Joel mentions in several of his blog posts that it is very important for a developer/software entrepreneur to have solid understanding of Economics. Yet the Fog Creek MBA book reading list does not include any Economics books.
Is there any good material that people can recommend? Obviously, I am not as concerned about mathematical treatise as foundations and basic principles. For example, I was able to find a very good high-level read on Macroeconomics:
Concise Guide to Macroeconomics
but I am yet to find anything similar on Microeconomics. Any suggestions and reading pointers would be highly appreciated.
