Economists routinely rationalize financial behaviors and prominent empirical anomalies using time preferences inferred from money earlier or later (MEL) responses; yet theory suggests such choices could instead reflect investment returns. We conduct a lab-in-the-field experiment in Kenya combining repeated MEL, randomized large cash transfers, and an illiquid savings product. Neither time preferences nor marginal investment returns exclusively rationalize choices: randomized cash transfers significantly affect MEL responses, yet subjects also fail to arbitrage across economically equivalent MEL and savings opportunities. Our results are consistent with heterogeneity in time preferences generating the predictive power of MEL for savings decisions, providing prima facie support for routine practice.
