Shocks in the financial sector caused the great recession of 2008 and pulled down the real economy. To implement financial dynamics in a stylized DSGE-framework we use behavioral elements in expectations to produce waves of bull and bear cycles in the financial intermediation process, that have...

We develop an extended real business cycle (RBC) model with financially con-strained firms and non-pledgeable intangible capital. Based on a model-consistentseries for firms' borrowing conditions, we find, within a structural vector autoregres-sion (SVAR) framework, that, in response to an...

We investigate the role of consumer confidence in the transmission of monetary policy shocks from an empirical and theoretical perspective. Standard VAR based analysis suggests that an empirical measure of consumer confidence drops significantly after a monetary tightening and amplifies the...

This paper challenges the view that the observed negative correlation between the Federal Funds rate and the interest rate implied by consumption Euler equations is systematically linked to monetary policy. By using a Monte Carlo experiment, we show that stochastic risk premium disturbances have...

This paper evaluates business cycle and welfare effects of cross-country mortgage market heterogeneity for a monetary union. By employing a calibrated two-country New Keynesian DSGE model with collateral constraints tied to housing values, we show that a change in cross-country institutional...

In this paper we study the drivers of fluctuations in the Irish housing market by developing a dynamic stochastic general equilibrium (DSGE) model of Ireland as a member of the European Monetary Union (EMU). We estimate the model with Bayesian methods using time series for both Ireland and the...

In this paper we quantitatively evaluate the hypothesis that the Great Moderation is partly the result of a less activist monetary policy. We simulate a New Keynesian model where the central bank can only observe a noisy estimate of the output gap and fnd that the less pronounced reaction of the...

In this paper we carry over a static version of a New Keynesian Macro Model to a monetary union. For a similar approach see Uhlig (2002). We will show in particular that a harmonious functioning of a monetary union critically depends on the correlation structure of shocks that hit the currency...

This paper addresses the credit channel in Germany by using aggregate data. We present a stylized model of the banking firm, in which banks decide on their loan supply in the light of uncertainty about the future course of monetary policy. Applying a vector error correction model (VECM), we...

Dieses vorläufige Papier beinhaltet keinerlei neuen Erkenntnisse, sondern fasst lediglich einige zentrale Aspekte der makroökonomischen Lerntheorie (siehe Evans, Honkajohja (2001)) knapp zusammen. Es wird der Frage nachgegangen ob rationale Erwartungsgleichgewichte lernbar sind. Lernen...
