Recent Developments in Banking Theory and Regulation



Rafael Repullo (CEMFI)



31 August - 4 September 2020



15:30 to 18:30 CET

Intended for


Academic economists and central bankers



Participants should be comfortable with Master level courses in microeconomics



The course provides an overview of some recent banking literature, with especial reference to the role of market power, regulation, and the stance of monetary policy on risk-taking. The course starts with a review of the industrial organization of banking, focusing on the determination of deposit and loan rates, and the implications for bank profitability, under different market structures that range from perfect competition to monopoly. The second session examines the possible existence of a trade-off between competition and financial stability, and the potential contribution of bank capital regulation to ameliorate it. The third session deals with the transmission of monetary policy through the banking system, covering among other things the possible existence of a reversal rate below which further reductions in the policy rate contract lending. The fourth session discusses the risk-taking channel of monetary policy, focusing on the role of market power and the effect of macroprudential policies. The last session reviews research on topics related to the regulation of the Basel Committee such as its loan pricing effects, the rationale for the cyclical adjustment of risk-sensitive capital requirements, and the optimal regulation of liquidity risk. Throughout the course emphasis is placed on the critical examination of the models proposed to address the various topics.
