RISK, SEASONALITY AND THE ASYMMETRIC BEHAVIOUR OF STOCK RETURNS

For some time there has been a puzzle surrounding the seasonal behaviour of stock returns. This paper demonstrates that there is an asymmetric relationship between systematic risk and return across the different months of the year for both large and small firms. In the case of both large and small firms systematic risk appears to be priced in only two months of the year, January and April. During the other months no persistent relationship between systematic risk and return appears to exist. The paper also shows that when systematic risk is priced, the size of the systematic risk premium is higher for large firms than for small firms and varies significantly across the months of the year.     

Clusters,knowledge spillovers and new venture performance: An empirical examination

Firms in geographic regions with industry clustering have been hypothesized to possess performance advantages due to superior access to knowledge spillovers. Yet, no prior studies have directly examined the relationship between a firm's location within a cluster, knowledge spillovers and firm performance. In this study, we examine whether technological spillovers explain the performance of new ventures in cluster regions. We find that ventures located within geographic clusters absorb more knowledge from the local environment and have higher growth and innovation performance, but contrary to conventional wisdom, technological spillovers are not the contributing cause of higher performance observed for these firms.     

THE DISTRIBUTION OF PUBLIC EXPENDITURE AMONG HOUSEHOLDS IN THE UNITED STATES*

This paper presents an analysis of the distributive impact of government expenditures in the United States. The analysis uses a household-level microdata file drawn from the 1970 U.S. Census of Population, with additional income and tax variables drawn from the Internal Revenue Service 1969—70 Tax File. The results are presented at both federal and local levels and include analyses of the distribution of individual benefits, as well as of overall taxes and net benefits. Since a microdata file was used, distributional effects are examined with respect not only to the “traditional” variables of income class and household size, but also with regard to the number of earners in the household and the sex and race of the household head. In a further paper in a subsequent issue of this review we will present the results of a similar analysis for the United Kingdom, and compare the results for the two countries.     

An Exploration of the Conditional Timing Performance of UK Unit Trusts

Abstract:  We examine the conditional market timing performance of UK unit trusts between January 1988 and December 2002. We find no evidence of superior conditional market timing performance by UK unit trusts either across different portfolios of trusts or by individual trusts. We also find that benchmark investing is significant for UK unit trusts and trusts have high numerical risk aversion to deviations from the benchmark. Our findings suggest that UK trusts act like benchmark investors.     

Local measured telephone service in the USA: A quantitative analysis

The USA has steadfastly held to a flat rate for local telephone service, whereas most other countries are characterized by a user-sensitive (measured service) system of pricing. Economic theory suggests some method of measured service pricing more accurately reflects the true costs of local service. This article seeks to determine how many US consumers could be induced to switch to measured service pricing, and using ordinary least squares, derives a model of the demand for measured service. The factors are identified that will induce the US population to move towards a measured service rate structure. The findings indicate that consumers are quite responsive to both relative price (between a local flat rate and a measured service rate) and advertising.     

Accountability and responsibility in research

Fraud and misconduct in scientific research appears to be increasing since 1980 when several cases were disclosed. Earlier instances were handled awkwardly, but the scientific community has since mobilized and issued guidelines about responding to allegations of misconduct and about the responsible conduct of research. Scientists, editors and the institutions of science are slowly learning how to cope with this problem.Patricia Woolf studies communication among scientists and has taught sociology of science. Her recent work has focused on research on misconduct, conflict of interest and the professionalization of medical editing.     

Engineers and management: The challenge of the challenger incident

The Challenger incident was a result of at least four kinds of difficulties: differing perceptions and priorities of the engineers and management at Thiokol and at NASA, a preoccupation with roles and role responsibilities on the part of engineers and managers, contrasting corporate cultures at Thiokol and its parent, Morton, and a failure both by engineers and by managers to exercise individual moral responsibility. I shall argue that in the Challenger case organizational structure, corporate culture, engineering and managerial habits, and role responsibilites precipitated events contributing to the Challenger disaster. At the same time, a number of individuals at Morton Thiokol and NASA were responsible for the launch failure. Differing world views, conflicting priorities of the engineers and managers on this project, and the failure of either engineers or management to take personal moral responsibility for decision-making contributed significantly to the event.
