The Role of Media Coverage in Explaining Stock Market Fluctuations: Insights for Strategic Financial Communication

This study investigates the reciprocal relationships between the fluctuation of the closing prices of three companies listed on the Amsterdam exchange index, namely ING, Philips and Shell and online media coverage related to these firms for a period of two years (2014–2015). Automated content analysis methods were employed to analyze sentiment and emotionality and to identify corporate topics related to the companies. A positive relation of the amount of coverage and emotionality with the fluctuation of stock prices was detected for Shell and Philips. In addition, corporate topics were found to positively Granger cause stock price fluctuation, particularly for Philips. The study advances past research in showing that the prediction of stock price fluctuation based on media coverage can be improved by including sentiment, emotionality, and corporate topics. The findings inform strategic communication, and particularly investor relations, in suggesting that media attention, sentiment, and certain corporate topics are crucial when managing media relations and with regard to securing a fair evaluation of listed companies. Furthermore, the innovative research methods are useful for researchers and practitioners alike in showcasing how media coverage related to firms and their stock fluctuations can be identified and analyzed in a reproducible, hands-on and efficient manner.     

The evolution of morality and the end of economic man

1871 saw the publication of two major treatises in economics, with self-seeking economic man at their center. In the same year Darwin published The Descent of Man, which emphasized sympathy and cooperation as well as self-interest, and contained a powerful argument that morality has evolved in humans by natural selection. Essentially this stance is supported by modern research. This paper considers the nature of morality and how it has evolved. It reconciles Darwin’s notion that a developed morality requires language and deliberation (and is thus unique to humans), with his other view that moral feelings have a long-evolved and biologically-inherited basis. The social role of morality and its difference with altruism is illustrated by an agent-based simulation. The fact that humans combine both moral and selfish dispositions has major implications for the social sciences and obliges us to abandon the pre-eminent notion of selfish economic man. Economic policy must take account of our moral nature.     

Can the Beast be Tamed?: Reflections on John McMurtry's Unequal Freedoms: The Global Market as an Ethical System

My paper responds to certain themes of Professor John McMurtry's recent book, Unequal Freedoms: The Global Market as an Ethical System. Although I am in general sympathy with McMurtry's penetrating critique of conventional market theory and practice, I find Unequal Freedoms ambivalent on the critical question of whether endorsing and enacting the life-value code McMurtry proposes would require only a mitigation of the principles and definitive activities of the competitive market system or whether significant reforms within the system would have to be deep structural ones. It is argued that the second alternative is inescapable. I defend my perspective from the point of view of a philosophical analysis of orthodox or neo-classical theory-construction about the competitive market order. In particular, I examine three fundamental principles of such modelling: the maximization of the satisfaction of self-interest, the unboundedness of consumer desire for material goods, and the distribution of monetized wealth. In order for McMurtry's "civil commons" to survive, the practice of each of these principles would need to be radically modified. However, in doing so, competitive capitalism would lose its essential identity as a socio-economic order.     

Measuring the Value of Product Characteristics in the Presence of Price Dispersion

Modeling the price of multi‐attribute products generally requires an assessment of each attributes' market value. In the presence of price dispersion, when similar products are sold at different prices, hedonic pricing models provide users with biased estimates of attribute value. This paper develops the hedonic pricing literature by proposing data envelopment analysis as a prior means of identifying a sub‐sample of products which, after adjusting for attribute provision, display no price dispersion. These products then display a homogenous link between attributes and price, which can be modeled using hedonic pricing. This paper implements and evaluates this two‐stage approach using 1000 observations from the UK mortgage market. Copyright © 2014 John Wiley & Sons, Ltd.     

Evolutionary game theory and evolutionary economics: are they different species?

Evolutionary game theory and evolutionary economics seem to inhabit different academic spheres and have little collaboration with one another. Neither side cites much research by the other. Does this de facto academic separation impede fruitful possibilities for mutual inspiration and joint development? This paper addresses this question by considering (1) the different origins and research orientations of the two genres, (2) to what extent evolutionary economists could make use of evolutionary game theory, and (3) what evolutionary game theorists might learn from other, less formal, modes of theorising. The paper concludes that while significant possibilities for collaboration exist, the foremost test is whether they can help enhance our understanding of structures and causal processes in the real world.     

The problem with pay flexibility: changing pay practices in the UK health sector

This paper critically assesses models and policies of pay flexibility as applied to the public sector. Examination of the arguments for greater pay flexibility across three dimensions - external labour market flexibility, organizational flexibility, and macroeconomic flexibility - reveals a number of weaknesses, rooted in a failure to problematize the conflicting motives for greater pay flexibility in the context of pressures internal and external to the organization. An alternative 'model' of changing pay systems is developed and applied to the case of the UK health sector where there have been attempts to introduce various forms of flexible local pay arrangements. Drawing on interviews conducted during the mid-1990s with personnel and HRM managers at fifteen NHS Trusts, a number of issues are examined, such as: the impact of differential external labour market conditions of workers on the development of strategies designed to tie local pay to improved performance; the introduction of performance-related pay as a means to institutionalize wider earnings differentials within the organization; and the potential conflict between pressures to link local pay structures with local labour market conditions, on the one hand, and customary employee-held norms that link pay to occupational skills and professional status, on the other.     

Accounting Window Dressing and Template Regulation: A Case Study of the Australian Credit Union Industry

This article documents the response of cooperative institutions that were required to adhere to new capital adequacy regulations traditionally geared for profit-maximising organisations. Using data from the Australian credit union industry, we demonstrate that the cooperative philosophy and internal corporate governance structure of cooperatives will lead management to increase capital adequacy ratios through the application of accounting window dressing techniques. This is opposite to the intended purpose of template regulation aimed at efficiently increasing operating margins and lowering risk. Our results raise several debatable issues regarding the ethics of accounting management and the imposition of one-shoe-fits-all external regulation.
