This paper develops a model of an economy where bank credit supports both productive investment and individual consumption smoothing in the face of idiosyncratic income risk. Bank credit is constrained by bank equity capital. When policy-makers inject equity capital during financial crises, they...

This paper studies optimal bank capital requirements in a model of endogenous bank funding conditions. I find that requirements should be higher during good times such that a macroprudential "buffer" is provided. However, whether banks can use buffers to maintain lending during a financial...

Countercyclical bank capital requirements have emerged as a popular regulatory tool to help smooth financial cycles. The idea is to reduce capital requirements when exogenous shocks cause aggregate bank capital to decrease so that regulation does not needlessly constrain banks' supply of credit....

The financial sector bailouts seen during the Great Recession generated substantial opposition and controversy. We assess the welfare benefits of government-funded emergency support to the financial sector, taking into account its effects on risk-taking incentives. In our quantitative general...

We analyze the impact of interest rate policy on financial stability in an environment where banks can experience runs on their short-term liabilities, forcing them to sell assets at fire-sale prices. Price adjustment frictions and a state-dependent risk of financial crisis create the...

We study constrained-efficient bank capital regulation in a model with market-imposed equity requirements. Banks hold equity buffers to insure against sudden loss of access to funding. However, in the model, banks choose to only partially self-insure because equity is privately costly. As a...

We propose a macroeconomic model in which adverse selection in investment drives the amplification of macroeconomic fluctuations, in line with prominent roles played by the credit crunch and collapse of the asset-backed security market in the financial crisis. Endogenous lending standards emerge...

Should monetary policy lean against housing market booms? We approach this question using a small-scale, regime-switching New Keynesian model, where housing market crashes arrive with a logit probability that depends on the level of household debt. This crisis regime is characterized by an...

This paper analyzes the implications of the global financial cycle for conventional and unconventional monetary policies and macroprudential policy in small, open economies such as Canada. The paper starts by summarizing recent work on financial cycles and their growing correlation across...

This paper explores whether different funding structures-including the source, instrument, currency, and counterparty location of funding-affected the extent of financial stress experienced in various countries and sectors during the Covid-19 spread in early 2020. We measure financial stress...
