Please accept my apologies for not seeing your request for so long. I had extensive eye surgery about the time of your request and that severely limited my writing and online work.
My favorite macroeconomist is a friend who served as an advisor to the US Senate and to the campaign of Sen. Bernie Sanders for President. She has written numerous papers, but only recently authored a book, which went to the bestseller list immediately.
Her name is Dr. Stephanie Kelton and her book can be found here.
She is also a prolific creator of YouTube content of her lectures where a simple search of her name will provide considerable information and background. She was quite instrumental in my own enlightenment, as was Warren Mosler, a bond trader and the acknowledged founding authority of MMT.
