Estimated general equilibrium models for the evaluation of monetary policy in the US and Europe

In this paper we derive a general equilibrium model based on optimising behaviour, which also implies a data consistent framework for monetary policy analysis. Specifically, our model accounts for nominal inertia in both price and wage setting as well for habits in consumption. Using US and European data from 1970 to 1998 our parameter estimates reveal that (i) price contracts last for 8 months and 13 months in the US and Euro-area, respectively; (ii) wage contracts have a length of 7 months and 1.75 years in the US and Europe, respectively; (iii) the extent of backward-looking behaviour in price setting is statistically significant in both economies with 41% of price contracts in the US and 28% in the Euro-area set according to a simple rule-of-thumb; (iv) backward-looking wage setting is only present in Europe with 17% of contracts set in a backward-looking manner; and (v) similar habits effects are present in both European and US consumption. Finally, we simulate the effects of monetary policy by considering the impact of a 1 point increase in nominal interest rates for one quarter. Our parameter estimates imply that there is a relatively muted inflationary response to interest rate increases in Europe (price inflation falls by -0.08% in Europe and 0.11% in the US) and there is a correspondingly large output response (-0.2% in the US and -0.6% in Europe).
