This paper characterizes the frequency domain properties of feedback control rules in linear systems in order to better understand how different policies affect outcomes frequency by frequency. We are especially concerned in understanding how reductions of variance at some frequencies induce...

The so-called P* model is frequently used or referred to in discussions of monetary targeting. This gives the impression that the P* model might provide some rationale for monetary targeting or for the monetary reference value used by the Eurosystem. The P* model implies that inflation is...

The recent consensus view, that the gold standard was the leading cause of the worldwide Great Depression 1929-33, stems from two propositions: (1) Under the gold standard, deflationary shocks were transmitted between countries and, (2) for most countries, continued adherence to gold prevented...

This paper defines an efficient rule for monetary policy as one that minimizes a weighted sum of output variance and inflation variance. It derives several results about the efficiency of alternative rules in a simple macroeconomic model. First, efficient rules can be expressed as 'Taylor rules'...
