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...

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...

A recent paper in which embodied land appropriation of exports was calculated using a physical input-output model (Ecological Economics 44 (2003) 137-151) initiated a discussion in this journal concerning the conceptual differences between input-output models using a coefficient matrix based on...

This paper investigates how changes in the international division of labor can contribute to reducing CO2 emissions. The mitigation potential and costs implied by this mechanism are analyzed. Implications for the aluminium sector are assessed, including changes in the price of aluminium when...

Abstract. This paper presents a new approach for estimating the amount of carbonembodied in a product consumed in a given economy, taking account of where the inputsto that product were extracted and processed all along the supply chain. The method isgeneralized to apply to all factor inputs,...

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 &degree;ows and region-specific prices. The original model is a linear program that, based on comparative advantage...

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...

Significant economic disparities among China's Eastern, Central, and Western regions pose unequivocal challenges to social equality and political stability in the country. A major impediment to economic development, especially in the poor, remote Western region, is the shortage of transportation...
