Determinants of retail profit performance: A consideration of retail marketing strategies

The influence of retail marketing strategies on profit performance was investigated for a sample of thirty-five retail firms for the nine year period from 1970–1978 (n=315). Sales growth, market share, the capital-to-labor-ratio, and average inventory were found to be significantly associated with profit performance as hypothesized. Findings suggest that the keys to evaluating and selecting retail marketing strategies are: the impact on sales growth, market share, capital-to-labor ratios, and the average inventory level. Managerial implications are presented.     

THE ENTREPRENEURIAL EMPLOYEE

The business world goes around not just because of entrepreneurs, small and large, but because of entrepreneurial employees, as well. We discuss this insight and provide some illustrations.     

An investigation of long memory in various measures of stock market volatility, using wavelets and aggregate series

Using methods based on wavelets and aggregate series, long memory in the absolute daily returns, squared daily returns, and log squared daily returns of the S&P 500 Index are investigated. First, we estimate the long memory parameter in each series using a method based on the discrete wavelet transform. For each series, the variance method and the absolute value method based on aggregate series are then employed to investigate long memory. Our findings suggest that these methods provide evidence of long memory in the volatility of the S&P 500 Index. Our esteemed colleague, Robert DiSario, passed away on December 31, 2005.     

Job Satisfaction as a Function of Top Management Support for Ethical Behavior: A Study of Indian Managers

Based on organizational justice theories and cognitive dissonance theories, the authors hypothesized that: (a) perceived top management support for ethical behaviors will be positively correlated with all facets of job satisfaction (supervision, pay, promotion, work, co-workers, and overall); and (b) the correlation will be highest with the facet of supervision. Empirical results (n = 77 middle level managers from two organizations in South India) supported only the second hypothesis. Implications for managing a global workforce are discussed.     

An Adversarial Ethic for Business: or When Sun-Tzu Met the Stakeholder

In the economic literature on the firm, especially in the transaction–cost tradition, a sharp distinction is drawn between so-called “market transactions” and “administered transactions.” This distinction is of enormous importance for business ethics, since market transactions are governed by the competitive logic of the market, whereas administered transactions are subject to the cooperative norms that govern collective action in a bureaucracy. The widespread failure to distinguish between these two types of transactions, and thus to distinguish between adversarial and non-adversarial relations, has led many business ethicists to develop a “uniform” moral code. Yet in market transactions, the checks and balances built into the system of commercial exchange are such as to permit more instrumental forms of behavior. In administered transactions, by contrast, these checks and balances are absent, and thus the institutional context calls for much greater exercise of moral restraint. In this paper, I begin the task of developing an adversarial ethic for business. According to this view, the competitive environment licenses a greater range of “self-interested” behavior, but also imposes its own constraints on the strategies that firms may adopt in the pursuit of their interests.

He is the author of three books: Communicative Action and Rational Choice (MIT Press, 2001), The Efficient Society (Penguin, 2001), and with Andrew Potter. The Rebel Sell (HarperCollins, 2004). His research focuses on practical rationality, normative economics, and critical theory.     

The information content of option implied volatility surrounding the 1997 Hong Kong stock market crash

This study examines the information conveyed by options and examines their implied volatility at the time of the 1997 Hong Kong stock market crash. The author determines the efficiency of implied volatility as a predictor of future volatility by comparing it to other leading indicator candidates. These include volume and open interest of index options and futures, as well as the arbitrage basis of index futures. Using monthly, nonoverlapping data, the study reveals that implied volatility is superior to those variables in forecasting future realized volatility. The study also demonstrates that a simple signal extraction model could have produced useful warning signals prior to periods of extreme volatility. These results indicate that the options market is highly efficient informationally. © 2007 Wiley Periodicals, Inc. Jrl Fut Mark 27:555–574, 2007
