We analyze securities trading by banks and the associated spillovers to the supply of credit.Empirical analysis has been elusive due to the lack of securities register for banks. We use a unique, proprietary dataset that has the investments of banks at the security level for 2005-2012 in...

By combining the approaches of Gertler and Karadi (2011) and Bernanke et al. (1999), I develop a DSGE model with leverage constraints both in the banking and in the non-financial firm sector. I calibrate this "full model" to US data. In a world with only a monetary policy and a productivity...

The role of bank capital as a propagation channel of shocks is strongly pronounced in recent macroeconomic models. In this paper, we show how the evolution of bank capital depends on the share of non-state-contingent assets in banks’ balance sheets and present the consequences for...

In the presence of financial frictions, banks' capital position may constrain their ability to provide loans. The banking sector may thus have important feedback effects on the macroeconomy. To shed new light on this issue, we combine two approaches. First, we use microeconomic balance sheet...

This paper tests for the sensitivity of R&D to financing constraints conditional on restrictions in external financing. Financing constraints of firms are identified by an exogenously calculated rating index. Restrictions in external financing are determined by (i) the specific time period...

We study the equilibrium properties of a business cycle model with financial frictions and price adjustment costs. Capital-constrained entrepreneurs finance risky projects by borrowing from banks. Banks, in turn, make loans using equity and deposits. Because financial contracts are not...
