He held two presentations about benefit-cost analyses of early childhood education programs (e.g., the Perry Preschool Project) and about effects of early childhood education programs to reduce inequality. He reported that different programs have different effects and that in the U.S. investment in early education throughout a life span yields returns of 2:1 to 16:1 in total, for example, because of higher earnings and less delinquency in the group that took part in the early childhood program. After the presentations there was plenty of opportunity for discussion. In particular, it was debated how the U.S. results could be transferred to the situation of early education in Germany.
