Optimal Localized Production Experience and Schooling
研究物质资本积累、学校教育和干中学三个经济增长因素，通过生产经验积累的调整成本模型，分析技术变化对收敛速度的影响，为增长理论提供最优控制解。
Three factors of economic growth, i.e., physical capital accumulation, schooling and learning by doing, are investigated. The special relationship between the first factor and the other two is modeled through adjustment costs in production experience accumulation whenever the production technique changes. This generates a nontrivial two state variable control problem. Necessary and sufficient conditions for optimality are given. The steady state and the path to it are unique. It is shown that, among others, technique changes deter whereas learning by doing enhances the speed of convergence to the steady state.
