Knowledge that Transforms

[We develop a tractable model of realization utility that studies the role of reference-dependent S-shaped preferences in a dynamic investment setting with reinvestment. Our model generates both voluntarily realized gains and losses. It makes specific predictions about the volume of gains and losses, the holding periods, and the sizes of both realized and paper gains and losses that can be calibrated to a variety of statistics, including Odean's measure of the disposition effect. Our model also predicts several anomalies, including, among others, the flattening of the capital market line and a negative price for idiosyncratic risk.]

[Does the ability of suppliers of corporate debt capital to hedge risk through credit default swap (CDS) contracts impact firms' capital structures? We find that firms with traded CDS contracts on their debt are able to maintain higher leverage ratios and longer debt maturities. This is especially true during periods in which credit constraints become binding, as would be expected if the ability to hedge helps alleviate frictions on the supply side of credit markets.]

[How do individuals decide to become entrepreneurs and learn to make optimal entrepreneurial decisions? The concentration of entrepreneurs in regions such as Silicon Valley has stimulated research and policy interest into the influence of peers, but the causal effect is hard to identify empirically. We exploit the exogenous assignment of students into business-school sections to identify the causal effect of entrepreneurial peers. We show that, in contrast to prior findings, a higher share of entrepreneurial peers decreases, rather than increases, entrepreneurship. The decrease is driven by a reduction in unsuccessful entrepreneurial ventures; the effect on successful ventures is significantly more positive.]

[We analyze the efficiency of indexing executive pay by calibrating the standard compensation model to a large sample of U.S. CEOs. The benefits from indexing the strike price of options are small, and fully indexing all options would increase compensation costs by 50% for most firms. Indexing has several effects with overall ambiguous outcome; the quantitatively most important effect is to reduce incentives, because indexed options pay off when CEOs' marginal utility is low. The results also hold if CEOs can extract rents and extend to the case of indexing shares. Our findings may justify the common practice of "pay-for-luck."]

[We analyze auctions for the settlement of credit default swaps (CDS) theoretically and evaluate them empirically. The requirement to settle in cash with an option to settle physically leads to an unusual two-stage process. In the first stage, participants affect the amount of the bonds to be auctioned off in the second stage. Participants in the second stage may hold positions in derivatives on the assets being auctioned. We show that the final auction price might be either above or below the fair bond price because of strategic bidding on the part of participants holding CDS. Empirically, we observe both types of outcomes, with undervaluation occurring in most cases. We find that auctions undervalue bonds by an average of 6% on the auction day. Undervaluation is related positively to the amount of bonds exchanged in the second stage of the auction, as predicted by the theory. We suggest modifications of the settlement procedure to minimize the underpricing.]

[This paper assesses the impact of the geographic diversification of bank holding company (BHC) assets across the United States on their market valuations. Using two new identification strategies based on the dynamic process of interstate bank deregulation, we find that exogenous increases in geographic diversity reduced BHC valuations. We also find that the geographic diversification of BHC assets increased insider lending and reduced loan quality. Taken together, these findings are consistent with theories predicting that geographic diversity intensifies agency problems.]

[A central issue in finance is whether stock prices move because of revisions in expected cash flows or discount rates, and by how much of each. Using direct cash flow forecasts, we show that stock returns have a significant cash flow news component whose importance increases with the investment horizon. For horizons over two years, cash flow news is more important. These conclusions hold at both the firm and aggregate levels, and diversification plays a secondary role in affecting the relative importance of cash flow and discount rate news. Our findings highlight the importance of cash flows in asset pricing.]

[In this paper, we use call option prices to identify synergies and news from merger and acquisition (M&A) transaction announcements. We find that M&A announcements result in large and approximately equal gains to the bidder and the target on average, with the combined gains being large enough to justify the premium paid to target shareholders. On average, M&A announcements release good news about targets, but bad news about bidders. This suggests that market prices understate true synergy gains, and helps reconcile the generally negative market-based evidence on value-creation in takeovers with their continued prominence in everyday business strategy.]

[Using a unique panel data set from a U.K. credit card company, we analyze the interest rate sensitivity of subprime credit card borrowers. In addition to all individual transactions and loan terms, we have access to details of a randomized interest rate experiment conducted by the lender on existing (inframarginal) loans. For the whole sample, we estimate a statistically significant £3.4 reduction in monthly credit demand in response to a five percentage point increase in interest rates. This aggregate response is small, but it masks very interesting heterogeneity in the sample. We find that only low-risk borrowers who fully utilize their credit cards lower their credit demand significantly when faced with an increase in interest rates. We also document that a five percentage point increase in interest rates generates significant additional revenue for the lender without inducing delinquency over a short horizon.]

[We formulate a model of utility for a continuous-time framework that captures aversion to ambiguity about both volatility and drift. Corresponding extensions of some basic results in asset pricing theory are presented. First, we derive arbitrage-free pricing rules based on hedging arguments. Because ambiguous volatility implies market incompleteness, hedging arguments determine prices only up to intervals. In order to obtain sharper predictions, we apply the model of utility to a representative agent endowment economy and study equilibrium asset returns. A version of the consumption capital asset pricing model is derived, and the effects of ambiguous volatility are described.]
