Investing with the Government: A Field Experiment in China

Journal of Political Economy 2024 132(1), 248-294 open access
We conduct a large-scale, nondeceptive field experiment to elicit preferences for government participation in China's venture capital and private equity market. Our main result is that the average firm dislikes investors with government ties. We show that such dislike is not present with government-owned firms and that this dislike is highest with best-performing firms. Additional results and surveys suggest that political interference in decision-making is the leading reason why government investors are unattractive to private firms. Overall, our findings point to the limits of a model of “state capitalism” that strongly relies on the complementarity between private firms and government capital to drive high-growth entrepreneurship and innovation.

Bank regulation, financial crisis, and the announcement effects of seasoned equity offerings of US commercial banks

Journal of Financial Stability 2016 25, 37-46 open access
This paper studies the differences in the announcement effects of seasoned equity offerings (SEOs) of commercial banks and non-banks, and explores the influence of bank regulation and the financial crisis on such differences. We find that abnormal stock returns on SEO announcements for US commercial banks are significantly higher than those of non-banks, consistent with the hypothesis that bank regulations reduce the likelihood that bank SEOs signal overpriced equity. The propensity score matching-based difference-in-difference analysis indicates that the differences in stock returns between banks and non-banks decreased during the 2007–2009 financial crisis period and increased after the passage of the Dodd-Frank Act in 2010.

Common ownership and innovation efficiency

Journal of Financial Economics 2023 147(3), 475-497 open access
How does common ownership affect innovation? We study this question using project-level data on pharmaceutical startups and their venture capital (VC) investors. We find that common ownership leads VCs to hold back projects, withhold funding, and redirect innovation at lagging startups. Effects are stronger where R&D costs are larger, consistent with common owners aiming to cut duplicate costs. Effects are also stronger where technological similarity is greater and preexisting competition is lower, consistent with common owners seeking market power for their surviving projects. Overall, common VC ownership appears to generate social benefits , via improved innovation efficiency, but also social costs.

Does common ownership raise antitrust concerns?

Journal of Corporate Finance 2026 100, 103037 open access
Common ownership has raised growing antitrust concerns. We compile a comprehensive dataset of U.S. antitrust litigation cases from the Federal Trade Commission, the Department of Justice, and consumer-initiated lawsuits to shed light on these concerns. We find no robust relationship between common ownership of firm-pairs and the likelihood of these firms being jointly sued. Furthermore, common ownership is negatively associated with potential channels of collusion, such as interlocking directors and competitor-benchmarked executive pay. Evidence from institutional mergers and S&P 500 additions of rival firms supports our main conclusions. Overall, our results offer little support for the view that common ownership promotes explicit collusion.

Geographic proximity and trade credit: Evidence from a quasi-natural experiment

Journal of Corporate Finance 2024 84, 102535 open access
This paper examines the impact of geographic proximity on suppliers' decisions to provide trade credit to their customers. To establish a causal relationship, we utilize the implementation of high-speed rail (HSR) services in China as a quasi-natural experiment. Our findings reveal a significant increase in trade credit received by firms after introducing HSR services. We propose and test three mechanisms to elucidate the influence of proximity on trade credit provision: the enhanced convenience for acquiring soft information, heightened competition among suppliers, and the potential development of social trust. Empirical evidence strongly supports the first two mechanisms, underscoring their importance in shaping trade credit decisions. However, limited evidence is found regarding the role of social trust. These findings contribute to understanding the complex interplay between geographic proximity, trade credit, and supplier decision-making processes.

Exchange-Traded Funds and Real Investment

Review of Financial Studies 2023 36(3), 1043-1093 open access
We investigate the link between exchange-traded funds and real investment. Cross-sectionally, higher ETF ownership is associated with an increased sensitivity of real investment to Tobin’s q and a heightened ability of stock returns to forecast future earnings. Inclusion of stocks in industry ETFs enhances investment-q sensitivity and implies greater incorporation of earnings information into prices prior to public releases. Greater nonmarket ETF ownership leads to increased (reduced) reliance of real investment on own (peers’) stock prices. Overall, the evidence is consistent with ETFs positively affecting real investment efficiency via greater flows of information.

Institutional dual holdings and expected crash risk: Evidence from mergers between lenders and equity holders

Contemporary Accounting Research 2024 41(3), 1819-1850 open access
Exploiting mergers between lenders and shareholders of the same firm as an exogenous shock to shareholder–creditor conflicts, we examine the causal effect of these conflicts on firms' ex ante expected stock price crash risk evident in the options implied volatility smirk. The decrease in conflicts of interest between lenders and shareholders induces dual holders to encourage the disclosure of more information to alleviate costly information asymmetry with other investors and better execute their oversight role in constraining managers' bad news suppression. Consistent with expectations, we find that a firm's ex ante expected crash risk declines after a shareholder–creditor merger. We also report strong, robust evidence that the negative impact of mergers on firms' expected crash risk increases when institutional investors or lenders have a greater stake in the treatment firms or when shareholder–creditor conflicts are apt to be exacerbated. Additionally, we document that firms issue management earnings forecasts (especially bad news forecasts) more frequently after these mergers. Finally, we find that expected crash risk decreases more after mergers in firms suffering worse information asymmetry and with weak monitoring mechanisms. Our evidence suggests that option market participants value the dual holder's role in deterring managers' bad news hoarding.

Does the Threat of a PCAOB Inspection Mitigate US Institutional Investors' Home Bias?*

Contemporary Accounting Research 2021 38(4), 2622-2658 open access
ABSTRACT We exploit the staggered introduction of the PCAOB's international inspection program to examine the role that the stringency of public audit oversight plays in shaping US institutional investors' home bias. Analyzing a sample of foreign firms listed in the United States, we evaluate whether US institutional investors hold larger equity stakes in these firms—a longstanding issue that reflects investor portfolio decisions—if their auditors are exposed to the threat of a PCAOB inspection. In a differences‐in‐differences framework, we find that US‐listed foreign firms enjoy an increase in US institutional investors' equity positions after their auditors become subject to PCAOB inspection access. Cross‐sectional analysis implies that the benefit of the PCAOB inspection threat in mitigating US institutional investors' home bias is concentrated in foreign countries without a strict local audit oversight system; active US institutional investors that are known to value accounting transparency; and firms from countries that grant PCAOB access later (after the onset of its international inspection program in 2005). Our evidence suggests that foreign firms become better known in the capital markets under the PCAOB inspection program, which induces US institutional investors to acquire larger equity stakes in US‐listed foreign firms given the lower information asymmetry that ensues under the PCAOB inspection threat.

Asset Pricing with Cohort‐Based Trading in MBS Markets

Journal of Finance 2022 77(6), 3249-3287 open access
ABSTRACT Agency mortgage‐backed securities (MBSs) with diverse characteristics are traded in parallel through individualized specified pool (SP) contracts and standardized to‐be‐announced (TBA) contracts with delivery flexibility. This parallel trading environment generates distinctive effects on MBS pricing and trading: (i) Although cheapest‐to‐deliver (CTD) issues are present in TBA trading and absent from SP trading by design, MBS heterogeneity associated with CTD discounts affects SP yields positively, with the effect stronger for lower‐value SPs; (ii) high selling pressure amplifies the effects of MBS heterogeneity on SP yields; and (iii) greater MBS heterogeneity dampens SP and TBA trading activities but increases their ratio.

Consolidating Product Lines via Mergers and Acquisitions: Evidence From the USPTO Trademark Data

Journal of Financial and Quantitative Analysis 2022 57(8), 2968-2992 open access
Using a new trademark-based product market competition measure and a novel trademark-merger data set over the period 1983–2016, we show that companies facing greater product market competition are more likely to be acquirers. We further show that postmerger, compared to their nonacquiring peers, acquirers consolidate their product offerings by discontinuing more existing product lines and developing fewer new product lines. Using a quasi-experiment based on bids withdrawn due to exogenous reasons helps us establish the causal effect of deal completion on product-market consolidation. We conclude that acquisitions create product market synergies by cutting overlapping product offerings to achieve cost efficiency.
