Economic Growth

一个关键的经济问题是贫穷国家或地区是否倾向于 比富人增长得更快：是否有自动的力量 随着时间的推移，人均收入水平趋于一致， 产品？ 本课题的目的就是分析这一问题 在三个背景下。 首先，美国各州的个人收入 从1840年到现在;第二，国内生产总值超过 1950年至1985年，6个欧洲国家的70个地区;第三， 100个国家的国民账户和其他变量， 从1960年到1985年。 将建立一个理论框架，其基础是 新古典主义增长模型的扩展。 视角下 在这些扩展中，最近的理论分为三类： 用技术进步理论取代外生技术进步理论， 技术变革;用新技术取代外生人口增长 生育理论;并取代通常的假设， 资本收益递减假设 不断的回报。 这些增长理论模型随后将得到检验 与美国的数据相对应，欧洲和国际 contexts. 这项研究很重要，因为它将提供一个 更好地了解决定经济增长的因素， 发展

A key economic issue is whether poor countries or regions tend to grow faster than rich ones: are there automatic forces that lead to convergence over time in levels of per capita income and product? The purpose of this project is to analyze this question in three contexts. First, personal income across the U.S. states from 1840 to the present; second, gross domestic product for over 70 regions of 6 European countries from 1950 to 1985; and third, national-account and other variables for about 100 counties from 1960 to 1985. A theoretical framework will be developed which is based on extensions of the neoclassical growth model. From the perspective of these extensions, recent theories sort into three categories: replacing exogenous technological progress by theories of technological change; replacing exogenous population growth by theories of fertility; and replacing the usual assumption of diminishing returns of capital by the assumption of asymptotically constant returns. These growth theory models will then be tested with data corresponding to the U.S., European, and international contexts. This research is important because it will provide a better understanding of the factors determining economic growth and development.
