INCREASING MARGINAL RETURNS: In the short-run production of a firm, an increase in the variable input results in an increase in the marginal product of the variable input. Increasing marginal returns typically surface when the first few quantities of a variable input are added to a fixed input. Compare this with decreasing marginal returns. You should also compare this with economies of scale associated with long-run production.

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.
