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...

Much potential for trade liberalization exists in industries and markets with trade barriers that are prohibitive for all or many firms. In standard political economic theories of trade policy, observed prohibitive barriers must be globally optimal according to static government preferences,...

This paper shows that a regional bias resulting from trade integration alters the transmission of a countryś monetary policy by shifting the burden of the exchange rate adjustment towards the less integrated trading partners. I first develop a simple model which illustrates how a concentration...

Using a novel common econometric specification, we examine the measurement of three important effects in international trade that historically have been addressed largely separately: the (partial) effects on trade of economic integration agreements, national borders, and bilateral distance....

We develop a theory of economic disintegration that features both endogenously formed tax and trade policies. We show very generally that the economic disintegration of a country from an economic union leads to a deeper integration of international trade institutions. Moreover, we set up a...

This paper shows that regional trade integration shifts the burden of the exchange rate adjustment towards the less integrated trading partners. Thus, they bear the cost of trade balance expansion, while competitive exchange rate moves vis-a-vis RTA trading partners result in no expansion or...

We develop a theory of economic disintegration with both endogenously formed tax and trade policies. We show very generally that, contrary to conventional wisdom, a country’s disintegration from an integrated area leads to a deeper integration inside the area. Similarly, the departure of a...

Traditional analysis of customs union formation suggests that it leads to an increase in members' external tariffs. This paper stresses two aspects of European trade and trade policy - a large volume of intra-industry trade between similar countries and a political motivation for tariffs - and...

We examine the impact of (and links between) two types of economic integration on the stability of multimarket collusion when firms interact in quantities in segmented markets: (1) multilateral trade liberalization, captured by a reduction of trade costs across all markets; and (2) preferential...
