Bubbles for Fama

We evaluate Eugene F. Fama's claim that stock prices do not exhibit price bubbles. Based on US industry returns (1926?2014) and international sector returns (1985?2014), we present four findings (1) Fama is correct in that a sharp price increase of an industry portfolio does not, on average, predict unusually low returns going forward; (2) such sharp price increases predict a substantially heightened probability of a crash but not of a further price boom; (3) attributes of the price run-up, including volatility, turnover, issuance, and the price path of the run-up, help forecast an eventual crash; and (4) these attributes also help forecast future returns. Results hold similarly in US and international samples.     

Business portfolio restructuring,prior diversification posture and investor reactions

This study examined firm performance in market reaction to two types of business portfolio restructuring announcements: refocusing and repositioning. We predicted that market performance effects for these two types of strategic restructurers would be moderated by prior diversification posture. The theory behind these expectations was built on a general premise that restructuring strategy would be more favorably viewed by the market as performance enhancing when it offered greater potential for organizational transformation. Results showed strong support for our conclusion that prior diversification posture poses a significant contingency factor in restructuring firms' strategic choices. Further, the market tended to respond more favorably with this sample to repositioning restructuring choices. Copyright © 2003 John Wiley & Sons, Ltd.     

A tale of three cities: Large,medium, and small consumer markets compared

In what size consumer markets does the consumer fare best — those of large, medium-sized, or small cities/towns? This is the general question that this article seeks to answer through analysis of price-quality data pertaining to Minneapolis (a large city), Ann Arbor, MI, and Ithaca, NY (a small town). While differences were smaller than expected, limited evidence from this pilot study support the notion that small markets are most efficient. At the same time the analysis confirms others' findings that most consumer markets are chaotic.     

THE ARBITRAGE PRICING THEORY AND COST-OF-CAPITAL ESTIMATION: THE CASE OF ELECTRIC UTILITIES

Capital asset pricing model (CAPM) and alternative arbitrage pricing theory (APT) methodologies are used to estimate the cost of capital for a sample of electric utilities. The statistical factors APT method is found to produce significantly different estimates depending on the number of factors specified and the set of firms factor analyzed. The use of macroeconomic factors is explored, and it is shown that this methodology has advantages over the statistical factors APT and the market model.     

Career Analysis: the Missing Link In Managerial Assessment and Development

Robin Jacobs and Robert Bolton argue that, although competency-based assessment methods have improved the haphazard management development practices of the past, they nonetheless provide an incomplete picture for improving performance and developing potential. They suggest that self-development through a career planning framework might provide the missing link and present a case study in this area based on their work in the Nationwide Building Society. Robin Jacobs is a Lecturer in Management at the Open University Business School as well as one of the directors of Transitions Limited, and Robert Bolton is Human Resources Manager at the Nationwide Building Society.     

Computing occupations: organizational power, work transition and collective mobility

The computing occupations are in a state of transition between a technical service and something more central to organizational power and decision-making. This process has had complex implications for the nature of computing work and for careers. There is no certainty that embryonic changes will carry through. But neither should the chances of these occupations of mounting a 'collective mobility project' be written off early.     

ON MANAGING HYBRIDS: SOME DILEMMAS IN HIGHER EDUCATION MANAGEMENT

This is an exploratory and conceptual paper. It argues that the concept of a hybrid organisation offers a useful way of conceptualising some dilemmas of current higher education management. The process of hybridisation captures some of the internal stresses and management problems facing higher education institutions caught between quasi-market and commercial market pressures. The increasingly widespread contractual management style may offer an inappropriate coping structure for some of these dilemmas. An open, negotiating management style, making explicit the problems of accountability and legitimacy generated by hybridisation, may be the only way to maintain staff commitment, but is very hard to achieve in the current context.
