. In Politics, Book II, Part V, he argued that,
Though Aristotle certainly advocated there be many things held in common, he argued that not everything could be, simply because of the "wickedness of human nature". "It is clearly better that property should be private," wrote Aristotle, "but the use of it common; and the special business of the legislator is to create in men this benevolent disposition." In Politics Book I, Aristotle discusses the general nature of households and market exchanges. For him there is a certain "art of acquisition" or "wealth-getting". Money itself has the sole purpose of being a medium of exchange, which means on its own "it is worthless... not useful as a means to any of the necessities of life". Nevertheless, points out Aristotle, because the "instrument" of money is the same many people are obsessed with the simple accumulation of money. "Wealth-getting" for one's household is "necessary and honourable", while exchange on the retail trade for simple accumulation is "justly censured, for it is dishonourable". Aristotle disapproved highly of usury

Bearing many similarities with the modern concept of long run equilibrium a just price was supposed to be one just sufficient to cover the costs of production, including the maintenance of a worker and his family. He argued it was immoral for sellers to raise their prices simply because buyers were in pressing need for a product.

 Scotland, he taught in Oxford, Cologne and Paris. Scotus thought it possible to be more precise than Aquinas in calculating a just price, emphasising the costs of labour and expenses – though he recognised that the latter might be inflated by exaggeration, because buyer and seller usually have different ideas of what a just price comprises. If people did not benefit from a transaction, in Scotus' view, they would not trade. Scotus defended merchants as performing a necessary and useful social role, transporting goods and making them available to the public.

According to Mun, trade was the only way to increase England's treasure (i.e., national wealth) and in pursuit of this end he suggested several courses of action. Important were frugal consumption to increase the amount of goods available for export, increased utilisation of land and other domestic natural resources to reduce import requirements, lowering of export duties on goods produced domestically from foreign materials, and the export of goods with inelastic

He defined property broadly to include people's lives and liberties, as well as their wealth. When people combined their labour with their surroundings, then that created property rights.

Locke was arguing that not only should the government cease interference with people's property (or their "lives, liberties and estates") but also that it should positively work to ensure their protection. His views on price and money were laid out in a letter to a Member of Parliament

Dudley North

Dudley North (1641–1691) was a wealthy merchant and landowner. He worked as an official for the Treasury and was opposed to most mercantile policy. In his Discourses upon trade (1691), which he published anonymously, he argued that the assumption of needing a favourable trade balance was wrong. Trade, he argued, benefits both sides, it promotes specialisation, the division of labour

The circular flow

Similarly disenchanted with regulation on trademarks inspired by mercantilism, a Frenchman name Vincent de Gournay (1712–1759) is reputed to have asked why it was so hard to laissez faire, laissez passer (free enterprise, free trade). He was one of the early physiocrats, a word from Greek meaning "government of nature", who held that agriculture was the source of wealth. As historian David B. Danbom

The invisible hand

"It is not from the benevolence of the butcher, the brewer or the baker, that we expect our dinner, but from their regard to their own self interest. We address ourselves, not to their humanity but to their self-love, and never talk to them of our own necessities but of their advantages."

Smith argued for a "system of natural liberty" where individual effort was the producer of social good.

 of markets. Say argued that there could never be a general deficiency of demand or a general glut of commodities in the whole economy. People produce things, said Say, to fulfill their own wants, rather than those of others. Production is therefore not a question of supply, but an indication of producers demanding goods. Say agreed that a part of the income is saved by the households, but in the long term, savings are invested. Investment and consumption are the two elements of demand, so that production is demand, so it is impossible for production to outrun demand, or for there to be a "general glut" of supply. Say also argued that money was neutral, because its sole role is to facilitate exchanges: therefore, people demand money only to buy commodities. Say said that "money is a veil". To sum up these two ideas, Say said "products are exchanged for products". At most, there will be different economic sectors whose demands are not fulfilled. But over time supplies will shift, businesses will retool for different production and the market will correct itself. An example of a "general glut" could be unemployment, in other words, too great a supply of workers, and too few jobs. Say's Law advocates would suggest that this necessarily means there is an excess demand for other products that will correct itself. This remained a foundation of economic theory until the 1930s.

"The passion between the sexes is necessary and will remain nearly in its present state," he added, meaning that the "power of the population is infinitely greater than the power in the Earth to produce subsistence for man." Nevertheless growth in population is checked by "misery and vice". Any increase in wages for the masses would cause only a temporary growth in population, which given the constraints in the supply of the Earth's produce would lead to misery, vice and a corresponding readjustment to the original population. However more labour could mean more economic growth, either one of which was able to be produced by an accumulation of capital.

. Ricardo's best known work is his Principles of Political Economy and Taxation, which contains his critique of barriers to international trade and a description of the manner the income is distributed in the population. Ricardo made a distinction between the workers, who received a wage fixed to a level at which they can survive, the landowners, who earn a rent, and capitalists, who own capital and receive a profit, a residual part of the income. If population grows, it becomes necessary to cultivate additional land, whose fertility is lower than that of already cultivated fields, because of the law of decreasing productivity. Therefore, the cost of the production of the wheat increases, as well as the price of the wheat: The rents increase also, the wages, indexed to inflation (because they must allow workers to survive) too. Profits decrease, until the capitalists can no longer invest. The economy, Ricardo concluded, is bound to tend towards a steady state.

To postpone the steady state, Ricardo advocates to promote international trade to import wheat at a low price to fight landowners. The Corn Laws
Corn Laws
The Corn Laws were trade barriers designed to protect cereal producers in the United Kingdom of Great Britain and Ireland against competition from less expensive foreign imports between 1815 and 1846.

 in the domestic market. Ricardo argued that raising tariffs, despite being intended to benefit the incomes of farmers, would merely produce a rise in the prices of rents that went into the pockets of landowners. Furthermore, extra labour would be employed leading to an increase in the cost of wages across the board, and therefore reducing exports and profits coming from overseas business. Economics for Ricardo was all about the relationship between the three "factors of production": land

In his fourth book Mill set out a number of possible future outcomes, rather than predicting one in particular.

, should capital accumulate and population increase at the same rate, yet technology stay stable, there would be no change in real wages because supply and demand for labour would be the same. However growing populations would require more land use, increasing food production costs and therefore decreasing profits. The fourth alternative was that technology advanced faster than population and capital stock increased. The result would be a prospering economy. Mill felt the third scenario most likely, and he assumed technology advanced would have to end at some point. But on the prospect of continuing economic growth, Mill was more ambivalent.
Mill is also credited with being the first person to speak of supply and demand as a relationship rather than mere quantities of goods on markets, the concept of opportunity cost

 (1834–1910), again working independently, generalised marginal theory across the economy in Elements of Pure Economics (1874). Small changes in people's preferences, for instance shifting from beef to mushrooms, would lead to a mushroom price rise, and beef price fall. This stimulates producers to shift production, increasing mushrooming investment, which would increase market supply and a new price equilibrium between the products – e.g. lowering the price of mushrooms to a level between the two first levels. For many products across the economy the same would go, if one assumes markets are competitive, people choose on self interest and no cost in shifting production.

, leading to massive rises in unemployment in the United States, leading to debts being recalled from European borrowers, and an economic domino effect across the world. Orthodox economics called for a tightening of spending, until business confidence and profit levels could be restored. Keynes by contrast, had argued in A Tract on Monetary Reform (1923) that a variety of factors determined economic activity, and that it was not enough to wait for the long run market equilibrium to restore itself. As Keynes famously remarked,
On top of the supply of money

There are several ways to define "money," but standard measures usually include currency in circulation and demand deposits .Money supply data are recorded and published, usually...

, Keynes identified the propensity to consume, inducement to invest, the marginal efficiency of capital, liquidity preference and the multiplier effect as variables which determine the level of the economy's output, employment and level of prices.

s, total spending falls. Falling spending leads to reduced incomes and unemployment, which reduces savings again. This continues until the desire to save becomes equal to the desire to invest, which means a new "equilibrium" is reached and the spending decline halts. This new "equilibrium" is a depression, where people are investing less, have less to save and less to spend.

Keynes argued that employment depends on total spending, which is composed of consumer spending and business investment in the private sector
Private sector
In economics, the private sector is that part of the economy, sometimes referred to as the citizen sector, which is run by private individuals or groups, usually as a means of enterprise for profit, and is not controlled by the state...

. Consumers only spend "passively", or according to their income fluctuations. Businesses, on the other hand, are induced to invest by the expected rate of return on new investments (the benefit) and the rate of interest paid (the cost). So, said Keynes, if business expectations remained the same, and government reduces interest rates (the costs of borrowing), investment would increase, and would have a multiplied effect on total spending. Interest rate
Interest rate
An interest rate is the rate at which interest is paid by a borrower for the use of money that they borrow from a lender. For example, a small company borrows capital from a bank to buy new assets for their business, and in return the lender receives interest at a predetermined interest rate for...

s, in turn, depend on the quantity of money and the desire to hold money in bank accounts (as opposed to investing). If not enough money is available to match how much people want to hold, interest rates rise until enough people are put off. So if the quantity of money were increased, while the desire to hold money remained stable, interest rates would fall, leading to increased investment, output and employment. For both these reasons, Keynes therefore advocated low interest rates and easy credit, to combat unemployment.

But Keynes believed in the 1930s, conditions necessitated public sector action. Deficit spending, said Keynes, would kick-start economic activity. This he had advocated in an open letter to U.S. President Franklin D. Roosevelt

 is seldom perfect in a market, an indictment of the theory of markets setting prices. In The Production Function and the Theory of Capital (1953) Robinson tackled what she saw to be some of the circularity in orthodox economics. Neoclassicists assert that a competitive market forces producers to minimise the costs of production. Robinson said that costs of production are merely the prices of inputs, like capital

. Capital goods get their value from the final products. And if the price of the final products determines the price of capital, then it is, argued Robinson, utterly circular to say that the price of capital determines the price of the final products. Goods cannot be priced until the costs of inputs are determined. This would not matter if everything in the economy happened instantaneously, but in the real world, price setting takes time – goods are priced before they are sold. Since capital cannot be adequately valued in independently measurable units, how can one show that capital earns a return equal to the contribution to production? Piero Sraffa

Like Robinson, Sraffa was showing how the major force for price setting in the economy was not necessarily market adjustments.

Milton Friedman

Milton Friedman (1912–2006) stands as one of the most influential economists of the late twentieth century. He won the Nobel Prize in Economics in 1976, among other things, for A Monetary History of the United States (1963). Friedman argued that the Great Depression had been caused by the Federal Reserve's policies through the 1920s, and worsened in the 1930s. Friedman argues laissez-faire government policy is more desirable than government intervention in the economy. Governments should aim for a neutral monetary policy oriented toward long-run economic growth

Macroeconomics since the Bretton Woods era

From the 1970s onwards Friedman's monetarist critique of Keynesian macroeconomics formed the starting point for a number of trends in macroeconomic theory opposed to the idea that government intervention can or should stabilise the economy. Robert Lucas

The standard model for new classical economics is the real business cycle theory

, which sought to explain observed fluctuations in output and employment in terms of real variables such as changes in technology and tastes. Assuming competitive markets, real business cycle theory implied that cyclical fluctuations are optimal responses to variability in technology and tastes, and that macroeconomic stabilisation policies must reduce welfare.

Keynesian economics made a comeback among mainstream economists with the advent of New Keynesian macroeconomics. The central theme of new Keynesianism was the provision of a microeconomic foundation for Keynesian macroeconomics, obtained by identifying minimal deviations from the standard microeconomic assumptions which yield Keynesian macroeconomic conclusions, such as the possibility of significant welfare benefits from macroeconomic stabilization. Akerlof's 'menu costs' arguments, showing that, under imperfect competition, small deviations from rationality generate significant (in welfare terms) price stickiness, are good example of this kind of work.

Economists have combined the methodology of real business cycle theory with theoretical elements, like sticky prices, from new Keynesian theory to produce the new neoclassical synthesis
New neoclassical synthesis
