Does sports activity improve health? Representative evidence using local density of sports facilities as an instrument

Using representative and geocoded data from the Swiss Household Panel and the Swiss Business Census, we estimate the effect of sports activity on health. OLS models show that sports activity significantly decreases overweight, sleeping problems, headaches, back problems, and perceived health impediments in everyday activities and significantly increases health satisfaction. Because sports activity is likely to be misreported and correlated with unobserved determinants of health, we use the number of sports facilities within 6 miles of the individual’s residence as an instrument for sports activity. Although the instrument is powerful in explaining sports activity, the second-stage effects on health are mostly statistically insignificant due to the high SEs of the IV estimates.     

农民地位代际流动何以可能?——农民市民化水平对子女教育期望影响的实证研究

从农村教育发展来说,其模式是城市化的,但是农民自身并没有实现市民化。这使得农村教育模式与农村教育对象之间表现出了较为明显的不相适应性,这是当前我国农村教育问题丛生的根源所在。实现农民的市民化,使其能够更好地适应现有的具有城市化特征的农村教育模式是农村教育的一条出路。通过建立Logistic回归模型,研究农民的市民化水平对子女教育期望的影响。文化资本层面的市民化水平变量最能解释农民对子女教育期望的差异,其次是经济资本层面的市民化水平变量,社会资本层面的市民化水平变量的解释能力最弱。     

Effects of a holiday trip on health and quality of life: evidence from a natural experiment in South Korea

We examine whether having a holiday trip affects an individual’s well-being, namely quality of life, health status, stress level and health behaviours. We use the two-stage estimation method to control for endogeneity of a travel experience, exploiting a natural experiment of distributing Travel Vouchers at random among qualified applicants in South Korea in 2012. We find that, for applicants whose decision to travel is influenced by receiving a voucher, a travel experience has no significant effects on the traveller’s well-being measured 3–12 months later. We also find that the OLS estimates overstate benefits of a travel.     

社会资本影响农村中小企业正规信贷可得性的实证分析——基于福建省350个样本的调查

针对我国农村中小企业正规信贷融资难的问题,本文基于2008年福建省农村350家中小企业的调查数据,采用Logistic回归模型,对企业主社会资本对农村中小企业正规信贷可得性的影响进行了实证分析。结果表明:网顶、熟人信任、贷款认知性3个因子对农村中小企业正规信贷可得性具有显著的正向影响;普遍信任、规范2个因子对农村中小企业正规信贷可得性具有显著的负向影响;网络规模、特殊信任2个因子对农村中小企业正规信贷可得性没有显著影响。     

You Are What You Eat: The Social Economy of the Slow Food Movement

Recent work by Schor revives concerns raised by Veblen and Hirsch over the destructive consequences of competitive consumption. In contrast, Twitchell argues that increased access to commodities as symbols of luxury signals a democratization of class and social status. Rather than playing the role of dupes, consumers are active co-conspirators in the creation and maintenance of luxury goods markets. While flawed, each of these perspectives has something important to offer to social economists interested in understanding consumption. A key question for social economists is whether material pleasure and the symbolic expression of identity through consumer goods is compatible with a more politicized, socially conscious consumption ethos. Food consumption offers a fruitful starting point for pursuing this issue. I begin by examining food and its symbolic role in identity formation. I then consider the Slow Food movement and explore the ways in which it maintains a central role for material pleasure while promoting a socially and environmentally conscious stance toward consumption.     

异质性信息对淡水养殖户采纳两型生产技术的影响——以社会网络为工具变量的实证检验

本文为比较不同类别信息对淡水养殖户采纳两型生产技术的影响效应,在对农户采纳技术行为进行理论分析的基础上,构建以社会网络作为工具变量的回归模型.结果表明,①获取技术信息对农户采纳两型农业技术有显著的促进作用,在不考虑技术信息内生性的情况下,获取技术信息的影响会被低估;②不同类别信息对农户采纳两型农业技术的影响程度不同,获取技术使用信息对农户采纳两型农业技术的影响程度大于获取技术市场信息.在使用信息中,操作信息比经验信息对农户采纳技术的促进作用更大;在市场信息中,价格信息比质量信息对农户采纳技术的促进作用更大.     

A New View on the Economic Theory of the State: A Case Study of France

Given the contribution of Schumpeterian entrepreneurship to technological progress and well-being, the accuracy of investment decisions by venture capitalists is a societal issue. Venture capitalists find the human capital of entrepreneurs difficult to assess. This paper employs instrumental value theory to assess the impact of different human capital factors on the performance of new ventures. A meta-analysis of 29 previous empirical studies that examined the effect of founder's human capital on new venture performance suggested that instrumental value theory holds promise as a guide for research on entrepreneurs' human capital and new venture performance. It could also help venture capitalists to make better investment decisions, benefiting society in general.     

The true effect of students’ employment on the duration of studies

We examine the effect of the first-degree students’ employment on the prolongation of their studies. When employing a popular instrumental variable, the regional unemployment rate, we find a negative impact of students’ employment on duration of studies. Then, adding a predetermined IV – the individual’s employment prior to the beginning of academic studies – turns the estimate positive. Furthermore, we find that the relationship between the extent of students’ employment and duration of their studies depends on their age: among the younger students (aged 22–26), the extent of employment has no effect on the duration of studies, while among the older students, the effect is positive and statistically significant.     

企业家社会资本对文化企业财政支持可获性的影响——基于江苏省文化企业调研数据的实证研究

财政支持是影响文化企业发展的重要政策因素.文章首先将企业家社会资本分为企业家政治关系资本和企业家商业关系资本 ,在此基础上使用178家江苏地区文化企业实地调研数据 ,构建计量经济模型实证检验了企业家社会资本对文化企业财政支持可获性的影响.研究结果发现:企业家政治关系资本对文化企业财政支持可获性具有正向影响 ,但在统计上不显著;企业家商业关系资本对文化企业财政支持可获性具有显著正向影响 ,且企业家商业关系资本的作用明显大于企业家政治关系资本 ,这表明地方政府在决定是否对文化企业给予财政支持时 ,明显淡化了以往侧重于通过行政权力主导补贴资金的传统做法 ,而更多地遵循了通过市场机制来配置公共财政资源的原则.     

家族企业成长的社会网络资本

家族企业的突出特征表现为家族对企业所有权和经营所有权的控制,按照一般的发展顺序,家族企业的成长过程可依次划分为原始家族企业、纯粹家族企业、泛家族企业和现代家族企业4个阶段。伴随着家族企业的成长而变化和延伸的是家族企业自身所拥有的一种具有商业性质的资本,即社会网络资本。本文主要探讨社会网络资本伴随家族企业成长4阶段而发展变化的轨迹和规律性,以充分利用这种特殊资本来促进家族企业快速发展。     

新员工主动社会化行为与组织承诺关系研究——以社会资本为中介变量

为了探索新员工主动社会化行为影响组织承诺的过程,本文对来自企业的401个有效样本进行了实证分析。本研究运用层级回归的方法,控制了人口统计变量的影响后,发现员工的搜寻信息和搜寻绩效反馈行为对组织承诺有直接的正面影响,同时,通过员工社会资本对员工组织承诺产生了间接的正面影响。社会资本在员工搜寻信息和搜寻绩效反馈行为影响组织承诺的机制中起部分中介作用。员工的关系构建行为对组织承诺没有显著影响,但对员工社会资本存在显著的正面影响。     

Do foreign institutional investors enhance firm innovation in China?

This paper investigates the impact of the Qualified Foreign Institutional Investor (QFII) scheme regulated by the Chinese government on firm innovation in China. By explicitly addressing the potential endogenous relationship between foreign institutional ownership and firm innovation, we find that foreign institutional investors enhance firm innovation in China, suggesting that the Chinese government should further relax its foreign capital investment control, for example, increase the quota of the QFII scheme.
