Solutions to the Asset Allocation Problem by Informed Respondents: The Significance of the Size-of-Bet and the 1/N Heuristic

Asset allocation is a classic topic in the theory of finance and a crucial issue for investment policy. Noted for its significance in driving pension fund performance, it is also an issue that individual investors consider when designing their investment portfolios. In theory, Markowitz and those following in his wake have an optimal solution. In practice, however, we show that when asked to allocate their own money to a set of asset classes (from relatively low risk to high risk) in an experimental situation, most of our informed respondents would vary their investment strategies according to the size-of-bet (the money value of assets to be invested). We also show that most participants in the study adopted one of three solutions to the posed problem only one of which could be thought consistent with Benartzi and Thaler's 1/ n  heuristic. Since respondent solutions do not seem to be explained by formal education, professional qualifications, or training, it is suggested that solutions to the asset allocation problem are a product of strategies that mix intuitive responses to the initial tranche of money with theoretical cum practical shared conventions. Solutions to the asset allocation puzzle suggest that the size-of-bet could be a significant consideration for many informed investors. In conclusion, suggestions are made about taking forward closer scrutiny of these experimental results.     

Student Ethical Perceptions and Ethical Action Propensities: An Analysis of Situation Familiarity

Recently McCuddy and Peery (1996) have suggested that business students may not respond the same way to unfamiliar business ethical dilemmas as they would to more familiar academic ethical dilemmas. The purpose of this study was to present the same students with both unfamiliar business dilemmas as well as possibly more familiar academic dilemmas in order to examine this issue.Findings of the study revealed that students did not exhibit different perceptions of the unethical actions performed in the academic and accounting/business ethical vignettes. However, the students indicated that both they and their peers would be more likely to act unethically to resolve the dilemmas in the accounting/business cases than in the academic cases. This finding is troubling in that it suggests that students either feel less compelled to act ethically in business, or that they perceive that ethical standards in the business world are generally low when compared to their current educational environment. In addition, the students in the study maintained the same halo effect (i.e., the difference between an individual's perception of their likelihood of performing an unethical action compared to their perception of their peers' likelihood to perform the same unethical action) across the two types of ethical dilemma.     

What states are doing to control health insurance costs

Like other employers, state governments are struggling with continued health care cost increases. A 50-state survey reveals that these large public employers are actively attempting to control the cost of their plans while ensuring quality and a commitment to their employees' overall good health.     

Age of rental housing units and vacancy characteristics A filtering explanation

Aggregate data on rental units indicate that older units have lower vacancy frequencies and higher vacancy durations than newer units. A formulation consistent with the filtering hypothesis of the housing literature is presented that explains the above empirical regularity.     

Bidder collusion

We analyze bidder collusion at first-price and second-price auctions. Our focus is on less than all-inclusive cartels and collusive mechanisms that do not rely on auction outcomes. We show that cartels that cannot control the bids of their members can eliminate all ring competition at second-price auctions, but not at first-price auctions. At first-price auctions, when the cartel cannot control members’ bids, cartel behavior involves multiple cartel bids. Cartels that can control bids of their members can suppress all ring competition at both second-price and first-price auctions; however, shill bidding reduces the profitability of collusion at first-price auctions.     

An empirical investigation of technology acceptance in a field sales force setting

Gaining technology acceptance by salespeople is critical in modern organizations. Sales technology is an integral tool for enhancing customer-related information management and knowledge development. Knowledgeable salespeople are able to use the information and knowledge to practice adaptive selling, improve performance, and enhance their firm's competitive advantage in the marketplace. This study proposes and tests a model linking technology acceptance to adaptive selling and job performance of field salespeople. The results provide evidence that behavioral intentions to use technology positively affect salesperson performance through enhanced propensity to practice adaptive selling. Implications of the study for managers and researchers are discussed.     

International Equity and Differentiation in Global Warming Policy

ne of the major obstacles to reaching a comprehensive agreement on global warming is the setting of greenhouse gas emission reduction targets for individual countries. Long-standing tensions between industrialized and developing countries have raised the issue of equity in burden-sharing. Moreover, individual industrialized nations have pleaded special circumstances and have sought differentiation in their obligations. This paper analyzes alternative rules for distributing tradable carbon dioxide emissions permits. A non-linear programming model, which distinguishes between allocation-based and outcome-based rules, is used to analyze the relative welfare outcomes. The model is applied to the world body of nations and yields several important policy implications.
