Alfred Marshall's theory, particularly his concepts of supply and demand, elasticity, and consumer surplus, is widely used by economists, policymakers, and business analysts. Economists apply his principles to understand market behavior and predict economic trends. Policymakers utilize his insights to craft regulations and economic policies that influence market efficiency and welfare. Additionally, business analysts use Marshall’s framework to evaluate market conditions and make strategic decisions.
In his development of economic theory, Alfred Marshall included the concept of demand, the aggregate effect of consumers who desire products or services.
This Theory was propounded by H.H Gossen and called Gossen second law and developed by Alfred Marshall and all the credit is given to Alfred Marshall. This theory states that a retoinal consumer spend his total budget between among the goods he will derived the satisfaction from the additional goods.
Alfred marshall made a heroic assumption of 'cetris paribus' which means other things being equal/constant in economics. This assumption he used for the theories he put forth viz. theory of demand,theory of supply,theory of diminishing marginal utility,etc. Most of his theories come under the sub field- micro economics. The assumption of cetris paribus is the main, there are many others for each law besides cetris paribus.
In his ground-breaking treatise Principles of Economics (1890), Alfred Marshall promoted the neoclassical premises of price, output, and production, which are the basis for the "supply and demand" theory of economics.
Macroeconomics uses a microeconomic foundation to make it analysis. Microeconomic theory often uses econometric data taken from macroeconomics to come up with theories of economic relationships.
