The capital market spillover effect of product market advertising: Evidence from stock price synchronicity

We analyze whether product market advertising has a spillover effect on stock price synchronicity by transmitting firm-specific information to the capital market and attracting more investor attention. Using a sample of Chinese listed firms from 2009 to 2017, we find that firms with greater advertising expenditures have lower stock price synchronicity. The results are robust after we address endogeneity concerns. In accord with our hypothesis that product market advertising increases the amount of firm-level information capitalized into stock prices through the information channel, we find that the impact of advertising on synchronicity is more pronounced for firms with a higher degree of information asymmetry and firms in the consumer-product industry. Further tests show that product market advertising enhances the ability of current period returns to reflect future earnings, and thus rules out that the negative relationship between advertising and synchronicity is driven by noise trading. Our results imply that product market advertising plays an informative role and improves information efficiency in a capital market.     

塔里木油田哈得区块标准井及标准井标准工艺流程的构建

为缩短钻井周期、节约钻井成本,塔北项目部率先提出了以标准井及标准工艺流程为经度,以标准化设计、标准化安全管理、标准化工期及费用、标准化质量控制及考核机制为纬度的"五标"管理理念,而标准井及标准工艺流程为构建"五标"管理理念的关键。根据对哈得区块已完钻的直井、水平井、侧钻井、定向井的统计分析,并结合实际生产开发情况,确定了以直井和水平井作为哈得区块标准井的井型;根据标准井产层的各项地层参数,确定了相应标准井的钻头尺寸组合、钻进深度、套管规格、套管下深、泥浆体系、测井等参数,从而构建了哈得区块直井和水平井2种井型的标准井;同时依据各标准井构建了相应标准井的标准工艺流程。通过塔北项目部的生产实践表明,标准井及标准井的标准工艺流程的构建大大有助于提高油田的经济效益和管理效率。     

Immigrants’ net direct fiscal contribution: How does it change over their lifetime?

Life-cycle direct public fiscal contributions and transfers are studied using longitudinal income tax data from 1982 to 2016 and administrative files for immigrants landed in Canada from 1980 to 2016. Relative to a comparison group comprising the Canadian-born and immigrants landed before 1980, immigrants since 1980 have a lower average net direct fiscal contribution (NDFC) during their working years due to their lower taxes and social security contributions but a higher average NDFC after 65 years of age because of reduced public pension eligibility and entitlement. Immigrants who landed at younger than 19 years old have much higher direct fiscal contributions than other age-at-arrival groups and reach their peak of contributions around 10 years earlier in life than other age-at-arrival groups. Immigrants whose age at arrival is above 65 have a less negative average NDFC than other age-at-arrival groups over the above-65 life cycle. These life-cycle age𠄁at-arrival trajectories are stable for immigrants in different landing cohorts. We apply the life-cycle estimates to project the present discounted value of lifetime NDFCs for immigrants who landed in 2016. For each landing age group, refugees and family class immigrants have negative or zero average present values of life-cycle NDFCs, much below that of economic immigrants.

智慧专业化视角下区域资源集聚与区域创新驱动发展

传统发展动力逐渐式微，创新驱动成为区域经济发展的新引擎。走创新驱动发展道路，需要新的经济理论解释、构建并指导各区域经济增长方式和发展模式转型。智慧专业化是一种新兴经济理论，能够较好解释区域创新驱动发展的内在动力。智慧专业化有效支撑区域资源集聚与区域创新驱动发展相关性研究，从资源内存性和外向性、资源技术和经济属性以及资源支持程度3个方面，论述区域创新驱动发展的动力来源与动力持续性，进而解释区域创新驱动发展资源集聚对区域创新驱动发展绩效的影响。     

国企民营化与企业创新效率：促进还是抑制?

文章基于混合所有制改革的背景，从创新效率的视角考察了微观创新主体民营化前后创新行为的变化。研究发现，民营化抑制了企业的创新效率，企业的专利数量显著减少，这种影响在缺乏原国有大股东制衡、无系族的上市公司以及外部产权保护较弱的地区更加显著，而且相对于创业型企业，民营化企业的创新效率更低。进一步研究发现，民营化抑制企业创新效率的一个重要途径是关联交易显著增加、投资显著减少，民营化后非国有大股东更多地表现出掏空动机，减少了创新活动，降低了创新效率。文章的研究结论为理解民营化企业的效率提供了新视角，有助于我们正确认识和理解新兴转轨经济体的民营化行为，而且对于监管层如何推进混合所有制改革具有重要的政策启示。     

Industry competition in China: an external governance mechanism or an external incentive

We focus on the impact of industry competition on earnings management in listed companies in China. Empirical analysis reveals the following: (1) When competition within an industry is relatively low, it lowers the extent of earnings management; (2) when competition is relatively high, earnings management is promoted.; (3) within an industry, the more intense the competition, the more companies manipulate earnings when in an inferior competitive position; and (4) state‐owned enterprises that are at a competitive disadvantage within an industry rely more on real earnings management strategies, whereas these effects are insignificant in private firms.     

The Effect of Cross‐Border Mergers and Acquisitions on Earnings Quality: Evidence from China

Despite the fruitful research on the motives and outcomes of cross‐border mergers and acquisitions (M&As) of Chinese multinational corporations (MNCs), there has been scant research on the impact of cross‐border M&As on corporate governance. In this article, we fill the research gap by exploring whether cross‐border M&As may lead to an improvement in corporate governance of Chinese acquirers. In particular, we examine the impact of cross‐border M&As on earnings quality of Chinese MNCs. We find that the acquisition of a target firm from a developed country leads to a significant improvement on the acquirer's earnings quality. In comparison, the acquisition of a target from an emerging market does not have such an impact. Our results are robust to various corporate governance measures, alternative econometric methods, and controls of relevant firm characteristics and macroeconomic variables. Finally, we show that the effect of cross‐border M&As on earnings quality is more pronounced in non‐state‐owned enterprises (non‐SOEs) that have conducted large M&A deals. Our article offers new insight to the international business literature on latecomer perspective and liability of foreignness. © 2016 Wiley Periodicals, Inc.     

房地产抵押品价值变动的实体经济效应

在我国较密集的房地产调控背景之下,定量测算房地产抵押品价值变动对实体经济的影响幅度具有重要意义.文章采用前沿方法深入考察了房地产抵押品价值变动对公司投融资决策的影响,并在此基础上对房价调控政策对社会总投资的潜在影响进行了估算.研究发现:(1)我国存在显著的抵押品效应,公司房地产抵押品价值每上升1元,资本支出随之增加约5.7分;无论是控制公司固定效应,还是使用替代指标或子样本分析,抵押品效应均稳健成立.(2)宏观层面上,房地产抵押品价值1％的上升将引起总投资增加约466.3亿元.(3)对资金来源的探究显示,抵押品升值提高了公司的贷款获得,尤其是短期贷款的获得.(4)抵押品效应与公司的融资约束正相关,但与所在地区金融市场化水平无明显关系.基于研究结论,建议政府在进行调控时不宜对房价过度打压,而应引导房价保持与居民消费价格相当的增长速度,减少房价过度波动,维持房地产市场长期平稳健康发展.
