Relationship capital and financing decisions
(with Thomas Geelen and Natalyia Rostova)
In a model of debt dynamics, we study how lending relationships are formed and how they impact leverage and debt maturity choices. Stronger lending relationships lead firms to adopt higher leverage ratios, issue longer term debt, and raise funds from non-relationship lenders when relationship quality is sufficiently high. The maturity of debt contracts issued to non-relationship investors is higher than that of relationship investors. Negative shocks to relationship lenders drastically affect the financing choices of firms with intermediate relationship quality.

Screening and monitoring corporate loans
(with Sebastian Gryglewicz and Simon Mayer)
Dynamic moral hazard problem in which a bank originates a pool of loans to sell them to investors. The bank controls the loans’ default through screening at origination and monitoring after origination, both of which are subject to moral hazard. Screening and monitoring incentives are provided by exposing the bank to loan performance. As screening occurs only once at origination, incentives are front-loaded. The optimal contract can be implemented via time-decreasing stake in the loan pool so that incentives to monitor decrease and credit default risk increases over time. Credit ratings distort incentives, potentially increasing credit risk. They are particularly beneficial for firms that implement long-term financing by rolling over short-maturity loans.

Takeover protections and stock returns
(with Assaf Eisdorfer and Alexei Zhdanov)
Takeover protections decrease shareholder value and increase equity risk and stock returns by removing the option to sell equity when firms approach financial distress. In line with our predictions, distressed firms experience a significant decrease in  value and increase in returns and market betas after the passage of anti-takeover laws, both domestically and internationally.

Principles of Finance

This course is intended to provide a market-oriented framework for analyzing the major types of financial decisions made by corporations. Lectures and readings will provide an introduction to present value techniques, capital budgeting principles and problems, asset valuation, the operation and efficiency of financial markets, the financial decisions of firms, and derivatives. Throughout the class, we will solve problems to enhance our understanding of the covered topics.

Dynamic Corporate Finance (SFI PhD program)

This course is designed to provide a framework for understanding the determinants of corporate financing, dividend, hedging, investment, and compensation policies. The course will provide both an economic analysis of the determinants  of each policy and a quantitative analysis of the effects of these determinants. There is no required textbook. Readings will be based on scientific articles. Topics covered: Real options; Dynamic contracting; Dynamic adverse selection; Financing frictions; Dynamic capital structure models with and without commitment; Runs
