近墨者黑:上市公司违规行为的“同群效应”

近年来,上市公司违规行为群发,本文利用2000-2016年沪深A股上市公司违规事件样本,从“同群效应”的角度探究违规行为的群体特征和影响因素。研究发现,上市公司违规行为存在显著的地区同群效应(“近墨者黑”),同地区其他上市公司的违规行为显著增加了该地区公司发生违规行为的概率;且信息披露型违规的同群效应更加明显。机制研究表明,企业违规决策的地区同群效应主要源于交流式学习和观察式学习的两种模仿作用机制。异质性分析表明,同一地区内,相同产权性质公司间的同群效应更明显。进一步研究显示,十八大之后违规行为的发生概率显著降低,地区同群效应显著减弱。本文研究揭示了违规行为的地源性特征,也从抑制违规传染视角实证支持了近年来的系列整治活动。     

Over‐investment or risk mitigation? Corporate social responsibility in Asia‐Pacific,Europe, Japan,and the United States

We study the relationship of corporate social responsibility (CSR) and the distribution of stock returns for an international sample. Firms with a high level of CSR generally exhibit superior stock price synchronicity in the markets of Europe, Japan, and the United States. In particular, we identify optimal levels of CSR to minimize idiosyncratic risk for each region. Moreover, CSR has a mitigating effect on crash risk in Europe and the United States. In contrast, firms from the Asia‐Pacific region display CSR over‐investment followed by a higher crash risk. This appears to be a consequence of globalization, which forces firms from Asia‐Pacific to overinvest in CSR to adapt western standards.     

Do specialized board committees impact the transparency of corporate political disclosure? Evidence from S&P 500 companies

This study examines how the specific attributes of one type of voluntary corporate governance mechanism, a specialized political contribution committee, improves the transparency of corporate political disclosure (CPD). The results demonstrate that the existence of a committee that establishes and reviews key political activities and disclosure policies, particularly one composed entirely of outside directors, significantly enhances the transparency of corporate political disclosure, and reveal that an under-studied board committee, the political contribution committee, effectively improves CPD transparency. The results are consistent with agency theory and further support the more generalizable idea that specialized governance mechanisms (e.g., a political contribution committee) and fully independent committees lead to more transparent disclosure. Finally, the results suggest that the existence of a political contribution committee and committee independence are channels to improve CPD transparency. Public-policy makers and regulators seeking to enhance CPD transparency might consider implementing regulations that mandate or recommend these governance mechanisms as best practice.     

How supply chain architecture and product architecture impact firm performance: An empirical examination

In order to enhance performance, manufacturing firms are building various capabilities and utilizing supply chain networks that are geographically dispersed around the globe. This study examines how decisions related to supply chain architecture and product architecture influence organizational competitiveness. Building on the co-specialization perspective, we evaluate the performance implications of product modularity and supply chain agility. While, product modularity constitutes a product configuration related to sourcing and assembling of products, supply chain agility is a supply chain configuration related to velocity (sensing, comprehending, and responding) and visibility (supplier network, internal operations, and external environment). Both the product and supply chain architectural decisions can impact performance, individually and in conjunction with each other. We empirically test the hypothesized relationships using data collected from 103 manufacturing firms. Results show that supply chain agility and product modularity directly enhance responsiveness and enable organizations to reduce cost. Furthermore, supply chain agility partially mediates the relationship between product modularity and both responsiveness and cost reduction. We elaborate on the key contributions of this study for both research and practice, discuss limitations, and also offer various avenues for further research.     

Corporate social responsibility and Eurozone corporate bonds: The moderating role of country sustainability

In this paper, we empirically examine whether superior performance in corporate social responsibility (CSR) results in lower credit risk, measured by credit ratings and zero-volatility spreads (z-spreads). We are especially interested in how the environmental, social, and governance (ESG) related performance of the corresponding countries moderates this relationship. We find only weak evidence that superior corporate social performance (CSP) results in systematically reduced credit risk. However, we do find strong support for our hypothesis that a country’s ESG performance moderates the CSP–credit risk relationship. Superior CSP is regarded as risk-reducing and rewarded with better ratings and lower z-spreads only if it is recognized by the environment. In addition, we find a reduction of corporate bonds’ z-spreads by approx. 9.64 basis points if the CSP of a company mirrors the ESG performance of the country it is located in.

Institutional duality and political strategies of foreign-invested firms in an emerging economy

This study investigates how the complex institutional environment surrounding foreign-invested firms (FIEs) affects their corporate political strategies (CPS) in China. Analyses of data on 442 FIEs operating in China show that the relative potency of dual institutional pressure from FIEs’ home and host countries shapes their strategic choices. Institutional factors at the country, region, and firm levels not only affect firms’ adoption of multiple firm-based tactics but also shape their collective-oriented associational activities. Moreover, participation in both foreign and domestic business associations enhances an FIE's adoption of firm-based political tactics, but joining domestic business associations has a stronger effect.     

Extent of corporate governance disclosure by banks and finance companies listed on Nepal Stock Exchange

Corporate governance disclosure has seen renewed interest by researchers, policy makers, and regulating bodies internationally, but has remained only an emerging construct in Nepal. The primary purpose of this study was to assess the extent of mandatory corporate governance disclosure in Nepal. The secondary purpose was to examine the associations between the extent of disclosures and five firm-specific characteristics. The third purpose was to assess the significant determinants to explain variations of disclosures. The study's sampling frame consisted of 125 banking and finance companies listed on Nepal Stock Exchange. A sample size of 59 companies was randomly selected. On average, companies disclosed 91% of items in the mandatory category, 48% in the voluntary category, and 74% in total. A significant positive correlation existed between governance disclosures and firm characteristics of size, leverage, and foreign ownership. There was no significant relation between governance disclosure and listing age or profitability. With regards to determinants, bank size was a significant predictor of governance disclosure. Three regression models for total disclosures (DScore), mandatory disclosures [DScore (M)], and voluntary disclosures [DScore (V)] with three predictors of size, leverage, and foreign ownership were significant and explained 47%, 24%, and 54% variations respectively in total, mandatory, and voluntary corporate governance disclosures in Nepal. This research provides guidelines to policy makers and standard setters for developing future regulations and accounting policies.     

The impact of equity ownership groups on investment: Evidence from Ukraine

We empirically investigate the impact of different ownership groups on companies’ investment in Ukraine with a novel dynamic investment model where investment is based on present and historical levels of profitability (market-to-book value of equity) and lagged investment. Groups include state, insider, non-domestic, financial and financial and industrial group (FIG) ownership. Contrary to the literature, we find that the past level of profitability significantly affects investment; the majority presence of and increases in state ownership have a negative impact on firms’ investment, as is the case for non-domestic and financial companies’ ownership. Insider and FIG ownership have no impact on investment. We explain the results by the extent of liquidity concerns (hard and soft budget constraints), measured by cash flow interacted with a dummy variable of majority ownership of the respective group, and the extent of asset stripping for the corresponding ownership group and relate them to over- and under-investment, and to the free cash flow or cash constraint hypothesis.     

Engagement partner specialization and corporate disclosure transparency

This paper explores the association of audit partners' industry specialization with corporate disclosure transparency and the latter's informativeness. The distinctive institutional designs of partner signature requirement and Information Disclosure and Transparency Ranking System (IDTRS) adopted in Taiwan allow us to empirically address the issue. We posit and find that the rankings from the IDTRS are higher for firms audited by industry specialist engagement partners than for firms audited by non-specialist engagement partners. Additionally, the results show that the probability of informed trade (PIN) proxy for information asymmetry is negatively associated with the rankings for clients of industry specialist engagement partners, but not for clients of industry non-specialist engagement partners. The results are robust with respect to alternative estimation method and alternative measures of industry specialization. Overall, the evidence suggests that industry specialist engagement partners enhance the credibility of corporate disclosure transparency, through which information asymmetry is further declined. The evidence provides policy implications to the partner signature requirement adopted in Taiwan and China.
