Since Basel II was introduced in 2008, two approaches to calculating bank capital requirements have co-existed: lenders' internal models, and a less risk-sensitive standardised approach. Using a unique dataset covering 7 million UK mortgages for 2005–15, and novel identification, we provide...

We analyze the role of auctions in managing the default of a clearing member in a generic central counterparty (CCP). We first consider three established alternative sealed bid auction formats in which clearing members simultaneously submit bids for a defaulting clearing member's portfolio:...

This paper provides a means of estimating how ‘Solvency II' regulations — introduced in the European Union in January 2016 — might affect UK life insurers' incentives to hold different types of financial assets, and how these asset holdings are likely to vary in the face of hypothetical...

This paper assesses the value of multiple requirements in bank regulation using a novel empirical rule‑based methodology. Exploiting a dataset of capital and liquidity ratios for a sample of global banks in 2005 and 2006, we apply simple threshold-based rules to assess how different...
