Switching costs and adverse selection in the market for credit cards: new evidence

To explain persistence of credit card interest rates at relatively high levels, Calem and Mester (AER, 1995) argued that informational barriers create switching costs for high-balance customers. As evidence, using data from the 1989 Survey of Consumer Finances, they showed that these households were more likely to be rejected when applying for new credit. In this paper, they revisit the question using the 1998 and 2001 SCF. Further, they use new information on card interest rates to test for pricing effects consistent with information-based switching costs. The authors find that informational barriers to competition persist, although their role may have declined. ; Also issued as Payment Cards Center Discussion Paper No. 05-09Credit cards

The Impact of Technology and Regulation on the Geographical Scope of Banking

We review how technological advances and changes in regulation may shape the (future) geographical scope of banking. We first review how both physical distance and the presence of borders currently affect bank lending conditions (loan pricing and credit availability) and market presence (branching and servicing). Next we discuss how technology and regulation have altered this impact and analyse the current state of the European banking sector. We discuss both theoretical contributions and empirical work and highlight open questions along the way. We draw three main lessons from the current theoretical and empirical literature: (1) Bank lending to small businesses in Europe may be characterized both by (local) spatial pricing and resilient (regional and/or national) market segmentation; (2) Because of informational asymmetries in the retail market, bank mergers and acquisitions seem the optimal route of entering another market, long before cross-border servicing or direct entry are economically feasible; (3) Current technological and regulatory developments may to a large extent remain impotent in further dismantling the various residual but mutually reinforcing frictions in the retail banking markets in Europe. We conclude the paper by offering pertinent policy recommendations based on these three lessons.geographical scope, banking, lending relationships, technology, and regulation.

Liquidity Constraints and Imperfect Information in Subprime Lending

We present new evidence on consumer liquidity constraints and the credit market conditions that might give rise to them. Our analysis is based on unique data from a large auto sales company that serves the subprime market. We first document the role of short-term liquidity in driving purchasing behavior, including sharp increases in demand during tax rebate season and a high sensitivity to minimum down payment requirements. We then explore the informational problems facing subprime lenders. We find that default rates rise significantly with loan size, providing a rationale for lenders to impose loan caps because of moral hazard. We also find that borrowers at the highest risk of default demand the largest loans, but the degree of adverse selection is mitigated substantially by effective risk-based pricing.

What Will Technology Do to Financial Structure?

This paper looks at how advances in information and telecommunications technologies have been changing the structure of the financial system by lowering transaction costs and reducing asymmetric information. Households and smaller businesses can now raise funds in securities markets as financial institutions have become better at unbundling risks while financial products can be distributed more efficiently through electronic networks. These changes have reduced the role of traditional financial intermediaries overall efficiency by lowering the costs of financial contracting. Despite these benefits technological progress presents policymakers with some important challenges. First markets for financial products become larger and more contestable, defining geographic and product markets narrowly becomes more problematic. Second, financial consolidation and the trend towards new activities of financial intermediaries require the exploration of new methods to preserve the safety and soundness of the financial system. A combined system of vigilant supervision and constructive ambiguity to deal with failures of larger institutions should be capable of mitigating the potential for increased risk-taking and help preserve the health of the financial system.

Observing Unobservables: Identifying Information Asymmetries with a Consumer Credit Field Experiment

Information asymmetries are important in theory but difficult to identify in practice. We estimate the empirical importance of adverse selection and moral hazard in a consumer credit market using a new field experiment methodology. We randomized 58,000 direct mail offers issued by a major South African lender along three dimensions: 1) the initial "offer interest rate" appearing on direct mail solicitations; 2) a "contract interest rate" equal to or less than the offer interest rate and revealed to the over 4,000 borrowers who agreed to the initial offer rate; and 3) a dynamic repayment incentive that extends preferential pricing on future loans to borrowers who remain in good standing. These three randomizations, combined with complete knowledge of the Lender's information set, permit identification of specific types of private information problems. Specifically, our setup distinguishes adverse selection from moral hazard effects on repayment, and thereby generates unique evidence on the existence and magnitudes of specific credit market failures. We find evidence of both adverse selection (among women) and moral hazard (predominantly among men), and the findings suggest that about 20% of default is due to asymmetric information problems. This helps explain the prevalence of credit constraints even in a market that specializes in financing high-risk borrowers at very high rates.Information asymmetries, field experiment, adverse selection, moral hazard, development finance, credit markets, microfinance

An empirical analysis of subprime consumer credit demand

We test the interest rate sensitivity of subprime credit card borrowers using a unique panel data set from a UK credit card company. What is novel about our contribution is that we were given details of a randomized interest rate experiment conducted by the lender between October 2006 and January 2007. We find that individuals who tend to utilize their credit limits fully do not reduce their demand for credit when subject to increases in interest rates as high as 3 percentage points. This finding is naturally interpreted as evidence of binding liquidity contraints. We also demonstrate the importance of truly exogenous variation in interest rates when estimating credit demand elasticities. We show that estimating a standard credit demand equation with nonexperimental variation leads to seriously biased estimates even when conditioning on a rich set of controls and individual fixed effects. In particular, this procedure results in a large and statistically significant 3-month elasticity of credit card debt with respect to interest rates even though the experimental estimate of the same elasticity is neither economically nor statistically different from zero

Managing consumer credit risk

On July 31, 2001, the Payment Cards Center of the Federal Reserve Bank of Philadelphia hosted a workshop that examined current credit risk management practices in the consumer credit industry. The session was led by Jeffrey Bower, senior manager in KPMG Consulting’s financial services practice. Bower discussed "best practices" in the credit risk management field, including credit scoring, loss forecasting, and portfolio management. ; In addition, he provided an overview of developing new methodologies used by today's risk management professionals in underwriting consumer risk. This paper summarizes key elements of Bower's presentation.Consumer credit ; Credit cards

Collateralised loan obligations (CLOs) : a primer

The following descriptive paper surveys the various types of loan securitisation and provides a working definition of so-called collateralised loan obligations (CLOs). Free of the common rhetoric and slogans, which sometimes substitute for understanding of the complex nature of structured finance, this paper describes the theoretical foundations of this specialised form of loan securitisation. Not only the distinctive properties of CLOs, but also the information economics inherent in the transfer of credit risk will be considered, so that we can equally privilege the critical aspects of security design in the structuring of CLO transactions

The winner's curse in banking

Theoretical studies have noted that loan applications rejected by one bank can apply at another bank, systematically worsening the pool of applicants faced by all banks. This paper presents the first empirical evidence of this effect and explores some additional ramifications, including the role of common filters, such as commercially available credit scoring models, in mitigating this adverse selection, implications for de novo banks, implications for banks' incentives to comply with fair lending laws, and macroeconomic effects.Bank loans ; Credit scoring systems
