Abstract

According to many empirical studies, one aspect that determines the foundations of economic cycles in the short and medium term is the investment of capital goods since it belongs to an aggregate demand and explains the changes in phase and scope of the productive cycle in the economy. Here we establish factors that are determinant of the private investment in El Salvador. This study was prepared based on historic economic records from the period 1958-2008 and using dynamic regression techniques of time series. The methodology implemented is the following: A univariate analysis is undertaken of each series, with the goal of adequately identifying a proper ARIMA model that corresponds and adjusts to the dynamic regression model for the private investment. The objective of this study is to contribute to the establishment to the economic policies for El Salvador and to offer orientation for the modeling of phenomena in which time series are involved.
