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 demonstrate how the introduction of liability-side feedbacks affects the properties of a quantitative model of systemic risk. The model is known as RAMSI and is still in its development phase. It is based on detailed balance sheets for UK banks and encompasses macro-credit risk, interest and...

Cyber attacks can impair banks operations and precipitate bank runs. When digital infrastructure is shared, banks defend themselves by investing in cybersecurity but can free-ride on the security measures of others. Ex ante free-riding by banks interacts with the ex post coordination frictions...

The complex web of exposures and interlinkages across the financial system highlights the relevance of network analysis in understanding systemic risk and guiding the design of financial regulation. This paper discusses how network models—and those based on epidemiological approaches in...

Why do politicians sometimes pursue policies with uncertain outcomes? We present a model in which politicians are unable to pre-commit to a status quo policy, and where investors and voters face a conflict over the division of output. Politicians may deviate from the status quo and pursue risky...
