Everything about Alfred Marshall totally explained
Alfred Marshall (born
26 July 1842 in
Bermondsey,
London,
England, died
13 July 1924 in
Cambridge, England) was an
English economist and one of the most influential
economists of his time. His book,
Principles of Economics (
1890), brings the ideas of
supply and demand, of
marginal utility and of the
costs of production into a coherent whole. It became the dominant economic textbook in England for a long period.
Biography
Marshall grew up in the London suburb of
Clapham and was educated at the
Merchant Taylor's School, Northwood and
St John's College, Cambridge, where he demonstrated an aptitude in mathematics, achieving the rank of
Second Wrangler in the 1865
Cambridge Mathematical Tripos. Although he wanted early on, at the behest of his father, to become a clergyman, his success at
Cambridge University led him to take an academic career. He became a professor in
1868 specialising in
political economy. He desired to improve the mathematical rigor of economics and transform it into a more scientific profession. In the
1870s he wrote a small number of tracts on international trade and the problems of protectionism. In
1879, many of these works were compiled together into a work entitled
The Pure Theory of Foreign Trade: The Pure Theory of Domestic Values. In the same year (1879) he published
The Economics of Industry with his wife
Mary Paley Marshall.
While Marshall took economics to a more mathematically rigorous level, he didn't want
mathematics to overshadow economics and thus make economics irrelevant to the layman. Accordingly, Marshall tailored the text of his books to laymen and put the mathematical content in the footnotes and appendices for the professionals. In a letter to his protégée,
A.C. Pigou, he laid out the following system: "(1) Use mathematics as shorthand language, rather than as an engine of inquiry. (2) Keep to them till you've done. (3) Translate into English. (4) Then illustrate by examples that are important in real life (5) Burn the mathematics. (6) If you can’t succeed in 4, burn 3. This I do often."
Marshall had been Mary Paley's professor of political economy at Cambridge and the two were married in
1877, forcing Marshall to leave his position at Cambridge in order to comply with celibacy rules at the university. He became a principal at
University College, Bristol, again lecturing on political economy. He perfected his
Economics of Industry and published it more widely in England as an economic curriculum; its simple form stood upon sophisticated theoretical foundations. Marshall achieved a measure of fame from this work, and upon the death of
William Jevons in
1881, Marshall became the leading British economist of the scientific school of his time.
Marshall returned to Cambridge to take the seat as
Professor of Political Economy in 1884 on the death of
Henry Fawcett. At Cambridge he endeavored to create a new
tripos for economics, which he'd only achieve in 1903. Until that time, economics was taught under the Historical and Moral Sciences Triposes which failed to provide Marshall the kind of energetic and specialized students he desired.
Marshall began his seminal work, the
Principles of Economics, in 1881, and he spent much of the next decade at work on the treatise. His plan for the work gradually extended to a two-volume compilation on the whole of economic thought; the first volume was published in 1890 to worldwide acclaim that established him as one of the leading economists of his time. The second volume, which was to address foreign trade, money, trade fluctuations, taxation, and collectivism, was never published at all.
He served as
President of the first day of the 1889
Co-operative Congress.
Over the next two decades he worked to complete his second volume of the
Principles, but his unyielding attention to detail and ambition for completeness prevented him from mastering the work's breadth. The work was never finished and many other, lesser works he'd begun work on - a memorandum on trade policy for the
Chancellor of the Exchequer in the
1890s, for instance - were left incomplete for the same reasons.
His health problems had gradually grown worse since the 1880s, and in 1908 he retired from the university. He hoped to continue work on his
Principles but his health continued to deteriorate and the project had continued to grow with each further investigation. The outbreak of the
First World War in 1914 prompted him to revise his examinations of the international economy and in 1919 he published
Industry and Trade at the age of 77. This work was a more empirical treatise than the largely theoretical
Principles, and for that reason it failed to attract as much acclaim from theoretical economists. In 1923, he published
Money, Credit, and Commerce, a broad amalgam of previous economic ideas, published and unpublished, stretching back a half-century.
From 1890 to 1924 he was the respected father of the economic profession and to most economists for the half-century after his death, the venerable grandfather. He had shied away from controversy during his life in a way that previous leaders of the profession had not, although his even-handedness drew great respect and even reverence from fellow economists, and his home at Balliol Croft had no shortage of distinguished guests. His students at Cambridge became leading figures in economics, including
John Maynard Keynes and
Arthur Cecil Pigou. His most important legacy was creating a respected, academic, scientifically-founded profession for economists in the future that set the tone of the field for the remainder of the twentieth century.
Having died aged 81 at his home in Cambridge, Marshall is buried in the
Ascension Parish Burial Ground. The library of the Department of Economics at Cambridge University as well as the
University of Bristol Economics department are named for him.
Theoretical contributions
Marshall is considered to be one of the most influential economists of his time, largely shaping mainstream economic thought for the next fifty years. Although his economics was advertised as extensions and refinements of the work of
Adam Smith,
David Ricardo,
Thomas Robert Malthus and
John Stuart Mill, he extended economics away from its classical focus on the market economy and instead popularized it as a study of human behavior. He downplayed the contributions of certain other economists to his work, such as
Leon Walras,
Vilfredo Pareto and
Jules Dupuit, and only grudgingly acknowledged the influence of
William Jevons himself.
Marshall's influence on codifying economic thought is difficult to deny. He popularized the use of
supply and demand functions as tools of price determination (previously discovered independently by
Cournot); modern economists owe the linkage between price shifts and curve shifts to Marshall. Marshall was an important part of the "
marginalist revolution;" the idea that consumers attempt to adjust consumption until
marginal utility equals the price was another of his contributions. The
price elasticity of demand was presented by Marshall as an extension of these ideas. Economic welfare, divided into
producer surplus and
consumer surplus, was contributed by Marshall, and indeed, the two are sometimes described eponymously as '
Marshallian surplus.' He used this idea of surplus to rigorously analyze the effect of taxes and price shifts on market welfare. Marshall also identified
quasi-rents.
Marshall's brief references to the social and cultural relations in the "industrial districts" of
England were used as a starting point for late twentieth-century work in
economic geography and
institutional economics on
clustering and
learning organizations.
