A computable general equilibrium model of Egypt is developed to analyze proposed reforms in its trade policies, including a partnership agreement with the European Union. The model has multiple trading regions and allows for administrative trade barriers and tariffs. The paper reports computations of the revenue impacts of trade liberalization and the required changes in distortionary commodity taxes to maintain a fixed real government budget. Egypt's greatest potential gains come from removing its administrative trade barriers while adopting globally free trade. The partnership agreement with the EU could lower or raise Egypt's welfare, depending on prior trade reform. 相似文献

Geographers deal with global and local space and their interrelationships and thus bring new insights, perspectives, and methods to global questions. This is appealing to futurists since the principle of ‘think globally-act locally’ has been an inspiration for many years. In this paper I explore how old and new approaches in geography, as well as new information technologies such as the World Wide Web (WWW) and Geographic Information Systems (GIS), might contribute to global modeling. I briefly review also the history of global economy models to discover lessons for future attempts to construct global models, not least how prevailing paradigms and institutional expediency determine the intellectual effort, and its impact. I then describe some of the new directions being undertaken by global modelers, quantitative geographers and regional scientists in the 1990s, and the possibilities and challenges for the next few years, and their contribution to the knowledge building process and its context. 相似文献

In this study, we present a simple analytic framework that divides the real estate market into two markets: the market for real estate space and the market for real estate assets. After describing the size and character of flows and stocks in the U.S. real estate market, we use our framework to demonstrate the important connections between the space and asset markets. We illustrate how these real estate markets are affected by the nation's macroeconomy and financial markets, tracing out the impacts resulting from various exogenous shocks on rents, asset prices, construction and the stock of real estate. 相似文献

The distribution of world output between countries, and between social groups within countries, is central to long-term development prospects. Unequal shares mean unequal influence over the future direction of world affairs. The level and structure of demand are conditioned by the distribution of financial resources; while the power to influence the course of development is itself tied to the resources that can be marshalled in support of one's objectives. Two forecasting techniques, scenario construction and global modelling, are used to assess these relationships and explore the consequences of one possible ‘future history’ in which distribution worldwide does eventually begin to improve. Striking limitations to most development strategies are identified; without a wide-ranging set of changes, the prospects for improved distribution—and relief of poverty—are bleak. 相似文献

This article describes the macroeconomic model used in an ongoing study of technology policies and North-South relations. Other aspects of the study have been described elsewhere [1,2]. We examine here the rationale for the theoretical structure used in the model, the details of the equations, and a computation of solutions. To illustrate the dynamics of the model, a brief discussion is also given of the preliminary results that indicate critical relationships between domestic technology and income distributions and the North-South terms of trade. The results are based on a calibration of the model using data for Brazil and the United Kingdom. 相似文献

We estimate quarterly return series from March 1984 through December 1989 for 10 classes of thrift assets using the statistical cost-accounting methodology of Hester and Zoellner (1966). We then use these return series to estimate mean-variance efficient frontiers for all thrifts, for thrifts that were well capitalized two years earlier and for thrifts that were insolvent two years earlier. Our results show that neither the asset restrictions existing before nor those in effect after passage of the Financial Institutions Reform, Recovery and Enforcement Act of 1989 would have prevented thrifts from reaching most of the portfolios along the efficient frontier. The actual portfolio chosen by well-capitalized thrifts is close to the estimated efficient frontier, while the actual portfolio chosen by insolvent thrifts is located far from the frontier in the high-risk end of investment space. These findings, coupled with the high proportion of nontraditional assets in the actual portfolio chosen by insolvent thrifts, support the hypothesis that moral hazard induced thrifts to take on investments that were excessively risky from the deposit insurer's point of view. 相似文献

Computer simulation of the world problematique offers a policy maker an interesting opportunity to see the dynamics of relationships within and between the global subsystems of which food and agriculture is one. The four major modelling studies reviewed in this article make assumptions about the possible level of food supply, technological and economic impacts on production, ecological consequences, and social and political factors influencing demand. Following their analysis of agricultural data inputs in all these areas, the authors discuss the type of policy measures likely to be recommended on the basis of global modelling. 相似文献
