Public enterprise and the rise and fall of labor share

Developed economies experienced a rise and fall in labor share (LS) in the postwar period. We present a novel explanation of these trends – public enterprise employment. We document a link between it and both LS and wage compression in 15 developed nations. We then build a model that shows how overstaffing public enterprises can increase LS and reduce wage inequality. Overstaffing directly increases public enterprise LS and indirectly increases private sector LS by reducing available labor. We examine several public enterprise reforms. Consistent with the model’s predictions, reforms reduce public enterprise LS permanently and private sector LS temporarily.
