Alfred Marshall is a well-known economist who made nice contributions to the sphere when it was nonetheless comparatively new in the direction of the tip of the nineteenth century. But, college students usually study vital figures in economics solely briefly and in passing, though the content material taught in economics programs usually comes from good economists reminiscent of Marshall.
Certainly, Alfred Marshall is taken into account one of many founding thinkers of neoclassical economics. He was a mathematician and thinker who later turned a microeconomist. His work formalized foundational financial ideas and theories reminiscent of provide and demand, value elasticity of demand, client and producer surplus, marginal utility, and manufacturing prices to provide a number of the earliest cohesive financial fashions.
He was even instrumental in making economics its personal separate topic for the very first time at Cambridge, the place he taught for a lot of his profession. Your entire discipline of economics was vastly influenced by each Marshall and several other of his pupils, together with well-known economists Arthur Pigou and John Maynard Keynes.
Alfred Marshall’s life
Marshall was born in 1842 in London, England. He was at one time contemplating a profession within the clergy, however deserted the concept after he demonstrated vital expertise for arithmetic. Thereafter, Marshall attended St. John’s Faculty in Cambridge, incomes accolades in math (reminiscent of “Second Wrangler” within the Cambridge Mathematical Tripos) and securing his future as an instructional.
At first, Marshall wasn’t an economist – few in his time have been! Relatively, he studied topics like math, physics, philosophy, and ethics, like many different thinkers of his time. It was allegedly Marshall’s love for ethics that led him to finally research financial decision-making, as he noticed economics as a way of enhancing the human situation for the frequent man. This was a super he shared with Adam Smith, one other (earlier) vital British thinker in economics.
Thus, Marshall lent his appreciable mind to financial pursuits. In 1865, he was elected to a fellowship at St. John’s Faculty at Cambridge. He married in 1877, left St. John’s, and taught on the College of Bristol after which at Oxford for a interval afterward. In 1885, he turned the Professor of Political Financial system on the College of Cambridge, the place he remained till his retirement in 1908.

Throughout this time, Marshall turned the research of economics into its personal, self-contained self-discipline, creating the College of Economics and Politics and serving to to launch the primary formal economics diploma program at Cambridge in 1903. Famously, Marshall taught financial giants Arthur C. Pigou and John Maynard Keynes, who every went on to make their very own grand contributions to the sphere, and infrequently had nice issues to say about Marshall’s affect and instructing.
The guide Ideas of Economics was Alfred Marshall’s magnum opus. He labored on it from 1881 to 1890. It was quickly acknowledged as a hit and an excellent achievement in economics upon its publishing. But Marshall was unhappy with the limiting assumptions of classical economics (a few of which he helped to popularize!), so his work shouldn’t be seen as a definitive snapshot of his financial beliefs.
As a substitute, Marshall was eager to have his college students surpass him and exchange his fashions with extra correct ones, such that he was recognized to present them copies of his Ideas of Economics with signed messages reminiscent of ‘To [name], within the hope that in the end [they] will render this treatise out of date’.
Alfred Marshall died in Cambridge in 1924, on the age of 81.
Alfred Marshall’s contributions to economics
Marshall’s contributions to economics are quite a few. As a former mathematician, he formulated many ideas within the discipline with equations. This strategy helped him formally outline most of the ideas talked about originally of this text, which different economists of his time had not been in a position to do.
However, he additionally tried to distill financial insights into language that was comprehensible by non-mathematicians, a vital talent for profitable economists even in right now’s world. That is evidenced by his inserting math equations and graphs solely within the footnotes and appendices of his Ideas of Economics, not the principle textual content.
In addition to Ideas of Economics, Marshall’s different economics works embody the 1879 textual content The Economics of Business, which he co-wrote together with his spouse Mary Paley (a former pupil of his, and one of many first-ever feminine economics college students. She was denied a level on the premise of being a girl, a discriminatory coverage that her husband Alfred Marshall supported; however however she was an excellent economist in her personal proper).

Alfred Marshall was additionally a vital determine in popularizing the concept of “considering on the margin”. Marginal evaluation right now is a core and foundational idea in economics, the place somebody’s determination relies on the profit that the following unit supplies, not the sum complete of all models. The so-called “Marginal Revolution” started with economists William Jevons, Carl Menger, and Léon Walras within the 1870s.
Marshall is one in every of a “second wave” of economists who, seeing the brilliance of those marginal concepts, set about integrating them into financial fashions. John Keynes, his former pupil, mentioned this of his work: “[William] Jevons noticed the kettle boil and referred to as out with the delighted voice of a kid; Marshall too had seen the kettle boil and sat down silently to construct an engine.”
In accordance with Keynes, Marshall’s writing additionally put an finish to a debate over whether or not value or demand decided the worth of things in a market, positing convincingly that it was really each. As such, Marshall is credited with growing the concept the value and output provided of a very good are decided by the intersection of provide and demand. This strategy is so foundational as to look apparent to economists right now, which speaks to the success of his thought!
Marshall additionally launched early concepts of the totally different “time horizons” that economists incessantly reference. He identified that within the brief run, adjustments in demand are likely to have extra results on markets than prices, whereas in the long term supply-side info like prices can considerably form markets. In accordance with Keynes, Marshall was additionally the primary to supply an precise components for value elasticity of demand – which earlier authors had talked about, however not formalized. He did the identical with client and producer surplus as nicely, which French engineer and later self-taught economist Jules Dupuit had initially described.
Marshall’s works have been broad, protecting much more subjects than these. His college students Keynes and Pigou, and later economists like Joseph Schumpeter, have a number of recorded quotes in regards to the thoroughness of Marshall’s Ideas which might be available on-line. These embody the truth that Marshall’s fashions and formulae hidden within the footnotes of the Ideas usually supplied options to issues that have been solely considered in a while.
So, subsequent time you’re learning economics – significantly microeconomics subjects – don’t be stunned to listen to Alfred Marshall being given the credit score!
