Liquidity problems lie at the heart of crises on financial markets as demonstrated in this paper by detailed descriptions of the stock market crash in 1987, the LTCM-crisis in 1998 and the financial market consequences of 11 September 2001. The events also demonstrate that modern central banks,...

In a simple New Keynesian model, we derive a closed form solution for the inflation-gap persistence parameter as a function of the policy weights in the central bank’s Taylor rule. By estimating the time-varying weights that the FED attaches to inflation and the output gap, we show that the...

We combine an estimated monetary policy rule featuring time-varying trend inflation and stochastic coefficients with a medium scale New Keynesian framework calibrated on the U.S. economy. We find the impact of variations in trend inflation on the likelihood of equilibrium determinacy to be both...

We turn our attention to the role of money for determining nominal magnitudes. Using US data, we find that the aggregate “nominal output plus and stock market capitalisation” is closely related to the money stock, lending support to one of Milton Friedman’s key monetarist propositions....
