Using survey forecasts of a large number of Asian, European, and South American emerging market exchange rates, we studied empirically whether evidence of herding or anti‐herding behavior of exchange‐rate forecasters can be detected in the cross‐section of forecasts. Emerging market exchange‐rate forecasts are consistent with herding (anti‐herding) if forecasts are biased towards (away from) the consensus forecast. Our empirical findings provide strong evidence of anti‐herding of emerging market exchange‐rate forecasters. 相似文献

This article is geared toward shedding some more light on what may be the next space race and its contours.Space flight is undoubtedly a human achievement of the second half of the 20th century, and probably the most audacious one of the past century. The space race started suddenly in the 1950s and has grown explosively during the following two decades, but decreased steadily after the 1970s. After the 1990s, however, we have seen a shy rebirth of space-related activities, when many other actors (states) entered the stage, adding up to the agonizing role of the two-actor piece that we have witnessed during the so-called Cold War.The opening years of the 21st century provided a more complex narrative for space exploration. At the start of the new millennium a new technosphere [1] emerged, dominated by what is used to be called as the Information and Communications Technologies (ICT), with the Internet playing the leading role among the bandwagon of technological novelties that appeared during the twilight of space activities. In despite of the fact that artificial satellites represent the very backbone of the global communications system, space activities seem to play a secondary role amidst the apparently accelerated rate of change concerning the technological systems of the present technosphere. But, as it is demonstrated in this paper, things are changing, and very probably a renewed space race will unfold in the coming decades.A question may be placed: what happened? Why the Earth stood still with regard to the race toward the cosmos? Answer: futurists, even prestigious ones like Herman Kahn and Arthur Clarke, did not consider the existence of socioeconomic long waves (Kondratieff waves, or K-waves for short) with their two decades long economic downturn, which has contributed to the deceleration of space-related activities.Analyzing the worldwide evolving scenario of space-related activities during the last eighty years under the framework of the succeeding K-waves and applying some technological forecasting tools, namely the logistic analysis, technological surveillance and intensive data mining, scrutinizing more than 7500 events occurred in the period 1930–2010 related with space activities, it is demonstrated that the space race like the one that we have witnessed until now is a natural growth process that has saturated at the dawn of this century. The same analysis demonstrates that a new growth process in this field might be nowadays under way with contours very different from that imagined by futurists and science fiction writers sixty years ago. Also the main trends in the usage of launching vehicles and satellites are framed and discussed in this paper. 相似文献

This paper investigates the causal impact of large unexpected windfalls on individual mental health, physical health, as well as health behaviors. I use a large individual-level panel data set of lottery winners from Germany between the years 2000 and 2011 and observe lottery winners before and after winning a large lottery prize. Mental health declines immediately after winning a large lottery prize for individuals with low education and low levels of financial literacy. While these individuals report being happier after winning the lottery, evidence from commonly used SF-12 measures of mental health indicates that winners with low education experience increased role limitations due to emotional problems, are more anxious, and have less energy after their win. The impact on various measures of mental health is highly robust, statistically significant, economically significant, and persists for up to two years after the win. Unexpected windfalls have no impact on the mental health of individuals with high education or high financial literacy. Winning the lottery has no impact on individuals’ health behaviors such as smoking or alcohol consumption, and it has no impact on doctor visits, hospital stays, or illness-related work absences regardless of education level. 相似文献

This paper studies the role of information about uncertain input prices for a competitive firm. The production decision has to be taken when the price of an input factor is perceived as random. However, a signal is observable in advance, conveying some information about the future factor price. Transparency is linked to the informational content of this signal. The impact of a higher level of transparency is analyzed from an ex ante perspective, i.e. before the information signal is observed. The change of factor use, production amount and cost are determined by comparing the strength of the curvatures of total and marginal product. By contrast, ex ante profit always increases, independently of the shape of the production function. 相似文献

We consider a one-sector growth model in continuous time with a production externality and endogenous labor supply. There is a continuum of households who have identical preferences but differ with respect to their initial wealth. We show that there exist economies such that an indeterminate steady state exists for some wealth distribution but not for others. A second result is that a redistribution of wealth may drive the economy from a steady state with strictly positive output to a poverty trap in which output converges asymptotically to zero. These results indicate that differences in the wealth distribution may be responsible for drastic differences in the long-run standard of living.

The aim of the present study is to examine the role of ethical dimensions and product personality in the purchasing intention of organic food products. The Prospect method (Caprara et al. in Test Psicomet Metodol 7(3–4):113–128, 2000), which integrates the Five factors model of personality (cf. Digman in Annu Rev Psychol 41(1):417–440, 1990) and the Theory of planned behavior (Ajzen in Organ Behav Hum Decis Process, 50(2):179–211, 1991) extended to an ethical dimension, was employed, by using a Structural Equation Modeling approach. Results showed that moral norms—i.e., personal beliefs regarding what is right or wrong (Parker et al. in Br J Soc Psychol, 34(2):127–137, 1995)—can be considered the main motivator of purchasing intention, and they are, in turn, affected by subjective norms and product personality traits of Naturalness and Authenticity. Marketing implications for firms operating in the organic food industry are discussed, in their intent to shift from a “niche” market to a broader diffusion of these products. 相似文献

Social group selection is explored as a scheme for the evolution of institutions giving rise to coordination and cooperation. Its crucial characteristic is the formation of psychic ties between group members which further the compliance with institutions by causing individuals to systematically underrate both the benefits of rule-breaking and the costs of rule-enforcement. With regard to the relationship between groups, these ties allow for the evolution of cooperation by enhancing selective forces acting between groups over those acting within. The resulting set of institutions represents a spontaneous order since neither perfect knowledge nor goodwill of any actor are required. 相似文献
