Based on a unique dataset provided by a retail bank, we analyze borrower heterogeneity in the debt response to interest rate decreases and credit limit increases in revolving consumer credit. Our key findings show that 1) the debt response to interest rate decreases by borrowers who choose voluntary minimum repayments (VMR) is about four times as large as the response by borrowers not choosing this option, 2) VMR borrowers demand credit limit increases which are more than twice as high as those of non-VMR borrowers following interest rate cuts, and 3) VMR borrowers’ marginal propensity to consume out of credit limit increases is almost 30% stronger. These results are most likely to be caused by sophisticated present-biased individuals choosing to commit and shed new light on the role of non-standard borrower preferences in consumer credit.

Mergers and acquisitions improve market efficiency by capturing synergies between firms. But takeovers also impose externalities (both positive and negative) on the remaining firms in the industry. This paper describes a new equilibrium concept designed to explain and predict takeovers in this setting. We experimentally compare the new equilibrium concept to that of competing concepts in situations without and with externalities. Moreover, we examine the predicted dynamics of takeovers and outcome implications of those dynamics. Our experimental results support the predictions of the new equilibrium concept and provide implications for further empirical tests.
