Two aspects of systemic risk, the risk that banks fail together, are modeled and their interaction examined. First, the ex-post aspect, in which the failure of a bank brings down a surviving bank as well, and second, the ex-ante aspect, in which banks endogenously hold correlated portfolios...

This Paper studies the efficient pricing of large-value payment systems in the presence of unobservable heterogeneity across banks. It is shown that the optimal pricing scheme for a public monopoly system involves quantity discounts in the form of a decreasing marginal fee. This is also true...

Systemic risk is modeled as the endogenously chosen correlation of returns on assets held by banks. The limited liability of banks and the presence of a negative externality of one bank’s failure on the health of other banks give rise to a systemic risk-shifting incentive where all banks...

Fire sales that occur during crises beg the question of why sufficient outside capital does not move in quickly to take advantage of fire sales, or in other words, why outside capital is so slow-moving. We propose an answer to this puzzle in the context of an equilibrium model of capital...

The Riksbank faces challenges with regard to each of its three core functions, conducting monetary policy with the objective of stabilising inflation around the inflation target and resource utilisation around a sustainable level, promoting a safe and efficient payment system and thereby...

This paper seeks to understand the interplay between banks, bank regulation, sovereign default risk and central bank guarantees in a monetary union. I assume that banks can use sovereign bonds for repurchase agreements with a common central bank, and that their sovereign partially backs up any...

One of the several regulatory failures behind the global financial crisis that started in 2007 has been the regulatory focus on individual, rather than systemic, risk of financial institutions. Focusing on systemically important assets and liabilities (SIALs) rather than individual financial...

Bailout expectations have led banks to behave imprudently, holding too little capital and relying too much on short term funding to finance long term investments. This paper presents a model to rationalize a constructive ambiguity approach to liquidity assistance as a solution to forbearance....

Following the financial crisis of 2008/9, there has been renewed interest in what Greenwald and Stiglitz dubbed ‘pecuniary externalities’. Two that affect borrowers and lenders balance sheets in pro-cyclical fashion are described, along with measures that might help curb their destabilising...

Banks’ behaviour can be influenced by both monetary policy and regulatory capital requirements. This paper explores the interaction between these two policy tools in promoting better lending decisions by banks. We develop and calibrate a model of bank lending to examine what an optimal...
