A fast and accurate method for pricing early exercise and certain exotic options in computational finance is presented. The method is based on a quadrature technique and relies heavily on Fourier transformations. The main idea is to reformulate the well-known risk-neutral valuation formula by...

In this paper we recover the Black-Scholes and local volatility pricing engines in the presence of an unspecified, fully stochastic volatility. The input volatility functions are allowed to fluctuate randomly and to depend on time to expiration in a systematic way, bringing the underlying theory...

For deals denominated in a single currency, different collateralization schemes imply different accrual rates for funds posted as collateral, so that we can end up with different current accounts that accrue at different rates and their corresponding discount factors. In this paper we examine...

Any demand equation satisfying Lau’s (1982) Fundamental Theorem of Exact Aggregation and is 0 homogeneous in prices and income will have a Gorman (1981) functional form for each income term. This property does not depend on symmetry or adding up. The implications of this result are...

In this paper, money demand models using narrowly- and broadly-defined monetary aggregates have been tried to be constructed for the Turkish economy. Using some contemporaneous co-integration estimation techniques for the 1987-2007 period with quarterly data, our findings indicate that for the...

This paper provides a simple proof of the result that if a production function is homogeneous, displays non-increasing returns to scale, is increasing and quasiconcave, then it is concave. If the function is strictly quasiconcave or one-to-one, homogeneous, displays decreasing returns to scale...

In this paper we will study the influence of qualitative variables on the unit root tests for stationarity. For the linear regressions involved the implied assumption is that they are not influenced by such qualitative variables. For this reason, after we have introduced such variables, we...

The Black Scholes Model (BSM) is one of the most important concepts in modern financial theory both in terms of approach and applicability. The BSM is considered the standard model for valuing options; a model of price variation over time of financial instruments such as stocks that can, among...

Options are historically being priced using Black Scholes option pricing model and one of the prominent features of it is normal distribution. In this research paper I will calculate European call options using log logistic distribution instead of normal distribution. My argument is that a model...

This paper derives efficient pricing formulae for renewable energy Feed-in Tariff (FiT) designs that incorporate exposure to uncertain market prices by using option pricing theory. Such FiT designs are presented as a means to delineate market price risk amongst investors and policymakers when...
