IZA DP No. 6927: Savings and Prize-Linked Savings Accounts
revised version published in: Journal of Economic Behavior and Organization, 2014, 107 (A), 86-106
Many households have insufficient savings to handle moderate and routine consumption shocks. Many of these financially fragile households also have the highest lottery expenditures as a proportion of income. This combination suggests that Prize-Linked Savings (PLS) accounts, that combine principal-security with lottery-type jackpots, can increase savings among these at-risk households. Results from an online experiment show that the introduction of PLS accounts increase total savings and reduce lottery expenditures significantly, especially among individuals with the lowest levels of savings and income. The results imply that PLS accounts offer a plausible market-based solution to nudge individuals to increase savings.
