A multivariate model of the process by which managers decide to release public forecasts of their firms' earnings is developed, based on factors that are hypothesized to affect the demand for and the willingness to supply such forecasts. We test the model on data from a comprehensive sample of earnings forecasts, and find support for our hypotheses about the likely joint influence of those factors. Larger firm size, greater leverage, higher and more stable earnings rates and less rapid growth rates are found to be associated with an increased propensity for management to provide earnings forecasts for their firms. 相似文献

This paper incorporates an ecosystem model into a model of a simple economy. The decisionmaking agents in the ecosystem are individual organisms aggregated to the species level. A species may provide utility directly to humans, or it may provide utility indirectly because it is used either as a raw material in goods fabrication or as sustenance for other species. We describe a comparative static equilibrium of the ecosystem where species' demands for other species are equal to the supplies of those other species, and energy is conserved. The ecosystem is then embedded in the economy so that the effects of human intervention can be traced through both the ecosystem and the economy. Human intervention creates ecosystem externalities such that ecosystem equilibria are shifted and the new equilibria affect the utility or the production processes of other humans. This framework allows us to describe in principle which ecosystem services can be efficiently usurped by humans, which waste flows can be efficiently allowed into ecosystems, and which ecosystem organisms and physical attributes can be efficiently maintained. 相似文献

Actual, not potential, relatedness determines the results of diversification strategies. An external examination of a firm's businesses, products, markets and technologies permits an assessment of potential relatedness among its various businesses. Potential relatedness is, however, often not realized. Also, relatedness may be externally invisible. Hence, actual relatedness may diverge from externally measured potential relatedness. This paper provides evidence suggesting that measures of corporate diversification strategy based on internal data differ significantly from those based on externally available data. 相似文献

Competitive decision making: Two and a half frames 总被引:1,自引:1,他引:0
We argue that the study of competitive decision making has been heavily influenced by the frames of reference that are adopted by researchers. The dominant economic frame and the emergent behavioral frame describe largely separate phenomena and have little overlap. Drawing from examples of learning in games and markets, we show how each of these frames falls short of capturing some interesting elements in competitive decisions. We then describe how a coevolutionary perspective may be emerging as an integrative paradigm for the study of competitive decisions.This paper was prepared for the conference, Understanding Competitive Decision Making. Comments by the participants of that conference and Paul Shoemaker are gratefully acknowledged, as are discussions with Colin Camerer, Eldar Shafir, and Sharoni Shafir. 相似文献

This article aims to bridge the gap between an oriental culture and a western approach to management concepts and practice with a view to exploring a culturally fit style of management for China. Comparisons are drawn between the teachings of early Chinese philosophers and scholars with those of their western counterparts. It is envisaged that hidden links may be eventually found so that management as a universal concept with cultural variations may be the trend in the nineties and beyond. 相似文献

This article finds that gender differences in on-the-job training significantly affect the male/female wage gap. First, we find that previously trained workers exhibit larger cumulative wage gains during their current training. Thus, a substantial portion of the gender wage gap results from the fact that women have little prior training relative to men. Second, a significant amount of the observed male/female wage differential is explained by less female acquisition of current training. Gender differences in workplace promotion and training practices help explain why women accumulate less training than men. Both of these sources of gender differences have lessened from 1976 to 1985, which has led to a narrowing of the male/female wage gap. 相似文献

This article provides estimates of the effect of statutory severance pay and notice on four labor market outcome indicators, closely following Lazear (1990) but correcting for errors in his dependent variables and covariates. Although we corroborate the directional influence of severance pay for three of the indicators, there is little to suggest that its contribution to rising unemployment is material. Also contrary to Lazear, longer notice appears to be associated with broadly favorable outcomes. 相似文献

This paper analyzes the reasons for Japanese/U.S. collaborations in the biotechnology industry, and considers the question of whether such alliances pose a threat to the North American industry. Japan's technological competitiveness in biotechnology is examined in terms of its strengths and perceived weaknesses. Ways in which Japan is attempting to overcome these weaknesses are identified. As well, the strengths and weaknesses of the North American biotechnology industry are assessed. The paper concludes with recommendations for government and R&D managers on how to preserve U.S. competitiveness. R&D managers must keep abreast of their techno-global competitive environments. While organizations can enter into alliances to improve their competitiveness they must be aware of the dangers of collaboration, and to benefit from their alliances they must enhance their organizational learning. Organizations must be aware of the pitfalls of alliance formation, and any alliance must be viewed in its national context. Last, but not least, managers must be more effective in their management of the processes of technological innovation. 相似文献

Opponents of U.S. and Canadian strike replacement legislation contend that restricting the use of strike replacements significantly alters bargaining power and increases strike activity. This article uses data on Canadian manufacturing collective-bargaining agreements to investigate these hypotheses. Although a general ban on strike replacements is found to be associated with longer strikes, little evidence is found to suggest that banning permanent strike replacements significantly influences strike incidence, strike duration, or negotiated wages. 相似文献
