The stability of german money demand: Not just a myth

The stability of German money demand has been analyzed in a series of papers in recent years, especially since unification. In this paper the critical question of stability is reviewed, using various estimation techniques and testing procedures for long-run stability. To take financial innovations into account, the opportunity cost measure is calculated by differentiating between traditional savings deposits and special savings facilities, which are a major form of financial innovation in Germany. Overall, there are strong indications of a stable long-run money-demand relationship.

Reconsidering the Role of Monetary Indicators for Euro Area Inflation from a Bayesian Perspective Using Group Inclusion Probabilities

This paper addresses the relative importance of monetary indicators for forecasting inflation in the euro area in a Bayesian framework. Bayesian Model Averaging (BMA)based on predictive likelihoods provides a framework that allows for the estimation of inclusion probabilities of a particular variable, that is the probability of that variable being in the forecast model. A novel aspect of the paper is the discussion of group-wise inclusion probabilities, which helps to address the empirical question whether the group of monetary variables is relevant for forecasting euro area inflation. In our application, we consider about thirty monetary and non-monetary indicators for inflation. Using this data, BMA provides inclusion probabilities and weights for Bayesian forecast combination. The empirical results for euro area data show that monetary aggregates and non-monetary indicators together play an important role for forecasting inflation, whereas the isolated information content of both groups is limited. Forecast combination can only partly outperform single-indicator benchmark models.

Household's Portfolio Structure in Germany - Analysis of Financial Accounts Data 1959-2009

Based on a Financial Almost Ideal Demand System (FAIDS), this paper investigates the wealth structure of German households. The long-run wealth elasticities and interestrate elasticities were calculated using a unique new quarterly financial accounts macrodata set which covers the period from 1959 to 2009 and contains a portfolio of eight different financial assets. Descriptive analysis shows that all financial assets were characterized by substantial volatility of their weight in the portfolio of households. We found that portfolio shifts in the long run are determined significantly by changes in interest rates. The estimated model provides evidence that currency (and transferable deposits) is mainly a substitute for other assets and time deposits are typically a complement. Wealth elasticity is for most assets around unity. JEL Classification: E21, G11, C32
