Roy Zilberman and William Tayler.
Last year the Bank organised a research competition to coincide with the launch of the One Bank Research Agenda. In this guest post, the authors of the winning paper in that competition, Roy Zilberman and William Tayler from Lancaster Business School, summarise their work on optimal macroprudential policy.
Can macroprudential regulation go beyond its remit of financial stability and also contain inflation and output fluctuations? We think it can and argue that macroprudential regulation, in the form of countercyclical bank capital requirements, is a superior instrument to both conventional and financially-augmented Taylor (1993) monetary policy rules. This is especially true in responding to financial shocks that drive output and inflation in opposite directions, as also observed at the start of the recent financial crisis (see Gilchrist, Schoenle, Sim and Zakrajsek (2016)). This helps to effectively shield the real economy without the need for a monetary policy interest rate intervention. Put differently, a well-designed simple and implementable bank capital rule can achieve optimal policy associated with zero welfare losses.
