Forward rate dynamics are modeled as a random field. In contrast to multifactor models, random field models offer a parsimonious description of term structure dynamics, while eliminating the self-inconsistent practice of recalibration. The form of the drift of the instantaneous forward rate process necessary to preclude arbitrage under the risk-neutral measure is obtained. Forward risk-adjusted measures are identified and used to price a bond option when the forward volatility structure depends on the square root of the current spot rate. Several classes of tractable random field models are presented.

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.

This study examines the behavior of spreads paid in firm underwritten seasoned common stock offerings and straight bond offerings. Estimates indicate that up to 85% of the spread is variable cost and that the marginal spread is rising. Further, offerings that are likely to require greater underwriting services encounter higher marginal spreads. These findings are consistent with there being a family of U-shaped spreads, with lower quality offerings priced on higher spreads, unlike the economies of scale view of spreads. They agree with the views that underwriters provide valuable services and that the marginal cost of external finance is rising.

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.
