For a proper assessment of risks associated with the trading of derivatives, the performance of hedging strategies should be evaluated not only in the context of the idealized model that has served as the basis of strategy development, but also in the context of other models. In this paper we consider the class of so-called interval models as a possible testing ground. In the context of such mo...

Many hypotheses have been proposed to explain multiple mating in females. One of them is bet hedging, that is avoiding having no or very few offspring in any given generation, rather than maximizing the expected number of offspring. However, within-generation bet hedging is generally believed to be an unimportant evolutionary force, except in very small populations. In this study, we derive pre...

A progressive hedging method incorporated with self-concordant barrier functions has been developed by Zhao [23] for solving multistage stochastic programs. The method relaxes the nonanticipativity constraints by the Lagrangian dual approach and smooths the Lagrangian dual function by self-concordant barrier functions. This paper discusses in detail the implementation of this method and reports...

This paper investigates the impact of hedging activities on U.S. export pricing. A theoretical framework of export pricing model with a hedging component was derived to test the hypothesis via exchange rate pass-through. The hypothesis is that a firm with a high (low) hedging engagement would have a low (normal) degree of exchange rate pass-through, ceteris paribus. Two measurements of the hedg...

Effective hedging strategies for variable annuities are crucial for insurance companies in preventing potentially large losses. We consider discrete hedging of options embedded in guarantees with ratchet features, under both equity (including jump) risk and interest rate risk. Since discrete hedging and the underlying model considered lead to an incomplete market, we compute hedging strategies ...

Managers can improve real risk-adjusted firm performance by matching nominal assets with nominal liabilities, thereby reducing the sensitivity of real risk-adjusted returns to unexpected inflation. We model these returns as a function of nominal and real assets and liabilities and illustrate our proposition using a simulation. We test the empirical implications of our model in a sample of liste...

This paper compares the pricing and hedging performance of the LMM model against two spot-rate models, namely Hull-White and Black-Karasinski, and the more recent Swap Market Model from an Asset-Liability-Management (ALM) perspective. In contrast to previous studies in the literature, our emphasis here is on ALM and we use hedging performance on Bermudan swaptions to proxy risk management outco...

We examine the impact of corporate currency hedging on economic stability by introducing hedging activity in a Mundell-Fleming-Tobin framework for analyzing currency and financial crises. The ratio between hedged and unhedged firms is modelled depending on firm size as well as hedging costs. The results indicate that, with an increasing fraction of hedged firms in an economy, the magnitude of a...

This paper uses a principal-agent model to study the interaction between hedging and earnings management. Hedging makes earnings management more difficult and they appear to be strategic substitutes in this model, which is both consistent with existing empirical evidence and provides a new explanation for that evidence. If hedging decision is contractible, hedging is efficient since it reduces ...
