摘要:

AbstractThe issue of global warming has sparked debate among scientists and policymakers over the past two years. Many studies have been undertaken in the U.S. and other nations to determine the potential severity of global climate change and appropriate policy responses. The U.S. Department of Energy is now conducting one such study of energy technology and policy options to mitigate greenhouse gas emissions. The study attempts to assess the emissions reduction potential and costs of several policies, using the FOSSIL2 integrated energy model. This article focuses on the preliminary results of a subset of eight policy cases. It discusses the modeling methodology, the formulation of these policies, draft results, and some policy insights.

摘要:

AbstractThis article attempts to assess the effects on an agricultural resource system of policies to maintain food self‐sufficiency in a centrally planned economy. Vietnam's case serves as an illustration. Experimentation with a system dynamics model of the food production system, incorporating relations concerning soil ecology and agricultural land management policy, serves as a basis for this assessment. Short‐run policies to increase production appear to be detrimental to maintaining food self‐sufficiency in the long run. it appears that a sustainable food production policy must incorporate soil conservation and improvement, and population control. Although difficult to implement in a market system, such a policy agenda may be feasible in a centrally planned ec

摘要:

AbstractThe primary focus of the research reported in this article was on measuring the value of information in a business firm. A five‐sector system dynamics model was developed and calibrated to an average firm in the U.S. metal‐can production industry. The model was used to test several propositions about the economic value of information. A framework in which to assess information value was developed, and the performance of the firm was assessed using cost, profitability, and efficiency measures for the information attributes of accuracy, timeliness, relevance, and reliability at the strategic, managerial, and operational decision‐making levels of the
