Alfred Marshall, as a person who left behind great deeds, was very persistent in what he did. The quantity of his published books and others publications can not be, in it's entirety, compared with the knowledge passed onto his students. In his work and teachnings, he estabilished neoclassical school and became recognized and esteemed leader also know as „The economist for economists“. Althought he was guided by experiences of his predecessor Adam Smith and his teories, Marshall's contributions to economics werw in (the area of the theory of value on redistribution) where he proves that supply and demand are main factors when determinating prices as primary value expression. Marshall wrote about that topic in his work „Principles of economics“ which later became a part of curriculum of English schools and shaped the teaching of economics. In his teories, he seeks to improve the understanding of the economics in a way that proves usefulness, elasticity of supply and demand, price ratio and economic conditions (surpluses and shortages in the economy). Although, the influence of many other economists was approved after the Marshall, all the facts and conclusions are based on he previous materials which indicates that not so many new theories surpassed the old ones.
