The effects of credit default swaps on corporate investment

ABSTRACT

This paper examines how credit default swaps (CDS) affect the corporate investment of the referenced entities. We document a significant reduction in corporate investment after CDS trading, a result that is robust to alternative model specifications and a set of endogeneity tests. Our findings of the increased firm risk and cost of capital support the costly external capital channel. The cross-sectional variations in CDS effects demonstrate that both reduced monitoring and the empty creditor problem might be the underlying forces driving the costly external capital channel. Our additional analysis implies that CDS trading is associated with an enhancement in investment efficiency for firms that are prone to overinvestment.     

Childhood adversity and the propensity for entrepreneurship: A quasi-experimental study of the Great Chinese Famine

Studies on the determinants of entrepreneurship emphasize that challenged adults tend to become entrepreneurs. However, research has not addressed the childhood origins surrounding the propensity for entrepreneurship. This article links childhood adversity to the propensity of individuals to become migrant entrepreneurs later in life. We test hypotheses derived from this theory in the context of whether, and when, children who survived the Great Chinese Famine of 1959–1961 became migrant entrepreneurs. Results strongly indicate that those who survived greater hardship during the Famine are more likely to become entrepreneurs, especially when they were younger during the famine years. We also find that being younger at the time of migration increased the likelihood of becoming entrepreneurs in their new locale. Overall, this study casts light on why, how and when childhood adversity shapes the propensity for entrepreneurship.

经济增长目标影响了企业风险承担吗?-基于市场和政府双重视角的考察

中国经济的增长在很大程度上受到中央和地方政府政治和财政激励的影响.地方政府每年都制定明确的经济增长目标以指导地方发展.虽然许多研究从宏观经济的角度研究了该目标的作用,但很少有研究具体考察增长目标在微观经济中的作用方式.文章从地方政府经济增长目标的角度,匹配2009-2015年233个地级以上城市经济增长目标数据和2381家沪深A股上市公司数据,考察了政府经济发展规划如何影响企业风险承担水平.研究发现,地方经济增长目标的提高显著增加了企业风险承担水平,且在更换了企业风险承担和经济增长目标衡量方法以及考虑内生性问题后,结论依然存在.在外部资源的调节效应方面,经济增长目标对能获得高政府补助、融资约束程度低以及能获得高贷款的企业的风险承受水平的提升作用更大.而异质性检验发现,地方经济增长目标对企业风险承担水平的刺激效应主要体现在具有一定规模、国有企业和具有政治关联的企业中;以及主要体现在发展水平较低和市场化程度较低的城市中.这些发现表明,地方经济增长目标对企业风险承担水平的正面影响主要还是地方政府主导资源分配的结果,而并非市场信号机制的结果.     

我国城市住房保障水平评估——基于公租房准入门槛的量化分析

本文通过对全国153个地级及以上城市公租房准入政策和条件进行量化分析,运用主成分分析法构建起公租房准入指数,用以反映城市住房保障水平.以此为基础,本文利用中国家庭金融调查的微观数据,实证检验公租房准入指数对家庭居住公租房的影响.结果 显示,公租房准入指数越高,家庭获得公租房的可能性显著增加,从而验证该指数的合理性.文章发现,尽管在大力倡导新型城镇化的背景下,各地公租房仍然对外市户籍人口存在较高门槛.随着城镇化水平不断提高,人口流动持续增强,中央政府应建立对各城市科学合理的住房保障评估体系,重构地方政府激励机制,提高地方政府住房保障的积极性,同时应加大对外来居民的保障力度.     

中国高端装备制造业自主技术创新效率稳定性及影响因素研究

在全面实施创新驱动发展战略的时代背景下，揭示中国高端装备制造业自主技术创新效率稳定性，测度相关因素的影响强度与方向，对揭示中国高端装备制造业自主技术创新规律，制定其发展策略具有重要指导意义。聚焦中国高端装备制造业自主技术创新效率稳定性及影响因素，采用DEA-Malmquist指数方法和Tobit回归模型进行实证研究，结果表明，中国高端装备制造业自主技术创新效率存在一定波动性，且各细分行业技术创新效率内部稳定性较差，产业自主技术创新效率整体稳定性不高；自主技术创新投入因素和环境影响因素对产业自主技术创新效率的影响具有较高的异质性，其中创新资金投入和人力资源投入对自主技术创新综合效率、纯技术效率及规模效率具有正向影响，而新产品开发投入和企业规模对自主技术创新综合效率、纯技术效率和规模效率的影响具有异质性，政策因素与市场因素分别具有显著和非显著负向影响，外源性创新因素具有显著正向影响，且影响强度较大。在此基础上，提出调整政府对高端装备制造业创新支持模式、加强外源性创新与智力引进等策略建议。     

长江经济带人才集聚水平测度及时空演变研究——基于价值链视角

基于价值链视角，构建涵盖人才资源在区域空间层面集聚生成、地区配置、效能产出3个维度在内的区域人才集聚水平评价指标体系，采用专家咨询AHP-信息熵组合赋权法构建综合评价模型和耦合协调度模型，对2010—2018年长江经济带沿线省市人才集聚水平进行测度与时空演化特征分析。结果表明，就长江经济带整体而言，考察期内地区人才集聚水平总体呈现逐年上升态势，但仍处于低水平状态；沿线省市人才集聚水平差异显著，缩小趋势渐缓，整体呈现局部高水平、全局低效率的不利境况；各省市人才集聚水平关键维度的耦合协调度整体呈显著波动递增态势，但内部耦合协调度存在不平衡发展问题，影响地区人才集聚水平整体提升。为提升长江经济带人才集聚水平，推进沿线地区协调发展，需强化区域人才合作机制，采取差别化精准策略破解沿线地区人才集聚低水平、不协调的短板因素。     

Client Importance and Audit Quality at the Individual Audit Partner,Office, and Firm Levels

We investigate whether audit partner level data provides a more powerful measure than office or firm level measures of client importance. We find that the likelihood of issuing a going-concern opinion (any and first-time) increases, and the absolute value of discretionary accruals decreases, in relation to the proportion of audit fees to the total audit fees received by audit partners from all their clients. We also find that the likelihood of issuing a going-concern opinion (any and first-time) increases, and the absolute value of discretionary accruals decreases, in relation to the proportion of non-audit services fees from a client to total non-audit service fees, and the proportion of total audit and non-audit service fees from a client to total fees from all their clients at the office and firm levels. Our findings provide evidence to regulators, audit clients, and stakeholders that audit partners do not succumb to pressure from economically more important clients as audit quality has a positive association with client importance.     

珠三角工业设计与工业互动比较研究：双重需求拉动与设计驱动增长的区域验证

动态比较珠三角工业发展阶段和设计水平不同的典型区域内，工业用户和最终消费者用户双重需求拉动设计创新以及设计驱动工业增长作用机制的异同，提出克服互动系统短板并因地制宜实施设计驱动转型升级的对策建议。基于SVAR建模的脉冲响应和方差分解分析发现：珠三角工业确实可以通过工业设计创新驱动实现内生性可持续增长，而设计水平的地区差异对设计驱动绩效有调节作用；工业发展质量和结构欠佳，无法有效拉动区域工业设计创新，是珠三角多数地区工业设计有效需求不足的根本原因。区域工业设计与工业互动系统的短板是缺乏内行和挑剔的最终消费者有效需求。最后基于模型稳健性检验，提出因地制宜科学实施设计驱动发展战略的对策建议。
