We use a large non-student sample to test how distinct measures of risk-attitudes relate to each other, to demographic characteristics and to real-life risk taking in the financial domain. These measures, namely the Bomb Risk Elicitation Task (BRET), self-reported willingness to take risks in general, the choice in a hypothetical lottery, the score in the Domain Specific Risk-Taking (DOSPERT) scale, appear to be positively correlated and exhibit a certain degree of consistency. Furthermore, a subset of these measures is driven by similar demographic characteristics as such that males are more risk seeking and risk-aversion increases with age. Using extensive data on the retirement portfolios of the participants during the years 2008–2014, we find that all of these measures are positively correlated with the riskiness of individual portfolios. The self-reported willingness to take risks in general appears to be the most relevant measure in predicting actual risk-taking behavior.  相似文献

厉鹗作为浙派宗师,从其诞生至今三百多年来,引起了学者的广泛研究兴趣.其研究历程可分为三个阶段:生前至1911年是活跃期;1912年至1979年是沉寂期;1980年以后是繁荣期.在这些时期取得了一批重要的初步研究成果,但总的来说,研究的深度与广度与他在清代诗史上的实际地位极不匹配,我们期待对厉鹗的研究更加广泛和深入.  相似文献

We explore sustainable paths out of a debt trap with a highly stylized two-sector differential equations model for the stocks of money in Government and Society. The model fits the data for the U.S. between 1981 and 2012 with a coefficient of correlation of 0.996. The solutions provide detailed “escape conditions” from the debt trap. A primary surplus is required. Then a government can escape its debt trap either through sustained annual monetary outflows from society to the government (taxation) but with a low initial growth rate, or through annual monetary inflows into both sectors (stimulus) with higher initial growth rate. We illustrate the use of our model with simulations which show how five indebted countries can escape their debt trap in 30 (or 70) years.  相似文献

E.E.肯明斯是美国著名的先锋诗人。他的诗歌形式变异,语言分裂,在世界诗坛独树一帜。多年来,一些学者主要从他的语言和形式上探讨他的诗歌,认为他过分追求诗歌的形式,难免在主题上缺少应有的深刻度。但笔者认为,与其说肯明斯是用一种特立独行的方式与世界对话,倒不如说他标新立异的诗句正是他灵魂的投影,内心的独白。本文将依据文学批评的相关理论,探讨肯明斯诗歌的主题。  相似文献

Many claim that fluctuations in U.S. private savings help to create and to sustain global imbalances because of their influence on the current account deficit. To test this claim, this paper investigates the determinants of aggregate household savings using a panel of 18 developed countries for the period 1980–2005. We weave two strands of literature: the first strand from consumer theory, considering specifically the ‘wealth effect’, the second strand from aggregate private savings theory. The original contribution of this paper derives from the main explanatory variables of the household savings function: two measures of household wealth, the first a financial variable and the second a variable for tangible/housing stock. The salience of these variables has not been tested before. The model is then enriched with variables taken from the private savings literature. To find the best technique to estimate the long run savings function, unit root and cointegration tests are carried out, from which evidence of a cointegrating relationship is found. The group means FMOLS is used to estimate the model. The empirical evidence suggests effects consistent with theory: an increase in wealth negatively affects household savings. Furthermore, when important explanatory variables, such as government savings and population dependency ratios, are included in the model, tangible wealth becomes the only kind of wealth to (weakly and negatively) influence household savings in developed countries. In the U.S. however, wealth does not seem to affect household savings negatively, it seems instead that government savings and population changes better explain the decline of savings during the past two decades. This finding provides additional evidence on the issue of global imbalances, and suggests that the recent booms of the stock and the real estate markets should not be blamed for the decline in U.S. household and private savings.  相似文献

This paper shows that financial intermediation can influence fertility and labor allocation decisions by raising market wages. The increase in wages induces some households to abandon “traditional” labor intensive methods of production managed at the household level and supply labor to “modern” sector firms. Since it is optimal for households in the modern sector to have fewer children, the labor allocation decision leads to lower national fertility. A panel VAR using financial intermediation, fertility and industrial employment share data in 87 countries is estimated. The empirical results show that the data are consistent with the theoretical predictions. Received: 20 October 1997/Accepted: 31 August 1998  相似文献

Adaptation of agricultural and industrial research and development models offers new methods for bridging the worlds of research and practice in child and youth services. Social R & D methodologies provide effective means for generating new social technologies because they are product oriented and use a wide array of traditional and nontraditional data sources. This article discusses one social R & D paradigm—Developmental Research and Utilization. Permanency planning and community support systems research are used to illustrate the past and potential application of this methodology to the field of child and youth services.  相似文献
