In the endogenous growth model, the economy does not reach a steady growth rate equal to the growth of labor plus an exogenous rate of labor productivity growth. Instead, saving and investment decisions can generate self-sustaining growth at a permanently higher rate. This situation is in sharp contrast to the neoclassical model, in which only a transitory increase in growth above the steady state is possible. The reason for this difference is because of the externalities on R&D, diminishing marginal returns to capital do not set in. 老师, 不太听得懂内生模型. 并且这段话麻烦您说一下关键点, 主要是它和neoclassical对比, 两者的根本区别, 谢谢
