Knowledge that Transforms

There is a global trend in initial public offerings toward the increased use of book building. Relative to other methods such as auctions, a key feature of book building is that the underwriter has total discretion in allocating shares, allowing allocations to be based on long-term relationships between underwriters and investors. In a multiperiod model with endogenous (and costly) information acquisition. I show that the underwriter's ability to lower underpricing depends largely on its ability to favor regular uninformed investors. One implication is that the hybrid book building/open offer method, which is becoming increasingly popular internationally, will lead to higher underpricing than straight book building.

Opening mechanisms play a crucial role in information aggregation following the overnight nontrading period. This article examines the process of price discovery at the New York Stock Exchange single-price opening auction. We develop a theoretical model to explain the determinants of the opening price and test the model using order-level data. We show that the presence of designated dealers facilitates price discovery relative to a fully automated call auction market. This is consistent with specialists extracting information from observing the evolution of the limit order book. In addition, the specialist's opening trade reflects noninformational factors such as price stabilization requirements.

This article discusses the effects of credit market competition on a bank's incentive to keep its commitment to lend to a borrower when the borrower's credit quality deteriorates. It is shown that, unlike in the borrower's commitment problem to keep borrowing from the same bank in "good" times, the increased competition may strengthen a bank's incentive to keep its commitment. Banks offer loans with commitment to the highest quality borrowers but, when faced with competition from bond markets, they also give these loans to lower quality borrowers. An increase in the number of banks has a non-monotonic effect; new banks reinforce a bank's incentive only if there are a small number of banks.

This article develops a general equilibrium, continuous time model where portfolio constraints generate mispricing between redundant securities. Constrained consumption-portfolio optimization techniques are adapted to incorporate redundant, possibly mispriced securities. Under logarithmic preferences, we provide explicit conditions for mispricing and closed-form expressions for all economic quantities. Existence of an equilibrium where mispricing occurs with positive probability is verified in a specific case. In a more general setting, we demonstrate the necessity of mispricing for equilibrium when agents are heterogeneous enough. The construction of a representative agent with stochastic weights allows us to characterize prices and allocations, given mispricing occurs.

We examine how certain firm- and market-specific characteristics affect incumbent firms' responses to new entry into their local markets. Data comes from the discount department store industry where Wal-Mart entered a large number of markets in a short period of time. Consistent with existing research, larger and more profitable incumbents respond more aggressively to Wal-Mart's entry, while more highly levered incumbents respond less aggressively. Also, there is evidence that incumbent managers fight harder (possibly overinvest) when their job is at greater risk and high managerial ownership appears to reduce this agency problem. Incumbent firms behave differently in markets under attack by Wal-Mart than in markets not yet threatened, suggesting that some of the documented responses are specific to Wal-Mart's entry.

This article empirically analyzes some properties shared by all one-dimensional diffusion option models. Using S&P 500 options, we find that sampled intraday (or interday) call (put) prices often go down (up) even as the underlying price goes up, and call and put prices often increase, or decrease, together. Our results are valid after controlling for time decay and market microstructure effects. Therefore one-dimensional diffusion option models cannot be completely consistent with observed option price dynamics; options are not redundant securities, nor ideal hedging instruments—puts and the underlying asset prices may go down together.

When a risk factor is missing from an asset pricing model, the resulting mispricing is embedded within the residual covariance matrix. Exploiting this phenomenon leads to expected return estimates that are more stable and precise than estimates delivered by standard methods. Portfolio selection can also be improved. At an extreme, optimal portfolio weights are proportional to expected returns when no factors are observable. We find that such portfolios perform well in simulations and in out-of-sample comparisons.

This article develops a model for evaluating alternative hedging strategies for financially constrained firms. A key advantage of the model is the ability to capture the intertemporal effects of hedging on the firm's financial situation. We characterize the optimal hedge. A wide range of alternative hedging strategies can be specified and the model allows us to determine in each case if the hedging strategy raises or lowers firms value and by how much. We show that hedging firm value, hedging cash flow from operations and hedging sales revenue are not optimal. The article highlights the fact that every hedging strategy comes packaged with a borrowing strategy which requires careful consideration.

This study compares the market value of firms that reorganize in bankruptcy with estimates of value based on management's published cash flow projections. We estimate firm values using models that have been shown in other contexts to generate relatively precise estimates of value. We find that these methods generally yield unbiased estimates of value, but the dispersion of valuation errors is very wide - the sample ratio of estimated value to market value varies from less than 20% to greater than 250%. Cross-sectional analysis indicates that the variation in these errors is related to empirical proxies for claimholders' incentives to overstate or understate the firm's value.
