Monetary Policy and Multiple Equilibria

In this paper, we characterize conditions under which interest rate feedback rules wherby the nominal interest rate is set as an increasing function of the inflation rate generate multiple equilibria. We show that these conditions depend not only on the fiscal regime (as emphasized in the fiscal theory of the price level) but also on the way in which money is assumed to enter preferences and technology. We analyze this issue in flexible and sticky price environments.MONETARY POLICY ; PRICES ; INTEREST RATE

Avoiding Liquidity Traps

Once the zero bound on nominal interest rates is taken into account, Taylor-type interest-rate feedback rules give rise to unintended self-fulfilling decelerating inflation paths and aggregate fluctuations driven by arbitrary revisions in expectations. These undesirable equilibria exhibit the essential features of liquidity traps, as monetary policy is ineffective in bringing about the government's goals regarding the stability of output and prices. This paper proposes several fiscal and monetary policies that preserve the appealing features of Taylor rules, such as local uniqueness of equilibrium near the inflation target, and at the same time rule out the deflationary expectations that can lead an economy into a liquidity trap.TAYLOR RULES; LIQUIDITY TRAPS; ZERO BOUND ON NOMINAL INTEREST RATES.

Recent reforms in Spanish housing markets: an evaluation using a DSGE model

After a long academic debate, Spain finally repealed in 2012 the deduction for home purchase. The abrogation took effect in 2013. In parallel, the VAT for the purchase of new housing was increased after a short period in which it had a reduced rate. The aim of this paper is to assess the macroeconomic effects of these two relevant housing market reforms. In order to do that, we use a dynamic stochastic general equilibrium (DSGE) model calibrated to capture the key ratios of the Spanish economy. The model includes a housing market, covering both the rental market side and the property market side and credit-constrained agents. We find that these measures drive down housing prices and have a negative impact on output and employment in the construction sector. However, in the long run, this last effect is offset by the benefits of a reduction in distortionary taxes
