Banks, Credit Reallocation, and Creative Destruction (jointly with Christian Keuschnigg and Johannes Matt)

Abstract: How do banks facilitate creative destruction and shape firm turnover? We develop a dynamic general equilibrium model of bank credit reallocation with endogenous firm entry and exit that allows for both theoretical and quantitative analysis. By restructuring loans to firms with poor prospects and high default risk, banks not only accelerate the exit of unproductive firms but also redirect existing credit to more productive entrants. This reduces banks' dependence on household deposits that are often supplied inelastically, thereby relaxing the economy's resource constraint. A more efficient loan restructuring process thus fosters firm creation and improves aggregate productivity. It also complements policies that stimulate firm entry (e.g., R&D subsidies) and renders them more effective by avoiding a crowding-out via a higher interest rate.

Profit Taxation and Bank Risk Taking

Revision requested by the Journal of Money, Credit and Banking

Abstract:  How can tax policy improve financial stability? Recent studies suggest large stability gains from eliminating the debt bias in corporate taxation. It is well known that this reform reduces bank leverage. This paper analyzes a novel, complementary channel: risk taking. We model banks’  portfolio choice under moral hazard and emphasize the ‘incentive function’ of equity. We find that (i) an allowance for corporate equity (ACE) and a lower tax rate discourage risk taking and offer stability and welfare gains, (ii) a revenue-neutral ACE unambiguously improves financial stability, and (iii) capital regulation and deposit insurance influence the risk-taking effects of taxation.
