HYSTERESIS: The notion that the natural rate of unemployment is affected by historical events, especially the onset of a business-cycle contraction. Hysteresis results because unemployed resources are permanently changed, through loss of job skills or seniority, making them less employable when the contraction is over. The labor market itself might be permanently change. The result is a permanent increase in structural and frictional unemployment and a higher natural unemployment rate. Alternatively, a prolonged business-cycle expansion can generate long-term changes that cause a permanent decrease in the natural unemployment rate.

Second, effective demand means that consumption expenditures are based on actual income, not full employment or equilibrium income. Lastly, important savings and investment determinants include income, expectations, and other influences beyond the interest rate. These three assumptions imply that the economy can achieve a short-run equilibrium at less than full-employment production.
