Barriers to depository uses of derivatives: an empirical analysis

We examine the relationship between derivatives use of US savings associations during 1993–1997. The advantage of examining thrifts is that they are only end-users of derivatives. We find that: (1) firm size positively correlated with derivatives use generally and to OTC derivatives use in particular; (2) the dominant underlying reason for the effect of firm size upon derivatives usage appears to be transactions cost, not the cost of acquiring the expertise to manage portfolio interest rate risk; and (3) the use of derivatives, especially OTC derivatives, is a least cost method of controlling interest rate risk. The lack of usage by smaller institutions, while consistent with profit-maximization, suggests that a significant segment of the industry is limited in its ability to manage interest rate risk.     

Do real interest rates converge? Evidence from the European union

We test for real interest rate convergence in the EU25 area. Our contribution is twofold: first, we account for the previously overlooked effects of structural breaks on real interest rate differentials. Second, we test for convergence against the EMU average. For the majority of our sample countries we obtain evidence of convergence towards the latter. This, however, is a gradual process subject to structural breaks, typically falling close to the launch of the euro. Our findings have important implications relating to the single monetary policy and the progress new EU members have achieved towards joining the euro.     

Corporate derivatives use and the cost of equity

We investigate the relation between derivatives use and corporations’ cost of equity capital. Using a large sample of non-financial firms, we compute and analyze (i) the relative cost of equity of firms that use derivatives and those that do not; and (ii) the change in cost of equity experienced by firms initiating derivatives programs. We find that the cost of equity of derivatives users is lower than non-users by 24-78 basis points. Our results are robust to specifications that account for potential endogeneity related to a firm’s derivatives use and capital structure decisions. We further find that the reduction in the cost of equity is attributable to both lower market beta and SMB beta, suggesting that firms use derivatives to reduce their financial distress risk and that this distress risk has a systematic component that is priced in the market. Finally, the observed reductions in the cost of equity tend to be largest for smaller firms and for firms utilizing currency and interest rate derivatives.     

On the calibration of local jump-diffusion asset price models

We consider the inverse problem of calibrating a localized jump-diffusion process to given option price data. It is shown that applying Tikhonov regularization to the originally ill-posed problem yields a well-posed optimization problem. For the solution of the latter, i.e., the calibrated (infinite-dimensional) parameter of the process, we prove the stability and furthermore obtain convergence results. The work-horse for these proofs is the forward partial integro-differential equation associated to the European call price. Moreover, by providing a precise link between the parameters and the corresponding asset price models, we are able to carry over the stability and convergence results to the associated asset price models and hence to the model prices of exotic derivatives. Finally we indicate some possible applications.     

Derivatives, Portfolio Composition, and Bank Holding Company Interest Rate Risk Exposure

This article examines the role played by derivatives in determining the interest rate sensitivity of bank holding companies' (BHCs) common stock, controlling for the influence of on-balance sheet activities and other bank-specific characteristics. The major result of the analysis suggests that derivatives have played a significant role in shaping banks' interest rate risk exposures in recent years. For the typical bank holding company in the sample, increases in the use of interest rate derivatives corresponded to greater interest rate risk exposure during the 1991–1994 period. This relationship is particularly strong for bank holding companies that serve as derivatives dealers and for smaller, end-user BHCs. During earlier years, however, there is no significant relationship between the extent of derivatives activities and interest rate risk exposure. There are two plausible interpretations of the relationship between interest rate derivative activity and interest rate risk exposure in the latter part of the sample period: one interpretation suggests that derivatives tend to enhance interest rate risk exposure for the typical BHC in the sample, while the other suggests that derivatives may be used to partially offset high interest rate risk exposures arising from other activities. The analysis provides support for the first of these two interpretations.     

The economic determinants of interest rate option smiles

We address three questions relating to the interest rate options market: What is the shape of the smile? What are the economic determinants of the shape of the smile? Do these determinants have predictive power for the future shape of the smile and vice versa? We investigate these issues using daily bid and ask prices of euro (€) interest rate caps/floors. We find a clear smile pattern in interest rate options. The shape of the smile varies over time and is affected in a dynamic manner by yield curve variables and the future uncertainty in the interest rate markets; it also has information about future aggregate default risk. Our findings are useful for the pricing, hedging and risk management of these derivatives.     

Board Composition And Corporate Use Of Interest Rate Derivatives

We provide new evidence on the motives for corporate hedging by examining the relation between the quality of the firms' monitoring mechanisms and the quantity of interest rate derivatives employed. Because the capital structure decision and hedging decision are considered to be endogenous, the firm's capital structure and level of interest rate derivative use are modeled simultaneously. We show a positive relation between the relative influence of outside directors and the quantity of derivatives used. This evidence indicates that outside directors take an active role in derivatives usage and that firms employ hedging in the shareholders' best interests.     

Design and Estimation of Quadratic Term Structure Models

We consider the design and estimation of quadratic term structuremodels. We start with a list of stylized facts on interest ratesand interest rate derivatives, classified into three layers: (1)general statistical properties, (2) forecasting relations, and (3)conditional dynamics. We then investigate the implications of eachlayer of property on model design and strive to establish amapping between evidence and model structures. We calibrate atwo-factor model that approximates these three layers ofproperties well, and show that a flexible specification for themarket price of risk is important in capturing the stylizedevidence in forecasting relations while factor interactions areindispensable in generating the hump-shaped dynamics of bondyields.
