What is Alfred Marshall's central theory?
My central contribution lies in the development of the theory of supply and demand as the primary determinant of market prices in the short run. I viewed this interaction as analogous to the blades of a pair of scissors; both supply and demand are essential in determining the equilibrium price. Furthermore, I stressed the importance of considering the time element – the short run versus the long run – in economic analysis, recognizing that different factors influence price over different durations. This framework sought to move beyond simplistic, one-sided explanations of value.
