Economists concentrate on economics and mainly use statistical analysis with an all-embracing theoretical framework and method of analysis. In this respect, I am an outsider. Yet they are not concerned about things outside economics, whereas I am.
經濟學家則專注經濟，主要是用統計分析，有周延的理論架構及研究方法，這方面我外行；但經濟以外的東西，他們不管，我管。
