Biodiversity and Optimal Policies Towards R&D and the Growth of Genetically Modified Crops

In this paper we provide a simple model illustrating the possible nature ofgovernment policy with regards to genetic modification, taking into accountits impact on the environment. We show that it is necessary not only tointervene in the growing of crops, but also to intervene in R&D througha tax on the adoption of new GM technology. Without intervention at bothlevels, both the cultivation of GM crops and the rate of innovation in GM willexceed their socially optimal levels.     

Good green mothers consuming their way through pregnancy: roles of environmental identities and information seeking in coping with the transition

We explore the consumption experiences of women who opt for an environmentally conscious approach to pregnancy. Our findings reveal that environmentally conscious mothers conduct extensive scientific research about the products that they purchase during pregnancy and the associated risks of using such products. They believe that their efforts to find and process such information make them experts on what is best for their babies’ health and proclaim some micromanaging powers in an uncontrollable environment. Alas, consumption decisions are simultaneously coupled with tensions between (1) needing to make informed choices and being overwhelmed with information; (2) feeling confident about seeking consumption information and lacking the confidence to share it; and (3) pursuing external expertise and resorting to internal instincts. Thus, although consumption is often perceived as a helpful coping mechanism when transitioning to new life roles, we find that it also contributes to the complexity of such transitional situations.     

Bargaining with imperfect enforcement

The game‐theoretic bargaining literature insists on a noncooperative bargaining procedure but implicitly assumes “cooperative” implementation of agreements. In reality, courts cannot implement agreements costlessly, and parties often prefer to use “noncooperative” implementation. We present a bargaining model which incorporates the idea that agreements may be enforced noncooperatively. We show that this has a substantial impact in limiting the inequality of agreements, and results in a nonmonotonicity of the discount rate. The model also explains why some parties may have incentives to deliberately write incomplete contracts as a way to enhance their bargaining power.     

The Political Economy of Energy Transitions: The Case of South Africa

This paper explores the political economy of energy transition in South Africa. An economic model based around a powerful ‘minerals-energy complex’ that has previously been able to provide domestic and foreign capital with cheap and plentiful coal-generated electricity is no longer economically or environmentally sustainable. The paper analyses the struggle over competing energy visions, infrastructures and political agendas in order to generate insights into the governance and financing of clean energy transitions in South Africa. It provides both a rich empirical account of key policy developments aimed at enabling such a transition and provides reflections on how best to theorise the contested politics of energy transitions.

Effect of emotional victim images in prosocial advertising: The moderating role of helping mode

Charities and marketers routinely incorporate images of recipients, for example victims of a flood or famine, in their prosocial advertising; however, previous literature suggests mixed results regarding the effectiveness of relying on sad versus happy images of victims. Recently, due to reactance to excessively traumatic marketing campaigns, happy victim images have been found to be more effective in eliciting prosocial behaviors. To extend this line of research, an experiment found that consumers are more willing to help when viewing advertisements featuring happy children over sad children. Moreover, helping mode moderates the relationship between victim image and helping intentions. The effect of a happy victim image is attenuated when consumers are asked to buy cause-related products rather than donate to charities. According to emotion regulation consumption theory, consumers mitigate the feeling of negative emotions by increasing their intention to buy cause-related products. Practically, the findings provide guidance on integrating victim images in prosocial advertising.     

Feasibility of routine collection of injured worker occupational information in hospital emergency departments

The aim of this study was to examine injury events and risk-factors among Swedish adult eventing athletes. A cross-sectional study design with retrospective recording of 1-year sports-specific exposure and injury data was used. The invited study population consisted of all members of the Swedish Equestrian Federation with eventing as their primary discipline (n = 513). The participation rate was 70.0%. The total 1-year injury prevalence was 26.6%; the specific 1-year prevalence of traumatic injury was 19.3% and of overuse injury 10.9%. The incidence of traumatic injury events was 0.54 injury events/1000 eventing hours (95% confidence interval (CI), 0.35–0.73 injury events/1000 eventing hours) for novices and 0.35 injury events/1000 eventing hours for qualified riders (95% CI, 0.21–0.49 injury events/1000 eventing hours). A total of 27.9% of the traumatic injury events led to severe injuries (causing more than 3 weeks absence from riding). Attitude to risk-taking was the only factor predicting an athlete becoming injured (p = 0.023), and qualification level was the only risk factor for additional injuries among injured riders (p = 0.003). Our results suggest that injury prevention programs in eventing should also give attention to overuse injuries and that care should be taken when eventing athletes are licensed into higher qualification groups.     

Tourism,Consumption and Inequality in Central America

Much research in international political economy (IPE) has been criticised for focussing on large and powerful actors in post-industrial countries, to the neglect of sites, processes and actors in the global South. This article offers a corrective to this bias in two ways: by locating the analysis in two rural Central American communities; and by exploring the social relations of consumption in these communities. In doing this, I challenge assumptions about rural places being excluded from global processes and explore the complexities and contradictions of how such communities are inserted into global circuits of production and consumption. Drawing on extensive qualitative research, the article explores the ways in which capitalist development through tourism has reconstituted the political economy of consumption in terms of habits, attitudes and behaviour in these two communities. Using the community and the household as sites of analysis, I explore the complex ways in which inequalities have been reconfigured through changing relations of consumption. Certain kinds of social hierarchies, in particular traditional gendered power relations within the household, have been challenged. However, other inequalities – such as class, ethnicity and nationality – have been reinforced by these processes.
