We develop the rectangular choice-of-technology model with factor constraints, or RCOT, for analysis of the economy of a single region, or of multiple regions in the context of a model of the world economy. RCOT allows for one or more sectors to operate more than one technology simultaneously,...

We develop the rectangular choice-of-technology model with factor constraints, or RCOT, a linear programming input-output model for analysis of the economy of a single region. It allows for one or more sectors to operate more than one technology simultaneously, with the relatively lowest-cost...

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...

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...

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. Major properties of the model are demonstrated, including the sources...

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...
