摘要：This paper targets policymakers and their advisors as well as academic
economists. It seeks to combine methodological lessons for economists and non-
economists with analysis of real-world issues and policy advice. It advocates
systemic thinking and indicates principles for systemic analysis without fully
developing such an analysis (which would require a book-length treatment). It tackles
issues that arouse great passions and require the transcendence of disciplinary
boundaries; systemic thinking may help us overcome our emotional biases and
professional narrowness.
