The psychometric paradigm has identified two classic dimensions, dread and unknown risk, structuring the perception of risks. We propose that disputed risk and morality are two additional dimensions that are relevant to describe the cognitive representation of societal risks. Disputed risk captures two aspects of a societal risk: first, that consensus about scientific evidence is low, and second, that the public debate about the risk issue is highly controversial. Morality refers to judgments of reprehensibility, capturing the fact that societal risks frequently involve violations of moral principles. In a survey study employing two samples, a household sample (N = 418) and a student sample (N = 88), participants evaluated 24 societal risks on 23 psychometric scales intended to assess the four constructs dread, unknown risk, disputed risk, and morality. Principal component analyses yielded three dimensions: a common dimension of dread and morality, a disputed risk dimension, and unknown risk. We also assessed judgments of overall riskiness for all risks. Morality and dread both proved to be strong and distinctive predictors of perceived overall riskiness in regression analyses; disputed risk and unknown risk, in contrast, do not play a substantial role as predictors. These findings were replicated across both samples. We conclude that disputed risk constitutes a novel and unique psychometric dimension; morality, on the other hand, coincides with dread in the cognitive representation of societal risks, while still showing a distinct and strong effect in the prediction of risk judgments. 相似文献

This study examines the cognitive processes underlying investors’ extrapolations of past fund performance and whether investors’ attention patterns may explain their return-chasing behaviors. We measured the attention that investors paid to mutual fund disclosures in a simplified fund prospectus using unobtrusive infrared eye tracking. Results suggest that prior fund performance, which is normatively irrelevant information and not useful in predicting future performance, received considerable attention from investors. More interestingly, the impact of prior fund performance on investors’ purchasing intentions was fully mediated through expected returns and attention paid to past performance information. The results indicate that investors apparently believe in performance persistence or in a ‘hot hand’ effect, and that mutual fund purchases are driven by salient information such as superior performance. Moreover, we tested the disclaimer mandated by regulatory bodies, which warns that past performance does not guarantee future results. We found that the disclaimer was ineffective in reducing investors’ extrapolation biases, despite the fact that the disclaimer was attended to and properly encoded by investors. 相似文献

We examine the macroeconomic effects of bidding for the Olympic Games using panel data for 188 countries during the period 1950–2009. Our findings confirm that economies react to news shocks: investment, consumption, and output significantly increase 9 to 7 years before the actual event in bidding countries. Hosting countries also experience significant increases in investment, consumption, and output 5 to 2 years before the hosting of the Games. Mapping the Olympics into a macroeconomic model, we show that we can match our empirical findings if we assume that an Olympic bid represents news about increases in government investment. 相似文献

We analyze optimal procurement mechanisms when firms are specialized. The procurement agency has incomplete information concerning the firms' cost functions and values high quality as well as low price. Lower type firms are cheaper (more expensive) than higher type firms when providing low (high) quality. With specialized firms, distortion is limited and a mass of types earns zero profits. The optimal mechanism can be inefficient: types providing lower second‐best welfare win against types providing higher second‐best welfare. As standard scoring rule auctions cannot always implement the optimal mechanism, we introduce a new auction format implementing the optimal mechanism. 相似文献

We use a representative survey of the Turkish household sector and investigate factors impinging on saving-borrowing behavior. We run four probit regressions to elucidate (i) the saving decision, (ii) asset choice or portfolio composition for those who save, (iii) the bank loan decision and lastly (iv) the formal versus informal borrowing decision. We find income, education, marital status and region within country strongly correlate with those decisions. We offer some insights regarding the influence of variables like rural to urban migrant status and religious belief on saving and borrowing decisions. We discuss the long-term implications of our findings on the Turkish household savings performance. 相似文献

Equilibrium models have been widely used in the literature with the aim of showing theoretical properties of emissions trading schemes. This paper applies equilibrium models to empirically study permit prices and to quantify the permit price sensitivity. In particular, we demonstrate that emission trading schemes both with and without banking are inherently prone to price jumps. 相似文献

Products with a superior environmental performance, such as a high level of energy efficiency, are typically subject to information asymmetries. Therefore these product attributes are often undervalued in purchase decisions. Signaling, e.g. energy labeling, can overcome these asymmetries, with positive implications for effective consumer decisions, competitive advantage for suppliers of energy‐efficient goods, and for societal goals such as mitigating climate change. However, there is a scarcity of research investigating how energy labels actually influence consumer choice. The recent revision of the European Union energy label provided a unique opportunity to investigate the effectiveness of energy labeling in a quasi field‐experimental setting. We show that the proposed extension of the seven‐point A–G rating scale by adding new classes A+, A++, etc. will result in a lower perceived importance of energy efficiency in consumer decision‐making. Based on a stated preference survey investigating 2244 choices by German consumers, we conclude that the revision actually undermines the label's ability to overcome information asymmetries, hence potentially contributing to market failure.
