Monetary Policy with Liquidity Frictions

This paper explores the welfare effects of a reduction in the inflation rates in an environment of incomplete markets. We built a dynamic heterogeneous agent model that features idiosyncratic risks in the labor supply and liquidity frictions. The model shows that a disinflation policy results in an income reallocation among debtors and lenders. The changes in the capital returns conveys variations in the precautionary savings and hence, an intertemporal redistribution of wealth and income. The welfare implications are develop according to the incomplete market features and the money plays a role of smoothing consumption when the agents faces income variability without state contingent insurance. The model is calibrated for the Colombian economy in such a way that disinflation episodes are replicated. Early results show that the disinflation monetary policy leads to improvements of liquidity in the economy because the money holdings are used by the agents for wealth transfer over time. This paper shows quantitative evidence in which disinflation facts are associated with increments in the average real money holdings and average consumption. In addition, the volatility of consumption is reduced as the inflation rate falls, while the volatility of money holdings increases (i.e. precautionary demand for money balance).
