This paper investigates returns to women’s education by applying an optimal IV selection approach, post-Lasso IV estimation, which improves the first-stage predictive relationship between an endogenous regressor and instruments. Using the 2010 American Community Survey, we find that an extra year of education increases married women’s own income by $4,480 and spouse income by $8,822. Our findings indicate that 53% of the increase in women’s consumption by education is attributed to the marriage market, and thus, we conclude that the marriage market is the primary channel through which education improves women’s well-being. The results demonstrate the advantages of the post-Lasso approach: The resulting two-stage least squares estimator maintains efficiency without increasing finite sample bias and is less subject to the inconsistency problem when some instruments are invalid; This differs from the results using the instrument of birth quarters only, which is mostly applied in studies on returns to education. 相似文献

The global logistics industry has grown significantly and logistics has become an important sector of the business economic system and a major global economic activity in recent years. Logistics activities accelerate economic and productivity growth. Efficient logistics is also important to a country’s competitiveness and source of employment. The purpose of this paper is to uncover and understand the major determinants of logistics performance (LP) to further lift the LP of countries. Using unbalanced panel data of 93 selected countries from 2007 to 2014, the present research attempts to critically investigate the major determinants of LP. In estimating the model, this study prefers to use static panel data approach owing to limited data. The findings of the present study reveal that (a) countries with low level of corruption and stable political environment are likely to yield a high level of LP; (b) improvement in resources supply such as infrastructure, technology, labour, and education also have a significant positive effect on LP. Therefore, institutional reforms and upgrading resources will effectively accelerate LP. 相似文献

加快实施最严格水资源管理制度的重要目标是形成以节水为目标的新的社会运行机制和社会治理模式。农民在农业灌溉中自发形成的用水组织是这一变革中的重要社会力量。通过对农民用水协会特征的分析,认为在"水权配置"的视角下,发展与规范农民用水组织,变原有农业用水过程中的行政管控为社会治理,是建立农业"节水型"社会并支持其良好运行的重要保障,并就如何健全农民用水组织的内部治理结构、克服农民用水组织自身的消极因素提出了建议。 相似文献

The purpose of this research is to examine how consumers’ attachment to luxury restaurants and their emotional ambivalence contribute to their reservation session abandonment during the coronavirus disease 2019 (COVID-19) pandemic. In addition, the moderating effect of luxury consumption goals (e.g., self-presentation motives, status consumption, and need for uniqueness) is examined. A total of 408 participants completed questionnaires, and the results reveal that luxury restaurant attachment significantly influences consumers’ emotional ambivalence, which in turn causes them to not complete their reservation sessions. Furthermore, the moderating effects of status consumption and need for uniqueness are supported. 相似文献

在传统研发溢出效应假设基础上,通过技术差距将溢出效应与产品差异有机联系起来,并通过构建双寡头企业两阶段博弈模型对研发卡特尔、生产卡特尔、完全合作等不同形式合作联盟的均衡水平和福利变化进行分析比较。研究证实:当企业间技术差距较小时,完全合作或研发卡特尔能有效提高企业利润和社会福利;而当技术差距较大时,研发阶段的合作不仅无法激励企业进行研发投入,还会抑制企业创新的积极性。此外,与完全合作相比,局部合作具有更强的稳定性和可持续性,尤其是在产品差异程度较大的情况下,研发卡特尔最为稳定。 相似文献

企业边界人员与外部利益相关者发展私人关系是新兴市场中的普遍现象,但是“私人关系”是否真的会提升企业绩效?当前文献对此问题并未给出一致结论。文章基于105篇使用中国市场数据的中英文文献,运用元分析技术(Meta-Analysis)考察了私人关系对企业绩效的影响,并分析了企业所处的制度环境和市场环境,企业的生命周期、规模、所有制形式等内部特征对上述影响的调节作用。通过对392个效应值的集成分析,文章发现,尽管私人关系确实能提升企业绩效(r=0.167),但是不同层面的私人关系(政治联系和商业联系)对不同类型的企业绩效(财务绩效、运营绩效和战略绩效)所产生的影响存在差异。同时制度环境、市场环境、企业特征均会显著地调节私人关系对企业绩效的影响。上述结论为新兴市场中的企业如何将私人关系转化为企业绩效提供了指导。 相似文献

We exploit an influential 1991 Delaware court ruling to examine simultaneously two types of conservatism that play important roles in resolving creditor–owner agency conflicts: contracting conservatism and reporting conservatism. The ruling expanded managerial fiduciary duties in favor of creditors for Delaware-incorporated firms in the vicinity of insolvency. In those firms, following the ruling, debt contracts are less likely to include conservative adjustments to accounting numbers used for covenant compliance (i.e., contracting conservatism decreases), while public financial reporting becomes more conservative (i.e., reporting conservatism increases). The decrease in contracting conservatism is concentrated in firms that exhibit a greater increase in reporting conservatism, suggesting that reporting conservatism is more cost-effective in resolving agency conflicts. In addition, the substitution effect is more pronounced in firms facing greater business uncertainty and firms with greater board independence. 相似文献

Relative income gap is one of the most popular approaches for explaining the income–happiness relationship. We argue in this article that when people compare their incomes, they care about distributional fairness more than relative income disparity. It is difficult for us to explain China's income–happiness paradox if we simply compare the income gap and do not explore the income‐generation process leading to income inequality. We therefore employ an approach based on a responsibility‐sensitive theory of justice that decomposes individual income into fair and unfair components. As a proxy for distributional unfairness, unfair income is considered the main source of unhappiness. Using data from the Chinese Household Income Project survey, we find strong support for the negative relationship between income unfairness and happiness. We also find a significantly positive relationship between the relative income gap and income unfairness, which leads us to consider the income comparison hypothesis as the explanation for the income–happiness paradox in a new light. Sensitivity analyses confirm the robustness of our results. 相似文献

This paper examines the impacts of economic policy uncertainty and oil price shocks on stock returns of U.S. airlines using both industry and firm-level data. Our empirical approach considers a structural vector-autoregressive model with variables recognized to be important for airline returns including jet fuel price volatility. Empirical results confirm that oil price increase, economic uncertainty and jet fuel price volatility have significantly adverse effect on real stock returns of airlines both at industry and at firm level. In addition, we also find that hedging future fuel purchase has statistically positive impact on the smaller airlines. Our results suggest policy implications for practitioners, managers of airline industry and commodity investors. 相似文献
