High unemployment rates have a significant negative effect when interacting with increases in inequality. High unemployment also has a negative effect on long-run economic growth. Unemployment may seriously harm growth because resources sit idle, because it generates redistributive pressures and distortions, because it idles human capital and deters its accumulation, because it drives people to poverty, because it results in liquidity constraints that limit labor mobility, and because it erodes individual self-esteem and promotes social dislocation, unrest and conflict. Policies to control unemployment and reduce its inequality-associated effects can strengthen long-run growth.
