By definition profit refers to the difference between revenue and expenses. In for-profit organizations profit or surplus gives a return to the owners of the company and serves as a source of financing for capital acquisitions and working capital. Nonprofit organizations, which are not allowed a surplus, don't suffer on the first count because they have no owners. But they do suffer on the second count because, if expected to grow, they need to finance asset replacement and growth. In these days when funds for long-term debt are becoming scarcer, this author asserts, the need for regulators to allow 'nonprofits' to keep a surplus is increasing. In this article, he argues for a surplus and then discusses how managers and regulators can determine how much a nonprofit organization should be allowed. He presents a combination of a modified version of the return-on-asset pricing model used in for-profit organizations and a model for assessing working capital needs associated with growth.  相似文献

The operating context of South Korean human resource management (HRM) has undergone radical shifts since we wrote our first piece in 1997 for a similar collection to this. This has undoubtedly influenced the practice of HRM. Therefore, the focus of this piece is to compare the current situation with the past and delineate the amount and type of such change vis-à-vis continuity in HRM. The contextual factors and issues, political and economic background, labour market situation, the 1997 Asian financial crisis and ramifications, are analysed. Then future possible scenarios and key issues are outlined.  相似文献

We use the daily opening and closing prices of eighteen dually-listed Hong Kong companies to investigate the transfer of pricing information between the Stock Exchange of Hong Kong (SEHK) and the London Stock Exchange (LSE). Evidence shows that (1) SEHK overnight returns respond significantly to change in LSE intraday returns, but the transmission process is not completed at the opening of the SEHK; (2) LSE overnight returns respond significantly to changes in SEHK intraday returns, but the transmission process is not completed at the opening of the LSE, either; (3) the impact is stronger moving from the LSE to the SEHK. This evidence indicates that information transfer runs in both directions and that most of the transmitted information continues to be processed throughout the following trading day (JEL G15).  相似文献

United States input-output accounts identify and measure the interrelationships between the various industries in the United States economy. However, these accounts do not identify nonprofit activities from their for-profit counterparts in the service-producing sector. This paper, prepared by Gabriel Rudney and Paula Young, presents the methodology and summary data produced by disaggregating the service-producing industries to identify separately nonprofit activities.
The input-output accounts for 1977 produced in this study include 107 industries, but in this paper the results are summarized into 14 industries showing only nonprofit and for-profit components. The GNP and total outputs in this study are consistent with the revised input-output accounts for 1977 prepared by the U.S. Department of Commerce, Bureau of Economic Analysis.  相似文献

The stochastic production frontier approach is used to study the effects of education on agricultural efficiency for a cross-section of 'early-stage' farms from Guanghan County, Sichuan Province, China. Education for farm families in rural China is multifaceted with a combination of formal education, intragenerational transfer of knowledge within the home, and agricultural extension services. Since our survey data span two different years with markedly different policy environments, we are able to examine not only which aspects of education affect agricultural efficiency, but also whether or not the policy environment matters. We find limited evidence that in a policy environment that is conducive to agriculture, formal education provides positive returns in agriculture. Furthermore, general education may provide greater returns than the more targeted extension services.  相似文献

This paper examines the influence of foreign factor prices andinternational corporate taxation on fixed investment in theUK manufacturing sector. The evidence suggests that factor pricesaffect fixed investment in the UK through their influence oninternational competitiveness rather than the factor mix decision.There also appears to be a significant effect of tax competitivenesson the rate of investment. Empirical evidence suggests thatpolicy to increase investment be aimed at reducing the averagerate rather than the marginal rate of corporation tax.  相似文献

This paper examines the relationship between sources of family income and household expenditure on private, after‐school education for children in secondary schools in Korea in the context of educational ‘credentialism’, which values evidence of college education highly. Data from a survey of 514 parents of secondary school students are used. Estimated ordinary least squares coefficients indicate that the wife's income, but not the husband's, was positively associated with the amount of spending on children's education at private, after‐school programmes. This finding suggests that some married women with children in Korea seek employment in order to earn the money needed for their children's private, after‐school education.  相似文献

Just as standards wars over formats had characterized VCRs upon introduction to the market, the next‐generation DVD standards war between Blu‐Ray and HD‐DVD lasted 6 years before Blu‐Ray won the contest. Beginning with stated preference data drawn from a structured conjoint survey conducted before Blu‐Ray became the de facto standard of the next‐generation DVD format, we estimate consumer preferences on digital video players. A Bayesian mixed‐logit model is used and market share simulations are conducted under various scenarios based on the estimated parameters from Bayesian mixed‐logit model to surmise the future South Korean digital video‐player market. Results indicate that consumers feel that network size and title availability are more important than hardware‐related facets of the product, such as definition and storage capacity. The level of title availability and price of the Blu‐Ray player for Blu‐Ray's dominance over DVD will dramatically vary by the penetration rate of DVD players.  相似文献

The within‐group estimator (same as the least squares dummy variable estimator) of the dominant root in dynamic panel regression is known to be biased downwards. This article studies recursive mean adjustment (RMA) as a strategy to reduce this bias for AR(p) processes that may exhibit cross‐sectional dependence. Asymptotic properties for N,T→∞ jointly are developed. When ( log 2T)(N/T)→ζ, where ζ is a non‐zero constant, the estimator exhibits nearly negligible inconsistency. Simulation experiments demonstrate that the RMA estimator performs well in terms of reducing bias, variance and mean square error both when error terms are cross‐sectionally independent and when they are not. RMA dominates comparable estimators when T is small and/or when the underlying process is persistent.  相似文献
