Sinopsis de la obra en idioma inglés.

This paper shows the use of three methodological focuses to build short term situations. The techniques are applied to the information from four Latin American countries. In the case of Panama, there is an exercise that leads to a short term macroeconometric model, unique in Latin American in the last decade. For the date from Guatemala, a conceptually reduced model is used which, aiming at the foreign debt problem, stresses its validity for this decade. The data from Mexico and Costa Rica are handled with modern techniques of time series analysis. For Mexico, the data has been assessed under the cyclical concepts of dating the time series, hence susceptible of comparative analysis. [ABSTRACT FROM AUTHOR]
