An unusual impacts of war study from Karol Jan Borowiecki:
In this paper we explore whether, and to what extent, the incidence of war affects the migration intensity of 164 prominent classical composers born after 1800. We model the aggregate stock of composers in a country and find that periods of war correspond negatively with the number of artists. We also find that conflict-induced migration intensity is considerably higher for composers than for the overall population and demonstrate that the share of composers in the overall population drops due to the incidence of war. We further find that the observed outmigration substantially diminishes the country’s creative potential in the long-run.
We construct age-productivity profiles and find that the impact of wars on creative production is markedly heterogeneous – composers’ productivity was significantly higher during defensive or victorious international wars and lower during intra-state conflicts, offensive or lost international wars. the long-run.
