Abstract

This paper analyses the behaviour of the economy of Puerto Rico through a vector autorregresive and cointegration model. The obtained results point out that the economy of Puerto Rico has the general behaviour of an IS-LM model with market imperfections, which means that, for the economy of Puerto Rico, the rate of interest, the price index, the real production and the money supply of the United States maintain a long-run equilibrium relation. These variables could be used like a strategic axle for the construction of any macroeconometric model.
