FIN 721 - Corporate Finance

This course continues the development of the principles of finance begun in Bus-Fin 620. The course briefly (sessions 2 – 5) reviews the concepts learned in 620 – such as time value of money, net present value rules, and simple capital budgeting problems. The effects of market imperfections are crucial in many of these decisions. The course puts it all together and revisit investment decisions to determine how we must alter the capital budgeting rules of Bus-Fin 620 to account for market imperfections.

  • The Rise and Fall of Securitization
    with Sam Hanson and Adi Sunderam
    Abstract: The rise and fall of nontraditional securitizations—collateralized debt obligations and mortgage-backed securities backed by nonprime loans—played a central role in financial crisis. Little is known, however, about the factors that drove the pre-crisis surge in investor demand for these products. Examining insurance companies' and mutual funds' holdings of fixed income securities, we find evidence suggesting that both agency problems and neglected risks played an important role in driving investor demand for nontraditional securitizations prior to crisis. We also use our holdings data to shed light on the factors that drove the dramatic collapse of securitization markets beginning in mid-2007. Contrary to conventional crisis narratives, we find little evidence of widespread fire sales. Instead, our evidence is more consistent with the idea that a self-amplifying buyers' strike drove the dramatic collapse of securitization markets.
  • Frictions in Shadow Banking: Evidence from the Lending Behavior of Money Market Funds with Adi Sunderam (This paper was previously circulated under the title The Quiet Run of 2011: Money Market Funds and the European Debt Crisis)
    Abstract: We document the consequences of money market fund risk taking during the European sovereign debt crisis. Using a novel data set of security-level holdings of prime money market funds, we show that funds with large exposures to risky Eurozone banks suffered significant outflows between June and August 2011. Due to credit market frictions, these outflows have significant spillover effects on other firms: non-European issuers that typically rely on these funds raise less financing in this period. The results are not driven by issuers' riskiness or exposure to Europe: for the same issuer, money market funds with greater exposure to Eurozone banks decrease their holdings more than other funds. We show that relationships are important in short-term credit markets so that these spillover effects cannot be seamlessly offset, even though issuers are large, highly rated firms. Our results illustrate that instabilities associated with money market funds persist despite recent changes to the regulations governing them.
  • Arbitrage Capital and Real Investment
    with Adi Sunderam
    Abstract: We study the relationship between the supply of arbitrage capital and real investment. The investment of firms that depend on convertible debt for financing responds positively to flows into convertible arbitrage hedge funds. An extra $1 of fund flows increases capital expenditures of convertible dependent firms by $0.49. At the same time, convertible arbitrage strategy returns are uncorrelated with the stock returns of convertible dependent firms. Moreover, fund flows respond positively to lagged strategy returns but not to lagged returns of dependent firms, suggesting that the supply of capital is not driven by changes in firm investment opportunities. We also examine an isolated market dislocation that occurred in 2005 when funds suffered large withdrawals. Though the macroeconomic outlook was positive and stable, dependent firms sharply cut their investment in response to the withdrawal of capital, with the overall reduction in capital expenditures amounting to 55% of outflows. Our results suggest that firm investment responds to shocks to the supply of arbitrage capital.
