We investigate the informational efficiency of mutual fund performancefor the period 1965-84. Results are shown to be sensitive tothe measurement of performance chosen. We find that returnson S&P stocks, returns on non-S&P stocks, and returnson bonds are significant factors in performance assessment.Once we correct for the impact of non-S&P assets on mutualfund returns, we find that mutual funds do not earn returnsthat justify their information acquisition costs. This is consistentwith results for prior periods.  相似文献

This study provides further empirical evidence on incentives for Australian firms to voluntarily report segment information. Various economic reasons why firms may elect to present segment information have been hypothesised in previous research. Bradbury [1992] and McKinnon and Dalimunthe [1993] found firm size, minority interest and industry membership as significant identifiable characteristics motivating voluntary segmental disclosure. Variables found to be insignificant in Bradbury [1992] which were not examined by McKinnon and Dalimunthe [1993] are tested in this paper. Hypotheses relating to size, financial leverage, assets-in-place, earnings volatility, ownership diffusion, outside equity (minority) interest, overseas association as well as diverse and mining and oil classification hypotheses are empirically examined. Univariate tests and multivariate logit analysis suggest that for a extensive sample of diversified firms, voluntary segment disclosure is significantly related to size, leverage and involvement in mining or oil activities.  相似文献

This paper employs Greenberg'sTheory of Social Situations to explain the variation of sharecropping contracts across economies as a function of social norms that satisfy von Neumann-Morgenstern stability. We demonstrate that equal division and core outcomes are jointly possible when bargaining is unrestricted. By contrast, when the landlord acts as a monopsonist, core outcomes are the only possible social norm. In addition, if the presence of an outside wage is recognized, core and equal division norms may coincide.  相似文献

We investigate share price reactions to announcements of dividends payable in the common stock of corporations different from the issuing firm. We find that firms that declare these dividends (typically investment companies) experience positive abnormal returns upon announcement. We also find that such dividends are more likely to be declared when the shares to be distributed have peaked in value. Consistent with this finding, we document negative announcement-period abnormal returns for firms having their shares distributed. Additional tests reveal that prices respond more negatively when the information signal is strongest, when outside ownership is more dispersed, and when management is more entrenched.  相似文献

Abstract. The labor turnover rate in Japan is less than half the US level. A small-scale survey of companies that operate in both Japan and the USA was conducted to examine reasons for the discrepancy. The main findings are that Japanese human resource policies, including steep seniority-earnings profiles, extensive fringe benefits, participatory management, and a reluctance to recruit experienced workers from other firms, contribute to the lower Japanese turnover rate. Additionally, workers of Japanese descent in the USA have a somewhat lower labor turnover rate than other Americans, suggesting some role for cultural differences.  相似文献

A theoretical model of state tax structure implies that revenue enhancement due to the introduction of casino gambling is less likely in states where incomes taxes do not exist and where casino tax rates are lower than the corresponding tax rates on sales taxable and excise taxable goods. Further, it is clear that casino gambling is likely to adversely impact lottery tax revenues earmarked for education. Due to the cross-price effects of gambling, tax revenues will likely decline in states that introduce nontaxable casino gambling on Indian reservations. In the longer term, as casino gambling proliferates increasing competition among states, there will be negative revenue consequences due to fewer tourism and employment dollars.  相似文献

With more than 40% of the urban population of the Third World living in informal settlements, quasi- and extralegal adaptations have been utilized to appropriate land for housing. The most direct of these — squatting — has its inherent risks, however, for those who wish to improve their dwellings. Research has shown that house consolidation is more a function of resident perceptions than of strict legal categorization. This paper reports how such perceptions have triggered a greater rate of house consolidation among Javanese cemetery squatters than that in an adjoining area with formal land tenure.  相似文献

Water Resources in the Asia-Pacific Region: Managing Scarcity   总被引:1,自引:0,他引:1  
Irrigation, together with improved crop varieties and substantial growth in fertiliser use in the late 1960s through the early 1980s, was a key factor in stimulating strong agricultural growth in much of the Asia-Pacific region. New sources of water are increasingly expensive to exploit, but irrigation continues to be a major catalyst for agricultural growth. In the face of increasing degradation, the maintenance of the water resource base must be a high priority policy objective. This paper reviews the management of water resources in the Asia-Pacific region, for countries with significant irrigated area: Cambodia, China, Indonesia, Korea-DPR, Republic of Korea, Laos, Malaysia, Mongolia, Myanmar, Philippines, Thailand and Vietnam.  相似文献
