We examine how globalization affects trade patterns and welfare when conflict prevails domestically. We do so in a simple model of trade, in which a natural resource like oil is contested by competing groups using real resources ("guns"). Thus, conflict is viewed as ultimately stemming from...

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...

Risks that are associated with an uncertain trading world have been dealt with using two different techniques in the literature: defensive, or insurance approaches, and preventive, or self-protection approaches. Much of the earlier work was emphasized by security issues but with the end of the...

This paper discusses the normative foundation of a global competition regime. It asks: What kind of normative values do we need? What objectives ought we to pursue? Why value economic competition at such a tough time as this? Are the disputes on these issues in the US and EU jurisdictions likely...

This paper presents a simple model where microfounded dynamics of cultural identity are endogenous and interact with an international trade equilibrium. This process generates a strong home bias under autarky. We then show that goods market integration causes a phenomenon of cultural divergence,...

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...

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...

This paper reviews the most significant recent developments in the theory of trade agreements. The paper offers an integrated approach to evaluating trade agreements, and uses the approach to present results on preferential and multilateral trade agreements. The paper identifies also several...

Numerical simulation exercises to analyze the impacts of potential changes in non-tariff policies commonly use ad valorem equivalent tariff treatment even though estimated impacts using explicit model representation and ad valorem equivalent treatments will differ. The difficulty for modellers...
