I am very interested in hearing  comments of any kind about anything I’ve written on this site.  In my view, macroeconomics as presently practiced has woefully little really useful information about our real economy. Many years ago I received my undergraduate degree in mathematics and find the math generally used in economics to be mainly a cloak to give an impressive sheen to remarkably little significant content.  I appreciate any criticisms to make my essays more accurate or more clear. No doubt there is plenty of opportunity for readers to suggest improvement.
