We examine transitions from agriculture to the modern sector in the mid-20th century Finland. Our empirical strategy builds on the evacuation and resettlement of 11% of the Finnish population after WWII. Displaced farmers were given new farms that were similar to their old ones. Nevertheless, we find that forced migration increased the likelihood of leaving agriculture by 10-22 percentage points and long-term earnings by 11-28%. We show that part of these effects is due to plausibly exogeneous networks created by the initial evacuations. However, both stated and revealed preferences suggest that attachment to a place was a major deterrent for structural change at this period. Joint with Roope Uusitalo and Markus Jäntti.
