Structure and understanding: Some observations on current activities in the field of structural modeling

Structural modeling has been under study in recent years as a method for dealing with complex societal problems, and is growing in acceptance as a tool for understanding complex social phenomena. Structural models demonstrate the interactions of the separate elements of a system and their combined overall effect. Thus, the nature of the problem for which this method of analysis is appropriate is different from complex problems of the traditional disciplines which lend themselves to reductionist approaches. This is because complex policy problems of society cannot be “solved” with precise analysis. Kenneth Boulding suggests that there are two ways to cope with a complex policy problem, either to “slice” the problem into partial equilibrium sections or “squeeze” it by aggregating numerous variables into a single index or macho variable. Structural modeling is an approach which comes under the general strategy of squeezing the problem and is promising because of the ability to include a range of macro variables which provide insights about social change. The articles in this issue treat several interesting aspects of this approach. In this article we wish to recall for consideration a central purpose for developing such methods. We have taken a historical approach to indicate some of the roots of the concern for the effect of technological process on social change. Within this context, we discuss the nature of the contributions made by the articles in this issue and what promise the methods offer to addressing the historical concern.     

Collaboration, peer review and open source software

Open source software development may be superior to proprietary development because the open source organizational form naturally minimizes transactions costs associated with privately distributed information. This manifests itself in the ability of open source communities to encourage critical peer review and the sharing of ideas. When these activities are important, the open source organizational form may do better than a proprietary organizational form. My results suggest why open source is particularly powerful when maintainability of software is critical, and also suggest that the founder of a software project may be more likely to choose open source if there is an existing dominant proprietary software project.     

The Influence of Environmental Pressures, Diversification Strategy, and Union/Nonunion Setting on Employee Participation

This study tests the hypotheses that environment, diversification strategy, and union/nonunion setting affect the number and variety of employee participation programs. A survey of large U.S. manufacturing firms measured the implementation of employee participation programs. Regression results suggest that environmental pressures exert a direct effect on participation in union settings. However, in nonunion settings, environment and diversification strategy both correlated directly with participation. These results suggest that unions could potentially affect participation program implementation.     

中国农村社区公共物品投资的决定因素分析

本文使用具有全国代表性的抽样调查数据,对农村社区公共物品投资的决定因素进行了初步的分析。本文通过理论分析提出了两个理论假说,进而提出在我国公共投资中要注意的问题:既要考虑各地对公共投资有不同的需求,还要考虑区域协调发展。研究结果表明,除了一些政策因素以外,当地经济发展水平是影响农村公共投资的重要因素,一般来说,在工商业较发达的村公共投资活动也相对较多。对于外出务工人员较多的村,由于本地公共投资对外出务工人员的收入等作用较小,因此这部分村民就不那么愿意对村里进行公共投资。从政策实施角度看,本研究发现,上级政府的公共投资更多地投向贫困地区、偏远山区、农业生产条件差的地区或少数民族地区。这种投资战略有助于统筹区域发展,降低区域差异。     

Consumer ethics: The possible effects of terrorism and civil unrest on the ethical values of consumers

Research investigating the consumer's ethical beliefs, ideologies and orientation has been limited. Additionally, despite the repeated call in the literature for cross cultural research, virtually no studies have examined the ethical beliefs and ideologies of consumers from cultures other than those in North America. This study partially fills this gap in the literature by investigating the ethical beliefs, preferred ethical ideology, and degree of Machiavellianism of consumers from Egypt and Lebanon. The results indicate that consumers in Lebanon, which has been torn by civil unrest and terrorism, tend to be more Machiavellian, less idealistic, and more relativistic than their Egyptian counterparts. Additionally, the Lebanese consumers tend to be more accepting of questionable consumer practices.Mohammed Y. A. Rawwas is Assistant Professor of Marketing at the University of Northern Iowa.

Capital, corporate income taxes, and catastrophe insurance

We provide estimates of the equity capital needed and the resulting tax costs incurred when supplying catastrophe insurance/reinsurance using a partial equilibrium model that incorporates a specific loss distribution for US catastrophe losses. After consideration of insurer investment in tax-exempt securities, tax loss carry-back/forward provisions, and personal taxes, our results imply that the tax costs of equity finance alone have a substantial effect on the cost of supplying catastrophe reinsurance. These results help explain a variety of industry developments that reduce tax costs. Also, when coupled with non-tax costs of capital, these results help explain the limited scope of catastrophe insurance/reinsurance.     

Binomial Option Pricing with Skewed Asset Returns

This research presents a method for estimating the parameters of the binomial option pricing model necessary to appropriately price calls on assets with asymmetric end-of-period return distributions. Parameters of the binomial model are shown to be a function of the mean, variance, and skewness of the underlying return distribution. It is also shown that failure to incorporate skewness results in the mispricing of the call.     

The Relationship Between Market Efficiency and Insider Ownership in Large and Small Firms

The study examines insider ownership in large and small firms in relation to market efficiency. Recent studies have found a positive and significant relation between inside ownership and stock market performance. Such a finding is predicated upon the idea that inside ownership minimizes agency costs caused by the conflict between hired managers and shareholders. It is argued here that semi-strong form market efficiency requires that all public information, including insider ownership, be quickly impounded into the price of a stock. If that is the case, the expected present value of a change in agency cost should be incorporated into the stock price shortly after any significant change in ownership. Hence, if the estimate is unbiased, the longer-term performance of firms should not be effected by such changes. The issue is examined for both large, well-known firms and for smaller, less-known firms. The hypothesis that markets are generally efficient with respect to insider ownership information is rejected.
