The Welfare Effects of Bank Liquidity and Capital Requirements
The stringency of bank liquidity and capital requirements should depend on their social costs and benefits. This paper investigates their welfare effects and quantifies their welfare costs using sufficient statistics. The special role of banks as liquidity providers is embedded in an otherwise standard general equilibrium growth model. Capital and liquidity requirements mitigate moral hazard from deposit insurance, which, if unchecked, can lead to excessive credit and liquidity risk at banks. However, these regulations are also costly because they reduce the ability of banks to create net ...

Economic Diversity and the Resilience of Cities
We show how local worker flow adjustment margins yield a theory-consistent sufficient statistic approximating the welfare effects of local shocks. Furthermore, we isolate a city’s insurance value as this approximation’s second-order term. Leveraging rich labor flows data across occupations, industries, and cities in France, we estimate spatial and non-spatial flows responses to local labor demand shocks. Less economically diverse French cities experience deeper contractions in gross outflows following negative shocks. In contrast, more economic concentration begets a modestly larger ...

Designing a Main Street Lending Facility
Banks add value by monitoring borrowers. High funding costs make banks reluctant to lend. A central bank can ease funding by purchasing loans, but cannot distinguish which loans require more or less monitoring, exposing it to adverse selection. A multi-tier loan pricing facility arises as the optimal institutional design setting both the purchase price and banks' risk retention for given loan characteristics. This design dominates uniform (flat) structure for loan purchases, provides the right incentives to banks and achieves maximum lending at lower rates to businesses. Both the multi-tier ...

Aggregate Implications of Deviations from Modigliani-Miller: A Sufficient Statistics Approach
A few sufficient statistics can identify the aggregate effects of distortions to firm investment in a class of general equilibrium models that can accommodate rich general equilibrium effects including endogenous firm entry. This result does not depend on the microfoundation of the distortion; one can generate inferences about aggregate effects that apply for multiple microfoundations or in cases where a fully specified model is difficult to solve. To demonstrate the relevance of themethodology, we use it to quantify the aggregate consequences of costly external equity financing and a ...
