Abstract: Open banking (OB) empowers bank customers to share transaction data with fintechs and other banks. 49 countries have adopted OB policies. Consumer trust in fintechs predicts OB policy adoption and adoption spurs investment in fintechs. UK microdata shows that OB enables: i) consumers to access both financial advice and credit; ii) SMEs to establish new fintech lending relationships. In a calibrated model, OB universally improves welfare through entry and product improvements when used for advice. When used for credit, OB promotes entry and competition by reducing adverse selection, but higher prices for costlier or privacy-conscious consumers partially offset these benefits.

We assess equity-efficiency trade-offs of PACE loans. Borrowers are more likely to obtain permits related to disaster-proofing homes, and loan takeup is concentrated in areas with higher ex ante and ex post natural hazard risk. Such investments are capitalized into home values, but tax delinquency rates among borrowers increase. Although PACE loans are super senior to other debt, lenders expand their provision of mortgage credit in PACE-enabled counties.

Abstract: This paper investigates how technology affects collateral liquidity in mortgage markets. Exploiting the staggered introduction of electronic bidding across Florida’s counties, I show that foreclosure auction success increases by 39%, and price discounts shrink by 53%. I also find that credit supply expands and mortgage loan rates decrease, consistent with lenders incorporating lower foreclosure costs into lending decisions. Overall, this evidence suggests that technological modernization can improve allocative efficiency, and deepen liquidity in real estate markets.

State-level preemption of municipal gas bans reduces transition risk, expanding credit and employment in gas-intensive sectors while delaying the shift toward cleaner technologies.

This paper studies how banks shape sovereign debt issuance decisions. We argue that banks have an intrinsic preference for sovereign bonds with relatively short maturities; governments should respond to higher expected demand from banks by issuing shorter-maturity, lower-yield debt. Using detailed bank-level data on sovereign holdings across 27 European countries, and focusing on deposit-flow-induced demand from non-domestic banks, we isolate exogenous shifts in banks demand. Bank demand appears to significantly reduce the average maturity and yield of new long-term sovereign debt, but it does not increase total net issuance. Bond-level evidence confirms that the effects of bank demand on the primary market is concentrated in relatively short-tenor instruments, highlighting a compositional--but not extensive--adjustment in sovereign debt management.

Abstract: Open banking has the potential to transform lending to small and medium enterprises (“SMEs”) by allowing firms to share real-time financial data with lenders, reducing informational asymmetries and enabling more inclusive credit markets. This policy brief explores the design debate between government-led and market-led open banking models, focusing on their implications for competition, innovation, and access to finance for SMEs. 

Abstract: In statistics, samples are drawn from a population in a data-genetaring process (DGP). Standard errors measure the uncertainty in sample estimates of population parameters. In science, evidence is generated to test hypotheses in an evidence-generating process (EGP). We claim that EGP variation across researchers adds uncertainty: non-standard errors. Our crowd-sourced empirical analysis finds that non-standard errors are sizable, on par with standard errors. Their size (I) co-varies only weakly with team merits, reproducibility, or peer rating, (ii) declines significantly after peer-feedback, and (iii) is underestimated by participants.

Abstract: We investigate the effectiveness of business shutdowns to contain the Covid-19 disease. In March 2020, Italy shut down operations in selected sectors of its economy. Using a difference-in-differences approach, we find that municipalities with higher exposure to closed sectors experienced subsequently lower mortality rates. The implied life savings exceed 9,400 people over a period of less than a month. We also find that business closures exhibited rapidly diminishing returns and had large effects outside the closed businesses themselves, including spillovers to other municipalities. Overall, the results suggest that business shutdowns are effective, but should be selectively implemented and centrally coordinated.

This paper examines whether the risk of a future collateral fire sale affects lending decisions. We study US mortgage applications and exploit exogenous variation in foreclosure frictions for identification. We find lenders to be less likely to approve mortgages when anticipated losses due to uncoordinated collateral liquidations are high, and when there is elevated risk of joint collateral liquidation. These results suggest that fire sale risk has implications for credit allocation, and that lenders' collective origination decisions mitigate fire sale risk ex-post. However, we also find the effects to be significantly weaker outside periods in which fire sales are salient.
