Do Pro‐Diversity Policies Improve Corporate Innovation?

Using new product announcements, patents, and patent citations as measures of corporate innovation, we find that corporate policies that promote more pro‐diversity cultures, specifically treatment of women and minorities, enhance future innovative efficiency. This positive effect is stronger during economic downturns and in firms that are more innovative, value intangibles and human capital more highly, have greater growth options, have higher cash flow, and have stronger governance. Pro‐diversity policies also increase firm value via this stimulating effect on innovative efficiency. Our results suggest a channel through which workforce diversity may enhance firm value.     

Do long‐term institutional investors foster corporate innovation?

This article examines the effect of institutional investors’ investment horizons on firms’ innovation activities. We conjecture that the presence of long‐term institutional investors mitigates managerial myopia, prompting firms to generate greater corporate innovation outputs. Using data on patents and patent citations for US firms, we find that institutions’ investment horizons are positively related to the number of patents and patent citations. We also document that long‐term (short‐term) institutional ownership is positively (negatively) related to the innovation outputs. This article makes an additional contribution to the corporate innovation literature by addressing the positive role of long‐term institutional investors.     

Innovation and Price Informativeness

We study whether the innovation decisions of a firm are improved as a result of information reflected in the firm's stock price. We show that firms with more informative stock prices, as measured by price nonsynchronicity, have better innovation outcomes, as measured by the number of patents and patent citations. Our results are not driven by managerial private information and are robust to various alternative specifications. We also find that price informativeness is more important to innovation when managers are less experienced or face greater uncertainty about the optimal innovation strategy, and that these effects are primarily observed in small‐ and mid‐sized firms where additional information may be of greater value. Our results are consistent with the notion that capital markets can have real effects on the economy.     

Do Managers Use Meeting Analyst Forecasts to Signal Private Information? Evidence from Patent Citations

This study examines whether firms manage earnings to meet analyst forecasts to signal superior future performance. Prior research finds that firms use earnings management to just meet analyst forecasts and that these firms have a positive association with future performance (Bartov et al., 2002). There are two potential explanations for the positive association – signaling and attaining benefits that allow for better future performance (i.e., the real benefits explanation). Prior studies cannot provide evidence of signaling because they do not control for the real benefits explanation. Our research design enables us to control for the real benefits explanation because we can identify potential signaling firms within the sample of firms that just meet analyst forecasts. We use a unique database from the National Bureau of Economic Research to construct a proxy for the manager's belief about future firm value due to patents. We find that firms with more patent citations are more likely to just meet the analyst forecast and manage earnings to achieve this goal. We also find firms that just meet analyst forecasts with more patent citations have significantly better performance than firms with fewer patent citations, which is consistent with signaling and not the real benefits explanation.     

The influence of corporate social responsibility on investment efficiency and innovation

We examine two important channels through which corporate social responsibility (CSR) affects firm value: investment efficiency and innovation. We find that firms with higher CSR performance invest more efficiently: these firms are less prone to invest in negative net present value (NPV) projects (overinvestment) and less prone to forego positive NPV projects (underinvestment). We also find that firms with higher CSR performance generate more patents and patent citations. Mediation analysis indicates that firms with higher CSR performance are more profitable and valuable, consequences partially attributable to efficient investments and innovation. These results, robust to alternate model specifications, lend support to enlightened stakeholder theory.     

Do alliances promote knowledge flows?

We explore the role of interfirm alliances as a mechanism for sharing technological knowledge. We argue that knowledge flows between alliance partners will be greater than flows between pairs of nonallied firms, and less than flows between units within single firms. Using patent citations as a proxy for knowledge flows, we find results that are consistent with these expectations. We then explore how firm characteristics affect knowledge flows within alliances and find positive effects due to technological, geographic, and business similarities between partners. We use alliance data from MERIT, patent data from the USPTO, and firm data from Compustat.     

Are Overconfident CEOs Better Innovators?

Previous empirical work on adverse consequences of CEO overconfidence raises the question of why firms hire overconfident managers. Theoretical research suggests a reason: overconfidence can benefit shareholders by increasing investment in risky projects. Using options‐ and press‐based proxies for CEO overconfidence, we find that over the 1993–2003 period, firms with overconfident CEOs have greater return volatility, invest more in innovation, obtain more patents and patent citations, and achieve greater innovative success for given research and development expenditures. However, overconfident managers achieve greater innovation only in innovative industries. Our findings suggest that overconfidence helps CEOs exploit innovative growth opportunities.     

Tariff uncertainty and firm innovation: Evidence from the U.S.–China Permanent Normal Trade Relation

We examine the effect of the tariff uncertainty associated with Chinese imports on U.S. firm innovation. Our test exploits the U.S. conferral of Permanent Normal Trade Relations (PNTR) on China—a policy that reduces the uncertainty of future tariff increases for Chinese goods. We find a significant increase in the number of patents and patent citations for U.S. firms affected by PNTR relative to other firms. This result is stronger for firms with more irreversible investments and for firms that experience a greater increase in Chinese goods following PNTR. Overall, our evidence is consistent with the view that lowering the tariff uncertainty of Chinese imports boosts the attractiveness for U.S. firms to make long-term irreversible investment (such as technological innovation) and thus induces U.S. firms to innovate more.     

The effect of tax avoidance crackdown on corporate innovation

To constrain the use of intangible assets in tax-motivated state income shifting, many U.S. state governments adopted addback statutes. Addback statutes reduce the tax benefits that firms can gain from creating intangible assets such as patents. Using a sample of U.S. public firms, we examine the effect of addback statutes on corporate innovation behavior. First, the adoption of addback statutes leads to a 4.77 percentage point decrease in the number of patents and a 5.12 percentage point decrease in the number of patent citations. Second, the “disappearing patents” resulting from addback statutes have significant economic value. Third, after a state adopts an addback statute, a firm with material subsidiaries in that state assigns fewer patents to subsidiaries in zero-tax states, whereas the number of patents assigned to the other states does not change. Overall, our findings suggest that addback statutes impede corporate innovation.     

Reverse innovation and firm value in emerging markets: Evidence from China

Reverse innovation (RI) patents, which apply to intellectual property that is created in an emerging country but patented in a developed country, are better representatives of innovation value than domestic patents in emerging economies. We argue that RI patents contribute to firm value by proxying for the private value of innovation, generating product market value, and signalling firms’ capabilities. Using a sample of Chinese-listed companies, we find RI patents positively relate to firms’ short- and long-term market value. This effect is stronger for firms with high innovative intensity and managerial ability. We also explore the mechanisms behind the relationship between RI and firm value. We demonstrate that, in addition to the domestic patent functions of creating value and capturing innovation rent, RI patents can further leverage firm value by signalling firm quality to customers and investors in developed markets, a function that is unique to RI patents.     

专利提前公开的资本市场动因——基于企业被并购压力视角的研究

随着我国资本市场建设的日益完善,上市公司控制权市场活跃度得到显著提升,企业如何应对被并购压力成为值得关注的议题。本文研究企业是否会选择发明专利公开时点来应对被并购压力。研究发现,当被并购压力增大时,上市公司会越早公开专利。这是因为专利提前公开能够提升公司股票的异常回报,从而降低企业成为被并购目标的可能性或提高企业可获得的并购溢价。异质性分析发现:(1)被并购压力增大时,既有分析师关注度和风险投资者持股比例越高的企业越可能提前公开专利;(2)企业更可能选择技术成熟、质量较高的专利进行公开;(3)其他替代策略的存在会削弱被并购压力对专利提前公开的影响。在使用工具变量、行业并购政策变化和举牌事件作为外生冲击对内生性问题进行处理后,结果仍然稳健。     

改进型创新抑或突破型创新——基于客户集中度的视角

本文从客户集中度的视角考察其究竟是促进了企业的改进型创新抑或突破型创新。研究结果表明,企业的客户集中度越高,其越倾向于进行突破型创新,但是这种关系只在国有企业以及与主要客户地理位置相似度比较高的企业中显著;对发明专利和实用新型专利分别进行检验的结果表明,在国有企业以及与主要客户地理位置相似度比较高的企业中,客户集中度的提高有助于增加企业申请的发明专利数量,但是并不会对企业申请的实用新型专利数量产生影响。本文的研究不仅为客户集中度究竟是促进了企业改进型创新抑或突破型创新的不同观点提供了一定的经验证据,而且对于我国推进制造强国战略、促进企业转型升级具有重要的启示意义。     

Independent boards and innovation

Much research has suggested that independent boards of directors are more effective in reducing agency costs and improving firm governance. How they influence innovation is less clear. Relying on regulatory changes, we show that firms that transition to independent boards focus on more crowded and familiar areas of technology. They patent and claim more and receive more total future citations to their patents. However, the citation increase comes mainly from incremental patents in the middle of the citation distribution; the numbers of uncited and highly cited patents—arguably associated with riskier innovation strategies—do not change significantly.     

Employee treatment and firm innovation

We identify firm innovation as a channel through which the treatment of employees affects firm value. Long‐term incentive theory supports positive effects of ‘good’ employee treatment on innovation. Alternatively, entrenchment theory suggests such treatment will lead to complacency and shirking, hence deterring innovation. These opposing views merit investigation since human capital is increasingly essential to the growth and success of a firm. Using the KLD database and patent/citation data, we find a significant positive relationship between favorable employee treatment and the innovation quantity and quality of a firm. Furthermore, we find that the positive treatment of employees improves innovation focus – more innovation related to firms’ core business, leading to greater firm value via the increased economic value of patents. These findings, robust to endogeneity concerns, provide support for the long‐term incentive hypothesis, suggesting that well‐treated employees increase firm innovation. Thus, firm innovation represents a channel through which positive employee treatment enhances firm value.     

Financial reporting quality and corporate innovation

This paper examines the relationship of financial reporting to corporate innovation. Given the importance of a high‐quality information system and coordination to innovation, I predict a positive association between financial reporting quality and future innovation. My empirical evidence is consistent with this prediction. I also find some evidence that the positive association between financial reporting quality and innovation is more pronounced for firms with intensive internal research and development activities and for firms in competitive industries. The main findings are robust to using an instrumental variable approach as well as controlling for alternative explanations. I find that firms with high‐quality financial reporting transform investment inputs into greater innovation outcomes and firm value. This study provides additional insight into the role of financial reporting quality and its relation to the real economy.     

Do Hostile Takeovers Stifle Innovation? Evidence from Antitakeover Legislation and Corporate Patenting

I examine how strong corporate governance proxied by the threat of hostile takeovers affects innovation and firm value. I find a significant decline in the number of patents and citations per patent for firms incorporated in states that pass antitakeover laws relative to firms incorporated in states that do not. Most of the impact of antitakeover laws on innovation occurs 2 or more years after they are passed, indicating a causal effect. The negative effect of antitakeover laws is mitigated by the presence of alternative governance mechanisms such as large shareholders, pension fund ownership, leverage, and product market competition.     

Capitalizing R&D expenses versus disclosing intangible information

We study how to improve the value-relevance of financial information for intangible-intensive firms by investigating two alternatives: capitalizing research and development (R&D) expenses and disclosing intangible information. Using patent counts/citations to proxy for intangible intensity, we find that the incremental value-relevance of disclosing patent counts/citations is greater than that of capitalizing R&D expenses for the high-patent group and vice versa for the low- or medium-patent group. Investors favor the disclosure of patent information for firms with more successful innovations. Since disclosing intangible information may lead to appropriation by rivals, we find that, for the high-patent group, the incremental value-relevance of disclosing patent counts/citations is more pronounced for firms in industries with stronger protection of intellectual property. Overall, our results suggest that disclosing R&D outputs can improve the value-relevance of financial statements for firms rich in intangibles and the incremental benefits of such disclosure will be greater in industries with strong protection of intellectual property.     

IPO anomalies and innovation capital

Innovation capital are typically expensed and/or unrecognized as assets under current generally accepted accounting principles. This results in accounting-related information asymmetry. This paper examines the association of innovation capital (as measured here by the proxies of R&D expenditures and granted patents) and initial public offerings (IPO) anomalies. These anomalies include initial IPO underpricing, duration of honeymoon (a distinct feature of the Taiwanese IPO environment), and long-term performance. The theoretical model underlying this research is a signaling model. The results indicate that more innovative firms are more likely to be underpriced, and have longer honeymoon periods than less innovative firms. Further, the more innovative firms have positive and growing long-term market-adjusted returns. This stands in contrast to the declining long-term stock performance of initial public offering firms that is evidenced in the literature. We conclude that pre-IPO research and development expenditures disclosed in the IPO prospectus, official monthly reports of newly developed patents released to the public, and the frequency of patent citations significantly signal both underpricing and future market performance of IPO firms in Taiwan.

Option-implied information and quality of patents

This research explores how option-implied information predicts quality of patents. Using several measures of option-implied information, we find that only the option to stock volume (O/S) ratio positively and significantly predicts quality of patents around patent grant announcements. The findings are not entirely driven by information from the stock market and the probability of informed trading. Further investigations show that the predictability of O/S on patent quality is stronger when market sentiment is high, firms have a higher short-sale cost, and the quality of patents is relatively high.
