Peer Effects

  • 详情 Peer Effects in Influencer-Sponsored Content Creation on Social Media Platforms
    To specify the peer effects that affect influencers’ sponsored content strategies, the current research addresses three questions: how influencers respond to peers, what mechanisms drive these effects, and the implications for social media platforms. By using a linear-in-means model and data from a leading Chinese social media platform, the authors address the issues of endogenous peer group formation, correlated unobservables, and simultaneity in decision-making and thereby offer evidence of strong peer effects on the quantity of sponsored content but not its quality. These effects are driven by two mechanisms: a social learning motive, such that following influencers emulate leading influencers, and a competition motive among following influencers within peer groups. No evidence of competition motive among leading influencers or defensive strategies by leading influencers arises. Moreover, peer effects increase influencers’ spending on in-feed advertising services, leading to greater platform revenues, without affecting the pricing of sponsored content. This dynamic may reduce influencers’ profitability, because their rising costs are not offset by higher prices. These findings emphasize the need for balanced strategies that prioritize both platform growth and influencer sustainability. By revealing how peer effects influence competition and revenue generation, this study provides valuable insights for optimizing content volume, quality, and financial outcomes for social media platforms and influencers.
  • 详情 Greenwashing or green evolution: Can transition finance empower green innovation in carbon-intensive enterprise?
    The scale expansion of low-carbon industries and the green transformation of carbon-intensive industries are two sides of the same coin in achieving the “dual carbon” goals. However, research on transition finance supporting the upgrading of traditional existing carbon-intensive industries remains insufficient. The key to examining the effectiveness of transition finance lies in distinguishing whether the supported enterprises are engaging in greenwashing or green evolution. Based on data of Chinese A-share listed companies in the carbon-intensive industries, an empirical study is conducted and offers the following findings: (1) Transition finance not only does not increase greenwashing but also promotes comprehensive green innovation in carbon-intensive enterprises. (2) In terms of the influencing mechanism, transition finance exerts “resource effects” and “signaling effects,” promoting green innovation by improving debt maturity mismatch and attracting green institutional investors. (3) Heterogeneity analysis shows that the positive impact of transition finance on green innovation is particularly pronounced among enterprises in the eastern region, state-owned enterprises, and those with lower levels of managerial myopia. (4) Further industry spillover effects analysis reveals that transition finance empowers green innovation within industries though peer effects and competitive effects. The findings are essential for understanding the effectiveness of transition finance and offer valuable insights for policymakers.
  • 详情 Punish One, Teach A Hundred: The Sobering Effect of Peer Punishment on the Unpunished
    Direct experience of a peer’s punishment might have a sobering effect above and beyond deterrence (information about punishments). We test this mechanism in China studying the reactions to listed state-owned enterprises’ (SOEs) punishments for fraudulent loan guarantees by firms in the same location or industry (peers) and non-peer firms, across SOEs and non-SOEs. After experiencing SOEs’ punishments, peer SOEs cut their loan guarantees by more than non-peer SOEs and peer non-SOEs, even if information is common to all firms. The reaction is stronger for peer SOEs whose CEOs have higher career concerns or face lower costs of cutting guarantees.
  • 详情 The Influence of Peers' Md&A Tone on Corporate Cash Holdings
    We explore whether Management Discussion and Analysis (MD&A) can provide incremental information to peers. Using Chinese stock market data, we find that positive peers' MD&A tone encourages firms to hold more cash, particularly for industries with fewer institutional investors' site visits. Moreover, this association is moderated by predation risk and decision-making environment. Specifically, this effect is more pronounced for firms which are market followers or financial constrained, and it is also stronger for firms operating under higher economic policy uncertainty or solely in domestic market. Overall, our findings enrich the information channels of peer effects in cash policy.
  • 详情 Media Coverage of Start-ups and Venture Capital Investments
    Using a large sample of over 5,000 start-ups across various industries and 524 media outlets in China between 2000 and 2016, we examine the effects of media coverage of start-ups on VC investment decisions and performance. To the best of our knowledge, for the first time in the finance literature, we have discovered that media coverage of start-ups significantly affects VC investment decisions and exit performance. Specifically, such coverage, especially positive coverage, significantly increases the probability and amount of VC investments in start-ups. It also significantly improves the exit performance of VC investments. The significant effects of media coverage of start-ups on VC investments are driven by market-oriented instead of state-controlled media. We further find that VC investments in a focal start-up are significantly influenced by the average media coverage of other start-ups in the same industry or the same city. Our results are robust to a battery of robustness tests. Our research contributes to the behavioral finance literature by showing that an increasingly prominent type of institutional investors, venture capitalists, just like individual investors, are also subject to limited attention. Our research also extends the research by You, Zhang and Zhang (2018) by revealing the heterogeneous effects of market-oriented and state-controlled media on VC investments. Last but not the least, we are the first to discover that peer start-ups’ media coverage matters for VC investments in the focal firms, thereby pushing the frontier of research on the roles of media in finance.
  • 详情 Peer Effects in the Trading Decisions of Individual Investors
    This study examines for evidence of peer effects in the trading decisions of individual investors from Mainland China, a country whose cultural and social structures are vastly different from those of Western countries. Cultural differences, as widely documented, play a significant role in social interactions and word-of-mouth behavior. In contrast to U.S. studies, we find robust evidence that the trading decisions of Chinese investors are influenced, via word-ofmouth, by those of their peers who maintain brokerage accounts at the same branch, but not by those whose accounts are maintained at another branch located in the same city.
