We present a dynamic general equilibrium model with agency costs, where heterogenous firms choose among two alternative instruments of external finance - coporate bonds and bank loans. We characterize the financing choice of firms and the endogeous financial structure of the economy. The...

We analyze the properties of the natural rate of interest in an economy where nominal debt contracts generate a spread between loan rates and the policy interest rate. In our model, monetary policy has real effects in the flexible-price equilibrium, because it affects the credit spread. Relying...

We consider a simple extension of the basic new-Keynesian setup in which we relax the assumption of frictionless financial markets. In our economy, asymmetric information and default risk lead banks to optimally charge a lending rate above the risk-free rate. Our contribution is threefold....

We present a dynamic general equilibrium model with agency costs, where heterogeneous firms choose among two alternative instruments of external finance - corporate bonds and bank loans. We characterize the financing choice of firrms and the endogenous financial structure of the economy. The...

Interbank money markets have been subject to substantial impairments in the recent decade, such as a decline in unsecured lending and substantial increases in haircuts on posted collateral. This paper seeks to understand the implications of these developments for the broader economy and monetary...

We study the optimal combination of conventional (interest rates) and unconventional (credit easing) monetary policy in a model where agency costs generate a spread between deposit and lending rates. We show that unconventional measures can be a powerful substitute for interest rate policy in...
