This paper presents a novel and practical non-parametric approximate dynamic programming (ADP) algorithm that enjoys graceful, dimension-independent approximation and sample complexity guarantees. In particular, we establish both theoretically and computationally that our proposal can serve as a viable replacement to state of the art parametric ADP algorithms, freeing the designer from carefully specifying an approximation architecture. We accomplish this by "kernelizing" a recent mathematical program for ADP (the "smoothed" approximate LP) proposed by Desai et al. (2011).

This paper uses a Pragmatic theory of language (drawn from philosophy and linguistics) to diagnose the causes of excessive financial disclosure and propose a regulatory solution. The diagnosis is that existing disclosure regulations are one sided, effectively encouraging firms to disclose any information that might be relevant, but failing to discourage disclosure of information that adds little to what investors already know.

In August 2009 Marvel Entertainment considers a merger with the Walt Disney Company. If Marvel shareholders approve the deal, each Marvel shareholder will receive $30 in cash and 0.7452 shares of Disney per Marvel share, together worth $50 - or a 29 premium over Marvel's stock price at that point in time.

Collateralized Debt Obligations (CDO) played a key role in the growth of Asset-Backed Security (ABS) issuance between 2004 and 2007 by providing a mechanism for lower-rated ABS to be used as collateral for the creation of AAA securities. Using a database published by Pershing Square Capital Management covering all of the assets underlying 528 CDOs and CDO-Squareds issued from 2005 through 2007 and using rating history and other information from the ABSNet database, we compare the characteristics and performance of ABS observed in a CDO with other ABS not observed in a CDO.

This paper studies the presence of hedge funds in the Chapter 11 process and their effects on bankruptcy outcomes. Hedge funds strategically choose positions in the capital structure where their actions could have a bigger impact on value. Their presence, especially as unsecured creditors, helps balance power between the debtor and secured creditors.

We consider the optimal design of mortgage-backed securities (MBS) in a dynamic setting in which a mortgage underwriter with limited liability can engage in costly hidden effort to screen borrowers and can sell loans to investors. We show that (i) the timing of payments to the underwriter is the key incentive mechanism, (ii) the maturity of the optimal contract can be short, and that (iii) bundling mortgages is efficient as it allows investors to learn about underwriter effort more quickly, an information enhancement effect.

I investigate the contribution of pharmaceutical innovation to recent longevity growth in Germany and France. First, I examine the effect of the vintage of prescription drugs (and other variables) on the life expectancy and age-adjusted mortality rates of residents of Germany, using longitudinal, annual, state-level data during the period 2001–2007. The estimates imply that about one-third of the 1.4-year increase in German life expectancy during the period 2001–2007 was due to the replacement of older drugs by newer drugs.

Based on a sample of highly leveraged Austrian ski hotels undergoing debt restructurings, we show that reducing a debt overhang leads to a significant improvement in operating performance. Changes in leverage in the debt restructurings are instrumented with Unexpected Snow, which captures the extent to which a ski hotel experienced unusually good or bad snow conditions prior to the debt restructuring.
