Student Loans, Access to Credit, and Consumer Credit Demand.

This article examines how increased student loan debt, driven by rising tuition costs, affects borrowers' demand for and access to other forms of consumer credit. Using a life cycle model of consumption and borrowing combined with a detailed empirical analysis of U.S. credit and educational data, the study finds that higher student loan debt raises borrowers' demand for additional consumer debt but simultaneously restricts their access to it due to tighter credit supply. The net effect varies by credit market: in loosely underwritten markets such as auto loans and installment sales contracts, student loan debt increases borrowing, whereas in tightly underwritten markets like credit cards and mortgages, it reduces credit use and credit limits. These findings highlight important policy implications regarding the spillover effects of federally guaranteed student loans on broader consumer credit markets and potential constraints on consumption smoothing for indebted households.
