In this paper, we describe a novel iterative procedure called SISTA to learn the underlying cost in optimal transport problems. SISTA is a hybrid between two classical methods, coordinate descent ("S"-inkhorn) and proximal gradient descent ("ISTA"). It alternates between a phase of exact...

The classical doctrine of the Lender of Last Resort, elaborated by Thornton (1802) and Bagehot (1873), asserts that the Central Bank should lend to „illiquid but solvent“ banks under certain conditions. Several authors have argued that this view is now obsolete: when interbank markets are...

We analyze the consequences of activism in a regulated industry where the regulator has been captured by the industry. Unlike ordinary economic agents, activists are insensitive to monetary incentives. Moreover, they are less well informed than regulators and their actions generate dead-weight...

We argue that risk sharing motivates the bank-wide structure of bonus pay. In the presence of financial frictions that make external financing costly, the optimal contract between shareholders and employees involves some degree of risk sharing whereby bonus pay partially absorbs earnings shocks....

On 5-6 September 2012 SUERF held its 30th Colloquium “States, Banks, and the Financing of the Economy” at the University of Zürich, Switzerland. The papers included in this SUERF Study are based on contributions to the Colloquium. All the papers in this publication discuss from different...

Activist NGOs increasingly oppose industrial projects that have nevertheless been approved by public regulators. To understand this recent rise in NGO activism, we develop a theory of optimal regulation in which a regulated industry seeks to undertake a project that may be harmful to society. On...

We build a stylized dynamic general equilibrium model with financial frictions to analyze costs and benefits of capital requirements in the short-term and long-term. We show that since increasing capital requirements limits the aggregate loan supply, the equilibrium loan rate spread increases,...
