Digitalen Bildungsmedien in Form von multimedialen, digitalen, elektronischen bzw. interaktiven Schulbüchern wird ein großes Potential für die in vielen Unterrichtsfächern und in der Wissenschaft diskutierte Veränderung und Etablierung neuer Lehr- und Lernprozesse zugeschrieben. Im Vordergrund dieser Arbeit steht die empirisch validierte Entwicklung eines interaktiven Schulbuchs für die ökonomische Bildung.

We present the results of a randomized intervention in schools to study how teaching financial literacy affects risk and time preferences of adolescents. Following more than 600 adolescents, aged 16 years on average, over about half a year, we provide causal evidence that teaching financial literacy has significant short-term and longer-term effects on risk and time preferences. Compared to two different control treatments, we find that teaching financial literacy makes subjects more patient, less present-biased, and slightly more risk-averse. Our finding that the intervention changes economic preferences contributes to a better understanding of why financial literacy has been shown to correlate systematically with financial behavior in previous studies. We argue that the link between financial literacy and field behavior works through economic preferences. In our study, the latter are also related in a meaningful way to students' field behavior.

We present the results of a randomized intervention to study how teaching financial literacy to 16-year old high-school students affects their behavior in risk and time preference tasks. Compared to two different control treatments, we find that teaching financial literacy makes subjects behave more patiently, more time-consistent, and more risk-averse. These effects persist for up to almost 5 years after our intervention. Behavior in the risk and time preference tasks is related to financial behavior outside the lab, in particular spending patterns. This shows that teaching financial literacy affects economic decision-making which in turn is important for field behavior.
