We investigate the empirical significance of borrowing constraints in the market for consumer loans. We set up a theoretical model of consumer loan demand, which in the presence of credit rationing implies restrictions on the elasticities of loan demand with respect to the interest rate and the...

From 2011 to 2014, the Brazilian government conducted a heavily advertised major credit expansion program through government banks as part of its effort to stimulate the economy. Using administrative data on individual-level borrowing and spending, we find that the program led to a substantial...

Compiling new liability-level data from the balance sheets of personal bankruptcy filers, we document that a sizable share of reported liabilities are "shadow debt," debt not reported to credit bureaus that often arises from the non-payment of goods and services. We use this new data to evaluate...

Information asymmetries are known in theory to lead to inefficiently low credit provision, yet empirical estimates of the resulting welfare losses are scarce. This paper leverages a randomized experiment conducted by a large fintech lender to estimate welfare losses arising from asymmetric...

We present both theory and evidence that increased competition may decrease rather than increase consumer welfare in subprime credit markets. We present a model of lending markets with imperfect competition, adverse selection and costly lender screening. In more competitive markets, lenders have...

Digital credit has expanded rapidly in Africa, mostly in the form of short-term, high-interest loans offered via mobile money. Loan terms are often opaque and consumer financial literacy is low, providing opportunities for predatory lending. A regression discontinuity analysis shows no negative...

Recent empirical studies have found that consumption is more sensitive to current income than the life-cycle, permanent income hypothesis would predict.The present paper studies a model in which the fraction of consumers exhibiting excess sensitivity is endogenously determined. The presence of...

We establish two underappreciated facts about costly search. First, unless demand is perfectly inelastic, search frictions can result in significant deadweight loss by decreasing consumption. Second, whenever cross-price elasticities are non-zero, costly search in one market also affects...

There is little evidence on how the large market for credit score improvement products affects consumers or credit market efficiency. A randomized encouragement design on a standard credit builder loan (CBL) identifies null average effects on whether consumers have a credit score and the score...

This paper finds that banks and non-banks respond differently to increased competition in consumer credit markets. Increased competition and the greater threat of failure induces banks to specialize more in relationship business lending, and surviving banks are more profitable. However,...
