This paper proposes an integration of life-cycle assessment methods with a new input-output model of the world economy to analyze the environmental and economic implications of alternative future diets. The paper reviews findings by industrial ecologists about the energy and land required for the production and consumption of alternative foods and diets in(More)
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, satisfying global agricultural demand will not be jeopardized,(More)
This paper argues that resources constitute the fundamental area of overlap between the interests of input-output economists and industrial ecologists. Three misconceptions about input-output economics obscure this fact: the frequent failure to utilize combined quantity and price input-output models, treatment of value-added as a monetary concept only, and(More)
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 and the minimization of factor use, determines regional(More)
Communities and governments in all societies provide social assistance for temporary setbacks and long-lasting misfortunes that befall individuals and households. EU countries have traditionally provided a relatively extensive safety net supported by the success of their market economies. Now EU social welfare systems are being subjected to massive shifts(More)
In the early 21st century the extensive clearing of forestland, fresh water scarcity, and sharp rises in the price of food have become causes for concern. These concerns may be substantially exacerbated over the next few decades by the need to provide improved diets for a growing global population. This study applies an inter-regional input-output model of(More)
A classification scheme for household lifestyles, and another for the activities of which they are comprised, are described as a necessary starting point for the analysis of the environmental impact of changes in household consumption. A household’s lifestyle is defined by how it carries out the activities, and households with similar lifestyles are grouped(More)
This paper describes the mathematical basis for input-output economics, the major types of models, and the underlying economic theory. The features of these models that make them especially well suited for understanding the connections between the economy and the environment are emphasized throughout. These include the dual physical and price(More)
