This paper describes the World Trade Model, a linear program that determines world prices, scarcity rents, and international trade flows based on comparative advantage in a world economy with m regions, n goods, and k factors. The new model generalizes the World Model of Leontief et al. (1977)...

This paper describes an extension of Duchin's world trade model to include the explicit representation of transportation costs, permitting the endogenous determination of bilateral trade flows and region-specific prices. The original model is a linear program that, based on comparative advantage...

This article describes the contribution economists can make in uncovering energy choices capable of reducing carbon emissions on a global scale. All production and consumption activities involve the use of energy, and economists possess theoretical and analytic frameworks relating production and...

This paper evaluates the role of trade as mechanism of economic adjustment to the impacts of climate change on agriculture. The study uses a model of the world economy able to reflect changes in comparative advantage; the model is used to test the hypotheses that trade can assure that, first,...

One of the key areas for lifestyle change in the interest of sustainable consumption is the household diet. This paper identifies concrete scenarios for dietary alternatives to high calorie diets rich in fats and sugars, based on the specialized nutrition literature, that are likely to have...

Change in ownership of large land resources in the northeastern United States is reshaping the economic and cultural landscape. The Adirondack Park of New York State has taken aggressive steps toward land conservation through public land acquisition and private land planning. The State's...

Water stress in Mexico is intimately linked to agriculture, as irrigation claims 75% of national water withdrawals. The Mexican mix of irrigation technologies is dominated by flood techniques, utilized on 93% of irrigated land, while drip and sprinkler systems, both with higher application...

With growing demand for fresh water and uncertain supplies, there is an increasing concern about future water scarcity. Since most freshwater withdrawals are for agriculture, reliance on water embodied in imported food (trade in ‘virtual water’) is a possible strategy to provide food to...

This paper uses the World Trade Model with Climate Sensitive Land (WTMCL) to evaluate possible future land-use changes associated with adaptations to climate change in a globalized world. In this approach, changes in regional agricultural production, which are based on comparative advantage,...
