We present a simple neoclassical model to explore how an aggregate bank-capital requirement can be used as a macroeconomic policy tool and how this additional tool interacts with monetary policy. Aggregate bank-capital requirements should be adjusted when the economy is hit by cost-push shocks...

Several countries have recently introduced national capital standards exceeding the internationally coordinated Basel III rules, thus suggesting a ‘race to the top' in capital standards. We study regulatory competition when banks are heterogeneous and give loans to firms that produce output in...

We set up a two-country, regional model of trade in financial services. Competitive firms in each country manufacture untraded consumer goods in an uncertain productive environment, borrowing funds from a bank in either the home or the foreign market. Duopolistic banks can choose their levels of...

During the last decades a consensus has emerged that it is impossible to disentangle liquidity shocks from solvency shocks. As a consequence the classical lender of last resort rules, as defined by Thornton and Bagehot, based on lending to solvent illiquid institutions appear ill-suited to this...

The Single Supervisory Mechanism was introduced to eliminate the common-pool problem and limit uncontrolled lending by national central banks (NCBs). We analyze its effectiveness. Second, we model how, by forbearing and providing refinancing credit, NCBs avoid domestic resolution costs and,...

We present a network model of the interbank market in which optimizing risk averse banks lend to each other and invest in non-liquid assets. Market clearing takes place through a tâtonnement process which yields the equilibrium price, while traded quantities are determined by means of a...
