Modeling ethical attitudes and behaviors under conditions of environmental turbulence: The case of South Africa

This study explores the impact of environmental turbulence on relationships between personal and organizational characteristics, personal values, ethical perceptions, and behavioral intentions. A causal model is tested using data obtained from a national sample of marketing research professionals in South Africa. The findings suggest turbulent conditions lead professionals to report stronger values and ethical norms, but less ethical behavioral intentions. Implications are drawn for organizations confronting growing turbulence in their external environments. A number of suggestions are made for ongoing research. Michael H.

Asymptotic expansion of S-estimators of location and covariance

By means of a straightforward application of empirical process theory, we show that S-estimators of multivariate location and covariance are asymptotically equivalent to a sum of independent vector and matrix valued random elements respectively. This provides an alternative proof of asymptotic normality of S-estimators and clearly explains the limiting covariance structure. It also leads to a relatively simple proof of asymptotic normality of the length of the shortest α-fraction.     

State takeover legislation and share values: The wealth effects of Pennsylvania's Act 36

Proponents of state antitakeover legislation argue that previous empirical tests by financial economists of the wealth effects of Pennsylvania's 1990 antitakeover law are biased. We show that the proponents are correct. In particular, firm size, event-time clustering, and non-synchronous trading effects account for the wealth decreases reported in earlier studies. We also show, however, that both proponents and critics of the Pennsylvania legislation have ignored the earliest press release about it. The wealth effect associated with this announcement is negative, large, and statistically significant. These results therefore are consistent with the hypothesis that the Pennsylvania law decreased company values and with the hypothesis that the initial market reaction is an unbiased estimate of the law's effect on firm values.     

A de Finetti-Kolmogoroff-Nagumo type integral representation theorem for generalized means on masses

We point out that the Consistency, Continuity and Associativity properties of an extended realvalued functionalm on masses are the basic notions to get a de Finetti-Kolmogoroff-Nagumo type integral representation ofm.

Riassunto Come è noto il teorema di de Finetti-Kolmogoroff-Nagumo formisce una rappresentazione integrale di particolari funzionali reali, detti medie, definiti per funzioni di ripartizione che distribuiscono l'intera massa su un prefissato intervallo chiuso e limitato dell'asse reale.Nel lavoro [2] gli autori hanno esteso la nozionc di media, considerata ancora come funzionale reale, dalle funzioni di ripartizione alle masse (misure finitamente additive limitate e non negative). In questo modo, estendendo ad essa le usuali proprictà (internalità, associatività, etc.), sono riusciti a provare un teorema di rappresentazione integrale analogo a quello di de Finctti-Kolmogoroff-Nagumo per medie continue ed associative definite su opportuni insiemi di masse tight (cio prive di masse aderenti a – e+).In questo lavoro, naturale prosccuzione del preccedente, si prendono invecc in considerazione medic generalizzate (cioè medie che possono assumere valori reali oppure anche i valori – c+) e masse non neccssariamente tight. Si fa allora vedere che le nozioni di consistenza, continuità e associatività per un funzionale a valori nella retta compatta e definito sulle masse non nulle, sono condizioni caratteristiche per ottencre una sua rappresentazione integrale del tipo de Finctti-Kolmogoroff-Nagumo. Si prova inoltre che, a differenza della media ariumetica, le medic generalizzate continue ed associative possono assumere valori non reali solamente su opportune masse non tight.

In search of the meaning of entrepreneurship

This paper is an attempt to build a bridge between the popular and the academic usage of the terms entrepreneur and entrepreneurship, and to identify the raw materials needed to construct an interpretive framework capable of illuminating the nature of entrepreneurship and its role in economic theory. We review briefly the contributions made to this topic by Cantillon, Schumpeter, Schultz and Kirzner. We advance a synthetic definition of the entrepreneur as someone who specializes in taking responsibility for and making judgemental decisions that affect the location, the form, and the use of goods, resources, or institutions. We then conclude with some observations on the basic choice confronting economics regarding the place of entrepreneurship in economic analysis.     

Professionals and social responsibility: Some patterns

Modern professionals are engaged in making things better, but the specific advances on the micro-level are increasingly undercut by problems on the macro-level. The content of this better is typically guided by values such as efficiency, productivity or cost-effectiveness, which are essentially output over input ratios unable to account for how a specific improvement will fit into the broader human, social and ecological contexts. Hence, micro-level advances lead to fragmentation and a loss of harmony, compatibility and conviviality. The situation is further complicated by the fact that, culturally speaking, science and technology have become good in themselves, making reasonable discourse difficult. This paper concludes with an analogy from an earlier epoch suggesting how the situation may be resolved. After completing a doctorate in Mechanical Engineering, Willem Vanderburg continued his studies of technology via the social sciences and humanities. He is currently the Director of the Centre for Technology and Social Development in the Faculty of Applied Science and Engineering at the University of Toronto.

Corporate ethical consulting: Developing management strategies for corporate ethics

The increase of scandals in the business sector is forcing many companies to examine their corporate ethical behavior with a view toward rebuilding their corporate value system. This article describes how value-system reconstruction must proceed in a company and demonstrates that corporate ethics can only become plausible if based on a corporate ethical ethos. It outlines a five-step development plan of management strategies toward rebuilding a company's value system on this corporate ethos through: corporate policy and strategy reformulation; corporate ethical code promulgation and value-statement formulation; management ethical training and corporate ethical education; and corporate ethical performance evaluation. The role of the corporate ethical consultant is also outlined to illustrate how corporate ethical consulting can provide the specialized services designed to insure an enduring management ethical upgrading and to improve a company's corporate ethical performance record. The discussion indicates how corporate ethical consulting promotes good business through its capacity to deliver industry credibility and company security. Richard Guerrette is a Research Fellow at Yale University Divinity School, where he is conducting a research study in organization management process and corporate ethics. He is also a Lecturer in sociology at the University of Connecticut at Hartford and is an author of two books on ecumenical ministry and social movement organization in the church. He has published extensively in theological journals and has recently contributed an article on Environmental Integrity and Corporate Responsibility for the Journal of Business Ethics 5 (1986). He is the Director of Equipax, an organization/management consulting service in Farmington, Connecticut.     

A theoretical foundation for Constant Market Share analysis

Constant Market Share (CMS) analysis is a popular tool for analyzing changes in exports of a country. Nevertheless, its theoretical foundations (and policy relevance) have been questioned. In this paper, we provide such a foundation by relating CMS analysis to a two-stage homothetic demand model. An indication of the empirical relevance of this relationship is given by comparing the CMS analysis with a two-stage Constant Elasticity of Substitution demand model applied to 1972–1976 data of the Economic and Social Commission for Asia and the Pacific (ESCAP).Paper presented at the XX-th world conference of the Applied Econometric Association in Istanbul, December 1986.
