Game theory and open source contribution: Rationale behind corporate participation in open source software development

The rising participation of for-profit corporations in the development of open source software raises the question of why corporations are motivated toward this engagement. The increased participation is an observable phenomenon; many researchers and practitioners assume that the practice of community sharing does not improve the bottom line, but rather believe the practice is altruistic in nature. Our intuition is that participation offers tangible and intangible benefits to corporate participants. We show this by exploring a variety of models in game theory and use game theory as a methodological lens to explain the rationality of corporate participation in open source software development. Since game theory has evolved to include rational- and emotional-based reasons, we explore such lenses as cooperative games, metagames, coopetition, and Drama Theory. Our research question, “Why do for-profit corporations participate in the development of open source software?” was broad enough to adopt several useful perspectives to understand our data. One useful lens was game theory. In this article, we examine interview responses and field study data from corporate members of open source communities to determine how they justify devoting time and effort to community engagement. Our study makes a contribution to open source software literature by revealing that numerous rational and emotional reasons exist for corporate participation in open source software development.     

Asset preference,skewness, and the measurement of expected utility

This article shows that serious analytical errors may occur in expected utility theory when Taylor series approximation methods are used without careful attention to underlying mathematical assumptions. Recent studies have developed theory incorporating skewness of return into expected utility calculations based on a Taylor series approximation. It is apparent that this theory is invalid if assumptions for application of a Taylor series cannot be met. Errors may occur if returns fall outside the region of convergence of the utility function ot if the partial sums of the Taylor series provide poor approximations to the utility function. Stylized examples are presented to illustrate miscalculation of utility when the various assumptions are violated. These examples are motivated by the use of Taylor series approximations in current literature which deal with the new spectrum of financial securities.     

The Moral of the Story: Re-framing Ethical Codes of Conduct as Narrative Processes

This paper re-frames business ethical codes (BCEs) as narrative processes by reflecting critically on key ontological assumptions underpinning the existing research, and introducing new and relevant concepts based on alternative assumptions. The first section draws on recent decision-making research to develop a theoretical account of BCEs as complex, socially embedded sensemaking processes. The second section addresses the content of codes, and differentiates between narrative and logico-scientific modes of reasoning. The third section focuses on the quality of code communication and identifies several distinct types of narrative process. We provide research directions for how this new understanding of BCEs may be further developed, as well as implications for practitioners. In response to the call for new conceptual models (O’Fallon and Butterfield, in J Bus Ethics 59:375–413, 2005), the paper provides organizational researchers with a more nuanced understanding of how BCEs enable or constrain ethical behavior in organizations.     

The impact of CAP reform on farmers’ plans for the future: Some evidence from South West England

This paper considers farmer intentions following the implementation of the 2003 CAP reforms, identifies the extent to which these plans have been influenced by the introduction of the Single Payment Scheme (SPS) in 2005 and considers the implications in terms of likely structural change (i.e. changes in the deployment of land, labour and capital). The analysis uses data from a large sample survey of farmers in South West England and the results indicate that CAP reform is not stimulating rapid agricultural restructuring, rather it appears to be reinforcing many existing trends towards diversification and an increasing polarisation between the largest and smallest farms. CAP reform is impacting unevenly on the farm community and different farming situations are associated with different types of reaction. Market signals may become a more powerful driver of farmer behaviour, in which case the 2003 reforms will have proved successful in providing farmers the freedom to farm without coupled subsidies. On the basis of the results presented in this paper though, only a minority of farmers seem both well placed and well disposed to exploit such opportunities.     

Tacit Collusion in Price‐Setting Oligopoly: A Puzzle Redux

We study tacit collusion in price‐setting duopoly games with strategic complements and substitutes. While this problem has been considered by several studies, this article sheds new light on the comparison by focusing on the relationship between dynamic stability of equilibrium and tacit collusion. We find when controlling for the absolute slope of the reaction functions, there are no robust differences in either the convergence properties or tacit collusion between complements and substitutes treatments.

Emerging perspectives on the demonstration as a signature pedagogy in design and technology education

This paper analyses the beliefs of teachers regarding the demonstration as a signature pedagogy in design and technology, where there is a limited body of literature outlining the theory and practice. The demonstration is multifaceted, and effective teachers adopt and adapt a range of skills and values to scaffold learning, including teacher modelling and explaining. The study explores the subjective beliefs of seven practicing teachers through Q Methodology; comparing and analysing the responses of the participants’ subjective beliefs and values, using 62 statements relating to teacher modelling and explaining, developed and refined with teacher educators, and representing the concourse of opinions and perspectives. The sample is purposive, comprised of practicing teachers who are engaged with mentoring trainees in Initial Teacher Education. The findings will represent a snapshot of subjective values of practicing teachers, as part of a discourse on signature pedagogies in design and technology education.     

Competition to Save Lives: Political competition and health outcomes in India

Governance indicators have come under fire in recent years, especially the World Governance Indicators. Critics present these indicators as atheoretical and biased. Critics of the critics counter that no better alternatives exist. The authors suggest otherwise, arguing that more appropriate “governance” indicators will: have theoretical grounding; focus on specific fields of engagement; emphasize outcomes; and control for key contextual differences in comparing countries. Such constructs can help indicate where countries seem to have governance problems, allowing second-stage analyses of where and what these problems are; they do not directly point to the presence or nature of problems or provide a measure of the governance concept. Under-5 mortality rates adjusted for country income groups are shown as an example of such a measure, and data presented for contextually compared outcomes in this specific field to show where governance seems better and worse. The USA is shown up as relatively weak, whereas a country such as Pakistan seems to have better governance in this sector than other low-income countries. The indicator has its weaknesses and is partly presented as an illustrative example of a new approach, but also allows questions about why governance of this sector might be problematic in certain contexts and easier in others.
