The effects of legal regime on the patterns of stock returns surrounding ADR earnings announcements

This study examines the effects of legal regime on the patterns of stock returns surrounding the earnings announcements of American Depositary Receipt (ADR) programs. My results indicate that the properties of accounting earnings associated with the local legal regime of an ADR program spill over to U.S. GAAP reconciled earnings. In particular, I find that the market reacts significantly to the earnings announcements of the ADR programs from common law countries whose accounting earnings are known to be more conservative and timely, but not to those of the ADR programs from code law countries where the earnings are known to be less conservative and timely.     

The Impact of Universal Stock Futures on Feedback Trading and Volatility Dynamics

Abstract:  This paper investigates the impact of the introduction of Universal Stock Futures (USFs) on underlying market dynamics (volatility and the level of feedback trading). Analysis of USFs provides a number of advantages compared to investigation of index futures, leading to reliable and wider ranging insights into the impact of derivatives. Specifically: (i) any impact of derivatives is more likely to be evident in the behaviour of individual stocks; (ii) with USFs it is possible to directly trade the underlying; (iii) USFs have multiple introduction dates within a given market; (iv) differential country/industry effects can be identified; and (v) the endogeneity issue can be addressed using control stocks. Findings suggest limited feedback trading in USF stocks, but listing has reduced this further. While news has less impact and persistence and asymmetry effects are more evident post-futures, control stock results suggest these changes are not futures induced. Differences are evident across industries. The need for analysis of an appropriate (industry based) control sample is highlighted if reliable policy conclusions are to be reached.     

Do cross-listers bond to U.S. markets? An examination of earnings quality around SOX

Sarbanes–Oxley [SOX, hereafter] was expected to improve the overall quality of financial reporting. A large amount of research has documented the influence of SOX on companies' reporting behaviors and how those behaviors have impacted the capital market as a whole (Cohen et al., 2008; Engel et al., 2007; Lobo & Zhou, 2006). While the assumption is that the far-reaching regulation impacts all U.S.-listed companies, this paper considers whether SOX has had a differential impact on the earnings quality of foreign filers that cross-list on U.S. exchanges. Despite some minor exceptions, these foreign companies are expected to meet the same reporting standards as domestic U.S. companies. Using a sample of cross-listers around the enactment of SOX, the results suggest that cross-listed companies do not strictly comply with SOX. At the same time, a size-matched sample of domestic U.S. companies shows significant improvement across the same set of earnings quality measures. This differential impact raises concerns about the ability of domestic regulations to impose compliance on foreign filers. While some may believe that cross-listed companies are bonding themselves to U.S. regulations and reporting quality, the evidence in this paper suggests that foreign companies are more interested in the reputational gains associated with a listing in the U.S.     

黑龙江省民营企业境外上市状况分析及对策建议

近年来,黑龙江省的一些民营企业通过首发上市和买壳上市的方式,在境外上市融资方面进行了有益的尝试,取得很多宝贵的经验,但同时也遇到了对培育民营企业上市资源和推介企业上市工作重视不够、相关部门职责不清,优质上市资源匮乏等问题。应加强对民营企业境外上市工作的宏观管理,积极培育优质上市公司的后备资源,制定对拟上市公司的政策扶持措施,支持行业龙头民营企业的重组发展和做大做强。     

境外上市在我国企业国际化进程中的作用

以在香港联交所上市的境内企业为样本,从收入的地区分布角度考察境外上市在我国企业国际化进程中的作用。研究结果发现:境外上市企业比仅在境内上市的企业更为依赖国际市场。但对境外上市企业境外上市前后境外收入占比的对比分析表明,境外上市并没有对我国企业拓展国际市场业务起到显著的推动作用。     

研发投资强度与上市年龄——基于企业生命周期视角

基于中国A股上市公司的研发数据,在企业生命周期视角下,采用混合数据OLS回归检验研发投资强度与上市年龄之间的非线性关系特征。全样本回归结果显示,上市年龄对研发投资强度有显著的负向影响。进一步,年轻企业的研发投资强度呈现“倒U型”特征,出现“创新衰退”效应,新兴行业更加明显;中老龄（老化）企业的研发投资强度呈现“正U型”特征,出现“转型”效应,传统行业和中小型企业的“转型”效应更为显著。
