We study optimal capital requirement regulation in a dynamic quantitative model in which nonfinancial firms, as well as households, hold deposits. Firms hold deposits for precautionary reasons and to facilitate the acquisition of production inputs. Our theoretical analysis identifies a novel...

I analyze the impact of raising capital requirements on the quantity, composition, and riskiness of aggregate investment in a model in which firms borrow from both bank and non-bank lenders. The bank funds loans with insured deposits and costly equity, monitors borrowers, and must maintain a...

We survey 149 leading academic researchers on bank capital regulation. The median (average) respondent prefers a 10% (15%) minimum non-risk-weighted equity-to-assets ratio, which is considerably higher than the current requirement. North Americans prefer a significantly higher equity-to-assets...

Market participants and policymakers alike were surprised by the large, prolonged dislocations in credit market arbitrage trades during the second half of 2015 and the first quarter of 2016. In this paper, we examine three explanations proposed by market participants: increased idiosyncratic...

I develop a theoretical model to examine the effect of capital requirements on risk taking and market structure of banks. Within a portfolio choice model, I allow for heterogeneous productivity among banks and consider the simultaneous capital regulation with a leverage ratio and a risk-weighted...

We introduce a model of the banking sector that formally incorporates a buffer function of capital. Heterogeneous banks choose their portfolio risk, bank size, and capital holdings. Banks voluntarily hold equity when the buffer effect against the risk of default outweighs the cost advantages of...
