1871 saw the publication of two major treatises in economics, with self-seeking economic man at their center. In the same year Darwin published The Descent of Man, which emphasized sympathy and cooperation as well as self-interest, and contained a powerful argument that morality has evolved in humans by natural selection. Essentially this stance is supported by modern research. This paper considers the nature of morality and how it has evolved. It reconciles Darwin’s notion that a developed morality requires language and deliberation (and is thus unique to humans), with his other view that moral feelings have a long-evolved and biologically-inherited basis. The social role of morality and its difference with altruism is illustrated by an agent-based simulation. The fact that humans combine both moral and selfish dispositions has major implications for the social sciences and obliges us to abandon the pre-eminent notion of selfish economic man. Economic policy must take account of our moral nature. 相似文献

We revisit the meta-analysis of Sheremeta on overbidding in contest experiments and focus on the effect of endowment on overbidding. Sheremeta assumes, and finds evidence of, an increasing linear relationship between endowment and overbidding, Quantal Response Equilibrium (QRE) predicts an increasing concave relationship, while Baik and colleagues find an inverted U-shaped relationship in their analysis of a single experiment. We use the same data as in Sheremeta, but employ a different econometric model which leads to support for both QRE and the inverted U-shaped relationship. Following Baik and colleagues, we posit that the inverted-U relationship may be interpreted in terms of a wealth effect. 相似文献

Helping behavior in a virtual crisis situation: effects of safety awareness and crisis communication
Incident evaluations show that bystanders tend to help: they do not wait for professionals to arrive, but act as required by the situation at hand. In the present study, we investigated how safety awareness (induced before an accident happened) and providing a course of action by emergency services affect helping behavior after witnessing a virtual accident with two victims. The main task of the participants was to arrive at a job interview in time. Safety awareness was manipulated by the specific organization they went to: either promoting safe traffic or healthy living. The results show that all participants were inclined to help. Participants who were primed towards safe traffic more often called the emergency number, but talked to the victim less often. Participants who had received specific courses of action moved the victim less often. In all, the results clearly indicate the value of effective risk communication (before an event occurs) and crisis communication (after an event has occurred), as both types of information improve the quality of actual helping behavior at the scene. 相似文献

In the summer of 2014 Germany will witness the most substantial expansion of pension expenditures since the 1950s. Yet, while this reform package was motivated mainly by the dismal prospect of rising old age poverty rates, it does little to alleviate this problem. On the contrary, its two central elements, an expansion of the pension claims of mothers whose children were born before 1992, and access to early retirement at age 63 for workers with a long insurance history, tend to benefit rather privileged groups of the insured. These measures endanger the sustainability of the German pension system and will necessitate future generations to work even longer than would have been the case otherwise. 相似文献

This study examines the perceptions of local residents prior to the 2014 Sochi Olympic and Paralympic Games. A survey conducted amongst residents, 5 months prior to the Games opening, reveals a lower level of support for the Games during the preparation period compared to other Olympic host cities. Socio-demographic data about the residents help explain the varying attitudes towards the Games that were identified. The conclusions suggest that Sochi residents’ perceptions have been largely influenced by their thoughts regarding potential economic and socio-cultural impacts, whether positive or negative. When these opinions are analysed further, three main considerations were found: (1) impacts on urban development and quality of residential life; (2) positive impacts on tourism and the destination’s economy and (3) negative results of hosting the Games. The study also finds, using structural equation modelling, that residents of Sochi, who could receive some benefit from the Games, were involved in the decision-making process or had more information about the upcoming Games, demonstrated more positive attitudes towards hosting the Olympics. 相似文献

This literature review analyzes the global phenomenon of international project finance (PF) as both a management and finance instrument, allowing practitioners to realize large scale infrastructure projects in high risk contexts. After describing the characteristics of PF, its historical origins and its unique benefits for empirical inquiry, I summarize the findings of academic research from an interdisciplinary perspective. Based on this integration of Finance, Management and International Business research, I discuss the theoretical implications for each field that emanate from PF. Finally, I identify possibilities for future research and propose a more balanced, interdisciplinary academic treatment of PF. 相似文献

In this paper, we provide an intensive review of the recent developments for semiparametric and fully nonparametric panel data models that are linearly separable in the innovation and the individual-specific term. We analyze these developments under two alternative model specifications: fixed and random effects panel data models. More precisely, in the random effects setting, we focus our attention in the analysis of some efficiency issues that have to do with the so-called working independence condition. This assumption is introduced when estimating the asymptotic variance–covariance matrix of nonparametric estimators. In the fixed effects setting, to cope with the so-called incidental parameters problem, we consider two different estimation approaches: profiling techniques and differencing methods. Furthermore, we are also interested in the endogeneity problem and how instrumental variables are used in this context. In addition, for practitioners, we also show different ways of avoiding the so-called curse of dimensionality problem in pure nonparametric models. In this way, semiparametric and additive models appear as a solution when the number of explanatory variables is large. 相似文献

This paper replicates the results in Schularick and Taylor (American Economic Review 2012; 102 (2): 1029–1061; ST hereafter). Specifically, I replicate ST's results in the ‘narrow’ sense by reproducing their calculations in the open source econometrics package gretl. (Gretl is an acronym for Gnu Regression, Econometrics and Time‐series Laboratory. It is available for Windows, Mac and Linux at www.gretl.sourceforge.net .) I also demonstrate the robustness of ST's findings to different estimation methods. I obtain qualitatively similar results to ST via Bayesian estimation of both static and dynamic panel probit models. Finally, I show that the marginal effects of credit growth on the probability of a financial crisis vary considerably across the countries in the dataset. Copyright © 2016 John Wiley & Sons, Ltd. 相似文献
