Die Inflation ist derzeit das beherrschende makroökonomische Problem in China. Seit einigen Monaten werden Preissteigerungsraten von mehr als sechs Prozent verzeichnet. Restriktive wirtschaftspolitische Maßnahmen sind bisher weitgehend wirkungslos geblieben. Die Regierung hat inzwischen...

In this paper we analyse household holdings of the monetary aggregate M3 in the euro area from 1991 until 2009. We develop a nominal model with satisfactory economic and statistical properties. The main determinants are a transactions variable, wealth considerations, opportunity costs and...

I apply the Johansen and Swensen (1999, 2004) method of testing exact rational expectations within the cointegrated VAR (Vector Auto-Regressive) model, to testing the New Keynesian (NK) model. This method permits the testing of rational expectation systems, while allowing for non-stationary...

A transactions model of the demand for multiple media of exchange is developed. Some results are expected, and others are both new and surprising. There are both extensive and intensive margins to currency substitution, and inflation may affect the two margins differently, leading to subtle...

This paper presents a theoretical framework that allows a taxonomy of hyperinflation, namely: (i) bubble, (ii) weak and (iii) strong hyperinflation. The inflation tax revenue curve is used to characterize each type of hyperinflation and we use this curve to test them. The bubble and strong...
