In this paper we 'update' the option implied probability of default (option iPoD) approach recently suggested in the literature. First, a numerically more stable objective function for the estimation of the risk neutral density is derived whose integrals can be solved analytically. Second, it is...

We develop a novel financial market model in which the stock markets of two countries are linked via and with the foreign exchange market. To be precise, there are domestic and foreign speculators in each of the two stock markets which rely either on linear technical or linear fundamental...

In this paper we conduct a formal testing of the possibility of chaotic dynamics in daily exchange rate variables, namely exchange rate returns, volatility and normalized exchange rates. Substantial nonlinear dependence is found in exchange rate returns, even when GARCH-type structure is...

This article assesses the communication of the European Central Bank (ECB) using Natural Language Processing (NLP) techniques. We show the evolution of discourse over time and capture the main themes of interest for the central bank that go beyond its traditional mandate of maintaining price...

Az opcióalapú modellben a sávos árfolyamú deviza megfelel egy lebegő rendszerbe li devizának és két opciónak. Az opciók kötési árfolyama a sáv széleivel egyezik meg, így az opciós modell szerint a sáv eltolása a kötési árfolyamok megváltozásán ke resztül közvetlenül...

This paper sets up an options-based model of the exchange rate in a target zone system according to which the observed exchange rate is equivalent to a floating exchange rate adjusted with the value of two options. The strike prices of the options are the limits of the band, but the two options...

We develop a novel financial market model in which the stock markets of two countries are linked via and with the foreign exchange market. To be precise, there are domestic and foreign speculators in each of the two stock markets which rely either on linear technical or linear fundamental...

This paper presents a new numerical method for pricing American call options when the volatility of the price of the underlying stock is stochastic. By exploiting a log-linear relationship of the optimal exercise boundary with respect to volatility changes, we derive an integral representation...

We model the dynamics of asset prices and associated derivatives by considerationof the dynamics of the conditional probability density process for the value of an assetat some specied time in the future. In the case where the asset is driven by Brownianmotion, an associated \master equation"...

In the existing literature on barrier options, much effort has been exerted to ensureconvergence through placing the barrier in close proximity to, or directly onto, thenodes of the tree lattice. In this paper we show that this may not be necessary toachieve accurate option price...
