Gram-Charlier expansion have become popular in Finance as a generalization over the normality assumption. Even though Gram-Charlier expansions allow for a certain flexibility over skewness and kurtosis they have the unfortunate drawback of sometimes yielding negative densities. The goal of this...

The Market Models of the term structure of interest rates, in which forward LIBOR or forward swap rates are modelled to be lognormal under the forward probability measure of the corresponding maturity, are extended to a multicurrency setting. If lognormal dynamics are assumed for forward LIBOR...

This paper attempts to uncover the determinants of the dealer bid-ask spread in the foreign exchange market. Prior research has examined the Huang–Masulis model wherein the spread is modelled as a function of dealer competition and volatility. We first extend this model to a much larger...

The purpose of this paper is to provide a new set of tools for policy makers at central banks. Based on the Garman-Kohlhagen formula for currency options, this research extends it with the Taylor-rule expression used for inflation targeting, thus obtaining the corresponding Call and Put options...

This is the first study that employs option pricing model to measure the position-unwinding risk of currency carry trade portfolios, which covers moment information as the proxy for crash risk. We show that high interest-rate currencies are exposed to higher position-unwinding risk than low...

Forward exchange rate bias explanation generally falls into two categories – assumption of rational expectation resulting in a risk premium and expectation errors which is systematic. The paper tests the bias in the Indian forward exchange markets using one-month and three month forward...

Any security’s expected return can be decomposed into its “carry” and its expected price appreciation, where carry is a model-free characteristic that can be observed in advance. While carry has been studied almost exclusively for currencies, we find that carry predicts returns both in the...

We investigate the predictive information content in foreign exchange volatility risk premia for exchange rate returns. The volatility risk premium is the difference between realized volatility and a model-free measure of expected volatility that is derived from currency options, and reflects...

The two most intriguing anomalies in currency markets are: 1) the implied volatility smile in currency options, and 2) the forward discount bias in currency exchange rates. I show that if currency options are valued in analogy with the underlying currency and beliefs are heterogeneous, then the...
