What is the optimum quantity of money in a society? This paper answers this question both from the perspective of a utility maximizing model with real balances in the utility function, and employing an inventory theoretic model which focuses attention on the costs of transacting in different...

In recent macroeconomic theory, relative price variability (RPV) generates the central distortions of inflation. This paper provides first evidence on the empirical relation between inflation and RPV in the euro area focusing on threshold effects of inflation. We find that expected inflation...

Recent research on the unobserved economy suggests that the phenomenon has important implications for both macroeconomic policy and public finance. Attention is focused on the public finance implications by developing a simple macro model from which it is possible to derive a Laffer curve. The...

The size, growth and causes of the US “underground economy” are examined in light of new estimates of foreign holdings of US currency. World dollarization partially resolves the “currency enigma” which refers to the anomaly that roughly 80% of the US currency supply is “missing” and...

The paper derives the monetary policy reaction function implied by money growth targeting. It consists of an interest rate response to deviations of the inflation rate from target, to the change in the output gap, to money demand shocks and to the lagged interest rate. In the second part, it is...

This paper investigates how the dynamic adjustment of the European overnight rate Eonia to the term spread and the ECB's policy rate has been affected by rate expectations and the operational framework of the ECB. In line with recent evidence found for the US and Japan, the reaction of the Eonia...

Papers estimating the reaction function of the Bundesbank generally find that its monetary policy from the 1970s to 1998 can well be captured by a standard Taylor rule according to which the central bank responds to the output gap and to deviations of inflation from target, but not to monetary...

The paper analyses the performance of simple interest rate rules which feature a response to noisy observations of inflation, output and money growth. The analysis is based on a small empirical model of the hybrid New Keynesian type which has been estimated on euro area data by Stracca (2007)....

The Eurosystem's main refinancing operations (MRO) are key for the interbank money market and the monetary transmission process in the euro area. This paper investigates how money market rates respond to the information revealed by various aspects of an MRO auction outcome. Our results confirm...
