A risk-averse US investor adjusts the shares of a portfolio of short-term nominal domestic and foreign assets to maximize expected utility. The optimal strategy is to respond immediately to all new information which arrives weekly. We develop a model to estimate the cost of optimizing less frequently and find that it is generally very small. For example, if the investor adjusts portfolio shares every three months, an average expected utility loss of 0.16 per cent p.a. is incurred. Hence, slight opportunity costs of frequent optimization may outweigh the benefits. This result may help explain forward discount bias.  相似文献

The marketing environment in the 21st century promises to be knowledge rich and very turbulent. The classic, vertically integrated, multidivisional organization, so successful in the 20th century, is unlikely to survive in such an environment. The evidence indicates it will be replaced by new forms of network organization consisting of large numbers of functionally specialized firms tied together in cooperative exchange relationships. This article explores the characteristics of four types of network organization that may represent prototypes of the dominant organizations of the next century. These include the internal market network, the vertical market network, the intermarket network, and the opportunity network. The economic rationale and the types of coordination and control mechanisms driving network organizations are very distinct from those studied under the current exchange or dyadic paradigm. This article analyses the kinds of changes involved in key variables and their meanings in moving from a dyadic view of exchange to a network view.

It is generally claimed that brand names are a corporate asset with an economic value that creates wealth for a firm’s shareholders. However, the scholarly literature has neither provided a comprehensive theoretical basis for this claim nor documented an empirical relationship between brand value and shareholder value. This exploratory study describes a rationale for, and documents, the statistical strength and functional form of a brand value-shareholder value relationship for publicly held consumer goods companies in the United States. A theoretical argument supportive of a positive relationship between a firm’s accumulated brand value and market-to-book (M/B) ratio was empirically validated. However, even though firms with higher accumulated brand values have higher M/B ratios, the functional form of the relationship was found to be concave with decreasing returns to scale. Theoretical and managerial implications of these findings are outlined, as well as study limitations and directions for future research. Roger A.

This paper compares the number of consumer information cues found in television advertisements in three countries: Australia, Ecuador, and the United States. Earlier studies conducted by Resnick and Stern in the United States and Dowling in Australia were replicated in Ecuador. Content analysis of 108 Ecuadorian television advertisements evaluated the number and types of information cues in each commercial. Results indicate that a much greater proportion of Ecuadorian television commercials contain consumer information cues than those broadcast in the other two countries. The explanation suggested for this observation is that Ecuador, due to its level of economic development, has many more products in the introductory stages of the product life cycle. This situation, in turn, requires more extensive communication of consumer information to market the products effectively. This finding implies an additional dimension, information content level, which must be considered when adapting international campaigns to conditions in developing countries.  相似文献

Although the issue of regulatory devolution has received muchscholarly scrutiny, rigorous empirical studies of its effectson important policy outcomes are scarce. This article exploresthe effects of partial regulatory devolution in the occupationalsafety arena by exploiting a unique historical anomaly wherebysome US states enforce protective labor regulations that areenforced elsewhere by the federal Occupational Safety and HealthAdministration. Analyzing data from the construction industry,this article contains several important findings. First, stateinspectors use traditional enforcement tools more sparinglythan their federal counterparts, typically citing fewer violationsand collecting lower fines per violation. Second, although federalenforcement significantly lowers the estimated frequency ofnonfatal construction injuries, it also predicts a significantincrease in occupational fatalities. I suggest that althoughhigher underreporting of nonfatal injuries in federally regulatedstates could explain this puzzling finding, it is equally possiblethat different regulatory styles have different "comparativeadvantages" in deterring nonfatal injuries on one hand and occupationalfatalities on the other.

The United States faces a long-run fiscal imbalance because of rapid projected growth in Social Security, Medicare, and Medicaid spending. The policy response to the imbalance will be shaped by four long-term fiscal realities. First, revenue will rise as a share of GDP. Second, entitlement spending will be reduced, relative to current policies. Third, the middle class, broadly defined, will bear much of the burden of addressing the fiscal imbalance. Fourth, consumption taxation is likely to become a significant part of the federal tax system, probably through the partial replacement of the income tax by a value added tax.  相似文献

Negotiation is an essential skill for personal well-being and professional success, a skill that begins with identifying and acting on one's wants and needs. Many individuals, however, lack the confidence, motivation, or training to simply ask for what they want in certain situations; for example, when negotiating with an important client. Still others are reluctant to initiate requests in general. This article discusses the personal characteristics and situational factors that influence an individual's likelihood of engaging another party in a negotiation, making a request, and optimizing that request. Herein, specific suggestions are offered for managing this critical phase of the negotiation process via three steps: mental preparation prior to the engagement; positioning prior to, and at the point of, the engagement; and verbal craftsmanship during the delivery of one's request.  相似文献

We analyse the interaction between the dividend policy and the decision on investment in a growth opportunity of a liquidity constrained firm. This leads us to study a mixed singular control/optimal stopping problem for a diffusion that we solve quasi-explicitly by establishing a connection with an optimal stopping problem. We characterize situations where it is optimal to postpone the distribution of dividends in order to invest at a subsequent date in the growth opportunity. We show that uncertainty and liquidity shocks have an ambiguous effect on the investment decision.   相似文献

Using the ‘societal-effect’ approach, a variant of the institutional theory developed and tested in Europe, this study investigates the impact of societal institutions on human resource management (HRM) practices of European multinational subsidiaries in Bangladesh, which is now on the list of the Next-11 economies of the world. In-depth case studies of four European multinational subsidiaries revealed the presence of different degrees of influence – partly attributable to societal effect – on the human resource practices of these subsidiaries. Our study added a new dimension to the interface between the strong and weak institutions and how such interfacing accords both legitimacy and reverse legitimacy to MNC subsidiaries and their societal institutions respectively. Another interesting finding of the study is the emergence of political system as a societal institution and, hence, a determinant of HRM practices in these subsidiaries. The study's implications are given.  相似文献
