Inter-industry labor reallocation and task distance

This paper investigates factors preventing inter-industry labor reallocation by estimating the determinants of inter-industry worker flow and earnings change after a job change. We find that the difference in required tasks is an important reason for earnings reduction after an inter-industry job change, and thus, workers may hesitate to move to industries requiring a different set of tasks for fear of losing the wage premium acquired by task-specific human capital. In addition, more workers switch to industries with which their previous industry had larger transactions, although it affects earnings changes only marginally. On the other hand, industry performance does not affect labor inflow or wage changes significantly for inter-industry job changes. Young men, less educated women, and those quitting previous jobs for family or health reasons are more likely to move to industries requiring a different set of tasks, and young individuals who lost their jobs involuntarily are less likely to do so. Individuals more likely to move are not necessarily those whose earnings loss associated with the move is small: earning losses associated with task distance are relatively small among younger and less educated workers and are uncorrelated with the reasons for quitting the previous job.     

社会资本与超额在职消费：激浊扬清还是推波助澜

作为企业治理的重要问题之一，代理成本诱发超额在职消费引起各界广泛关注。文章以2007-2019年A股上市公司为初始样本，考察我国各省社会资本水平差异对超额在职消费影响。研究表明，社会资本显著提高超额在职消费，起到推波助澜的负面效用；进一步研究表明，公司治理水平维度上通过提高机构投资持股比例、短期债务融资比例及扩大独立董事比例和监事会规模均能抑制社会资本加剧超额在职消费的负面效用，公司治理环境维度上通过强化企业内部治理环境、加快市场化进程亦能削弱社会资本对超额在职消费的“推波助澜”。以上结论为社会资本利弊之争提供有益补充，亦凸显非正式制度与正式制度的治理替代效应，同时为企业完善内部治理水平及政府优化制度环境与规则治理以抑制社会资本负面效用提供一定借鉴。     

基于K-S检验与距离相关分析的网络借贷信用评价指标体系构建

网络借贷作为一种新型互联网金融模式,提升了金融资源使用效率,缓解了小企业融资难的困局。构建合理的网络借贷信用评价指标体系,从而对网络借贷的潜在风险及时甄别与预防,对互联网金融健康持续发展意义重大。本文根据K-S检验与距离相关分析相结合,筛选对借款客户违约状态甄别能力强的指标,建立了网络借贷信用评价指标体系,通过P2P网络借贷(peer to peer lending,个人对个人借贷)平台LendingClub交易数据进行实证研究,结果表明:不仅借款金额、借款利率等借款标的特征对借贷者违约具有显著相关性,借款者年龄等个人特征、借款者年收入等财务特征以及借款者违约次数等信用特征均对借贷者违约风险产生显著影响。投资者在出借资金时,往往青睐于已婚、年龄适中、具有一定工作经历、历史违约次数较少的借款人。因此,风险监管部门应构建网络借贷违约风险评估模型,对P2P平台进行风险监测,同时建立关键信息共享机制,融合多源数据,明确审查范围,实现P2P网络借贷行业健康有序发展。     

敦煌种业财务绩效评价研究

选择以农业上市公司敦煌种业为研究对象,以企业2014—2019年的报表数据为基础,采用功效系数法并以国务院国资委所编写的《企业绩效评价标准值》中国有企业绩效评价体系作为参考,构建对农业企业的财务指标评价体系,对敦煌种业2014-2019年企业财务指标的表现进行纵向分析,选择同行业中营业收入水平较高的北大荒进行横向对比,通过对比发现敦煌种业的问题主要体现在盈利能力和资产质量方面,对此提出了改进措施及建议。     

Information transmission between large shareholders and stock volatility

Does information transmission between large shareholders exacerbate stock volatility or reduce stock volatility? In this study, based on the common shareholding data in the Chinese stock market from 2007 to 2017, we establish the shareholder’s coshareholding network, and use the weighted network clustering coefficient to measure the information transmission speed. Moreover, we investigate the impact of information transmission speed on stock volatility. The empirical results show that a nonlinear U-shaped relationship exists between information transmission speed and stock volatility. The findings are robust to the inclusion of other determinants of stock volatility identified in the literature. Finally, we verify the existence of private information interaction in the coshareholding network.     

金融素养、家庭财富与家庭创业决策

本文利用2015年中国家庭金融调查(CHFS)数据,分析了金融素养、家庭财富与家庭创业决策三者之间的关系。整体上,金融素养的提高显著增加了家庭参与创业的可能性,但家庭参与创业面临着"财富约束效应";而金融素养对家庭财富具有替代作用,提高金融素养有效缓解了家庭的"财富约束效应",促进家庭参与创业。同时,研究发现家庭财富对家庭创业决策的影响并不存在明显的城乡差异,但金融素养更能缓解农村家庭创业所面临的"财富约束效应"。另外,提高金融素养能有效缓解家庭的信贷约束,增加其风险偏好,间接地促进创业。     

Pricing the hedging factor in the cross-section of stock returns

We investigate the role of investors’ net hedging strategy (factor) in predicting stock returns and pricing the cross-section of individual stocks and equity portfolios. We estimate stock exposure to changes in the hedging factor and show that the hedging premium is driven by outperformance of stocks with large positive net hedging betas, which explains their higher average returns. We find the positive hedging premium indicates risk-averse investors demand extra compensation to hold stocks with higher equity risk premiums, and they are themselves willing to pay higher prices for stocks with positive hedging betas.     

Moral hazard,debt overhang and capital structure

This paper investigates the impact of managerial moral hazard on the debt overhang of a firm by constructing a contingent claims model in which the manager faces costly effort. Using a calibrated capital structure model, we show that the costs of debt overhang become more serious in the presence of managerial moral hazard. Such costs even account for more than half of the total agency costs at a high level of cash flow. Moreover, in contrast to the results of Hackbarth and Mauer (2012), our model predicts a U-shaped relationship between the leverage ratio and investment opportunities of a firm, which is caused by managers’ moral hazard. Finally, by considering this moral hazard, we also show the coexistence of low leverage ratios and high credit spreads, which explains the phenomenon of “low debt levels and high credit spreads” observed in practice.     

Relationship between foreign capital flows,domestic investment and savings in the SADC region

The importance of foreign capital in the domestic economy cannot be underestimated as it bridges the gap between domestic capital demand and supply. Given this background the paper studies the relationship between the different types of foreign capital flows in the Southern Africa Development Region (SADC) region – foreign direct investment (FDI), remittances, cross border bank flows (CBF), overseas development assistance (ODA) – and domestic savings and investment, employing the panel cointegration test and the dynamic ordinary least squares method (DOLS). The empirical results reveal that there is a strong positive relationship between domestic investment and domestic savings, FDI and remittances. These findings indicate that FDI remittances help in overcoming the limits on the domestic capital formation in the SADC region through permitting a rate of investment which is in excess of that which can be generated by domestic savings. Important policy implications on attracting foreign capital flows are discussed in the paper.
