本文认为，作为１９９５年度诺贝尔经济学奖的获得者，罗伯特·卢卡斯在经济理论的许多方面都取得了开创性的成果：在投资理论方面，卢卡斯构造了分析竞争性行业的局部均衡模型，提出了一种证明不确定条件下理性预期均衡的存在性和唯一性的方法；在货币经济周期理论方面，提出了货币经济周期模型，以说明经济系统的内在稳定性及产出波动是由外生因素造成的；在资产定价理论方面，构造了不确定条件下资产价格决定的一般均衡模型，为分析均衡资产价格提供了有效的方法；在经济增长理论方面，提出人力资本外部性模型和“干中学”外部性模型，促进了新增长理论的产生。
This paper argues that as a winner of the 1995 Nobel Prize in Economics, Robert Lucas has made groundbreaking achievements in many aspects of economic theory: In terms of investment theory, Lucas constructed a framework for analyzing competitive industries Equilibrium model, a method to prove the existence and uniqueness of the rational expectation equilibrium under the condition of uncertainty is proposed. In terms of the theory of the monetary cycle, a monetary economic cycle model is proposed to illustrate the inherent stability of the economic system and the fluctuation of output Is caused by exogenous factors. In the aspect of asset pricing theory, a general equilibrium model of asset price decision under uncertain conditions is constructed, which provides an effective method for analyzing the equilibrium of asset prices. In the aspect of economic growth theory, it puts forward that human capital externalities Model and the “learning by doing” extrinsic model have promoted the emergence of new growth theory.
