Modeling the Sources of Output Growth in a Panel of Countries
采用随机生产前沿模型，将产出变化分解为投入、效率和技术进步，并引入有效投入和区域异质性，实证表明这两项扩展很重要。
This article seeks to improve understanding of cross-country patterns of economic growth. It adopts a stochastic production-frontier model that allows for the decomposition of output change into input, efficiency, and technical change. The production frontier is assumed to depend on effective inputs rather than measured inputs. We develop a model in which effective inputs depend on observed factor use and a correction term that depends on variables such as education. A further extension over related work is our use of a production frontier that varies over regional country groups. Empirical results indicate that both these extensions are very important.
