This paper investigates the spectacular rise and fall of structured finance. HBS professor Joshua Coval, Princeton professor Jakub Jurek, and HBS professor Erik Stafford begin by examining how the structured finance machinery works. They construct simple examples of collateralized debt obligations (CDOs) that show how pooling and tranching a collection of assets permits credit enhancement of the senior claims. They then explore the challenge faced by rating agencies, examining, in particular, the parameter and modeling assumptions that are required to arrive at accurate ratings of structured finance products. They conclude with an assessment of what went wrong and the relative importance of rating agency errors, investor credulity, and perverse incentives and suspect behavior on the part of issuers, rating agencies, and borrowers.

Pooling economic assets into large portfolios and tranching them into sequential cash-flow claims has become a big business, generating record profits for both the Wall Street originators and the agencies that rate these securities. This paper by business economics doctoral student Jakub Jurek and HBS professors Joshua Coval and Erik Stafford investigates the pricing and risks of instruments created as a result of recent structured finance activities. It demonstrates that senior collateralized debt obligation (CDO) tranches have significantly different systematic risk exposures than their credit rating-matched, single-name counterparts, and should therefore command different risk premia.

Money managers work in a stressful, competitive pressure cooker that's hard to appreciate from the safety of a business management classroom. That's why HBS professors Joshua Coval and Erik Stafford invented upTick—a market simulation program that has students sweating and strategizing as they recreate classic market scenarios.

Researchers and participants in the market for securities have long been interested in the costs of transacting and the notion of liquidity as a performance measure of market structure. In real world capital markets, investors and corporations generally do not expect to transact at fundamental value. Rather, market participants face some degree of illiquidity, where they must sacrifice price, trade size, or speed of execution, forcing them to transact at prices away from fundamental value. The exact price of liquidity, however, is unknown. This paper develops an option-based model of the price of liquidity via the pricing of limit orders.
