The main result of this paper consists in the resolution of the inverse problem for the Black-Cox (1976) model, using the method proposed by Sukhomlin (2007). Based on the backward approach, we obtain an exact expression of the implied volatility expressed as a function of quantifiable market...

El principal resultado de este artículo consiste en la resolución del problema inverso del modelo de Black-Cox (1976), usando el método propuesto por Sukhomlin (2007). Se parte del enfoque retrógrado (backward) para obtener una expresión exacta de la volatilidad implícita en función de...

This article studies the Chilean Stock Market's efficiency. To corroborate efficiency, we use a partial equilibrium model for financial asset pricing. We contrast between observed and expected Chilean stock price volatility under an efficient stock market framework. For the statistical analysis,...
