People’s responses to risks of electromagnetic fields and trust in government policy: the role of perceived risk,benefits and control

Trust in government policy affects the way people perceive and handle risks. In our study, we investigated the relationships between trust in government policy regarding electromagnetic fields (EMF), perceived risk and perceived benefits of public and personal EMF sources, perceived control over exposure to EMF and responses to the possible EMF health risk (e.g. protest against placement of mobile phone base stations or power lines, or taking own measures against EMF exposure). Previous research indicated that perceived risk and benefits mediate the relationship between trust and people’s risk responses. Additionally, we suggest that perceived control over EMF exposure affects the relation between trust in government policy and perceived risk, and, consequently, the risk responses. We performed a survey among the Dutch population (n?=?1009), which contained questions about risk responses to EMF, perceived risk and benefits of several EMF sources, trust in government policy and perceived control over EMF exposure. Comparing public EMF sources, i.e. power lines and mobile phone base stations, to personal EMF sources, i.e. microwave ovens and cordless and mobile phones, we tested our hypotheses. Variations in risk responses to both public and personal EMF sources were mainly explained by risk perception. In addition, perceived risk partially mediated the relationship between trust in government policy and risk responses. For public sources, perceived control over exposure weakened the negative relationship between trust and perceived risk. We conclude that, especially in people with low perceived control, a lack of trust in government policy may enhance perceptions of health risks, thereby increasing their inclination for risk responses.

Multivariate risks and depth-trimmed regions

We describe a general framework for measuring risks, where the risk measure takes values in an abstract cone. It is shown that this approach naturally includes the classical risk measures and set-valued risk measures and yields a natural definition of vector-valued risk measures. Several main constructions of risk measures are described in this axiomatic framework. It is shown that the concept of depth-trimmed (or central) regions from multivariate statistics is closely related to the definition of risk measures. In particular, the halfspace trimming corresponds to the Value-at-Risk, while the zonoid trimming yields the expected shortfall. In the abstract framework, it is shown how to establish a both-ways correspondence between risk measures and depth-trimmed regions. It is also demonstrated how the lattice structure of the space of risk values influences this relationship. I. Molchanov supported by Swiss National Science Foundation Grant 200020-109217.     

The effect of task-technology fit on purchase intention: The moderating role of perceived risks

Electronic commerce to date has experienced rapid growth, and online purchases have become very popular among online consumers. To successfully attract online consumers and benefit from doing so, e-tail product providers should learn about consumers’ purchase intention, its antecedents, and moderators. This study proposes a research model of purchase intention using perceived performance risk and perceived privacy risk as moderators based on a perspective of task-technology fit. In the proposed model, purchase intention is positively influenced by three antecedents: task-technology fit, perceived navigation, and perceived reputation. Each model path is moderated by perceived performance risk and perceived privacy risk, respectively. Empirically testing using a survey of 749 registered members (consumers) from the database of Taiwan’s largest e-learning commercial website confirms that task-technology fit, perceived navigation, and perceived reputation positively influence purchase intention. The relationship between task-technology fit, perceived navigation and purchase intention are significantly moderated by the perceived performance risk and perceived privacy risk. Finally, managerial implications and limitations of our findings are discussed.     

Determinants of risk behaviour: effects of perceived risks and risk attitude on farmer’s adoption of risk management strategies

The importance of risk perception and risk attitude for understanding individual’s risk behaviour are independently well described in literature, but rarely combined in an integrated approach. In this study, we propose a model assuming the choice to implement certain risk management strategies to be directly driven by both perceptions of risks and risk attitude. Other determinants influence the intention to apply different risk strategies mainly indirectly, mediated by risk perception and risk attitude. This conceptual model is empirically tested, using structural equation modelling, for understanding the intention of farmers to implement different common risk management strategies at their farms. Data are gathered in a survey completed by 500 farmers from the Flanders region in Belgium, investigating attitudes towards farming, perceived past exposure to risk, socio-demographic characteristics, farm size, perceptions of the major sources of farm business risk, risk attitudes and the intention to apply common risk management strategies. Our major findings are: (i) perception of major farm business risks have no significant impact on the intention of applying any of the risk strategies under study, (ii) risk attitude does have a significant impact. Therefore, rather than objective risk faced and the subjective interpretation thereof, it is the general risk attitude that influence intended risk strategies to be implemented. A distinction can be made between farmers willing to take risk, who are more inclined to apply ex-ante risk management strategies and risk averse farmers who are less inclined to implement ex-ante risk management strategies but rather cope with the consequences and diminish their effects ex-post when risks have occurred.     

Comparative optimism and risky road traffic behaviors among high‐risk sports practitioners

This study examines the relationship between participation in risky sports, comparative optimism (CO), and risky road traffic behaviors among a sample of adult men. We surveyed high‐risk (n = 313) and low‐risk (n = 53) sports practitioners, and non‐sportsmen (n = 89), assessing their CO, as well as their self‐reported risky behaviors and their accident experiences while driving a car. Results show that high‐risk sports practitioners expressed CO regarding the quality of their reflexes while driving and their vulnerability to traffic accidents. High‐risk sportsmen reported more risky behaviors while driving a car than the members of the other groups, and some of them, namely BASE‐jumpers, have experienced more traffic accidents. High‐risk sportsmen’s risky behaviors and accident experiences did not prevent them from expressing CO regarding their vulnerability to road accidents. Results are discussed, as well as putative psychological mechanisms underlying high‐risk sport practitioners’ CO and risky behaviors while driving.     

Effect of perceived risk on nuclear power plant operators’ safety behavior and errors

Safety behavior and human errors are major concerns for nuclear power plant operators. The present study investigated how nuclear power plant operators’ perceived risk influences the quality of their own work performance in terms of safety behavior and errors. In total, 349 operators from two nuclear power plants in China participated in the present study. We found that perceived risk had a negative linear relationship with safety behavior and a quadratic relationship with errors. Leader support played a moderating role in the relationships between perceived risk, safety behavior, and errors. These results supported the job demands–resources model and provided further evidence for the relationship between perceived risk and outcomes related to safety behavior and errors. Our findings suggest that an effective way to address the issue of high perceived risk is to provide a supportive environment.     

Influence of perceived risk on entrepreneurial desirability and feasibility: multidimensional approach for nascent entrepreneurs

This study examines the influence of perceived risk on entrepreneurial desirability and feasibility as determining factors in the intention to start a self-owned business. Specifically, a multidimensional approach is taken to examine the different types of risks associated with entrepreneurship: economic, social, time, health and personal risks. The results obtained from a sample of 376 new entrepreneurs in Mexico confirm the fact that the perceived desirability and feasibility have a significant and positive effect on the intentions to start their own company. On one hand, the empirical evidence obtained shows a heterogenic effect of the risk dimensions associated with entrepreneurship on the perceived desirability and feasibility in their behaviour. Therefore, it was found that the economic risk associated with entrepreneurship has a negative effect on the feasibility to start a business, but does not significantly influence the desirability of that behaviour. On the other hand, a significant effect from the risk related to health is not seen on desirability and feasibility, but the negative influence of personal risk is empirically supported for both variables. Finally, the results obtained related to social and time risk are contradictory. Social risk negatively influences entrepreneurship desirability, but a positive effect is observed on the feasibility to create a business. For its part, the empirical evidence obtained does not support any effect of the time risk on the perceived feasibility of starting a business, but there is a positive on entrepreneurship desirability. These results, which are contrary to the traditional concept of risk as a barrier to entrepreneurship, are justified by the vocational nature of this behaviour and by the social sacrifices that are sometimes necessary to be able to make a business work.
