Incluye bibliografía ; In this paper we propose a model for monthly inflation with stochastic trend, seasonal and transitory components with QGARCH disturbances. This model distinguishes whether the long-run or short-run components are heteroscedastic. Furthermore, the uncertainty associated...

Through the use of Structural Times Series Models we estimated: potential output, the output gap and the business cycles for the Mexican GDP (1980.1-2006.4). We found that: a) the potential output has varied sharply for two different time periods: 2.1% (1980.4-1994.4) and 3.7% (1995.4-2006.4);...
