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.  相似文献

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.  相似文献

2014年,世界经济尤其是欧盟们经济持续低迷、我国国内经济发展增速放缓已处于"新常态"发展。大陆桥国际运输较往年呈现出一派欣欣向荣的景象,虽然国际过境运输量有所下滑,但整体情况尤其是中欧班列发展迅猛。这主要得益于我国以及亚欧国家对丝绸之路经济带建设的重视和积极参与。2014年,世界经济尤其是欧盟们经济持续低迷、我国国内经济发展增速放缓已处于"新常态"发展。因此,2014年我国交通运输经济运行虽然总体发展平稳,但增速趋稳。港口生产有所放  相似文献

Overuse of nitrogen fertilizer represents a considerable environmental problem globally, but especially in China. Recently, a recent approach on an experimental scale based on the diffusion of the so-called Three-Control Technology (TCT) successfully alleviated the overuse of nitrogen fertilizer in southern China villages in the Guangdong Province, serving as a reference point for other rice-producing countries tackling similar challenges. Here, we assessed the correlation between rice yields and reduction in the use of nitrogen fertilizer following the introduction of TCT. Our study was based on the collection of primary data from 248 households randomly selected from four rice-growing areas of Guangdong Province, China. Our results show that TCT significantly improved the efficiency in the use of nitrogen. Crucially, participating farmers, including both full adopters and partial adopters, were found to fundamentally change their application practices of nitrogen fertilizer, resulting in major improvements in the local soil and water systems.  相似文献

Credit default swaps (CDS) are similar to out-of-the-money put options in that both offer a low cost and effective protection against downside risk. This study investigates whether put option-implied volatility is an important determinant of CDS spreads. Using a large sample of firms with both CDS and options data, we find that individual firms’ put option-implied volatility dominates historical volatility in explaining the time-series variation in CDS spreads. To understand this result, we show that implied volatility is a more efficient forecast for future realized volatility than historical volatility. More importantly, the volatility risk premium embedded in option prices covaries with the CDS spread. These findings complement existing empirical evidence based on market-level data.  相似文献
