If historical shocks influence educational outcomes, how long does the effect last, and does it differ among ethnic groups? This study answers these questions by exploiting the historical experiment of partition—that is the splitting of the British Raj into India and Pakistan—and by presenting a theoretical model that explains the trade-offs such a shock uncovers for different ethnic groups that have to decide between assimilation through education and maintaining their ethnic specificity. We use different rounds of Pakistan social and living standard measurement (PSLM) survey and analyze the educational outcomes of the grandchildren of partition (i.e., whose grandparents were born during the partition). We show that the scar from partition is long-lasting, as the present generation is still living under its influence. More importantly, our results reveal the different adaptation strategies of ethnic and cultural groups in the long run.
