Schwarz. In this paper I evaluate the predictive ability of the Akaike and Schwarz information criteria using autoregressive integrated moving average models, with sectoral data of Chilean GDP. In terms of root mean square error, and after the estimation of more than a million models, the...

We search for evidence against the hypothesis of a non-linear relationship between inflation and growth rates for 1993-2012 Peruvian data. A family of dichotomous models provide the way to model the relationship between the those two variables' cycles. Given the acceleration/de-acceleration...

We jointly parameterized the generalized autoregressive conditional het- eroskedasticity that corresponds to the behavior of the variance of three variables: (a) the core Mexican stock market index (IPC), (b) the Emerging Markets Bond Index for Mexico (EMBI) as country risk pointer and, (c) the...

Este artículo toma como base la información de la tasa de desempleo de Bogotá en el periodo 1984-2000 para analizar la estacionariedad de la serie utilizando los test de Dickey Fuller Aumentado (ADF) y el de Zivot-Andrews (ZA). Se expone cómo en presencia de cambio estructural el test...

El modelo gaussiano GARCH(1,1) ha sido empleado, tradicionalmente, en el estudio de la tasa de cambio; sin embargo, un número importante de estudios recientes (utilizando modelos FIGARCH e HYGARCH) ha encontrado evidencia de persistencia en su volatilidad. En este trabajo, usando una estrategia...

This paper contains the results of a non parametric multi-step ahead forecast for the monthly Colombian inflation, using Mean conditional Kernel estimation over inflation changes, with no inclusion of exogenous variables. The results are compared with those from an ARIMA and a nonlinear STAR....

En este artículo se estudia el comportamiento de la tasa de crecimiento del PIB colombiano entre 1982-2008 a partir de un modelo SETAR (Self-Exciting Threshold Autoregressive), empleando la metodología propuesta por Tsay (1989) y Tong (1990) para la detección de no linealidades relacionadas...

In the present document it is exposed in an abstract way the models of credit portfolioes CreditMetricsTM, KMV, CreditRisk+, Credit Portfolio View in such a way that they could be calibrated and implemented in financial institutions where the quality and quantity of credit information is scanty,...
