We study time-consistent labour and capital income linear taxationusing an infinite-horizon overlapping-generations model of asmall open economy. Individuals have different productivitiesand the government intervenes for purely redistributive purposes.The study of time-consistent taxation requires the introductionof borrowing restrictions in the economy. We characterize thetime-consistent solution and consider alternative solutionsbased on a simple tax rule. We demonstrate the existence andthe uniqueness of the time-consistent solution using a log-linearutility function. We provide numerical comparisons between time-consistentand time-inconsistent linear taxation: the importance of beingable to make commitment decreases when the differences betweenindividuals increase. 相似文献

Using data from the UK Census of Production, including foreign ownership data, and information from UK industry input-output tables, this paper examines whether the intensity of transactions linkages between foreign and domestic firms affects productivity growth in domestic manufacturing industries. The implications of the findings for policies promoting linkages between multinational and domestic firms in the UK economy are outlined. 相似文献

The traditional rationale for differencing time series data is to attain stationarity. For a nearly non-stationary first-order autoregressive process—AR (1) with positive slope parameter near unity—we were led to a complementary rationale. If one suspects near non-stationarity of the AR (1) process, if the sample size is ‘small’ or ‘moderate’, and if good one-step-ahead prediction performance is the goal, then it is wise to difference the data and treat the differences as observations on a stationary AR (1) process. Estimation by Ordinary Least Squares then appears to be at least as satisfactory as nonlinear least squares. Use of differencing for an already stationary process can be motivated by Bayesian concepts: differencing can be viewed as an easy way to incorporate non-diffuse prior judgement—that the process is nearly non-stationary—into one's analysis. Random walks and near random walks are often encountered in economics. Unless one's sample size is large, the same statistical analyses apply to either. 相似文献

Several recent studies point to the value of using combinations of biochemical markers for the identification of alcohol abuse. The Early Detection of Alcohol Consumption (EDAC) test uses a statistical method that combines the results of several routine laboratory tests to form a metabolic fingerprint for each subject. In this study, we evaluated the use of the EDAC test as a screening tool to assess heavy drinking in insurance applicants. The EDAC was calculated by linear discriminate function analysis using the results of 14 routine tests including liver enzymes, lipids, proteins, and blood sugars. We collected and analyzed 1680 random samples at Heritage Laboratories (Olathe, Kan). Alcohol Detection Services (Brookfield, Wis) and Millennium Strategies (Madison, Wis) collaborated in the data analysis and interpretation of laboratory tests results. Ninety-three percent of applicants showed a negative EDAC test. The 7% (n = 134) who screened positive for the EDAC test were then reflexed to carbohydrate deficient transferin (CDT) and whole blood associated acetaldehyde (WBAA). Sixteen percent (22/134) showed a positive confirmatory test. Among these 16% of subjects, 41% (9/22) showed no elevations in liver enzymes or HDL-C results. Four of these subjects were among the top one third with the highest elevations for the CDT test in the entire group and one of them was positive for both the CDT and WBAA tests. These results suggest that the EDAC screen may provide an efficient alternative screening tool for the identification of heavy alcohol consumption not HBA as it identifies applicants with both normal or abnormal liver enzymes and HDL-C. 相似文献

This article tests the view (derived from Hicks and Patinkin)that non-market clearance may be caused by slow adjustment (processrigidity). There are models where market-rationing ispresent and derives from some form of rigidity, but this rigiditycannot be considered as process rigidity. It is similarly possibleto accommodate the idea of process rigidity within the Marshallianresearch programme. What is missing is that market-rationingmight be its corollary. The reason such a causal link is oftenbelieved to exist lies in a generic use of the concept of rigidity,used to designate alternative and incompatible phenomena: exogenousend-state rigidity and equilibrium end-state rigidity,as well as process rigidity. It is true that these first twoforms of rigidity create market rationing. The belief that slowadjustment also generates market rationing results from theunwarranted extension to process rigidity of conclusions whichare only valid for the first two. 相似文献

Corporate social performance, financial performance and institutional ownership in Canadian firms 总被引:1,自引:0,他引:1
This study examines the relationship of corporate social performance (CSP) to financial performance (FP) and institutional ownership. We perform our empirical analyses on a large-sample of publicly held Canadian firms and use a novel independent measure of CSP. Based on tests utilizing four years of panel data, we found no significant relationship between a composite measure of firms’ CSP and FP. However, we found significant relationships between individual measures of firms’ CSP regarding environmental and international activities and FP. Our findings indicate a significant relationship between firms’ composite CSP measure and the number of institutions investing in firms’ stock. In addition, we found significant relationships between firms’ CSP ratings regarding their international activities and product quality and the number of institutions investing in firms’ stock. These findings, while subject to the limitations inherent in the use of specific CSP measures, provide mixed support for the business case for CSP. 相似文献

The role and potential contribution of a positive lens to the design of systems and organizations is the focus of this introductory essay. The positive lens refers to a perspective in the social sciences that emphasizes the capacity of people and organizations to construct better work environments, customer experiences and socio-technical systems through a positive discourse. Joining a positive lens on organizing with the transformative power of design thinking opens new horizons and uncovers previously overlooked possibilities for creating organizational and social well-being. This volume aims to introduce design with a positive lens into the research on information systems and organizations and to explore its potential value. 相似文献
