What is the effect of Central Bank Digital Currency (CBDC) on financial stability? We answer this question by studying a model of financial intermediation with an endogenously determined probability of a bank run, using global games. As an alternative to bank deposits, consumers can also store...

Banks are reluctant to tap central bank backup liquidity facilities and use the borrowed funds for loans to the real economy. We show that excessively parsimonious borrowing and lending can arise in a stigma-free model where the banking sector has an incentive to overissue deposits. Banks don't...

This paper explores monetary-macroprudential policy interactions in a simple, calibrated New Keynesian model incorporating the possibility of a credit boom precipitating a financial crisis and a loss function reflecting financial stability considerations. Deploying the countercyclical capital...

In this paper we assess the merits of financial condition indices constructed using simple averages versus a more sophisticated alternative that uses factor models with time varying parameters. Our analysis is based on data for 18 advanced and emerging economies at a monthly frequency covering...

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...

To what extent can private firms' external equity substitute for debt financing in a banking crisis? To answer this question, I use firm-level data and firm-bank linkages to estimate the causal effect of an imported lending cut from a large German bank on firms' capital structure and real...
