(6) For every value of N there is a corresponding marginal productivity of labour in the wage-goods industries; and it is this which determines the real wage.

（6）对于N的每一值，在雇佣商品工业中都有相应的劳动边际生产率;正是这一点决定了实际工资。

The ordinary theory of distribution, where it is assumed that capital is getting now its marginal productivity (in some sense or other), is only valid in a stationary state.

普通的分配理论假设资本现在正在获得其边际生产率（在某种意义上或其他意义上）， 仅在静止状态下有效。

Chapter vi of Professor Carver's Distribution of Wealth clearly envisages interest as the factor which brings into equilibrium the marginal disutility of waiting with the marginal productivity of capital.

Carver 教授的财富分配第六章清楚地将利息设想为使等待的边际负效用与资本的边际生产力达到平衡的因素。
