Corporate Finance

Entrepreneurs face significant nondiversifiable business risks. We build a dynamic incomplete markets model of entrepreneurial firms to demonstrate the important implications of nondiversifiable risks for entrepreneurs' interdependent consumption, portfolio allocation, financing, investment, and business exit (cash-out and default) decisions. The optimal capital structure is determined by a generalized tradeoff model where risky debt provides significant diversification benefits.

The first hints of trouble in the mortgage market surfaced in mid-2005, and conditions subsequently began to deteriorate rapidly. Mortgage defaults and delinquencies are particularly concentrated among borrowers whose mortgages are classified as "subprime" or "near-prime." The main factors underlying the rise in mortgage defaults appear to be declines in house prices and deteriorated underwriting standards, in particular an increase in loan-to-value ratios and in the share of mortgages with little or no documentation of income.

It was Thursday August 19, 2004, and after months of anticipation, trading of Google stock would finally begin this morning on the NASDAQ. Google offered a total of 19,605,052 Class A shares using a "modified" Dutch auction initial public offering (IPO), including 14,142,135 floated by Google and 5,462,917 from existing stockholders, at a price range of $85-$95 per share. You have been charged with advising ReidCourt LLC as to whether it should bid to purchase Google shares in the IPO, and if so, at what price(s).

This book describes valuation as an exercise in financial statement analysis. Students learn to view a firm through its financial statements and to carry out the appropriate financial statement analysis to value the firm's debt and equity. The book takes an activist approach to investing, showing how the analyst challenges the current market price of a share by analyzing the fundamentals. With a careful assessment of accounting quality, accounting comes to life as it is integrated with the modern theory of finance to develop practical analysis and valuation tools for active investing.

Previous research concludes that options are mispriced based on the high average returns, CAPM alphas, and Sharpe ratios of various put selling strategies. One criticism of these conclusions is that these benchmarks are ill suited to handle the extreme statistical nature of option returns generated by nonlinear payoffs. We propose an alternative way to evaluate the statistical significance of option returns by comparing historical statistics to those generated by option pricing models.

As the record of Fed interventions from December 2007 to December 2008 make abundantly clear, a foremost concern of monetary authorities in responding to the financial crisis has been to avoid a repeat of the great depression, and especially a repeat of the monetary contraction identified as the major cause of the 1930s depression.

Affine jump-diffusion (AJD) processes constitute a large and widely used class of continuous-time asset pricing models that balance tractability and flexibility in matching market data. The prices of e.g., bonds, options, and other assets in AJD models are given by extended pricing transforms that have an exponential-affine form; these transforms have been characterized in great generality by Duffie et al. [2000. Transform analysis and asset pricing for affine jump-diffusions. Econometrica 68, 1343–1376].

Financial innovations often respond to regulation by sidestepping regulatory restrictions that would otherwise limit activities in which people wish to engage. Securitization of loans (e.g., credit card receivables, or subprime residential mortgages) is often portrayed, correctly, as having arisen in part as a means of "arbitraging" regulatory capital requirements by booking assets off the balance sheets of regulated banks.

We investigate pricing effects of the joint production of loans and security underwritings. We control for firm and borrower characteristics, including differences in sequencing, which are important for pricing. Contrary to previous studies, when banks combine lending and underwriting within the same customer relationship they charge premiums for both loans and underwriting services. Abstracting from effects of joint production within relationships, depository banks engaged in underwriting price lending and underwriting more cheaply than stand alone investment banks.
