Put another way, the full employment and the absence of involuntary unemployment correspond to the case where the real wage equals the marginal cost to workers of supplying labor for hire on the market (the "marginal disutility of employment"). That is, the real wage rate and the amount of employment correspond to a point on the aggregate supply curve of labor that is assumed to exist. In contrast, a situation with less than full employment and thus involuntary unemployment would have the real wage above the supply price of labor. That is, the employment situation corresponds to a point above and to the left of the aggregate supply curve of labor: the real wage would be above the point on the aggregate supply curve of labor at the current level of employment; alternatively, the level of employment would be below the point on that supply curve at the current real wage.
