Spatial patterns of biodiversity conservation in a multiregional general equilibrium model

Migration dynamics and local biodiversity are interrelated in a way that is likely to affect patterns of regional specialisation. We assess this relationship with a New Economic Geography model that has been extended with biodiversity. Biodiversity is heterogeneous, and responds to habitat availability. The results indicate that a symmetric pattern of regional specialisation is more likely, and that additional equilibria may emerge as the marginal utility of biodiversity increases. In the policy analysis we focus on the case where the overall social optimum is symmetric and show that it can be supported as a non-cooperative Nash equilibrium. However, multiple Nash equilibria may exist.     

The critical discount factor as a measure for cartel stability?

This paper considers the stability of tacit collusion in price setting duopolies with repeated interaction. The minimum discount factor above which tacit collusion can be sustained in a subgame perfect equilibrium is called the critical discount factor δ*. In addition, δ* is often used as an intuitive measure for the stability of a tacit cartel, assuming that a collusive equilibrium is more difficult to sustain when δ* increases. However, according to standard theory the distance δ − δ* between the actual and the critical discount factor does not matter for stability as long as δ > δ*. This paper contributes experimental evidence that supports the intuitive idea that a larger critical discount factor makes collusion a less likely outcome.      

How Corporate Diversity and Size Influence Spinoffs and Other Breakups

In recent months, the list of large diversified companies that have decided they would be worth more as several smaller, focused companies has grown sharply. In many of these cases, it has been outside pressure from activist investors that has motivated these actions by management—and with some pretty favorable results. But what is driving these strategic actions and what is most important in determining whether breakups create value? To answer this fundamental questions, it is critical to decide whether large, diversified companies have a value recognition problem or a value creation problem. In this article, the authors present and try to integrate the findings of two separate but related research studies on business diversity and size with the aim of identifying their implications for corporate strategy and helping company executives create more value for their investors. The specific reasons for underperformance by large diverse companies vary greatly, but there are a number of potential problems discussed in this article, including organizational “distance,” capital allocation, human capital allocation, cross subsidies, and ineffective governance. Instead of waiting for activist investors to demand a breakup, executives of large diverse companies should be proactive in addressing the potential weaknesses of their organizations. Private equity firms understand how to make diversification work and many of today's executives could learn some valuable lessons from these firms. Large diverse businesses should embrace “Internal Capitalism,” a corporate culture and set of practices that emphasizes the importance of strategic decision‐making that is linked through continuous performance assessment to the corporate goals of boosting efficiency and sustainable growth.     

Knowing one’s place: The distribution of new accounting academics into a segmented labor market

New academic accountants tend to believe that there is a singular academic labor market that will receive them as they approach the completion of their doctoral programs. In such a world, the caliber of their ideas would be judged according to their ability to make a contribution to the knowledge of discipline. However, past research suggests that a prestige structure exists for doctoral programs such that a candidate’s ability to be placed at a school is a function of his/her doctoral programs position in that hierarchy. In this world, limits exist upon possible placement for most candidates such that the caliber of their work will not be a determinative factor in their placement. Various divisions of the doctoral schools in accounting show that movement to higher groups is difficult for all groups. The higher-tier schools are more able to place their graduates in the same tier. Falls to lower tiers are especially likely for the graduates of the lower prestige groups of doctoral schools. This paper seeks to help participants in the labor market, doctoral candidates and those that hire them, obtain a more informed appreciation for their realistic prospects. In this way, an achievable expectation should lead to more efficient placement behavior.     

Let’s Not Go Down that Path Again: Lessons from the Past Applied to Immigrant-Targeted Discrimination

Immigrants, both legal and illegal, are a staple of the modern United States workplace. While much of the discussion of this fact centers on negative consequences for the U.S., far less attention has been paid to the detrimental impact on immigrants resulting from their workplace experiences, particularly relating to being targets of discrimination. In this article, we outline: a) a variety of types of workplace discrimination potentially relating to immigrant status; b) potential negative outcomes arising from said discrimination for both immigrant employees and their employers, and; c) how existing and predicted employment law standards place organizations in a legally vulnerable position when such discrimination goes unchecked. We further discuss implications of immigrant-targeted discrimination (ITD) for organizations and managers, and plausible extensions of workplace discrimination laws to specifically include ITD.     

The future of the uplands

Upland areas provide UK society with many important functions, goods and services, but have experienced a number of disturbing trends and face an uncertain future. This paper outlines historic, current and future drivers of environmental, economic, socio-cultural and policy change in UK uplands, and assesses how these have affected or are likely to affect ways in which land is used and the provision of ecosystem services. Information is synthesised into scenarios summarising a range of possible futures anticipated for UK uplands to 2060 and beyond. Finally, innovations in science, technology, governance and policy are evaluated that could enable uplands to continue providing key ecosystem services under a range of scenarios. The paper concludes that many upland areas will need to be prepared for significant reductions in grazing and prescribed burning. Conversely, other areas could experience agricultural intensification, for example significant increases in grazing or an expansion of arable or bioenergy crops into upland valleys, due to anticipated increases in global demand for food and energy. These scenarios will take place in the context of climate change. Many may take place together and may interact with each other, with complex and unpredictable implications for the upland environment, economy and society. In this context, a number of advances are needed in science, technology and policy to maintain viable upland communities and the future provision of ecosystem services. These may include funding for ecological and hydrological restoration via carbon offsetting or other means. It may also involve advances in ecosystem service modelling, mapping and valuation, which through stakeholder participation could facilitate more integrated rural planning. New forms of environmental governance need to be explored that can empower those interested in developing upland economies to maintain thriving upland communities, while managing the ecosystem services they provide as efficiently as possible.
