Water's role in manufacturing technologies has received limited attention. A KLEM model of the sector's technology is extended to include two facets of water use: intake and recirculation. Three annual cross-sectional surveys on plant-level water use are pooled and combined with census data to estimate this extended model for the Canadian manufacturing sector over the period 1981–1991. While Canada's water allocation regulations influence private water withdrawals, statistical tests support representing water intake as a variable input. Water intake is found to be a substitute for water recirculation, energy, labour and capital. The relationship between water intake and recirculation is stronger when water intake is process-related rather than related to cooling and steam production. Technological change has been biased in the direction of increased water intake and decreased water recirculation. 相似文献

The classic way of performing a market forecast for industrial products implies an econometric analysis of the historical data of consumption and their projections into the future. The present work illustrates a fresh approach to the problem; the demand for the product under study is evaluated in a mathematical model which takes into consideration the technological and commercial characteristics of this product and correlates it with competitive and substitutive products. Competitiveness is measured by assigning merit scores to the characteristics of the different products, and calculating the relevant “weights of importance” on the basis of the historical consumptions. Forecasts of consumption are made by estimating the future scores of the characteristics and extrapolating the weights of importance. An example of complete application of the model to the textile market in Italy is included. 相似文献

This article analyses the relationship between investment and savings for Angola using the Feldstein–Horioka puzzle, with monthly data from January 2000 to December 2013. Integer and fractional integration and cointegration techniques are employed to investigate the relationship between investment and savings. Several regression specifications are employed, concluding that the Feldstein–Horioka puzzle is not validated for the Angolan economy. Policy implications are derived. 相似文献

No End to the Racial Wage Hierarchy in South Africa? 总被引:2,自引:0,他引:2
The South African apartheid system formally ended with the election of the African National Congress at the first all-race elections held in 1994. As a result, racist policies such as color barring, that particularly hindered the advancement of black workers throughout the apartheid period, are no longer legal. Yet the legacy of apartheid may endure as a result of both the persistence of racial differences in human capital attributes and the possible continuation of discriminatory practices within employment. In this paper the authors examine the evolution of the racial wage hierarchy in the early post-apartheid era against the background of the long-term decline in racial wage disparities observed over the last years of the apartheid regime. They find evidence that the position of black workers between 1995 and 1997 actually deteriorated relative to the overall geometric mean wage, while that of colored, Asian, and white workers improved. 相似文献

Integrating the health services and insurance industries, as health maintenance organizations (HMOs) do, could lower expenditure by reducing either the quantity of services or unit price or both. We compare the treatment of heart disease in HMOs and traditional insurance plans using two datasets from Massachusetts. The nature of these health problems should minimize selection. HMOs have 30% to 40% lower expenditures than traditional plans. Both actual treatments and health outcomes differ little; virtually all the difference in spending comes from lower unit prices. Managed care may yield substantial increases in measured productivity relative to traditional insurance. 相似文献

Building the Planning Consensus: The Plan of Chicago,Civic Boosterism,and Urban Reform in Chicago, 1893 to 1915 下载免费PDF全文
Matthew P. McCabe 《American journal of economics and sociology》2016,75(1):116-148
Since its publication in 1909, Daniel Burnham's Plan of Chicago has been criticized for its lack of attention to social issues and for the failure of subsequent reconstruction projects to live up to the ambition of the plan. These criticisms assume that the Plan of Chicago was insufficiently progressive, or they evaluate the Plan by reference to the successes and failures of subsequent decades of urban reconstruction in Chicago. This article argues that the key to understanding the Plan of Chicago is to place it in its historical context. Burnham's Plan of Chicago was an expression of the tradition of Chicago civic boosterism and earlier city‐building practices as much as it was of the nascent profession of city planning. Finally, while the Plan did neglect housing, poverty, and other social questions, it did possess a social vision based on civic inclusivity, rather than economic inclusivity. The Plan can be read as a reform document based on the assumption that physical environment shapes individual character and social relationships. It assumed the creation of a unified and harmonious physical city would produce a contented and productive citizenry. In short, the Plan of Chicago deployed a transformative vision in the service of conservative goals. 相似文献

This study explores relationships between race, gender, agreeableness, openness to experience, contact, and a measure of attitudes toward diversity—universal‐diverse orientation (UDO). UDO consists of three attitudinal components: realistic appreciation (a cognition), comfort with difference (a feeling), and diversity of contact (a behavior). Results suggest that race, agreeableness, and openness relate to UDO attitudes, primarily due to the relationships of these variables with the behavioral component—diversity of contact. Identifying characteristics of tolerant people (e.g., agreeableness) and training managers in skills related to those characteristics may improve contextual performance and make managers better role models within the organizational context. © 2003 Wiley Periodicals, Inc. 相似文献
