We propose a model of asset encumbrance by banks subject to rollover risk and study the consequences for fragility, funding costs, and prudential regulation. A bank’s choice of encumbrance trades off the benefit of expanding profitable investment funded by cheap long-term secured debt against...

We examine why rational voters support risky “policy gambles”, even when detrimental to welfare, over maintaining a safe status quo. We present a model of electoral competition with two groups of agents. Elites own the means of production and choose how much future output they require as...

We study the two-way interaction between central banks and financial markets using a beauty contest framework. The analysis identifies when asset prices reveal useful information about fundamentals and when they reflect back the central bank’s pronouncements. In equilibrium, the central bank...

This paper develops an analytical model of contagion in financial networks with arbitrary structure. We explore how the probability and potential impact of contagion is influenced by aggregate and idiosyncratic shocks, changes in network structure, and asset market liquidity. Our findings...

This paper analyses how the risk-sharing capacity of the financial system varies over the business cycle, leading to procyclical fragility. We show how financial imperfections contribute to underinsurance by entrepreneurs, generating an externality that leads to the build-up of systematic risk...

We present a general equilibrium model of intermediation designed to capture some of the key features of the modern financial system. The model incorporates financial constraints and state-contingent contracts, and captures the spillovers associated with asset fire sales during periods of...
