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...

In this paper I present a real-time estimation of the evolution of the Investment, constructed from a broad set of high frequency economic indicators: known in the literature as Nowcasting. The Nowcast exercise was developed considering three groups of monthly indicators throughout dynamic...

En este trabajo se estudia el comportamiento de los retornos delos tres principales índices bursátiles de Colombia: el IBB de la Bolsa de Bogotá, el IBOMED de la Bolsa de Medellín, y el IGBC de Bolsa de Valores deColombia. A través de un modelo STAR GARCH se identifican dos estados...

We present a new heteroskedastic conditional variance model using NonLinear Moving Average as the basis for this specification [NLMACH(q)]. The typical problem of this class of models-i.e., noninvertibility—is solved by means of an intuitive parametric restriction; this allows us to use...
