The estimation of an ordered probit model for currency reforms trying to end 31 hyperinflations and three big inflations of the 20th century shows that the introduction of an independent central bank and the adoption of a credibly fixed exchange rate are crucial for the success of a currency...

This paper provides empirical evidence in favor of the hypothesis that the secular price increase in the 16th century is mainly caused by money supply developments as the discovery of new mines in Latin America. First we review price developments for several European countries over the 16th...

We propose a novel multivariate GARCH model that incorporates realized measures for the variance matrix of returns. The key novelty is the joint formulation of a multivariate dynamic model for outer-products of returns, realized variances and realized covariances. The updating of the variance...

In this paper we investigate whether the dynamic properties of the U.S. business cycle have changed in the last fifty years. For this purpose we develop a flexible business cycle indicator that is constructed from a moderate set of macroeconomic time series. The coincident economic indicator is...

To gain insights in the current status of the economy, macroeconomic time series are often decomposed into trend, cycle and irregular components. This can be done by nonparametric band-pass filtering methods in the frequency domain or by model-based decompositions based on autoregressive moving...

We adopt an unobserved components time series model to extract financial cycles for the United States and the five largest euro area countries over the period 1970 to 2014. We find that credit, the credit-to-GDP ratio and house prices have medium-term cycles which share a few common statistical...

We introduce a dynamic network model with probabilistic link functions that depend on stochastically time-varying parameters. We adopt the widely used blockmodel framework and allow the highdimensional vector of link probabilities to be a function of a low-dimensional set of dynamic factors. The...

This paper analyzes the recently documented instability of money demand in the euro area in the framework of a Markov switching trend model. First, we consider a standard flexible price model with stable money demand, rational expectations, and an exogenous income-money ratio which follows a...

Diese Dissertation beschäftigt sich mit den makroökonomischen Konsequenzen der Annahme heterogener Firmen. Die geldpolitischen Implikationen stehen dabei im Vordergrund. In den ersten beiden, theoretisch ausgerichteten Kapiteln liegt der Fokus auf der Tatsache, dass Firmen unterschiedlich...
