Dynastic Inequality Compared: Multigenerational Mobility in the United States,the United Kingdom,and Germany

Using harmonized household survey data, we analyze long‐run social mobility in the United States, the United Kingdom, and Germany, and test recent theories of multigenerational persistence of socioeconomic status. In this country comparison setting, we find evidence against a universal law of social mobility. Our results show that the long‐run persistence of socioeconomic status and the validity of a first‐order Markov chain in the intergenerational transmission of human capital is country‐specific. Furthermore, we find that the direct and independent effect of grandparents' social status on grandchildren's status tends to vary by gender and institutional context.     

Representatives of future generations as promoters of sustainability in corporate decision processes

Current protests of the young generation emphasize that interests of future generations should be taken more into account by policy makers and in corporate decision processes. As organizations contribute to enduring environmental and social problems, they are required to promote sustainability in order to preserve options for the well-being of future generations. However, organizational decision makers often take a short-term perspective and neglect investments in intergenerational justice. Previous theoretical work has acknowledged the importance of representing future generations in today's decision-making processes to adopt a long-term perspective in order to promote intergenerational justice. In a laboratory experiment, we show that appointing representatives of future generations at the organizational level can foster investments in intergenerational justice. Although this outcome is more pronounced when aligned with the representatives' individual incentives, it even persists for a representative who is monetarily penalized for advocating the interests of future generations.     

Medical innovation and its diffusion: Implications for economic performance and welfare

We study the impact on economic performance and welfare of medical innovations and their endogenous diffusion. We construct a general equilibrium model with a medical sector and overlapping generations subject to endogenous mortality and calibrate it to reflect the development of the US economy and health care over the cardiac revolution during the 1980s and 1990s. By counterfactual analysis we find that (i) medical innovations have increased welfare without compromising GDP growth; (ii) there is a sizeable welfare loss due to the adoption lag involved with imperfect diffusion; and (iii) there is scope for Pareto improvement by way of subsidization of innovative health care.     

浅析虚无主义思想的历史逻辑

虚无主义是人对现实世界不断否定、批判达到的逻辑后果。它不仅包括哲学对现实世界的否定、批判而造成的世界的虚无化,也包括哲学在否定之后于"虚无"之上重建"真实世界"的努力。西方哲学与虚无主义存在一定的历史关联,在这种紧密的关联中,虚无主义依据内在逻辑不断演进。     

欧盟碳期货风险量化——基于GED-GARCH模型和VaR模型

以欧盟碳期货合约为研究对象,针对其反映的市场风险特点,采用GED-GARCH模型进行参数估计。结果显示:到期日的因素使得欧盟碳期货合约收益率序列的条件方差与历史信息之间存在联系;碳期货合约的到期日越久,其条件方差越依赖于历史信息,表明欧盟碳期货市场为弱式有效市场;欧盟碳期货合约收益率序列的波动会逐渐衰减,表明最终合约价格能够起到价格预示作用。再利用GARCH模型的参数估计结果,计算出不同置信水平下收益率序列的在险值,夯实实证研究结果。针对欧盟碳期货合约风险的量化研究表明,欧盟碳期货与碳现货的关系呈现出新兴市场的分割局面特征,进一步导致欧盟碳金融市场逐渐走向虚拟化。因此,在中国碳市场的建设中,应做到碳期货与碳现货交易相协调,做好碳金融市场上风险的量化和控制。     

Structural Changes in the Labor Market and the Rise of Early Retirement in France and Germany

The rise of early retirement in Europe is typically attributed to the European system of taxes and transfers. A model with an imperfectly competitive labor market allows us to consider also the effects of bargaining power and of matching efficiency on pre‐retirement. We find that lower bargaining power of workers and declining matching efficiency have been important determinants of early retirement in France and Germany. These structural changes, combined with early retirement transfers and population aging, are also consistent with the employment and unemployment rates, labor share and seniority premia.     

An emerging tourism planning paradigm? A comparative analysis between town and tourism planning

This article examines the roots and the evolution of tourism and town planning theory and practice. It discusses how both fields have interacted with each other, and provides some clues about the way in which tourism and town planning theory and practice are likely to evolve in the future. It is argued that tourism planning theory is still looking for its own identity and ways of evolving in the future. Copyright © 2001 John Wiley & Sons, Ltd.

情感型领导对员工工匠精神的跨层影响——基本心理需求满足和未来工作自我清晰度的作用

工匠精神作为企业实现提质增效、构建竞争优势等目标的关键推手,如何有效培育组织成员工匠精神成为学界和业界共同探讨的话题。基于自我决定理论,构建了一个包括情感型领导、基本心理需求满足、未来工作自我清晰度和员工工匠精神的跨层次有调节的中介作用模型。通过双时点方式收集数据并进行实证分析,结果表明：情感型领导对员工工匠精神培育具有积极影响;情感型领导通过基本心理需求满足间接影响员工工匠精神;未来工作自我清晰度不仅正向调节情感型领导、基本心理需求满足与员工工匠精神间关系,而且正向调节基本心理需求满足的中介作用。本文厘清了情感型领导与员工工匠精神间的内在机理,也为组织有效培育员工工匠精神提供了指导。     

韩国航天科技发展动因、现状与未来走向

运用层次分析法从国际、地区、国家3方面分析韩国加速航天科技发展的原因。根据相关机构数据,分析当前韩国航天科技的发展现状,认为韩国已建成相对完备的航天设施,具有自主研发、本土发射的基本条件。但与先发展起来的航天大国相比,其航天科技还有一定差距。研究认为韩国将继续加速推进航天事业发展,开发多样化、实用型的航天项目,加强自主研发的同时重视国际合作,积极发挥民营企业作用,推动战略性航天产业发展。
