This article considers the implications of complex systems models for the study of economics and the evaluation of public policies. I argue that complexity can enhance current approaches to formal economic analysis, but does so in ways that complement current approaches. I further argue that while complexity can influence how public policy analysis is conducted, it does not delimit the use of consequentialist approaches to policy comparison to the degree initially suggested by Hayek and most recently defended by Gaus.

This paper discusses the history of the use of cross-country regressions in modern growth economics. These regressions continue to be the workhorse of empirical growth analysis even though their meaning continues to be controversial. I argue that the early interpretations of these regressions have proven to be inappropriate and led to substantial exaggeration of the evidentiary support for various new growth theories. On the other hand, I argue that these regressions have a valuable role to play in identifying the modern analog of stylized facts for growth behavior.
