Wally's research interests are in the area of agricultural and natural resource policy analysis and structural and sectoral adjustment in developing economies. His past work in energy economics has encompassed oil, natural gas, coal, oil shale, biomass, ethanol from agricultural sources, and solar energy. Most recently, most of his work has focused on agricultural trade and policy issues in developing economies, particularly in the Middle East, North Africa, and West Africa. Wally is co-director of the Center for Global Trade Analysis (GTAP). Many economic analyses of climate policies have used computable general equilibrium (CGE) models of the global economy. This class of model permits the analysis of policy impacts while considering all the substitutions and exchanges that occur in the global economy. The GTAP model and data base at Purdue is the leading global CGE model – to evaluate costs of abatement and to assess the spill-over effects of greenhouse gases (GHG) abatement policies via international trade and sectoral interaction. During the past decade, the Global Trade Analysis Project has filled an important need in the integrated assessment (IA) community by providing regular updates of world-wide input-output and bilateral trade data sets with sig­nificant disaggregation of regions and sectors, plus energy volume data. With its data base covering inputs/outputs and bilateral trade of 57 commodities (and producing industries) and 87 countries/regions, GTAP is able to capture broad sectoral interactions within domestic economies and international trade effects as well.
