Understanding Entrepreneurship Has Major Implications for Economic Analysis

What are the implications for economics of recognizing entrepreneurship? They are vast. Modern/mainstream economics is, to a great extent, the outcome of expunging the entrepreneur and forcing an entrepreneurless, mechanistic view onto the economy. This facilitates the use of mathematical analysis and quantitative predictions, but these will always be wrong to the extent that there is entrepreneurship. In a sense, mainstream economics is the science of a planned or plannable economy. And the basic models even assume that there is perfect information.
