Definition Of Economics By David Ricardo
Mireille Kreines
Ricardo was born in London as the third surviving child of a successful stockbroker and his wife. He came from a Sephardic Jewish family of Portuguese origin. At 21, he eloped with a Quaker and converted to Unitarianism, causing estrangement from his family. He made his fortune financing government borrowing and later retired to an estate in Gloucestershire. Ricardo served as High Sheriff of Gloucestershire and bought a seat in Parliament as an earnest reformer. He was friends with prominent figures like James Mill, Jeremy Bentham, and Thomas Malthus, engaging in debates over various topics. Ricardo was also a member of The Geological Society, and his youngest sister was an author.
As MP for Portarlington, Ricardo advocated for liberal political movements and reforms, including free trade, parliamentary reform, and criminal law reform. He believed free trade increased the well-being of people by making goods more affordable. Ricardo notably opposed the Corn Laws, which he saw as barriers to economic growth. His friend John Louis Mallett described Ricardo's conviction in his beliefs, though he expressed doubts about Ricardo's disregard for experience and practice. Ricardo died at 51 from an ear infection that led to septicaemia (sepsis). He left behind a considerable fortune and a lasting legacy, with his free trade views eventually becoming public policy in Britain.
Ricardo wrote his first economics article at age 37, advocating for a reduction in the note-issuing of the Bank of England. He was also an abolitionist and believed in the autonomy of a central bank as the issuer of money. Ricardo worked on fixing issues in Adam Smith's Labour Theory of Value, stating that the value of a commodity depends on the labour necessary for its production. He contributed to the development of theories of rent, wages, and profits, defining rent as the difference between the produce obtained by employing equal quantities of capital and labour. Ricardo's Theory of Profit posited that as real wages increase, real profits decrease due to the revenue split between profits and wages.
Ricardian theory of international trade challenges the mercantilism concept of accumulating gold or silver by promoting industry specialization and free trade. Ricardo introduced the concept of "comparative advantage," suggesting that nations should concentrate resources only in industries where they have the greatest efficiency of production relative to their own alternative uses of resources. He argued that international trade is always beneficial, even if one country is more competitive in every area than its trading counterpart. Ricardo opposed protectionism for national economies and was concerned about the short-term impact of technological change on labour.
Following this estrangement he went into business for himself with the support of Lubbocks and Forster, an eminent banking house. He made the bulk of his fortune by profitably financing Government borrowing. There is a story that he made his fortune as a result of speculation on the outcome of the Battle of Waterloo: The Sunday Times reported in Ricardo's obituary, published on 14 September 1823, that during the battle Ricardo "netted upwards of a million sterling", a huge sum at the time, and this was later popularised by the economist Paul Samuelson; in reality Ricardo was already very rich and in June 1815 sold his latest government stock before the result of the battle was known in London, so missing half of the rise.[11]
Ricardo was a close friend of James Mill. Other notable friends included Jeremy Bentham and Thomas Malthus, with whom Ricardo had a considerable debate (in correspondence) over such things as the role of landowners in a society. He also was a member of Malthus' Political Economy Club, and a member of the King of Clubs. He was one of the original members of The Geological Society.[10] His youngest sister was author Sarah Ricardo-Porter (e.g., Conversations in Arithmetic).
As MP for Portarlington, Ricardo voted with the opposition in support of liberal political movements in Naples and Sicily, and for inquiry into the administration of justice in Tobago. He divided for (voted for) repeal of the Blasphemous and Seditious Libels Act; then for inquiry into the Peterloo massacre; and, in 1821, for abolition of the death penalty for forgery.
He adamantly supported free trade. In 1821 he voted against renewal of the sugar duties, and objected to the higher duty on East Indian as opposed to West Indian produce. He opposed the timber duties. He voted silently for parliamentary reform and in 1822 spoke in its favour at the Westminster anniversary reform dinner; and again voted for criminal law reform.
Ricardo believed that increasing imports by free trade boosted the wellbeing of mankind by increasing the amount of goods cheaply available for subsistence and consumption. He was said to have "possessed an extraordinary quickness in perceiving in the turns of the market any accidental difference which might arise between the relative price of different stocks".[14] And he grew his wealth dealing in securities during the Revolutionary and Napoleonic wars.
Political reform was needed as agricultural output was struggling to keep pace with population growth. The Corn Laws imposed barriers to imports that increased subsistence/consumption costs and triggered demand for higher wages. Higher wages reduced profits for agricultural producers, and had the immediate effects of reducing capital investments and slowing the growth of a nation's economy. Rising rents, attributed by Ricardo to the Corn Laws, came at the expense of the economic profits of nations. For David Ricardo, free trade was ever the answer; he envisioned Britain as importing agriculture products in exchange for exporting manufactured goods.[16] Eventually, after his death, the interventionist laws were repealed, and his free trade views became public policy in Britain.[17]
Ricardo wrote his first economics article at 37, firstly in The Morning Chronicle advocating reduction in the note-issuing of the Bank of England and then publishing The High Price of Bullion, a Proof of the Depreciation of Bank Notes in 1810.[19][20]
Adam Smith argued that free commercial banking, such as the banking system in Scotland which had no central bank when Wealth of Nations was written in 1776, was favourable to economic growth. Writing just a few decades later, Ricardo argued for a central bank, a cause that was taken up by his students, including John Stuart Mill, who was known to favour the laissez-faire policies in every place but banking.
The public, or the Government on behalf of the public, is indebted to the Bank in a sum of money larger than the whole amount of Bank notes in circulation; for the Government not only owes the Bank fifteen million, its original capital, which is lent at 3 per cent. interest, but also many more millions which are advanced on Exchequer bills, on half-pay and pension annuities, and on other securities. It is evident, therefore, that if the Government itself were to be the sole issuer of paper money instead of borrowing it of the Bank, the only difference would be with respect to the interest: the Bank would no longer receive interest and the Government would no longer pay it; but all other classes in the community would be exactly in the same position in which they now stand.
The value of a commodity, or the quantity of any other commodity for which it will exchange, depends on the relative quantity of labour which is necessary for its production, and not on the greater or less compensation which is paid for that labour.
Ricardo contributed to the development of theories of rent, wages, and profits. He defined rent as "the difference between the produce obtained by the employment of two equal quantities of capital and labour."[30] Ricardo believed that the process of economic development, which increased land use and eventually led to the cultivation of poorer land, principally benefited landowners. According to Ricardo, such premium over "real social value" that is reaped due to ownership constitutes value to an individual but is at best[31] a paper monetary return to "society". The portion of such purely individual benefit that accrues to scarce resources Ricardo labels "rent".
In particular, Ricardo postulates that rent is a result of increased populations which results in assets growing scarce and in some cases diminished returns of which were once abundant. Ricardo breaks down this premise by first supposing there are three fields of land - No. 1, 2, 3, - to yield corn, with an equal employment of capital and labour. Initially land No.1 is cultivated and is very productive as measured through the abundant surplus. Over time this abundant surplus becomes diminished as the result of an increase in population, which subsequently creates an increased demand for food. The less desired land, No.2, must now be cultivated and eventually so must land No.3 and so on and so forth. For Ricardo each new cultivated results in diminished surplus as the quality of land fails to yield the equal of that before it. In light of such diminishing surplus landowners see opportunities to charge rent as a means to compensate for the loss of returns on output.[30]
In his Theory of Profit, Ricardo stated that as real wages increase, real profits decrease because the revenue from the sale of manufactured goods is split between profits and wages. He said in his Essay on Profits, "Profits depend on high or low wages, wages on the price of necessaries, and the price of necessaries chiefly on the price of food."
Between 1500 and 1750 most economists advocated mercantilism, which promoted the idea of international trade for the purpose of earning bullion by running a trade surplus with other countries. Ricardo challenged the idea that the purpose of trade was merely to accumulate gold or silver. With "comparative advantage" Ricardo argued in favour of industry specialisation and free trade. He suggested that industry specialization combined with free international trade always produces positive results. This theory expanded on the concept of absolute advantage.
