We conduct a lab-in-the-field experiment to examine the long-term effects of riots in Assam in India on a range of economic and behavioural outcomes. We find that individuals who live in the villages that have been heavily and moderately affected by riots are more trustworthy, more likely to be competitive and have higher levels of self-confidence under competitive situations. They exhibit more anti-social preferences but are less likely to be dishonest than individuals in the unaffected areas. The estimates are stronger and more often statistically significant when considering heavily affected areas than moderately affected areas - suggesting stronger influence on those who were directly exposed to or experienced the riots. Using survey measures, we observe that individuals in areas that were heavily exposed to riots have higher levels of trust, higher tendency toward altruism, and lower memory capacity.
