6.3 Production with One Variable Input(labor) In the short run,one or more inputs to the production process are fixed.In the long run,all inputs are potentially variable. □Average product(平均产出)-Output per unit of a particular input. Average product of labor=output/labor input=Q/L ▣Marginal product边际产出)-Additional output produced as an input is increased by one unit. Marginal product of labor=change in output/change in labor input=AQ/AL ❑ In the short run, one or more inputs to the production process are fixed.In the long run, all inputs are potentially variable. ❑ Average product(平均产出)-Output per unit of a particular input. Average product of labor = output/labor input = Q/L ❑ Marginal product(边际产出)-Additional output produced as an input is increased by one unit. Marginal product of labor = change in output/change in labor input = △Q/△L 6.3 Production with One Variable Input(labor)
