This paper considers the evolution of global transportation usage over the past half century and its implications for supply chains. Transportation usage per unit of real output has more than doubled as costs decreased by a third. Participation of emerging economies in world trade and...

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...

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...

This paper studies the performance of China's exports during the 2008-2009 financial crisis. It focuses on the speed at which China's exports were hit by this downturn. Product-country monthly exports data is utilized. It is found that GDP growth rates of importing countries play an important...

Japan and India signed the much-awaited Comprehensive Economic Partnership Agreement (CEPA) on 16th February 2011. The CEPA will eliminate tariff on goods that account for 94% of their two way trade over ten years and will boost bilateral trade and investment. Indian exports which were subject...

What determines the relative gains from improving different parts of a transportation network? Ports and roads are key components of a country’s infrastructure to access international markets. I provide a framework to jointly estimate the quality of different ports and trade costs on normal...

We build a general equilibrium model of endogenous communication, quality control and trade. We derive a structural gravity equation from the model and show that exogenous communication costs raise the costs of quality control and have a larger impact on products with a lower elasticity of...

We describe a model that integrates a multi-regional input-output model of the U.S. (50 states and the District of Columbia) with the national highway network. Interstate commodity shipments are placed on a congestible highway network. Simulations of major choke-point disruptions redirect...

We show that the creation of the first integrated pan-European transport network during Roman times influences economic integration over two millennia. Drawing on spatially highly disaggregated data on excavated Roman ceramics, we document that interregional trade was strongly influenced by...
