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. 相似文献

The decision of credit unions in the United States to adopt transactional web-based services is consistent with profit-maximization behavior. Credit unions adopt transactional internet banking services when they provide a higher proportion of consumer loans and when there is increased competition from other financial institutions. They adopt transactional internet banking to attract new customers. The larger the credit union the higher the probability of adoption of transactional internet banking. The probability of adoption of transactional banking is directly related to credit unions’ efficiency and indirectly related to loan delinquencies. We also find that the probability of credit unions offering transactional internet banking is positively related to the percentage of the young population in the counties where credit unions are located. 相似文献

I re-examine the association between diverse investor beliefs and stock prices within the context of an imperfect competition model. The relationship is ambiguous because of several different effects of a change in diversity in investor beliefs. This has implications for empirical design and explains why 40 years of evidence on this association is inconclusive. 相似文献

This research examines the predictive ability of direct method cash flow information for firms that use the direct method in their cash flow statements. We use cross sectional and pooled time series regressions to predict operating cash flow data and assess relative predictive ability. Principal findings are: (1) past period direct method cash flow data predict future operating cash flow better than indirect method cash flow data; (2) past period direct method gross operating cash flows predict future net operating cash flow better than past period net operating cash flow; (3) measurement error exists in estimates of direct method operating cash flows from other financial statement data; (4) past operating cash flows predict future operating cash flows better than earnings and accruals. 相似文献

In this paper, we use plant-level data from two Indian industries, namely, electrical machinery and textiles, to examine the empirical relationship between structural reforms like abandonment of entry restrictions to the product market, competition and firm-level productivity and efficiency. These industries have faced different sets of policies since Independence but both were restricted in the adoption of technology and in the development of optimal scales of production. They also belonged to the first set of industries that benefited from the liberalization process started in the 1980s. Our results suggest that both the industries have improved their efficiency and scales of operation by the turn of the century. However, the process of adjustment seems to have been worked out more fully for electrical machinery. We also find evidence of spatial fragmentation of the market as late as 2000–2001. Gains in labour productivity were much more evident in states that either have a strong history of industrial activity or those that have experienced significant improvements in business environment since 1991. 相似文献

We estimate a translog production function based on data from a Japanese automobile plant in the Midwest where output is determined by capital and different supervisory time inputs. We fit a model which allows for heteroskedastic errors, where this heteroskedasticity is a function of various variables affecting perceived target severity. We find that while, as expected, capital inputs are important, each supervisory time input is also significant in this capital-intensive industry. Linear homogeneity in these inputs is rejected. We find evidence of asymmetry in substitution among different components of supervisory time. This asymmetry has implications for the design and allocation of supervisory tasks. © 1997 John Wiley & Sons, Ltd. 相似文献

This article uses the extended case method to explore senior executives’ corporate finance decisions. We quantified firm’s finance practices using a mail survey, and then – to resolve puzzles in managers’ decision processes – conducted face‐to‐face interviews with chief finance officers of large listed firms. The interviews identified six themes as consistent influences on finance decisions: pressures imposed by clienteles; constraints on resources; risk management; heuristics; real options; and sustainability. We conclude that managers are logical and rational in their decisions, but employ a wider range of criteria than assumed in conventional finance theories. 相似文献
