The Management Of Consumer Credit

Consumer credit is an integral part of many western societies. This book provides a comprehensive view of how credit-granting institutions operate and discusses the relationship between the strategic objectives set by senior management and the operational strategies employed by credit professionals working at the coal face of credit provision.

This book explains how financial institutions, such as banks and finance houses, manage their portfolios of credit cards, loans, mortgages and other types of retail credit agreements. The second edition has been substantially updated, with new chapters on capital requirements, Basel II, scorecard and portfolio monitoring.

This article provides an introduction to a law review symposium by the Journal of Law, Economics, and Policy on our book (co-authored with Michael E. Staten), Consumer Credit and the American Economy (Oxford 2014). The conference, held November 2014, collects several articles responding to and building on the research agenda laid out by our book. For those who have not read the book, this article is intended to summarize several of the main themes of the book, including discussion of economic models of consumer credit usage, trends in consumer credit usage over time, the use of high-cost credit, and behavioral economics.

This text addresses the challenges that result from change and growth within the financial services and credit industry. It features a comprehensive case study and discusses issues related to technology, the Internet and on-line credit.

The use of credit scoring - the quantitative and statistical techniques to assess the credit risks involved in lending to consumers - has been one of the most successful if unsung applications of mathematics in business for the last fifty years. Now with lenders changing their objectives from minimising defaults to maximising profits, the saturation of the consumer credit market allowing borrowers to be more discriminating in their choice of which loans, mortgages and credit cards to use, and the Basel Accord banking regulations raising the profile of credit scoring within banks there are a number of challenges that require new models that use credit scores as inputs and extensions of the ideas in credit scoring. This book reviews the current methodology and measures used in credit scoring and then looks at the models that can be used to address these new challenges. The first chapter describes what a credit score is and how a scorecard is built which gives credit scores and models how the score is used in the lending decision. The second chapter describes the different ways the quality of a scorecard can be measured and points out how some of these measure the discrimination of the score, some the probability prediction of the score, and some the categorical predictions that are made using the score. The remaining three chapters address how to use risk and response scoring to model the new problems in consumer lending. Chapter three looks at models that assist in deciding how to vary the loan terms made to different potential borrowers depending on their individual characteristics. Risk based pricing is the most common approach being introduced. Chapter four describes how one can use Markov chains and survival analysis to model the dynamics of a borrower's repayment and ordering behaviour . These models allow one to make decisions that maximise the profitability of the borrower to the lender and can be considered as part of a customer relationship management strategy. The last chapter looks at how the new banking regulations in the Basel Accord apply to consumer lending. It develops models that show how they will change the operating decisions used in consumer lending and how their need for stress testing requires the development of new models to assess the credit risk of portfolios of consumer loans rather than a models of the credit risks of individual loans.
