economic study for the last 300 years has been based on peoples opinions of mechanisms that are still the same as 300 hundred years ago. the interest rate mechanism, the credit and equity market, bonds and government borrowing. as it stands you have a few schools of thought that have different opinions on how these mechanisms should control economies. this is where the economic thought has been invested. however is that just outspoken people with opinions or justifiable research. my opinion that the evolution of economics is not based on opinions but progression of mechanisms and tools. other methods of generating capital and controlling that capital within an economy. this is real innovation rather than opinions and research and should be the future of economics.
