To detect the quantity theory of money, we follow Lucas (1980) by looking at scatter plots of filtered time series of inflation and money growth rates and interest rates and money growth rates. Like Whiteman (1984), we relate those scatter plots to sums of two-sided distributed lag coefficients...

Against the background of the recent housing boom and bust in countries such as Spain and Ireland, we investigate in this paper the macroeconomic consequences of cross-border banking in monetary unions such as the euro area. For this purpose, we incorporate in an otherwise standard two-region...

In this paper we investigate the effects of uncertainty shocks on economic activity using a Dynamic Stochastic General Equilibrium (DSGE) model with heterogenous agents and a stylized banking sector. We show that frictions in credit supply amplify the effects of uncertainty shocks on economic...

In this paper we set up a New-Keynesian model with a heterogenous banking sector to analyze liquidity problems on the interbank market. The presence of an interbank market is essential to consider a situation where an increased liquidity supply by the central bank is only partially passed on to...

We study the design of optimal monetary policy (Ramsey policies) in a model with sticky prices and unionized labour markets. Collective wage bargaining and unions monopoly power tend to dampen wage fluctuations and to amplify employment fluctuations relatively to a DNK model with walrasian...

Using a standard dynamic general equilibrium model, we show that the interaction of staggered nominal contracts with hyperbolic discounting leads to inflation having significant long-run effects on real variables.

We assess the quantitative importance of expectation effects of regime shifts in monetary policy in a DSGE model that allows the monetary policy rule to switch between a "bad" regime and a "good" regime. When agents take into account such regime shifts in forming expectations, the expectation...

In the recent New Keynesian literature a standard assumption is that the price for which an intermediate good is sold to the final good firm is equal to the marginal costs of the intermediate good firm. However, there is empirical evidence that this need not to hold. This paper introduces price...
