This paper analyzes a point in-point out inventory investment under price uncertainty. The optimal quantity is determined by maximizing the expected value of the investor's risk preference function, which is a function of profit. Using an exponential risk preference function, the adjustment in the optimal quantity stemming from a change in the interest rate is investigated. The main conclusion is that the sign of the adjustment depends both on how profit is expressed and on the type of price distribution applied. Contrary to what is assumed in conventional managerial control practices, a rise in the interest rate might lead to an increase in the optimal quantity when present value serves as a measure of profit. 相似文献

Human capital raises rural incomes, but this effect is swamped by higher returns to human capital in urban markets. This leads to "brain drain" from rural areas. Populations grow more rapidly in rural counties that have a diversified employment base. Farm population grows faster (or declines more slowly) in counties with relatively high farm income, and nonfarm populations grow faster in counties with relatively high nonfarm income. However, higher farm incomes lead to slower nonfarm population growth and vice versa. Rural county government services financed by local taxes or debt have neutral or negative effects on population growth. 相似文献

Managerial Equity Ownership and the Demand for Outside Directors 总被引:1,自引:0,他引:1
This paper examines the linkage between the use of outside directors and managerial ownership. We conjecture there are two linkages: the standard incentive‐alignment demand for monitoring when managers own little stock and an entrenchment‐amelioration demand when managerial stock ownership is high. As a consequence, we predict the association between managerial ownership and board composition will be nonlinear (U‐shaped if the entrenchment effect is sufficiently pronounced). Using UK data, we find that both quadratic and logarithmic models outperform the simple linear relationship assumed in prior research and that the substitution between managerial ownership and board composition is stronger than hitherto supposed. 相似文献

Estimating the Size of a Criminal Population from Police Records Using the Truncated Poisson Regression Model 总被引:1,自引:0,他引:1

The truncated Poisson regression model is used to arrive at point and interval estimates of the size of two offender populations, i.e. drunk drivers and persons who illegally possess firearms. The dependent capture–recapture variables are constructed from Dutch police records and are counts of individual arrests for both violations. The population size estimates are derived assuming that each count is a realization of a Poisson distribution, and that the Poisson parameters are related to covariates through the truncated Poisson regression model. These assumptions are discussed in detail, and the tenability of the second assumption is assessed by evaluating the marginal residuals and performing tests on overdispersion. For the firearms example, the second assumption seems to hold well, but for the drunk drivers example there is some overdispersion. It is concluded that the method is useful, provided it is used with care. 相似文献

Charity Technology Trust (CTT) is one of a new breed of philanthropic initiatives aimed at helping UK charities become more efficient by better use of technology. Its founder believes that charities are ideally placed to benefit from the reduced costs and shared benefits of jointly developed strategies and fundraising, communications and data management tools. CTT was formed to catalyse a move in this direction from the major UK fundraising charities and is supported by the personal philanthropic contributions of its trustees—a group of successful businessmen. The challenge for such a new organisation with a new idea is considerable, but after 18 months CTT is working with 27 of the top 100 UK charities on projects from online raffles through e‐mail communications to IT strategy.

This article presents the results of a survey of professors in accounting departments in Australia. Professors ranked Australian accounting departments on a variety of research, teaching and staffing attributes, on contributions to the accounting profession and provided an overall ranking of the departments. Overall rankings placed the University of Queensland and the University of New South Wales a close first and second, followed by the University of Sydney, the University of Melbourne, the University of Western Australia, and Monash University. Analysis of the separate sub-dimensions of performance shows that it is variations in respondents' perceptions of research-related performance of departments which accounts for variation in the overall ranking. We also asked the professors for their views on several issues facing accounting educators and those who recruit accounting graduates. Most believed that there should be more breadth in undergraduate accounting courses than is currently the case. However, most felt that recruiters would prefer degree structures to remain as they are. There was overwhelming consensus that it was reasonable to expect ethics to be taught in accounting programs; that the Australian Securities Commission should not replace corporate management in the appointment of auditors; and that accounting standards should not be written to force very conservative depictions of profitability and financial position. There was disparity of opinions on whether auditors ought to be expected to foreshadow financial distress; whether the audit role should be expanded to explicitly embrace fraud detection; and whether financial reports should be understandable to the lay person. 相似文献

This paper reports an empirical examination of independent expert reports in takeover bids using the 170 reports that were issued in the 364 cash-based bids that occurred between January 1988 and December 1991. It was found that bid premia offered in takeover bids where an expert's report was issued were not significantly lower than bid premia in other bids. This may be attributable to independent experts acting as a countervailing influence on bidders holding a superior pre-bid bargaining position. Next, some dimensions of the “fair and reasonable” criterion that experts are required to use are examined. These are the single-test and dual-test interpretations of the phrase, the relation between offer price, market price and the expert's valuation of the target, the cost and length of expert's reports and, finally, the influence an expert has on the outcome of a bid. 相似文献
