This longitudinal study explored the relationship between perceived breast cancer risk and worry. We measured both absolute and comparative risk perceptions, and also used the Gail algorithm to assess the accuracy of participants' risk perceptions. Three hundred and one women ages 40–75 participated in a two‐part study assessing how format of breast cancer risk presentation affected perceptions of risk. Relative to their Gail scores, women were biased pessimistically about their own absolute breast cancer risk and yet largely accurate about their comparative breast cancer risk. Perceived comparative risk, but not perceived absolute risk or biases in absolute or comparative risk, predicted subsequent worry. Worry predicted subsequent perceived absolute risk and biases in absolute and comparative risk. These results suggest that women's emotional reactions to breast cancer risk are based on accurate (unbiased) perceptions of their comparative risks. In turn, greater worry prompts a re‐evaluation of absolute risk as well as changes in risk biases. Implications for screening are discussed.  相似文献

Theoretically based on the Haavelmo theorem, this study analyses the economic effects that increasing public expenditure or reducing public income have on the gross domestic product of Germany, with the help of two medium-sized macro-econometric models, the RWI business cycle model and the Econometric Model of the German Economy. The major finding is that most of the public revenue multipliers are considerably lower than most of the public spending multipliers. However, both the dimension and the time course of the effects are a function of the specific kind of politico-economic measures taken by the government.  相似文献

This article presents new estimates for investment and new growth accounts for three socialist economies between 1950 and 1989. Government statistics reported distorted measures for both the rate and the trajectory of productivity growth in Czechoslovakia, Hungary, and Poland. Researchers have benefited from revised output data, but have continued to use official statistics on capital input, or estimated capital stock from official investment data. Investment levels and rates of capital accumulation were much lower than officially claimed and over‐reporting worsened over time. A setback in factor accumulation—both investment in equipment and labour input—contributed very significantly to the socialist growth failure of the 1980s.  相似文献

This paper estimates the Heckscher–Ohlin model with annual US data from 1949 to 2006 for outputs of manufactures and services with inputs of fixed capital assets and the labor force. Difference equation and error correction regressions provide estimated coefficients for the comparative static system. Tariffs on manufactures primarily raise the capital return in the estimated Stolper–Samuelson results. Factor price equalization does not hold for labor and capital. Inverting the estimated system inverse matrix provides evidence on production. The suggestions are capital biased production of manufactures, strong substitution of capital for labor, and strong labor substitution in manufactures.  相似文献

This paper deals with consumer coping strategies when consumers experience difficulties in implementing an innovation. The particular setting for exploring this issue is a group of consumers in Michigan who are committed to eating local. The paper explores how these consumers cope or balance their commitment to eating local with the constraints they face on buying and preparing local food Following a literature review of coping strategy and consumer coping strategies in relation to innovations, the paper presents the results of three focus groups conducted with members of a Student Organic Farm, a food cooperative and a Slow Food Convivium. The consumers we interviewed mostly adopt problem‐centred, confrontative strategies: they change their food‐consumption habits including shopping, purchasing, cooking, storing and obviously, eating. None of these changes are easy to implement, and most require re‐allocations of time as well as trade‐offs to overcome time and cost barriers. In return, some of these consumers feel empowered. This study allows us to offer a working hypothesis that the process is dynamic: the more committed consumers are, the more they adopt problem‐centred, confrontative strategies and forget more fatalist emotion‐centred or avoidance strategies. These findings contribute to literature on consumers' coping strategies and suggest future research avenues.  相似文献
