What is private equity?
Private capital markets play an increasingly important role in the U.S. and the broader economy, from private equity and venture capital to growth equity and private credit. Each asset class has economics that differ from its public-market counterpart. The closed-end fund, for example, introduces a host of contracting incentives and information challenges. Delegation therefore runs throughout research on private equity. Investors commit capital over long periods, with limited liability, liquidity, and information. Rather than relying on prices, they rely on valuations, often provided at managers' discretion. These stark differences from public markets form the foundation of this PhD session, which provides an overview of key themes in contemporary research and a framework for researchers exploring new and unanswered questions.
Teaching objectives
- Describe the key facts, institutional details, and central results of the private equity literature, anchored in its seminal papers.
- Explain the economic and institutional differences between private and public capital markets, and analyze why those differences matter for both firms and researchers.
- Critique the theoretical and empirical research designs the field uses — selection versus treatment, missing prices, self-reported valuations — and the limits they impose on what we can know.
- Assess how private-market data come to exist — who reports them, and why — before drawing inferences from them.
- Formulate dissertation-ready research questions from the field's open questions.
