In the present paper, we consider a two-country, two-good, two-factor general equilibrium model with CIES non-linear preferences, asymmetric technologies across countries and decreasing returns to scale. It is shown that aggregate instability and endogenous fluctuations may occur due to...

This paper studies the impacts and determinants of trade policy. I use data on applied tariff protection of world countries over 2001-2007 to estimate sector-level trade elasticities. I then calibrate a structural gravity model of world trade. I compute the impacts of trade agreements which were...

Import price elasticity tends to be under-estimated due to the omission of quality effects. This dissertation aims to fill this gap by analyzing 1) how quality effects affect the estimation of import price elasticity, 2) the impact of quality innovation in the various goods sectors of an economy...

The empirical U-shaped pattern between product diversification and economic development has been widely examined, but here we analyze the determinants of diversification. We find that a high level of rent-seeking activities has a large impact on the diversification of nations : in countries...

This paper analyses empirically the role of financial market imperfections in the way countries' exports react to a currency depreciation. Using quarterly data for 27 developed and developing countries over the period 1990-2005, we find that the impact of a depreciation on exports will be less...

Estimations of gravity equations specified in logarithm generally conclude that the distance elasticity of trade has increased over time despite globalization. In contrast, building on Santos Silva and Tenreyro (2006), this elasticity is estimated to have been stable around 0.65-0.70 since the...

This article presents a theory of aid as trade. I assume that aid is a payment for an invisible export of strategic services to a large donor country seeking diplomatic goodwill and exclusive strategic use of a small country's territory, oceanic space and airspace. In a formal two countries-two...

A computable general equilibrium model is applied to evaluate the opportunity costs of not adopting Bt cotton, a genetically-modified (GM) insect resistant cotton, in Benin, Burkina- Faso, Mali, Senegal, Togo, Tanzania, and Uganda when it is adopted in other countries. Our model uniquely employs...

This paper aims at reviewing the literature on international trade and sustainability. In the neoclassical sense sustainability is interpreted as the imperative to maintain constant consumption over time. The literature provides several indicators to assess sustainability empirically....

This note investigates the impact of (international) technology transfer on optimal pollution taxation. To use a patented pollution abatement technology, the polluters subject to the emissions tax only pay fixed license fees to an (international) eco-industry (whose profits are shared among...
