Busy Venture Capitalists and Investment Performance    [ SSRN ]  

While existing studies confirm venture capitalists’ monitoring ability, evidence of their screening ability remains scarce. To confirm VCs’ screening role, I exploit within-individual variation in VC partners’ workload and attention stemming from engagement in their portfolio companies’ IPOs. I find that when VCs are busy and distracted, they tend to make underperforming investments: startups added to a VC’s portfolio during her IPO engagement period are 9% less likely to go public or become acquired, and they have 19% lower exit multiples. The effects are stronger in cases of higher workload intensity and higher information asymmetry. These results speak to the importance of screening for generating venture capital returns, and point to the meaningful economic tradeoff between engaging with existing companies and screening of new startups.

Do Banks Compete on Non-Price Terms? Evidence from Loan Covenants    [ SSRNwith Christoph Herpfer and Roberto Steri

We investigate the link between competition in credit markets and non-price loan terms, specifically financial covenants. We exploit regulation in the leveraged loan market as variation in banks' ability to offer covenant-lite loans. As regulated banks demand relatively more covenants, borrowers switch to unregulated lenders, or shadow banks, leading to a decline in aggregate banks' market share. Results are not driven by lower loan supply or changes in other loan terms, and reflect a relation between lax covenants and loan growth in the broader lending market. Our findings encourage regulators to internalize non-price competition between regulated and unregulated sectors.

The Value of Privacy and the Choice of Limited Partners by Venture Capitalists [ SSRN ] with Will Gornall and Ilya Strebulaev

We document how information disclosure concerns shape the choice of limited partners by venture capital firms. Late-2002 court rulings forced public pension plans and public university endowments to disclose fund performance information. The most successful, and typically oversubscribed, venture capital firms responded by excluding public institutions from their new funds, replacing them with domestic nonpublic and foreign investors. Public investors reallocated to less successful and younger VC firms, while some of the affected limited partners agreed to limit the scope of disclosure from VC firms. We find no evidence that these changes were driven by the unwillingness to disclose poor technology bubble returns.
