Alfred Marshall (July 26, 1842 – July 13, 1924), was one of the most influential economists of his time.

Through his work, applying mathematical principles to economic issues, economics became established as a scientific discipline. Marshall attempted to bring together the classical approach, ...view middle of the document...
Although Marshall's views were never completely accepted by all economists, his ideas were influential in advancing understanding of economic relationships, which are fundamental to the successful development and maintenance of a stable, prosperous society that benefits all its members. Modern economists owe the linkage between price shifts and curve shifts to Marshall. Marshall contributed to the "marginalist revolution" with the idea that consumers attempt to equate prices to their marginal utility. Marshall introduced the concept of time in the determination of price through his proposed different market "periods":
1. Market period—goods produced for sale on the market are in fixed supply, for example in a fish market. Prices quickly adjust to clear markets.
2. Short period—industrial capacity is taken as given. This is the time period in which the supply can be increased through additional labor and raw materials, but not capital improvements, in order to maximize profits.
3. Long period—the time when capital "appliances," such as factories and machines, may be increased. Profit-maximizing equilibrium determines both industrial capacity and the level at which it is operated.
4. Very long period—technology, population trends, habits, and customs may vary in very long period models.
