This chapter provides an overview of household finance. The first part summarizes key facts regarding household financial behavior, emphasizing empirical regularities that are inconsistent with the standard classical economic model and discussing extensions of the classical model and explanations grounded in behavioral economics that can account for the observed patterns. This part covers five topics: consumption and savings, borrowing, payments, asset allocation, and insurance. The second part addresses interventions that firms, governments, and other parties deploy to shape household financial outcomes: education and information, peer effects and social influence, product design, advice and disclosure, choice architecture, and interventions that directly target prices or quantities. This chapter is divided into two parts, each of which is further divided into several sections. The first part summarizes key facts regarding household financial behavior, emphasizing empirical regularities that are inconsistent with the standard classical economic model and discussing both extensions of the classical model and explanations grounded in behavioral economics that can account for the observed patterns. This part covers five topics: (I) consumption and savings, (II) borrowing, (III) payments, (IV) asset allocation, and (V) insurance. The second part addresses interventions that firms, governments, and other parties deploy to shape household financial outcomes: (VI) education and information, (VII) peer effects and social influence, (VIII) product design, (IX) advice and disclosure, (X) choice architecture, and (XI) interventions that directly target prices or quantities. The final section of the paper (XII) concludes.
John BeshearsWe offer broad coverage of the household finance literature, but we limit the scope of our discussion along some dimensions. We focus on the U.S. institutional context and on empirical work based on U.S. data, although we do bring evidence from other wealthy countries to bear when germane and occasionally reference evidence from developing countries. We address household asset allocation but do not draw out its implications for asset pricing, which are covered by the asset pricing chapter in this handbook. Although household decisions regarding health care are relevant to household finance, we largely omit this literature from our chapter because it is covered in depth in the chapter on behavioral health economics. Finally, there is some overlap between our section on financial product design and the chapter on behavioral industrial organization; we refer readers to that chapter for related material on that topic.
Part 1: Facts
I. Consumption and SavingsBeginning with the seminal work of Modigliani and Brumberg (1954) and Friedman (1957), economists have embraced the view that households choose to save and borrow to smooth consumption over the lifecycle. Intuitively, if agents have concave utility functions over consumption, then they should spread consumption across time to optimally...
