PRODUCT-MIX AND TECHNOLOGICAL CHANGE WITHIN THE LEONTIEF INVERSE

ABSTRACT. Intertemporal differences in input-output coefficients can be attributed to technological change and to changes in the mix of products composing the aggregate sectors of input-output models. In this work, we develop the theoretical foundation necessary to separate these changes for both the structural and Leontief inverse matrices. Using this foundation, we examine the relative empirical importance of technological and product-mix change. The product-mix effect is then combined with RAS estimates of the technological effect to form updated estimates of the inverse. Results show that the accuracy of updated input-output coefficients can be improved in this manner.     

FORCES FOR CHANGE IN THE GOVERNANCE OF BRITISH AND AMERICAN UNIVERSITIES

Government control of colleges and universities has been increasing in recent years. The challenge for higher education is how to make institutions properly accountable but less controlled by government. The experience in this regard in the United Kingdom and the United States is compared. The danger in both nations is that left unchecked, control will leave universities resembling regulated public utilities. American and British academics can learn from each other on how to avoid such a fate.     

PROFITS, CRISES AND INDUSTRIAL CHANGE 2: THE EXPERIENCE OF CANADA 1950—1981

The paper measures the rate of profit and its components in Canadian manufacturing for 1950 - 1981. The rate of profit has been reduced by rises in the real wage and the technical composition of capital, partially offset by a devaluation in the means of production and a reduction in turnover times. The value of labour power and therefore the rate of exploitation have not changed. The rate of profit has consistently fallen throughout the period. These results are consistent with a theory that the falling rate of profit is endogenous to capitalism.     

INDUSTRIAL CENTERS AND REGIONAL GROWTH IN THE PRESENCE OF LOCAL INPUTS*

ABSTRACT. A large proportion of regional production takes place in nontraded goods and services. In addition, significant productivity increases can be observed in some segments of this sector. Starting from these two empirical observations we construct a model of growth in a two-region setting with factor mobility. The growth process is based on endogenous technological change in the nontraded input sector, whose output serves as an input in the production of one of the two final goods, the so-called industrial good. We consider two extreme cases, one with locally limited, the other with interregional knowledge spillovers. Conditions are established under which interior solutions with production of local inputs and steady-state growth in both regions result, and others under which we find a core-periphery pattern with growth concentrated in one region only. The stability of the equilibria is discussed by considering the transition processes. Finally, it is shown that catching-up as well as leapfrogging may occur, if new technologies become available.

THE EFFECTS OF REGIONAL SCIENCE AND TECHNOLOGY POLICY ON THE GEOGRAPHIC DISTRIBUTION OF INDUSTRIAL R&D LABORATORIES*

ABSTRACT. The determinants of the geographic distribution of industry R&D activity are examined with particular emphasis on the role of university research as well as state science and technology programs. An analysis of a cross section of metropolitan areas indicates that industry R&D labs are located in areas with state science and technology programs, as well as in areas with higher levels of university research, larger quantities of non-welfare related local government spending, a better educated workforce, and a greater population density.     

REGIONAL INDUSTRIAL STRUCTURES AND ECONOMIC PROSPECTS IN THE FORMER USSR

The value of output, employment, and capital stock for each industrial sector for each oblast-level spatial unit in the former USSR, as well as differences in regional industrial structures are presented on the basis of a unique set of unpublished Goskomstat data. Particular emphasis is placed on asessing the regions' relative raw materials endowments, especially with respect to energy resources, and on the degree of diversification, or lack of same, within their industrial structures. The extremely uneven distribution of industrial capacity is examined in light of its role in determining the near- and longer-term economic prospects for the various republics and regions.     

REGIONAL VARIATIONS IN TECHNOLOGICAL CHANGE AND IN POTENTIAL GAINS FROM CONSOLIDATION AMONG U.S. COMMERCIAL BANKS

ABSTRACT. This paper investigates the regional variations in the impact of technological change and in gains from consolidation among U.S. commercial banks. We estimate a multiproduct translog cost function with the appropriate regional dummy variables. Technological change, ray scale economies and scale biases in technological change are estimated for each region. Furthermore, pairwise expansion path economies between all the regions are calculated to evaluate the potential gains from interregional consolidation. In general Southwest banks had the worst and Southeast the best technological change. There is substantial disparity across regions. It also appears that technological change increased the efficient size in the Midwest and Southwest regions and reduced it in the West, Northeast and Southeast. Banks in all regions show ray economies of scale, affirming the need for larger banks if output mix remains constant. Finally, the results support takeover of regional banks by the Money Center banks but not vice-versa, and favor consolidation among regional banks. The biggest potential gains accrue from mergers of Southeast banks with either Midwest or Southwest banks and the least gains are derived from mergers between Midwest and Southwest banks.     

制度变迁与中国城市的发展及空间结构的历史演变

我国的城市发展水平同经济发展水平的偏离,说明对城市发展及其空间结构演变分析不能仅局限在物质经济领域,需要我们寻求影响城市发展及其空间结构变化的新因素一制度因素,把制度作为影响城市发展及其空间结构的一个主要的变量,来对此加以解释。为此,本首先构建了“制度变迁一城市发展变化”的理论框架,然后用该理论从宏观和微观两个方面来检验1949-1998年间制度变迁对城市发展及其空间结构的影响。与西方国家的以市场经济为主要动力驱动型的城市发展模式不同,中国城市的发展及其空间结构的演变在很大程度上是制度变迁而诱致的结果。但不同的制度对城市数量增长、组织体系及空间布局和对城市空间结构演变的作用力度又不尽相同。改革开放后,由于制度变迁带来的激励作用,中国城市获得了快速发展,城市空间结构快速变化。但与此同时,中国城市化的发展水平与相同发展条件下的世界城市化水平的差距却在拉大。而且随着市场经济体制的逐步完善,影响城市增长及空间结构的演变力量的因素越来越趋于分散化,制度变迁对城市发展所带来的激励作用正在弱化。为适应新世纪我国城市发展的战略目标,需要进行体制创新,为中国城市的发展及其空间结构的演变提供新的制度支持。
