In most OECD countries the policy instrument of choice to prevent people from working in the shadows has been deterrence. While deterrence is well founded from a theoretical point of view, the empirical evidence on its success is weak: tax policies and state deregulation appear to work much better. The discussion of the recent literature underlines that in addition to economic opportunities, the overall situation in the labor market and unemployment are crucial for an understanding of the dynamics of the shadow economy.

Many initiatives worldwide aim at improving financial literacy through targeted education programs, yet there is little evidence regarding their effectiveness. We examine the impact of a short financial education program on teenagers in German high schools.Our findings reveal that the training program significantly increases teenagers' interest in financial matters and their financial knowledge, especially their ability to properly assess the riskiness of assets. Behaviorally, we observe a decrease in the prevalence of self-reported impulse purchases, but at the same time find no evidence of a significant increase in savings. Our data reveals strong gender differences already before adulthood: Girls show less interest in, and self-assessed knowledge of, financial matters, and are less likely to save.

We study the impact of financial education on intertemporal choice in adolescence. The educational program was randomly assigned among high school students, and choices were measured using an incentivized experiment. Students who participated in the program make more time-consistent choices; are more likely to allocate payments to a single payment date, as opposed to spreading payment across two dates; and display increased consistency of choice with the law of demand. These findings suggest that financial education increases the quality of intertemporal decision-making and decreases narrow bracketing. (JEL C93, D14, D15, I21, J13)
