Sample design and sample allocation methods are developed for random digit dialling in household telephone surveys. The proposed method is based on a two-way stratification of telephone numbers. A weighted probability proportional to size sample allocation technique is used, with auxiliary variables about the telephone coverage rates, within local telephone exchanges of each substrata. This makes the sampling design nearly “self-weighting” in residential numbers when the prior information is well assigned. A computer program generates random numbers for the local areas within the existing phone capacities. A simulation study has shown greater sample allocation gain by the weighted probabilities proportional to size measures over other sample allocation methods. The amount of dialling required to obtain the sample is less than for proportional allocation. A decrease is also observed on the gain in sample allocation for some methods through the increasing sample sizes.  相似文献

This research proposes an approach to measure hospital performance based on a generalization of Banker and Morey (1986) and Førsund (1996). This approach considers quasi-fixed inputs explicitly, calculates their implicit cost, and quantifies returns to scale. The performance measure is decomposed into allocative and technical inefficiencies. Based on a very complete data set of Québec hospitals, we find that significant inefficiencies of up to 17% ($700 CAN million) could have been saved through improved performance. Postestimation analyses that include qualitative measures of care suggest that differences in performance are attributable to differences in management or unobservable quality of care rather than patient case mix.  相似文献

税后资本平均产出的高低对私人部门投资决策产生重要影响,但是我国自1994年分税制改革以来,税后资本平均产出处于不断下降趋势,与此同时,财政支出规模呈不断扩大趋势。本文在财政支出解决市场拥挤框架下分析了财政支出对税后资本平均产出的影响,在理论分析中,说明财政通过增加支出缓解市场拥挤来影响税后资本平均产出,其影响程度由税率、财政支出的产出弹性、市场拥挤程度决定。在实证分析中,计量检验了世界范围内和中国地方政府财政支出对税后资本平均产出的影响,并结合现实对计量结果给予解释。  相似文献

城乡规划代表公共利益,物权法保护物权人的合法权益;城乡规划及其管理代表一种调整和规范土地及地上建筑物等不动产物权的设立、行使的公共行政权力,物权法赋予了物权人对其不动产相关物权享有直接支配、排他性干涉的权力;在城乡规划及其管理工作方面,如何平衡上述两种权力?本文从城乡规划及其管理的主要环节--编制、实施、监督检查、批后管理四方面做出了阐释.  相似文献

Rights are very important concepts in everyday life. And they are especially important to participants in organizations. Yet, our theories of organization and management have largely ignored rights — stressing, instead, other concepts, such as goals, roles, etc. This article describes the historical significance of rights and their relevance in understanding social behavior. The advantages of a right-based organizational theory (versus traditional goal-based theories) are discussed.This article draws on the author's forthcoming book,A Social-Contract Theory of Organizations (University of Notre Dame Press, 1988).  相似文献

This study has 3 objectives: to develop a scale to measure preferences for involvement in management (PIM), to examine if PIM are related to work values (altruism, pride in craftsmanship, collectivism, and individualism), and to examine if PIM are affected by a bundle of work values. Data are taken from 749 participants to develop a psychometrically appealing scale for measuring PIM. Using the universalistic perspective, we predict a positive relationship between PIM and altruism, pride in craftsmanship, and collectivism, and a negative relationship between PIM and individualism. Using the synergistic perspective, we hypothesized that PIM are likely to be positively affected by a bundle of work values. Our results support the universalistic perspective because PIM are positively related to altruism, pride in craftsmanship, and collectivism, and negatively related to individualism. Our results did not support the synergistic perspective. In the final section of the paper, we outlined the implications of our results for organizational practice and public policy.  相似文献

Subsidised employment is an important tool of active labour market policies to improve the reemployment chances of the unemployed. Using unusually informative individual data from administrative records, we investigate the effects of two different schemes of subsidised temporary employment implemented in Switzerland: non-profit employment programmes (EP) and a subsidy for temporary jobs (TEMP) in private and public firms. Econometric matching methods show that TEMP is more successful than EP in getting the unemployed back to work. Compared to not participating in any programme, EP and TEMP are ineffective for unemployed who find jobs easily anyway or have a short unemployment spell. For potential and actual long-term unemployed, both programmes may have positive effects, but the effect of TEMP is larger.  相似文献

文章以沪深两市55家商业上市公司为样本,对股权结构与公司业绩的关系进行回归分析。结论表明:商业上市公司国有股比例对公司业绩并没有显著的影响,但法人股比例与公司业绩显著正相关,流通股比例与公司业绩显著负相关。同时,第一大股东持股比例与公司业绩没有显著关系,但前五大股东持股比例与公司业绩显著正相关;另外,第一大股东的控制能力对公司业绩有显著的负面影响。  相似文献

We investigate the role of international trade and proximity to war in international stock markets during the invasion of Ukraine by employing DiD designs and panel data comprising 70 stock markets. We find that differences in trade exposure to warring countries (trade effect) have a substantial and negative impact on non-European equity markets but are irrelevant for European markets. In contrast, differences in the distance to warring countries (proximity effect) have a significant and negative impact on European markets but have no bearing on non-European markets. We find that the relevance of rent from mineral, natural gas, and oil resources and the relevance of metals, ores, and fuels in exports operate as mitigators of the trade effect. Our paper provides valuable empirical evidence regarding the importance of mitigating the vulnerability of financial markets to international trade when a major war breaks out.  相似文献
