“As real wages and generational wealth have generally risen, Americans increasingly take discretionary, positive-sum gambles (from speculative stocks to sports betting), which often feel harmless for many but can be harmful for others; these behavioral shifts, likened to side effects of GLP-1 drugs, will heighten important policy questions. Entrepreneurs and firms create new, attractive avenues for spending or risk-taking, reducing the marginal consequences of losses for those with financial cushions.”

“Using a nationally representative Feb 2023 survey (~1,000 U.S. household heads), researchers find that self-reported credit score is the primary predictor of whether and how often households overdrew; once credit score is controlled for, income, race, and education generally do not significantly predict overdraft occurrence or frequency (with one education-related exception among overdrafters).”

“Households who report greater perceived uncertainty about their future earnings and spending have higher marginal propensities to consume (MPCs), with the MPC–uncertainty relationship rising and then flattening (concave); this pattern is driven by cross-sectional differences between households and contradicts predictions of standard incomplete-markets consumption models.”
