We present a quantitative model of deposit insurance. We characterize the policymaker's optimal choices of coverage for depositors and premiums raised from banks. Premiums contribute to a deposit insurance fund that lowers taxpayers' resolution cost of bank failures. We find that riskadjusted...

Bank market power, both in the loan and deposit market, has important implications for credit provision and for financial stability. This article discusses these issues through the lens of a simple theoretical framework. On the asset side, banks choose the quality and quantity of loans. On the...

This paper examines the role of collateral in the financial system, with special emphasis on the implications for financial stability and the conduct of monetary policy. First, we review what drives the demand and supply for both real and financial collateral assets. Then we examine financial...

We quantify the impact that central bank refinancing o perations a nd f unding f acilities had at reducing the banking sector's intrinsic fragility in the euro area in 2014-2019. We do so by constructing, estimating and calibrating a micro-structural model of imperfect competition in the banking...

Rapid and large deposit outflows from banks have regained attention in the context of the March 2023 demises of Credit Suisse, SVB and other regional US banks. Moreover, the possible introduction of CBDC or a marked success of stablecoins are perceived as additional clouds over the future of...

This paper shows the existence of a central bank trilemma. When a central bank is involved in financial intermediation, either directly through a central bank digital currency (CBDC) or indirectly through other policy instruments, it can only achieve at most two of three objectives: a socially...

In financial crises, the premium on liquid assets such as US Treasuries increases alongside credit spreads. This paper explains the link between the liquidity premium and spreads. We present a theory of endogenous bank fragility arising from a coordination friction among bank creditors. The...

We model the impact of bank mergers on loan competition, banks' reserve holdings and aggregate liquidity. Banks compete in a differentiated loan market, hold reserves against liquidity shocks, and refinance in the interbank market. A merger creates an internal money market that induces financial...

This paper analyses the link between finance and growth by studying the effect that the process of financial deregulation and harmonisation of banking laws at the EU level has brought about on growth over the last 40 years. Our main findings point to the existence of a positive long-run growth...

The paper analyses the relationship between deposit insurance, debt-holder monitoring, and risk taking. In a stylised banking model we show that deposit insurance may reduce moral hazard, if deposit insurance credibly leaves out non-deposit creditors. Testing the model using EU bank level data...
