农业供应链金融视角的农户信贷约束缓解效应研究——来自湖南农户的经验证据

采用多元多值非条件Logistic回归方法,依据湖南省50个县(市、区)1059个农户样本数据,考察农业供应链金融对农户信贷约束的缓解效应。结果显示：农户参与农业供应链金融能够缓解供给型与需求型农户信贷约束,缓解效应随着农户收入增长、金融发展和农户社会资本提升而减弱,机制检验证实了信息对称、信用等级、交易成本、抵押替代在缓解农户信贷约束过程中起到部分中介效应。鉴于此,需要在创新模式、优化环境以及加强引导上着力发展农业供应链金融。     

Short sellers and insider trading profitability: A natural experiment

We examine the impact of short sellers on insider trading profitability using a natural experiment of a pilot program which relaxed short-selling constraints for randomly selected pilot stocks. We find that pilot firms experienced a significant decrease in insider trading profitability during the pilot program. The results are more pronounced for the pilot firms with poor information quality, and for the pilot firms without corporate restrictions on insider trading. Our evidence suggests that short sellers serve an important market disciplinary role by reducing insider trading profitability.     

Terrorism activities and long-term annual management forecasts

We study the effects of terrorist attacks on firms’ long-term annual management earnings forecasts bias. We find that the managers of firms located closer to the epicenters of attacks are more likely to issue optimistic long-term annual earnings forecasts relative to the managers of a control group of unaffected firms. The exposure effect is stronger for more severe terrorist events, and firms with more uncertain fundamentals and less geographic diversification. In addition, we document that managers’ forecast optimism intensifies for firms with stronger negative stock market reaction to the terrorist event, for CEOs with higher ability and for companies that are more likely to issue equity or engage in acquisitions following the terrorist event. Overall, our results are consistent with the idea that long-term annual earnings forecasts are used by managers to counterbalance the short-term pessimistic response to terrorist attacks.     

Media attention and regulatory efficiency of corporate violations: Evidence from China

We examine the influence of media attention on the regulatory efficiency of corporate violations in a restrictive media environment. Using a hand-collected sample of corporate violations in China during 1998–2018, we find that fraudulent firms accompanied by more negative media attention are associated with a higher hazard rate of the violation being investigated and enforced. The effect is not diminished by the political connections of the fraudulent firms and is robust after controlling for potential confounding factors. Our findings suggest that by influencing regulatory efficiency, the media serve as an effective governance mechanism even in markets with strict media control.     

Unfolding institutional plurality in hybrid organizations through practices: The case of a cooperative bank

This paper provides a theoretically informed analysis of how institutional pluralism unfolds in hybrid organizations through practices. Building on Quattrone's (2015) procedural model, the paper studies institutional plurality in the case of an Italian cooperative bank that has experienced enduring success. By reversing the usual approach to logic, defined as a stable set of beliefs, this paper shows that this hybrid organization uses a recursive system of practices in search of social order. This hybrid organization interrogates its organizational imperatives and defines adequate ways to achieve them. This paper then observes that this system of practices is permeable to external pressures, i.e., inspections by the central bank, a reform of cooperative banks, political pressure for mergers and acquisitions, and Italy's sovereign debt crisis. While such an organization appears to be ongoingly accountable to its multiple stakeholders, external pressures undermine its community accountability system and push this hybrid organization towards compliance accountability. Based on our findings, this paper develops a process model for hybrid organizations to navigate institutional plurality and to explain the potential limitations of the accountability system.     

人力资本对非农就业收入的影响——基于村庄内外的视角

利用山西省2004年3 506名农村居民的抽样调查数据,比较分析了人力资本对劳动力村内、村外非农就业收入的影响。在进行OLS估计,考虑到可能出现的选择性偏误,使用Heckman二阶段模型进行纠正后发现,无论是在村内还是在村外,受教育年数对非农就业收入均有显著的正向影响;受过职教培训与劳动力村内非农就业收入具有显著的负向关系,但其对村外非农就业收入的促进作用却十分明显;拥有技术职称在村内取得了显著的收入回报;健康对于村内非农就业收入的影响并不十分明显,但在村外,健康成为重要的影响变量。     

公共行政的范式转换及其政府信任问题

政府信任是政府和公众之间基于公共利益的博弈互动关系．符合公共利益的行政价值理念将为政府提供持久的、合法的信任源泉。从官僚制到新公共管理，由于片面注重管理主义工具价值，而忽视公共利益和民主价值，不可避免地面临着政府信任的困境。民主行政作为新公共行政的学术识别系统。坚持和发展公共利益价值取向，实现价值理性和工具理性的统一，符合人类理性与社会公共利益均衡健康发展的内在需要。必然会全新构建和强化公众与政府的互信合作关系。     

高管团队兼职行为与企业业绩关系研究

本文以沪深106家高科技上市公司为研究样本,实证考察了企业高管团队成员的蓉职行为与企业绩效之间的相关性.研究发现高管成员的兼职行为与企业业绩之间存在显著的相关关系.高管兼职企业的规模越大、赢利情况越好,越有利于提高本企业的业绩;高管在企业集团外部兼职的企业数量越多越有利于提高本企业的业绩;高管在企业集团内部兼职企业的数量与业绩关系不显著.     

粮食主产区农民收入影响因素的计量分析

粮食主产区农户家庭收入与农户家庭劳动力受教育水平、粮食单产、优质粮食品种播种面积、农户家庭投资能力呈正相关,与农户家庭农业劳动时间呈负相关.农户家庭社区特征和家庭特征对农户家庭收入发挥着重要的影响作用.粮食主产区应扩大优质粮食品种种植面积,加快剩余劳动力转移,提升农户家庭投资能力,从而提高粮食主产区农民收入.     

公募基金内部羊群行为研究

以往对公募基金羊群行为的研究聚焦于宏观层面不同基金公司所持股票组合的相似性,而该研究则从微观视角研究了羊群行为:(1)单个公募基金公司所管理的多个基金相互模仿投资策略所呈现的羊群行为;(2)基金经理的交易行为所呈现的羊群行为。使用LSV模型测量2010—2019年多个公募基金公司内部的羊群行为,发现同个公募基金公司所管理的多个不同基金存在相互模仿投资策略的羊群行为,程度高于宏观层面不同公募基金之间相互模仿的羊群行为。此外,还发现基金经理的买入卖出交易行为存在羊群效应。研究从新的视角检验了微观层面的羊群行为,为基金公司加强内部管理、避免基金经理跟风投资造成风险聚集提供参考。
