We investigated three assortative matching forms, positive assortative matching, women marrying up and men marrying up, and their effects on household commercial insurance participation, the number of family members with commercial insurance and household premium expenditures. Men marrying up has a significantly positive effect on the possibility of household commercial insurance participation and the number of family members having commercial insurance. The effect of men marrying up is larger in health insurance than in life insurance and annuity due to the salience of health risks. Finally, men marrying up interacts with the gender and risk attitude of the household financial decision-maker and may jointly affect household commercial insurance participation. Female decision-makers in marriages are more likely to purchase commercial insurance. 相似文献

We consider marriage markets with externalities. We focus on weak externalities, that is, markets in which each agent is primarily concerned about her partner. We formalize and prove the claim that weak externalities are not so significant in the marriage market: in this case, the ω-core and the α-core coincide and are both nonempty. In addition, we show that, if we allow agents to block matchings without changing their mate, the results do not longer hold. 相似文献

研究目的:基于2015—2020年浙江省德清县与广东省南海区的城乡建设用地市场交易数据,实证分析产权的市场分割效应,定量测度城乡建设用地市场一体化水平并进行对比分析。研究方法:OLS回归,时空地理加权回归,倾向得分匹配与相对价格法。研究结果:(1)产权的市场分割效应显著且存在地区差异,集体产权在南海区正向影响建设用地价格,而在德清县反之;(2)地区间城乡建设用地市场一体化进程不一,集体建设用地市场发育更为成熟的南海区城乡建设用地市场一体化水平为1.707,相较于德清县的0.880领先;(3)同一地区不同区域的城乡建设用地市场一体化水平也存在分化,集体经营性建设用地以异地调整入市为特色的德清县相较于政府整备入市的南海区城乡建设用地市场一体化的内部差异更小。研究结论:产权依旧是城乡建设用地市场一体化面临的主要制度性壁垒,不同地区及其内部城乡建设用地市场一体化分异明显。未来在深入推进土地权利权能平等,改善集体建设用地区位劣势的同时,也需进一步关注城乡建设用地市场一体化在区域协调发展中的作用。 相似文献

Modern cooling technologies that utilize renewable energy sources have been increasingly recognized as promising tools to address various challenges emerging in progressively complex agrifood systems in developing countries. Knowledge gaps about the actual impacts of these technologies in developing countries remain, especially in Africa south of the Sahara (SSA). This study fills this knowledge gap by providing evidence from the evaluation of recent interventions in northeast Nigeria in which seven small solar-powered cold storages were installed across seven horticulture markets. Combinations of difference-in-difference (DID) and variants of propensity-score-based methods suggest that cold storage significantly increased horticulture sales volumes and revenues of market agents. Back-of-the-envelope calculations indicate that increased net revenues for market agents may be sufficiently large to recoup cold storage investments and operating costs within a reasonable time frame. Using cold storage also reduced the share of food loss. It lengthened the products' shelf-life while raising prices received by market agents and farmers, which were associated with improved product quality, expanded value-adding activities by market agents, and increased use of advance payments. 相似文献

We embed skill obsolescence and endogenous growth into a New Keynesian model with search-and-matching frictions. The model accounts for key features of the Great Recession: the “productivity puzzle” and the “missing disinflation puzzle.” Lower aggregate demand raises long-term unemployment and the training costs associated with skill obsolescence. Lower aggregate employment hinders learning-by-doing, which slows down human capital accumulation, feeding back into even fewer vacancies than justified by the demand shock alone. These feedback channels mitigate the disinflationary effect of the demand shock while amplifying its contractionary effect on output. The temporary growth slowdown translates into output hysteresis. 相似文献

随着中国企业对外直接投资(OFDI)规模的日益扩大,企业OFDI对企业生产能力的影响问题成为学者们研究的重点议题.本文基于2013—2018年的企业OFDI数据,使用倾向得分匹配法系统研究对OFDI活动对中国企业生产能力的作用结果.研究发现:OFDI活动与企业生产能力之间存在着显著的因果关系.不论是从短期还是长期来看,OFDI活动都会对企业的生产能力产生正向推动作用,同时这种推动作用还会随着时间的推移而不断提高.另外,本文还将OFDI活动划分为三大类,不同类型的OFDI活动对企业生产能力的影响中存在着较为显著的差异性.本文的研究结论为推动中国企业开展OFDI活动及相关政府管理部门制定管理政策,提供了重要的参考和借鉴. 相似文献
