Looking at smoking-behavior it can be shown that there are differences concerning the time-preference-rate. Therefore this has an effect on the optimal schooling decision in the way that we assume a lower average human capital level for smokers. According to a higher time-preference-rate we...

This paper investigates two mechanisms through which education may affect cognitive skills in adolescence: the role of instructional quantity and the timing of instruction with respect to age. To identify causal effects, I exploit a school reform carried out at the state level in Germany as a...
