how did the economics curses began in the USA​

Answer 1

Answer:

(Bloomberg Opinion) — The Federal Reserve spent the past several years shifting to a policy framework that emphasizes employment more and inflation less. This made it more patient with business cycle expansions, which is one reason median household incomes grew more in the late 2010s than they did in the late 1990s.

But an unappreciated hero in facilitating this policy shift is the energy revolution that has transformed domestic energy markets.

For decades, one could argue, the Fed raised interest rates more in response to tight energy markets than tight labor markets. Because the U.S. has now achieved a certain kind of energy independence, those energy market constraints no longer exist as they did in the past, letting the Fed truly wait for signs of tight labor markets before raising rates.
