Este artículo trata sobre la inversión en mercados de opciones y desarrolla un procedimiento inferencial Bayesiano para evaluar el precio de opciones europeas que permite combinar formalmente la información de las series históricas de precios del subyacente y opciones con las expectativas...

This study analyzes the elasticities of demand and income from electricity for domestic and industrial use, for Colombia (2000-2011), by estimating demand equations by OLS. The impacts on macroeconomic variables, which generate changes in the price of electricity, are also estimated by using a...

The propose of this paper is to develop a Bayesian procedure that adequately account for studies with zero observations in meta-analysis and then we focus the problem in the context of the Bayesian selection models. Also, attention is focused to the link distribution between effectiveness in...

This paper aims to analyse the underlying factors of varied behaviour shown in the store set of purchase of households during a time period (temporal variation). In order to examine whether there are differences between households with and without shopping varied behaviour, a Bayesian Separate...

This paper develops a dynamic stochastic general equilibrium model, which is calibrated for the Peruvian economy and can be useful for the design and analysis of monetary policy. The model includes a second currency that replaces partially the domestic currency in its functions of unit of...

This paper evaluates from a microeconomic perspective the lending cost determinants in the Peruvian banking system in the June 2004-December 2005 period. The evaluation considers the credit market segments identified in a prior study (published in 2002). Furthermore, it reviews the progress...

The Black-Litterman (BL) model has been proposed as an alternative to Markowitz's average-variance model for the structuring of financial asset portfolios, allowing the incorporation of perspectives of fundamental analysts and guaranteeing a high degree of diversification. This model is applied...

En este estudio se identifica un conjunto de características asociadas al hecho de que un migrante colombiano retornado se convierta en un emprendedor. El análisis se realizó con los datos recogidos en la encuesta Global Entrepreneurship Monitor (GEM) cuyo formulario fue modificado en el año...

The approximation of G/G/s models from Markov models M/M/s has been studied in the literature. The study of a queue model is detailed in the present article, using times of arrivals and time service distributed by Weibull whose estimation of parameters was performed with the Bayesian method...

The valuation of options and to a large extent the financial derivatives market require an optimal estimation of the volatility, since this is precisely the variable that is negotiated. We present then a statistical methodology for the estimation of the volatility parameter for an asset using...
