About
I am the David L. and Elsie M. Dodd Professor of Finance at Columbia Business School and co-director of the Private Equity Program. I am also a Research Associate at the National Bureau of Economic Research (NBER), an associate editor at the Review of Financial Studies, Journal of Financial Economics and Journal of Corporate Finance and co-editor of the Journal of Economics & Management Strategy.
I study the financing of high-growth startups and financial intermediation via venture capital and private equity. My research aims to understand if and how financial intermediaries in private equity add value, and when they do, what that teaches us about financing and operational frictions faced by companies.

Local Journalism under Private Equity Ownership
With:
Arpit Gupta and Sabrina Howell (NYU Stern)
Local daily newspapers have historically played an important role in U.S. democracy by providing citizens with information about local policy issues. However, in recent decades local newspapers have struggled to compete with new online platforms for readers’ attention. Private equity investors—who specialize in reorganizing struggling firms in distressed sectors—have entered the industry. How do these new owners affect newspaper content, survival, and local civic engagement? We document nuanced effects, contrasting with the polarized debate on this topic in the media and political discourse. On one hand, we find that private equity ownership leads to higher digital circulation and lower chances of newspaper exit. On the other hand, we document a change in news composition away from information about local governance, and lower employment of reporters and editors. Finally, we find declines in participation in local elections, consistent with local newspaper content being relevant for civic engagement. The results have implications for knowledge about local policy issues and highlight trade-offs surrounding media ownership.

Private or public equity? The evolving entrepreneurial finance landscape
With: Joan Farre-Mensa (Univ. of IL at Chicago)
The U.S. entrepreneurial finance market has changed dramatically over the last two decades. Entrepreneurs raising their first round of venture capital retain 30% more equity in their firm and are more likely to control their board of directors. Late-stage startups are raising larger amounts of capital in the private markets from a growing pool of traditional and new investors. These private market changes have coincided with a sharp decline in the number of firms going public—and when firms do go public, they are older and have raised more private capital. To understand these facts, we provide a systematic description of the differences between private and public firms. Next, we review several regulatory, technological, and competitive changes affecting both startups and investors that help explain how the trade-offs between going public and staying private have changed. We conclude by listing several open research questions.

Venture Capitalists’ Access to Finance and Its Impact on Startups
With: Jun Chen (Renmin Univ.)
Although an extensive literature shows that startups are financially constrained and constraints vary by geography, the source of these constraints is still relatively unknown. We explore a channel studied in the banking literature, but only implicitly addressed in the VC literature: intermediary financing constraints.

Regulatory Costs of Being Public: Evidence from Bunching Estimation
With:
Kairong Xiao (Columbia) and Ting Xu (Univ. of VA)
Working Paper
Consistent with firms seeking to avoid costly regulation, we document significant bunching around multiple regulatory thresholds introduced from 1992 to 2012. We present a revealed preference estimation strategy that uses this behavior to quantify regulatory costs. Our estimates show that various disclosure and internal governance rules leads to a total compliance cost of 4.3% of the market capitalization for a median U.S. public firm.

The Evolution of CEO Compensation in Venture Capital Backed Startups
With:
Ramana Nanda (Imperial) and Christopher Stanton (HBS)
We document new facts on the evolution of founder-CEO compensation in venture capital-backed startups. Having a tangible product (“product market fit”) is a fundamental milestone in CEOs’ compensation, marking the point where liquid cash compensation increases significantly – well before an IPO or acquisition.
