Which Socio-Economic Indicators Influence Collective Morality? Big Data Analysis on Online Chinese Social Media

The relationship between Socio-economic factors and morality remains controversial. Previous research has found that wealth makes people unethical, while other research suggests that poverty is a good predictor of unethical behavior. The relationship between other social factors is also ambiguous. In the current study, the relationship between socio-economic indicators reported by the National Bureau of Statistics of the People’s Republic of China and moral motivation revealed from online social networking, Sina Weibo was constructed. Using data from the whole year of 2013 Sina Weibo microblogs, we found that the poor and rich areas were more willing to behave immorally, and the relation between GDP and collective moral motivation was curved. Also, normal people were less ethical when prices increased than when incomes decreased. Ecological construction and the value added by industries which used more farmers and off-farm workers were both correlated with morality. We also found a dark side to science and technological innovation, which harmed collective morality when areas grew richer. But all the results we found were correlational, more casual lab experiments were needed in future research.     

Sell‐Side School Ties

We study the impact of social networks on agents’ ability to gather superior information about firms. Exploiting novel data on the educational background of sell‐side analysts and senior corporate officers, we find that analysts outperform by up to 6.60% per year on their stock recommendations when they have an educational link to the company. Pre‐Reg FD, this school‐tie return premium is 9.36% per year, while post‐Reg FD it is nearly zero. In contrast, in an environment that did not change selective disclosure regulation (the U.K.), the school‐tie premium is large and significant over the entire sample period.     

Management earnings forecasts,insider trading,and information asymmetry

We investigate whether senior officers use accrual-based earnings management to meet voluntary earnings disclosure (i.e., management earnings forecasts) before selling or buying their own shares when they have private information. This study is the first to use the differences in timing of trades by senior officers and other insiders (e.g., directors or large shareholders) to infer information asymmetry. We hypothesize that the timing of senior officers' trades with no other insiders' trades at the same time indicates opportunistic trades and asymmetric information between senior officers and other insiders. Our results show that senior officers' exclusive sales are negatively associated with future returns, indicating that they tend to use insider information. Moreover, senior officers are more likely to meet their earnings forecasts when they plan to sell stocks.     

Social networks in the global banking sector

We show that banks with shared social connections partner more often in the global syndicated loan market and that central banks in the network play dominant roles in various interbank transactions, indicating that social connections facilitate business connections. However, more centralized banks in the network also contribute significantly to the global systemic risk. Moreover, we find the soft information generated by social networks is particularly valuable when potential partners operate under different accounting and regulatory standards. Finally, we show that the recent banking crisis significantly limited the positive soft information effects of social networks in the global banking system.     

External social networks and earnings management

Using a sample of U.S. listed firms for the 2000–2017 period, we examine how external social networks of top executives and directors affect earnings management in their firms. We find that well-connected firms are more aggressive in managing earnings through both accruals and real activities and that the results are robust after controlling for internal executive social ties. Using a difference-in-differences approach, we find that earnings management decreases after a socially connected executive or director dies. Additional analysis shows that connections forged by past professional working experiences have a greater impact on earnings management than connections forged by education and other social activities. Moreover, CFO social networks have a greater influence on earnings management than CEO social networks. Finally, we explore the underlying mechanisms, finding that 1) firms that are socially connected to each other show more similarities in their earnings management than firms that do not share a connection, and 2) more connected firms are less likely to incur accounting restatements. Collectively, our findings indicate that the external social networks of top executives and directors are important determinants of both their accrual- and real activity-based earnings management.

高管团队内部网络与并购绩效

近年来,高管外部社会网络特征对企业决策的影响受到学术界的广泛关注。与以往研究侧重点不同,本文探究高管团队内部网络结构对企业决策是否产生重大影响,并构建了上市公司高管团队内部网络结构指标。基于社会网络和信息不对称等相关理论,本文实证检验了高管团队内部网络对企业并购决策绩效的影响。结果显示,高管团队内部网络结构密度越高,高管成员之间的沟通越有效,公司并购绩效越好。进一步地分析发现,当并购的复杂度和风险较高、企业所在地区制度环境较差以及高管任职时间较短时,高管团队网络密度对于并购绩效的影响更为明显。最后,本文还发现高管团队内部网络密度高的企业并购后,公司的会计业绩和市场业绩也优于其他公司。     

CEOs' hometown connections and access to trade credit: Evidence from China

In this study, we investigate how informal institutions, namely, chief executive officers' hometown connections with suppliers, impact firms' access to trade credit. Using unique data manually collected from China, we find that hometown connections significantly increase access to trade credit. The hometown effect is more pronounced for non-state-owned firms, firms in provinces with poorly developed financial institutions, and firms whose chief executive officers come from hometowns with a strong merchant guild culture or hold an important position in the hometown's chamber of commerce. We suggest two plausible channels for the hometown effect: information and social trust. Overall, this study contributes to the literature by documenting how hometown connections help firms to obtain external financing in emerging markets.     

Do CEOs Matter? Evidence from Hospitalization Events

Using variation in firms’ exposure to their CEOs resulting from hospitalization, we estimate the effect of chief executive officers (CEOs) on firm policies, holding firm-CEO matches constant. We document three main findings. First, CEOs have a significant effect on profitability and investment. Second, CEO effects are larger for younger CEOs, in growing and family-controlled firms, and in human-capital-intensive industries. Third, CEOs are unique: the hospitalization of other senior executives does not have similar effects on the performance. Overall, our findings demonstrate that CEOs are a key driver of firm performance, which suggests that CEO contingency plans are valuable.     

Helping hands or grabbing hands? An analysis of political connections and firm value

We construct a unique political connection index to capture variations in the strength of firm political relations in China. The index incorporates various channels through which a firm's executives, chairperson, directors, and other senior officers are politically connected with government officials and bureaucrats. Overall, there is a negative relation between our index and firm value for the full sample, but such negative relation mainly exists for state-owned enterprises (SOEs) and it becomes positive for non-SOEs. Furthermore, close examination shows an inverted U-shaped relation between political connections and firm value for the full sample in general and for non-SOEs in particular: Firm value increases initially at a lower level of connections and then begins to decrease at a higher level. The findings are consistent with the different business objectives and motivations of SOEs and non-SOEs in seeking political connections. Finally, our findings are robust after controlling for potential endogeneity and using an alternative headcount index construction method.     

Divisional Managers and Internal Capital Markets

Using hand‐collected data on divisional managers at S&P 500 firms, we study their role in internal capital budgeting. Divisional managers with social connections to the CEO receive more capital. Connections to the CEO outweigh measures of managers' formal influence, such as seniority and board membership, and affect both managerial appointments and capital allocations. The effect of connections on investment efficiency depends on the tradeoff between agency and information asymmetry. Under weak governance, connections reduce investment efficiency and firm value via favoritism. Under high information asymmetry, connections increase investment efficiency and firm value via information transfer.     

Employment mobility and pay for sector performance

We argue that executives' employment mobility significantly affects their pay for sector performance. In particular, as executives' outside employment options increase with social connections we hypothesize that better-connected executives receive greater pay for sector performance. Supportive of our hypothesis, we find that pay for sector performance is more pronounced when executives are better connected, both within and across industries. Further, intra-industry connections have a stronger effect when enforceability of non-compete agreements is weaker. While the prior literature finds that social networks impact the level of CEO pay through an information channel, our findings suggest that social networks also impact pay for sector performance through an outside employment options channel.     

The Information Technology Payoff: Implications For Investment Appraisal

Substantial business resources are being dedicated to information technology (IT) but little is known about the effects of these investments on the performance of firms. This paper reports the results of a study of 33 manufacturing firms' investments in IT and their subsequent performance. The study analysed six years' data collected from three senior officers of each firm. Three types of IT investment were studied: strategic, informational and transactional. While firms which invested heavily in transactional IT were consistently better performers, this effect was not apparent with the other types of IT. These results have policy implications for the methods used to appraise future IT investments. Standard discounted cashflow methods are not suited to all types of IT investments. This article suggests different approaches to IT appraisal for different types of IT investment.     

高管团队内部网络与并购绩效

近年来,高管外部社会网络特征对企业决策的影响受到学术界的广泛关注。与以往研究侧重点不同,本文探究高管团队内部网络结构对企业决策是否产生重大影响,并构建了上市公司高管团队内部网络结构指标。基于社会网络和信息不对称等相关理论,本文实证检验了高管团队内部网络对企业并购决策绩效的影响。结果显示,高管团队内部网络结构密度越高,高管成员之间的沟通越有效,公司并购绩效越好。进一步地分析发现,当并购的复杂度和风险较高、企业所在地区制度环境较差以及高管任职时间较短时,高管团队网络密度对于并购绩效的影响更为明显。最后,本文还发现高管团队内部网络密度高的企业并购后,公司的会计业绩和市场业绩也优于其他公司。

Contagious synchronization and endogenous network formation in financial networks

When banks choose similar investment strategies the financial system becomes vulnerable to common shocks. We model a simple financial system in which banks decide about their investment strategy based on a private belief about the state of the world and a social belief formed from observing the actions of peers. Observing a larger group of peers conveys more information and thus leads to a stronger social belief. Extending the standard model of Bayesian updating in social networks, we show that the probability that banks synchronize their investment strategy on a state non-matching action critically depends on the weighting between private and social belief. This effect is alleviated when banks choose their peers endogenously in a network formation process, internalizing the externalities arising from social learning.     

Common auditors and internal control similarity: Evidence from China

This study investigates how important common auditors are to internal control similarity between two firms. Based on a less concentrated audit market in China, we find that firm-pairs with common auditors enforce a similar internal control system. This inference holds after accounting for other social connections, examining internal control components, using alternative measures of internal control, adopting finer industry classifications, constructing alternative internal control similarity, running auditor switch tests, and addressing endogeneity problems. Additional analyses indicate that auditor style and information sharing serve two underlying mechanisms to undergird the documented relationship. Finally, our evidence suggests that high-centrality firms in auditor networks are associated with better financial reporting.     

Alumni social networks and hedge fund performance: Evidence from China

Based on unique data of Chinese private hedge funds, we first construct the “strong alumni” (alumni of the same school and the same major) social networks of private hedge fund managers, and examine the impact of alumni social networks on the performance of hedge funds in China. We build a series of alumni networks using the educational background information of 4734 private hedge funds, and perform an empirical analysis on a sample of 1115 private hedge funds products from 2010 to 2019. Different from previous findings of mutual funds, we find that more central network positions of hedge fund managers are associated with better risk-adjusted fund performance. Hedge fund managers with more central positions conduct more active investment styles and receive lower fund flows.¹ The results supplement the evidence that information advantages brought by central position in social networks can influence managers' investment styles, thus improve hedge fund performance.     

Social Networks and Corporate Governance

We analyse frameworks that link corporate governance and firm values to governing boards' social networks and innovations in technology. Because agents create social networks with individuals with whom they share commonalities along the dimensions of social status and income, among other attributes, CEOs may participate in board members' social networks, which interferes with the quality of governance. At the same time, social connections with members of a board can allow for better evaluation of the members' abilities. Thus, in choosing whether to have board members with social ties to management, one must trade off the benefit of members successfully identifying high ability CEOs against the cost of inadequate monitoring due to social connections. Further, technologies like the Internet and electronic mail that reduce the extent of face‐to‐face networking cause agents to seek satisfaction of their social needs at the workplace, which exacerbates the impact of social networks on governance. The predictions of our model are consistent with recent episodes that appear to signify inadequate monitoring of corporate disclosures as well as with high levels of executive compensation. Additionally, empirical tests support the model's key implication that there is better governance and lower executive compensation in firms where networks are less likely to form.     

Social capital and capital allocation efficiency

Based on the social norms and structural theories of social capital, this study examines the relationship between community social capital and the firms’ capital allocation efficiency. We hypothesize and find that the community social capital of a firm's headquarter area has a negative and statistically significant impact on its capital allocation inefficiency, which is robust to alternative proxies for community social capital and capital allocation inefficiency, propensity score matching and instrumental variable regressions. In addition, we find that the effect of community social capital is more pronounced for firms with poor internal ethical culture and weak network connections to outside executives and directors, implying that community social capital becomes important in these situations. This finding links prior social norms and networks literature to capital allocation studies in that the norms and networks components of community social capital discipline self-interested managers’ behavior and reduce information asymmetry-two channels of capital allocation efficiency. Overall, community social capital works as a compensatory monitoring and information transfer mechanism and improves the firms’ capital allocation efficiency.
