An Analysis of the Distribution of Extreme Share Returns in the UK from 1975 to 2000

This paper seeks to characterise the distribution of extreme returns for a UK share index over the years 1975 to 2000. In particular, the suitability of the following distributions is investigated: Gumbel, Frechet, Weibull, Generalised Extreme Value, Generalised Pareto, Log‐Normal and Generalised Logistic. Daily returns for the FT All Share index were obtained from Datastream, and the maxima and minima of these daily returns over a variety of selection intervals were calculated. Plots of summary statistics for the weekly maxima and minima on statistical distribution maps suggested that the best fitting distribution would be either the Generalised Extreme Value or the Generalised Logistic. The results from fitting each of these two distributions to extremes of a series of UK share returns support the conclusion that the Generalised Logistic distribution best fits the UK data for extremes over the period of the study. The Generalised Logistic distribution has fatter tails than either the log‐normal or the Generalised Extreme Value distribution, hence this finding is of importance to investors who are concerned with assessing the risk of a portfolio.     

The Views of ‘Knowledge Gatekeepers’ About the Use and Content of Accounting Textbooks

This study examines financial accounting educators' views about, and use of, recommended course textbooks in the UK. In particular, this research explores the factors that influence the selection of a recommended text, the role it plays on the course, and educators' perceptions of the worldview that underpins their chosen text. Drawing on the results of a questionnaire survey and semi-structured interviews with introductory financial accounting educators, this study draws attention to ideological issues concerning accounting textbooks. In particular, findings from this research suggest that a number of educators feel that their recommended textbooks should discuss the information needs of a broad range of stakeholders and supplement their text with materials that provide alternative perspectives or which draw attention to current issues in accounting. Moreover, a number of the participants indicated that their textbook had ideological characteristics in so far as they had an overly technical focus which ‘obscured’ the values that underpinned them.     

An investigation of the stability of returns in Western European equity markets

This paper investigates the temporal stability of various dimensions of the returns of 16 European stock markets that are relevant to an analysis of international portfolio diversification. The basic data consist of daily stock market price indices for these markets. This group of indices comprehends a wide range of stock markets differentiated by size, age and technological sophistication, but in each case located in Western Europe. Two main tests were conducted: (a) ANOVA to identify inter-temporal variability and inter-market variability over 24 three-month sub-periods from January 1989 to December 1994, and (b) cluster analysis to identify groups of markets that exhibit similar behaviour patterns. The findings suggest that, while the potential gains from an internationally diversified portfolio restricted to the equities of Western European markets appear to be substantial, the lack of inter-temporal stability in the composition of the optimal portfolio from one period to another makes these gains difficult to achieve in practice.

A NEW APPROXIMATE GLS ESTIMATOR FOR THE REGRESSION MODEL WITH MA(1) DISTURBANCES

This paper introduces a new approximate GLS estimator for the regression model with MA(1) disturbances, which outperforms both the Balestra (1980) and the Park and Heikes (1983) approximations and which is almost as efficient as the exact GLS estimator.     

Flexibility,Firm-Specific Turbulence and the Performance of the Long-lived Small Firm

The hypothesis that flexibility enhances the long run prospects of the small firm is explored by examining precipitating causes of organizational change within it, and consequential adjustments. The study is fieldwork based and uses evidence gathered directly from entrepreneurs. New measures of flexibility and firm-specific turbulence are used to explain long-run performance, measured over 28 distinct attributes. Econometric estimates (using GLS and Heckman selectivity correction) are reported, on the relationship between flexibility, firm-specific turbulence and performance. Firm-specific turbulence is shown to have a negative effect on performance, but the latter is enhanced by increasing the flexibility of the small firm.JEL classification: C42, D21, G33, L2, M13, M21.     

Introduction: Organizations, Risk and Regulation

abstract    Risk, regulation and practices of organizing are interrelated in a myriad of ways. Natural disasters, technical failures, and also processes of organizing are sources of risk to which organizations must respond and for which new managerial and regulatory practices are demanded. In this introduction we highlight three salient features of risk management: the (un)intended production of risk by organizations; the complex interrelationship between risk management and regulation; and the evolving and often contested nature of risk management knowledge. Each of these three themes is evident in the different contributions to this themed section.
