The claim by global trade modelers that the potential contribution to global economic welfare of removing agricultural subsidies is less than one-tenth of that from removing agricultural tariffs puzzles many observers. To help explain that result, this paper first compares the OECD and...

This paper provides estimates of the economic impact of initial adoption of genetically modified (GM) cotton and of its potential impacts beyond the few countries where it is currently common. Use is made of the latest version of the GTAP database and model. Our results suggest that by following...

Four West African nations have demanded the WTO’s Doha Development Agenda include a Cotton Initiative that involves two issues: cutting cotton subsidies and tariffs, and assisting farm productivity growth in Africa. This paper provides estimates of the potential economic impacts of (a)...

We develop a method that allows one to compute incomplete-market equilibria routinely for Markovian equilibria (when they exist). The main difficulty to be overcome arises from the set of state variables. There are, of course, exogenous state variables driving the economy but, in an incomplete...

China has always strived for self-sufficiency in farm products, particularly staple foods. Its rapid industrialization following its opening up to global markets during the past two decades has been making that more difficult, and its accession to the WTO may add to that difficulty. New...

The first generation of genetically modified (GM) crop varieties sought to increase farmer profitability through cost reductions or higher yields. The next generation of GM food research is focusing also on breeding for attributes of interest to consumers, beginning with ‘golden rice’, which...

We estimate the impact of global merchandise trade distortions and services regulations on agricultural value added in various countries. Using the latest versions of the GTAP database and the GTAP-AGR model of the global economy, our results suggest real net farm incomes would rise in...

This paper provides new estimates of the global gains from multilateral trade reform and their distribution among developing countries in the presence of trade preferences. Particular attention is given to agriculture, as farmers constitute the poorest households in developing countries but the...

This paper analyses the incentives to participate in and the stability of international climate coalitions. Using the integrated assessment model WITCH, the analysis of coalitions’ profitability and stability is performed under alternative assumptions concerning the pure rate of time...

We use randomized program offers and multiple follow-up survey waves to examine the effects of entrepreneurship training on a broad set of outcomes. Training increases short run business ownership and employment, but there is no evidence of broader or longer run effects. We also test whether...
