Endogenous Innovation in the Theory of Growth
论证了有目的的、追求利润的知识投资在长期增长中的关键作用，回顾了新古典增长理论和内生增长理论，并讨论了相关实证证据及基于内生技术进步的模型。
This paper makes the case that purposive, profit-seeking investments in knowledge play a critical role in the long-run growth process. First, the authors review the implications of neoclassical growth theory and the more recent theories of ‘endogenous growth.’ Then they discuss the empirical evidence that bears on the modeling of long-run growth. Finally, the authors describe in more detail a model of growth based on endogenous technological progress and discuss the lessons that such models can teach us.
