The slave trade and the origins of mistrust in Africa : a replication study of Nunn and Wantchekon (American Economic Review, 2011)

Nunn & Wantchekon (2011) detect a long-lasting impact of the slave trade on current trust levels across ethnic groups in Africa. They use data from Afrobarometer's wave 3 to construct trust measures. While I can perfectly replicate the original OLS and 2SLS findings in this wave starting from the same raw data, using data from more recent waves which were collected after the paper was published, I fail to replicate some of the paper's central findings. Plausible explanations are discussed
