4 – 8 September 2017



15:30 to 19:00

Intended for


Academic economists and central bankers.



Participants should be comfortable following Master level courses in microeconomics.



The course provides an overview of recent research on the relationship between competition, prudential regulation, and the stability of the banking system. The course starts with a review of models of perfect and imperfect competition in banking and of the problems of adverse selection and moral hazard in credit markets. The second lecture discusses the role of banks in providing insurance against liquidity risk, which offers an explanation for the existence of bank runs and a rationale for deposit insurance. The third lecture examines the possible existence of a trade-off between competition and financial stability. The fourth lecture presents an overview of bank regulation from Basel I to Basel III, and discusses some key features of the new regulation such as its loan pricing effects, the rationale for the cyclical adjustment of risk-sensitive capital requirements, and the optimal regulation of liquidity risk. The course concludes with a review of recent topics on banking research such the effect of shadow banks on the effectiveness of bank capital regulation and the economics of bank supervision, with a special reference to the design of the Single Supervisory Mechanism of the European Central Bank.
