We use the Bosnian Living Standards Measurement Study (LSMS) survey to show that conflict-induced displacement of agricultural households dramatically affects the adoption of new technologies in agriculture. We exploit the heterogeneity in the level of violence in the pre-war location to account for selection bias. This natural experiment seems to be a source of exogenous variation in our case because violence aims at ethnic cleansing, without economic consideration. We find that the displaced are less likely than stayers to adopt fertiliser and pesticide.
