Hi Terry
Thank you for your interest in this subject.
See https://www.quora.com/Why-isnt-the-USA-economy-growing-as-fast-as-the-Chinese-economy and
I hope these three articles provide an indication of the vastness of the subject. I have conducted private research and so far co-authored two books and written a further five plus another over 400 articles, about 30 coauthored and about 100 unpublished. You can see my list of books at https://www.quora.com/profile/George-Tait-Edwards
47 years of research so far,and I think another three to thirteen to go.
Happy reading.
