The overall natural rate of unemployment will then be affected by changes in the demand or supply in these different segments of the overall labor market and by changes in the composition of the aggregate labor force. Several major changes in recent decades have affected labor supply and demand.
There are arguments relating inflation and unemployment. For example, inflation causes real wages to fall without cuts in nominal wages, which are difficult. Therefore it allows more efficient pricing of labor, and less unemployment. Or, falling unemployment allows workers to demand wage increases, which are passed along as price increases and inflation.
