Based on administrative data, we analyze empirically the effects of stricter conditionality for social assistance receipt on welfare dependency and high school completion rates among Norwegian youths. Our evaluation strategy exploits a geographically differentiated implementation of conditionality. The causal effects are identified on the basis of larger-thanexpected within-municipality changes in outcomes that not only coincide with the local timing of conditionality implementation, but do so in a way that correlates with individual ex ante predicted probabilities of becoming a social assistance claimant. We find that stricter conditionality significantly reduces welfare claims and increases high school completion rates.JEL Classification: H55, I29, I38, J18

We exploit supply-driven heterogeneity in the expansion of cable television across Norwegian municipalities to identify developmental effects of commercial television exposure during childhood. We find that higher exposure to commercial television reduces cognitive ability and high school graduation rates for young men. The effects are largest for exposure during pre-school and elementary school age. We find no effect on high school completion for women, suggesting availability of non-educational media content as a factor in the widening educational gender gap. Based on time-use data, we show that a possible explanation is that television-watching crowds out reading more for boys than girls.JEL Classification: J13, J16, J24, L82

We evaluate the impact on youth crime of a welfare reform that tightened activation requirements for social assistance clients. The evaluation strategy exploits administrative individual data in combination with geographically differentiated implementation of the reform. We find that the reform reduced crime among teenage boys from economically disadvantaged families. Stronger reform effects on weekday versus weekend crime, reduced school dropout, and favorable long-run outcomes in terms of crime and educational attainment, point to both incapacitation and human capital accumulation as key mechanisms. Despite lowered social assistance take-up we uncover no indication that loss of income support pushed youth into crime.
