Economic Performance Through Time
探讨经济史如何研究经济随时间变化的绩效，指出缺乏类似一般均衡理论的动态分析框架，只能描述过去经济特征并进行比较静态分析。
Economic history is about the performance of economies through time. The objective of research in the field is not only to shed new light on the economic past but also to contribute to economic theory by providing an analytical framework that will enable us to understand economic change. A theory of economic dynamics comparable in precision to general equilibrium theory would be the ideal tool of analysis. In the absence of such a theory we can describe the characteristics of past economies, examine the performance of economies at various times, and engage in comparative static analysis; but missing is an analytical understanding of the way economies evolve through time.
