One of the roots of the recent global financial crisis has been seen in the design of subprime mortgage contract leading to high sensitivity of such type of loans to house price changes. The market of subprime loans, especially in the last years preceding the crisis, has been highly financed by...

This paper uncovers a novel mechanism by which bubbles crowd in capital investment. If capital is initially depressed by a binding credit constraint, injecting a bubble triggers a savings glut. Higher returns in a new bubbly equilibrium attract additional investors who expand investment at the...

According to empirical studies, the life cycle of labor supply volatility exhibits a U-shaped pattern. This may lead to the conclusion that demographic change induces a drop in output volatility. We present an overlapping generations model that replicates the empirically observed pattern and...

Theoretical models of downward real wage rigidity generate asymmetric wage cyclicality with real wages being rigid in "bad" times but upwardly flexible during "good". In this paper we use an administrative panel dataset from Germany to establish that such asymmetries are very salient in Germany....

This paper investigates the risk-taking channel of monetary policy on the asset side of banks' balance sheets. We use a factor-augmented vector autoregression (FAVAR) model to show that aggregate lending standards of U.S. banks, e.g. their collateral requirements for firms, are significantly...

We examine how borrowing constraints affect monetary transmission and the trade-off of a welfare maximizing central bank. We develop a sticky price model where money serves as the means of payment and ex-ante identical agents borrow/lend among each other. The credit market is distorted as...

We discuss properties of alternatives or complements to GDP as a measure of welfare at business cycle frequencies. We argue that these figures are not useful to measure the welfare costs of business cycles. First, data is not available at an appropriate quality and frequency. Second, since the...

We analyze the relationship between firm-specific shocks and aggregate fluctuations. In particular, profitability of firms affected by a negative shock worsens. To the extent that the banks cannot distinguish between aggregate and firm-specific profitability shocks, they will adjust interest...

Did the increase in counterparty risk perception in the interbank market since autumn 2007 contribute to the severe contraction of the US economy? To address this question we introduce interbank market uncertainty in a DSGE model with frictional financial intermediation. Interbank uncertainty is...

The topic of this paper is the estimation uncertainty of the Stock-Watson and Gonzalo-Granger permanent-transitory decompositions in the framework of the co-integrated vector autoregression. We suggest an approach to construct the confidence interval of the transitory component estimate in a...
