On Endogenizing Long-Run Growth
梳理了内生增长理论的三种长期增长引擎,并构建一个统一模型来评估不同因素对长期增长率的影响,对理解经济制度与政策如何影响增长有参考价值。
ABSTRACT: This assessment of recent theoretical work on endogenous growth identifies three different engines of long-run growth: (i) the asymptotic average product of capital is positive; (ii) labor productivity increases as an external effect of capital accumulation; (iii) there are feedback effects on the cost of accumulating knowledge or innovating. A general model encompassing all three is considered, and then used to review different proposed determinants of long-run growth rates. The contribution of endogenous growth theory has been to create a framework in which to explain why economic institutions and policies can have long-run effects on growth rates.
