An interindustry model relating gross output to the availability of primary inputs is used to examine supply linkages associated with national energy production. The results of calculations for US data highlight the importance of extractive energy sectors in intermediate production, and identify supplying sectors that have the potential of restricting energy output. The use of this model as a means to simulate the impact of alternative energy-allocation programmes on gross output is discussed and the results of one simulation are presented.

This paper uses the direct-cost estimates for air pollution abatement developed for an earlier study (Miernyk and Sears, 1974) to derive technical coefficients for several simulated abatement activities in West Virginia. Output and relative price effects are calculated for particulate matter abatement and two sulfur dioxide abatement alternatives, using a static input-output model.

This paper reports an evaluation of the econometric model developed by Regional Econometric Models Inc. for the South Coast Air Quality Management District. The analysis is focused on the in-sample performance, forecasting ability, and characteristics in impact analysis of the model. The trade-offs implicit in the performance of this model relate directly to questions of explanatory power. In particular, the model is characterized by well-specified structural equations that enhance its ability to formulate policy-relevant simulations. This may come at the cost of predictive ability in a statistical sense. Choices related to this trade-off are at the heart of applied regional analysis.

This paper concerns the structure and application of an econometric model of the Pittsburgh region. A distinction is drawn between forecasting models and those to be used for policy simulation. With this in mind, a simulation-oriented model based on annual data is specified and applied.

This unique Handbook examines the impacts on, and responses to, economic geography explicitly from the perspective of the behaviour, mechanics, systems and experiences of different firms in various types of industries. The industry studies approach allows the authors to explain why the economic geography of these different industries exhibits such particular and diverse characteristics
