I have a new Econlib article, which will appear in two parts. It summarizes the results of my research on MMT.
Note that this sentence in Part 1 has a typo:
“In Singapore, both the interest rate and the exchange rate are endogenous.”
It should have been interest rates and the money supply are endogenous. It might be corrected by the time you read the article.
Thanks to commenter Garrett for pointing that out.
