In economics, the marginal product of labor (MPL) is the change in output that results from employing an added unit of labor. ==Definition== The marginal product of a factor of production is generally defined as the change in output associated with a change in that factor, holding other inputs into production constant. The marginal product of labor is then the change in output (''Y'') per unit change in labor (''L''). In discrete terms the marginal product of labor is: : In continuous terms, the ''MPL'' is the first derivative of the production function: : 〔Perloff, J., ''Microeconomics Theory and Applications with Calculus'', Pearson 2008. p. 173.〕 Graphically, the ''MPL'' is the slope of the production function. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Marginal product of labor」の詳細全文を読む スポンサード リンク
