HYPERBOLIC DISCOUNTING, BORROWING AVERSION AND DEBT HOLDING

摘要

Analysis of an original Internet-based survey reveals that debt holding is related to time discounting through: (ⅰ) present bias, measured by the degree of declining impatience in the generalized hyperbolic discount function; (ⅱ) borrowing aversion, captured by a sign effect in that future losses are discounted at lower rates than future gains; and (ⅲ) impatience, measured by the overall discount rate. Hyperbolic respondents are classified naieve if their answers reveal them to be time-inconsistent procrastinators, and otherwise sophisticated. Naieve respondents with more steeply declining impatience are more likely to be debtors. The sign effect relates negatively to borrowing. Survey responses indicative of high or declining impatience are associated with credit card borrowing and other overborrowing indicators.
