We develop a model of bank risk-taking with strategic sovereign default risk. Domestic banks invest in real projects and purchase government bonds. While an increase in bond purchases crowds out profitable investments, it improves the government's incentives to repay and therefore lowers its...

We answer the following question: Does regulating the banking network increase systemic risk in the entire financial network in the presence of unregulated shadow banks? In order to answer this question, we introduce a formal definition of systemic risk based on the equilibrium state dynamics...

If monetary policy is to aim at financial stability, how would it change? To analyze this question, this paper develops a general-form, axiomatic framework. Financial stability objectives are shown to make a monetary authority more conservative and more aggressive. Conservative as it sets higher...

This paper shows that a rate hike has countervailing effects on banks' risk appetite. It reduces risk when the debt burden of the banking sector is modest. We model a regulator whose trade-off between bank risk and credit supply is derived from a welfare function. We show that the regulator...

This paper contributes to the debate on the adequate regulatory treatment of non-bank financial intermediation (NBFI). It proposes an avenue for regulators to keep regulatory arbitrage under control and preserve sufficient space for efficient financial innovation at the same time. We argue for a...

We analyse the poisonous interaction between bank rescues, financial fragility and sovereign debt discounts. In our model balance sheet constrained financial intermediaries finance both capital expenditure of intermediate goods producers and government deficits. The financial intermediaries face...

We investigate the effectiveness of "Keynesian" fiscal stimuli when government deficits and debt rollovers are (possibly partially) financed by balance sheet constrained financial intermediaries. Because financial intermediaries operate under a leverage constraint, deficit financing of fiscal...

This paper explores financial stability policies for the shadow banking system. I tie policy options to economic mechanisms for shadow banking that have been documented in the literature. I then illustrate the role of shadow bank policies using three examples: agency mortgage real estate...
