Henry George and Economic Intervention

A bstract . Henry George , the 19th century American economist and social philosopher , was recognized as an individualist. His Single Tax on the value of land and all natural resources would socialize the rent while preserving private ownership and use. His positions on industrial monoplies were not so clear. He urged the abolition of all special privileges but did not see clearly that this would end many such monopolies. He understated the effects of the single land value tax and the abolition of special privileges; they would go a long way toward ending all industrial monopolies.

A comparison of the technical efficiencies of health districts and hospitals in Botswana

An attempt is made here to construct and present relative efficiency indices for the services rendered by health districts and specific hospitals in Botswana, using Stochastic Frontier Regression analysis and Data Envelopment Analysis. The analysis indicated that three districts - Kweneng East, Kgalagadi and Boteti - have efficiency scores below the optimum level. Among the 13 hospitals considered, Tsabong Primary Hospital was found to have an efficiency score of less than one. Since the health services involve a number of factors, these indices ought to serve as indicators for further scrutiny of those units (health districts and hospitals) that fall below the optimum efficiency level. The data used for the analysis are from the published material by the Central Statistics Office, Botswana for the year 1997. Health is considered one of the major concerns of the government of Botswana. As a consequence, the authors feel that this study will be useful to policy makers and health planners in giving them some kind of relative ranking among health districts and hospitals.     

Applying marketing strategy to private source grantsmanship

As funding opportunities for research and program development continue to decrease, faculty and administrators must understand, to be competitive, that a large part of grantsmanship is marketing. This paper discusses the rationale for seeking grant support, how faculty can identify potential funding sources, and how to target the final submission of the proposal. Understanding these topics will assist faculty in developing those skills required for competing successfully in an increasingly competitive environment.     

Efficiency of the office properties market

This paper reports the results of an efficient markets test of the Dallas-Fort Worth office properties market. ARIMA models using a comprehensive data set did not produce superior forecasts. The results provide further evidence of the efficiency of real estate markets.

More Powerful Portfolio Approaches to Regressing Abnormal Returns on Firm-Specific Variables for Cross-Sectional Studies

OLS regression ignores both heteroscedasticity and cross-correlations of abnormal returns; therefore, tests of regression coefficients are weak and biased. A Portfolio OLS (POLS) regression accounts for correlations and ensures unbiasedness of tests, but does not improve their power. We propose Portfolio Weighted Least Squares (PWLS) and Portfolio Constant Correlation Model (PCCM) regressions to improve the power. Both utilize the heteroscedasticity of abnormal returns in estimating the coefficients; PWLS ignores the correlations, while PCCM uses intra-and inter-industry correlations. Simulation results show that both lead to more powerful tests of regression coefficients than POLS.     

A macro model of change in specialty and spatial distribution of physicians in Canada, 1971-1981.

Most studies on physician distribution have examined static relationships involving the influence of such factors as socio-economic status. This study employs a causal model to study change in physician ratios (general practitioners and family physicians, and specialists) between 1971 and 1981 as a function of change in hospital bed ratios, population size, age distribution, educational attainment of the population, population "native", owner-occupied dwellings, and geographic proximity to the nearest metropolitan area, using physician data for 189 Canadian census divisions. The results, derived from LISREL VI analyses, indicate that specialists experienced increases in their supply in higher socio-economic status areas and in those areas losing general practitioners and family physicians (from 1971 to 1981). General practitioners and family physicians appear to have moved into areas with a relatively low percentage of owner-occupied dwellings and areas where a large percentage of the population is "native". Both groups of physicians appear to have increased in areas where there were increases in hospital facilities over the decade. The study confirms the known association between the two physician groups; that is, general practitioners and family physicians increased in areas gaining specialists and specialists increased in areas where considerable decreases in general practitioners and family physicians were occurring. Findings are discussed in terms of implications for physician manpower planning.
