Active wholesale financial markets help reallocate deposits across heterogeneous banks. Because of incentive problems these flows are constrained and collateral is needed. The composition of collateral matters. The use of inside assets (loans) creates a "collateral pyramid" in that cash flows...

We study the transmission mechanisms of liquidity and capital regulations as well as their effects on the economy and welfare. We propose a macro-economic model in which a regulator faces the following trade-off. On the one hand, banking regulations may reduce the aggregate supply of credit. On...

Active wholesale financial markets help reallocate deposits across heterogeneous banks. Because of incentive problems, these flows are constrained and collateral is needed. Both the volume, the value, and the composition of collateral matter. We make a distinction between "outside collateral"...

The empirical literature on systemic banking crises (SBCs) has shown that SBCs are rare events that break out in the midst of credit intensive booms and bring about particularly deep and long-lasting recessions. We attempt to explain these phenomena within a dynamic general equilibrium model...

This paper develops a general equilibrium model to analyze the link between financial imbalances and financial crises. The model features an interbank market subject to frictions and where two equilibria may (co-)exist. The normal times equilibrium is characterized by a deep market with highly...

Sudden reversals in banks' leverage cycle are modelled as the result of tensions between the abundance of liquidity and the limited capacity of the banking sector to process this liquidity and re-allocate it internally through the interbank market. I use the model to analyze the effects of...

We study whether a central bank should deviate from its objective of price stability to promote financial stability. We tackle this question within a textbook New Keynesian model augmented with capital accumulation and microfounded endogenous financial crises. We compare several interest rate...
