I find this omission to be super weird. Also: Advocates of empowering local communities talk about increasing the number of times a dollar is used within the community. Just to make up an example: Before WalMart a dollar is used 10 times before leaving, after WalMart a dollar is used 2 times. What's that measure called? And that's microeconomics, right? If it's important for microeconomics, why isn't it important for macro too? Also: Big money has to chase big investments. Probably because of transaction costs and limited attention. So while there's innumerable small opportunities, they remain uncapitalized. How do we (society) get these things done? Find a way to scale up. Empower more people to make more investments. So instead of a billion dollar fund looking at 10 large investments, we have 1,000 million dollar funds looking at 10,000 modest investments.
