Econometría dinámica: una aplicación a la demanda de billetes y monedas en poder del público

Abstract

Although economic theory cannot say very much about lag structures, data analysis can be helpful. This work describes the econometric approach which starts from a general or an unrestricted form and search for simplifications appropriate to the data in order to obtain the dynamic specification of the model. Preliminary results of its application to the demand for currency (Argentina 1970-1986, on quarterly basis) are reported.
