IMPORTANCIA DE LAS RIGIDECES NOMINALES Y REALES EN COLOMBIA: UN ENFOQUE DE EQUILIBRIO GENERAL DINáMICO Y ESTOCáSTICO*

the aim of this research paper is to establish what the combination of nominal and real rigidities for inclusion in a dynamic stochastic general equilibrium (dsge) model should be so that it may replicate the dynamic of added variables in the colombian economy. towards this end, several dsge models have been calculated using diverse combinations of nominal and real rigidities with bayesian methods. the results indicate that the empirical adjustment of the model is determined by, in order of importance, rigidity in salaries, rigidity in domestic prices, adjustment costs in investment, type of indexing used, and rigidity of import prices. in so far as the short term model dynamic is concerned, sensitivity to monetary policy shock depends upon, to a greater degree, salary rigidity, type of price indexing, and adjustment costs in investment
