But again, he doesn't get back to his implied recommendation to engage in public works, even if not fully justified from their direct benefits, when he constructs the theory. [80] Keynes proposed a global bank that would issue its own currency—the bancor—which was exchangeable with national currencies at fixed rates of exchange and would become the unit of account between nations, which means it would be used to measure a country's trade deficit or trade surplus. He argued that Keynes regarded the class struggle carelessly, and overlooked the class role of the capitalist state, which he treated as a deus ex machina, and some other points. It is present implicitly in those quantities he expresses in wage units, while being absent from those he expresses in money terms. An intellectual precursor of Keynesian economics was underconsumption theories associated with John Law, Thomas Malthus, the Birmingham School of Thomas Attwood,[8] and the American economists William Trufant Foster and Waddill Catchings, who were influential in the 1920s and 1930s. "[117] This paper examines the future of Keynesian growth theory in terms of its relevance, prospects and likely characteristics. Every country would have an overdraft facility in its bancor account at the International Clearing Union. In the words of Geoffrey Crowther, then editor of The Economist, "If the economic relationships between nations are not, by one means or another, brought fairly close to balance, then there is no set of financial arrangements that can rescue the world from the impoverishing results of chaos. In 1971, Republican US President Richard Nixon even proclaimed "I am now a Keynesian in economics."[91]. [3] Keynesian economics was later redeveloped as New Keynesian economics, becoming part of the contemporary new neoclassical synthesis. Numerous concepts were developed earlier and independently of Keynes by the Stockholm school during the 1930s; these accomplishments were described in a 1937 article, published in response to the 1936 General Theory, sharing the Swedish discoveries. Expansionary fiscal policy consists of increasing net public spending, which the government can effect by a) taxing less, b) spending more, or c) both. Keynesian economic theory says that spending by consumers and the government, investment, and exports will increase the level of output. Failure for them to do so could have serious consequences. Keynesian economics states that in the short-run, especially during recessions, economic output is substantially influenced by aggregate demand (the total spending in the economy). On page 174, Kahn rejects the claim that the effect of public works is at the expense of expenditure elsewhere, admitting that this might arise if the revenue is raised by taxation, but says that other available means have no such consequences. While these are credited to Keynes, others, such as economic historian David Colander, argue that they are, rather, due to the interpretation of Keynes by Abba Lerner in his theory of functional finance, and should instead be called "Lernerian" rather than "Keynesian". Keynesian economics is sometimes referred to as "depression economics," as Keynes's General Theory was written during a time of deep depression not only in his native land of the United Kingdom but worldwide. The classical tradition of partial equilibrium theory had been to split the economy into separate markets, each of whose equilibrium conditions could be stated as a single equation determining a single variable. Its main tools are government spending on infrastructure, unemployment benefits, and education. In his book, The General Theory of Employment, Interest, and Money and other works, Keynes argued against his construction of classical theory, that during recessions business pessimism and certain characteristics of market economies would exacerbate economic weakness and cause aggregate demand to plunge further. In regards to employment, the condition referred to by Keynes as the "first postulate of classical economics" stated that the wage is equal to the marginal product, which is a direct application of the marginalist principles developed during the nineteenth century (see The General Theory). In Keynes's more complicated liquidity preference theory (presented in Chapter 15) the demand for money depends on income as well as on the interest rate and the analysis becomes more complicated. Underconsumptionists were, like Keynes after them, concerned with failure of aggregate demand to attain potential output, calling this "underconsumption" (focusing on the demand side), rather than "overproduction" (which would focus on the supply side), and advocating economic interventionism. It differs significantly from Kahn's paper and even more from Keynes's book. [98], Interpretations of Keynes have emphasized his stress on the international coordination of Keynesian policies, the need for international economic institutions, and the ways in which economic forces could lead to war or could promote peace. If they all have a marginal propensity to consume of 2/3, they will now spend $666.67 on new consumption goods. Keynes believed that the Great Depression seemed to counter this theory. Keynes never fully integrated his second liquidity preference doctrine with the rest of his theory, leaving that to John Hicks: see the IS-LM model below. He argued, "if you have a problem with politicians - criticize politicians," not Keynes. That is, government spending on such things as basic research, public health, education, and infrastructure could help the long-term growth of potential output.

A principal function of central banks in countries that have them is to influence this interest rate through a variety of mechanisms collectively called monetary policy. [17] He interpreted his treatment of liquidity as implying a purely monetary theory of interest. [104][105] The financial crisis of 2007–08, however, has convinced many economists and governments of the need for fiscal interventions and highlighted the difficulty in stimulating economies through monetary policy alone during a liquidity trap. Keynesians emphasized the use of discretionary fiscal policy and monetary policy, while monetarists argued the primacy of monetary policy, and that it should be rules-based. It was characterized by explicit and rigorous adherence to microfoundations, as well as use of increasingly sophisticated mathematical modelling. But, to these schools, there was no reason to believe that this stimulation would outrun the side-effects that "crowd out" private investment: first, it would increase the demand for labour and raise wages, hurting profitability; Second, a government deficit increases the stock of government bonds, reducing their market price and encouraging high interest rates, making it more expensive for business to finance fixed investment. Keynesians emphasized the dependence of consumption on disposable income and, also, of investment on current profits and current cash flow. [62] Kahn's multiplier has consequently been understood by much of the Keynesian literature as playing a major role in Keynes's own theory, an interpretation encouraged by the difficulty of understanding Keynes's presentation.
