. A key feature of the model is that cartel discipline is endogenous. Thus, markets that appear segmented are strategically linked via the incentive compatibility constraint....

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 consider an international cartel whose members interact repeatedly in their own as well as in third-country segmented markets. Cartel discipline-an inverse measure of the degree of competition between firms-is endogenously determined by the cartel’s incentive compatibility constraint (ICC),...

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...

What drives firms' geographic diversification in international markets? I build a model to show that if some export costs are sunk and shared between alike destinations, the decision of a firm to enter a market is a function of its experience in a similar one. Using a rich firm-level dataset for...

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...

A country or firm's position in the value chain will largely depend on its comparative advantage, and therefore the mix of skills and resource endowments it brings to international production. For some, this might initially involve specialising in the labour intensive segments while others may...

In this paper the authors develop an innovative 21 sector computable general equilibrium model of Armenia to assess the impact on Armenia of a Deep and Comprehensive Free Trade Agreement (DCFTA) with the EU, as well as further regional or multilateral trade policy commitments. The authors find...
