我们开发了一种在市场竞争的经济体中实现内生增长的模型。技术变革源于企业家追求利润的有意行为。这种利润的机会源于超边际租金。这为一种普遍观点提供了反例，即只有创新企业能够期望获得垄断或寡头垄断租金，内生技术变革才有可能。该模型具有独特的均衡，即以正速率稳定增长。由于忽略了知识溢出效应，均衡增长效率低下。这种低效率可以通过利率补贴来消除。
We develop a model of endogenous growth in an economy with competitive markets. Technical change arises from the intentional actions of entrepreneurs looking for profits. Opportunities for such profits stem from inframarginal rents. This provides a counterexample to the widespread view that endogenous technical change is possible only if innovating firms can expect to reap monopoly or oligopoly rents. The model has a unique equilibrium, which involves steady growth at a positive rate. Equilibrium growth is inefficiently low because knowledge spillover effects are neglected. The inefficiency can be eliminated by an interest rate subsidy.
