Determining the Optimal Selling Time of Cattle: A Stochastic Dynamic Programming Approach
(Universidad EAFIT, 2015-07-09)
The world meat market demands competitiveness and optimal livestock replacement decisions can help to achieve this goal. We introduce a novel discrete stochastic dynamic programming framework to support a manager’s ...
Welfare gains of the poor: An endogenous Bayesian approach with spatial random effects
(Universidad EAFIT, 2015-07-07)
We introduce a Bayesian instrumental variable procedure with spatial random effects that handles endogeneity, and spatial dependence with unobserved heterogeneity. We find through a limited Monte Carlo experiment that our ...
Análisis sobre elección de ocupaciones que generen empleo usando modelos de elección discreta: Medellín Área Metropolitana 2009
The formation and consolidation of businesses is a key element in achieving social and economic transformation of Colombia. Example of this hipotesis, are the increasing number of academic papers and policies to ...
Un sistema casi ideal de demanda para el gasto en Colombia: una estimación utilizando el método generalizado de los momentos en el periodo 1968-2007
This work uses a Linear Approximation of the Almost Ideal Demand System (LA/AIDS) to examine Colombian's expenditure in daily needs and to estimate the respective expenditure and price elasticities using Colombian ...

A Multi-Stage Almost Ideal Demand System: the case of beef demand in Colombia
The main objective in this paper is to obtain reliable long-term and short-term elasticities estimates of the beef demand in Colombia using quarterly data since 1998 until 2007. However, complexity on the decision process ...
An ordered categorical response model with endogenous switching: Simulation Exercises and an Application to State Health
We develop and estimate a full information maximum likelihood ordered categorical response model with endogenous switching. Simulation exercises show that estimated parameters are unbias and consistent. And application to ...
