This paper explores how different types of financial regulation could combat many of the phenomena that were observed in the financial crisis of 2007 to 2009. The primary contribution is the introduction of a model that includes both a banking system and a “shadow banking system” that each...

We analyze a variant of the Diamond-Dybvig (1983) model of banking in which savers can use a bank to invest in a risky project operated by an entrepreneur. The savers can buy equity in the bank and save via deposits. The bank chooses to invest in a safe asset or to fund the entrepreneur. The...

The drafting of macroprudential regulation is largely being driven by the need by policy makers to meet timetables that have been agreed. The legislative drive is taking place without any clear theoretical framework to organise the objectives. In this article we propose two principles that any...
