The preferences assumed to govern intertemporal trade-offs are generally considered to be stable economic primitives, though evidence on this stability is notably lacking. We present evidence from a large field study conducted over two years, with around 1,400 individuals using incentivized intertemporal choice experiments. Aggregate choice profiles and corresponding estimates of discount parameters are unchanged over the two years and individual correlations through time are high by existing standards. However, some individuals show signs of instability. By linking experimental measures to administrative tax records, we showthat identified instability is uncorrelated with both levels and changes in sociodemographic variables.

Preferences for monetary and nonmonetary job attributes are important for understanding workers' motivation and the organization of work. Little is known, however, about how those job preferences are formed. We study how macroeconomic conditions when young shape workers' job preferences for life. Using variation in income-per-capita across U.S. regions and over time since the 1920s, we find that job preferences vary in systematic ways with experienced macroeconomic conditions during young adulthood. Recessions create cohorts of workers who give higher priority to income, whereas booms make cohorts care more about job meaning for the rest of their lives.
