German separation in 1949 into a communist East and a capitalist West and their reunification in 1990 are commonly described as a natural experiment to study the enduring effects of communism. We show in three steps that the populations in East and West Germany were far from being randomly...

Different from traditional gift exchange experiments, we study a field experiment where a random subsample of participants in the Swiss Labor Force Survey was sent vouchers to be used in adult training courses.
