I am not a professional economist by trade, but I can tell you that Keynesian is an economic theory that explains how the total spending in the economy of a country, which the experts call aggregate demand, will affect the economic output and the inflation rates in that economy. However, the term has been used and unfortunately abused in order to describe many different ideas and concepts over the years. This particular economic theory was named after John Maynard Keynes an influential and, for many students of the discipline, a revolutionary British economist who came up with a new vision and understanding of the economic problems.
You can read more about this British economist in the link that I am including next so you can review it. Here it is: econlib.org/library/Enc/bios/Keynes.html Enjoy the reading!
