“We extract data for 144 music composers born in the 19th century and calculate four measures that approximate peer competition: (1) the average number of peers residing in the same location and time; (2) the lifetime average share of peers located in the same location and time; (3) the share of a composer’s life spent in one of the main locations for music, where peer group size – and thus competition – is potentially at its highest; and (4) the quality of fellow composers (calculated as the sum of quality indices of all composers located in the same location and time).“
