Keynesian economics are the various macroeconomic theories and models of how aggregate demand strongly influences economic output and inflation. In the Keynesian view, aggregate demand does not necessarily equal the productive capacity of the economy. It is influenced by a host of factors that sometimes behave erratically and impact production, employment, and inflation.
John Maynard Keynes, 1st Baron Keynes, was an English economist and philosopher whose ideas fundamentally changed the theory and practice of macroeconomics and the economic policies of governments. Originally trained in mathematics, he built on and greatly refined earlier work on the causes of business cycles. One of the most influential economists of the 20th century, he produced writings that are the basis for the school of thought known as Keynesian economics, and its various offshoots. His ideas, reformulated as New Keynesianism, are fundamental to mainstream macroeconomics. He is known as the "father of macroeconomics".
George Arthur Akerlof is an American economist and a university professor at the McCourt School of Public Policy at Georgetown University and Koshland Professor of Economics Emeritus at the University of California, Berkeley. Akerlof was awarded the 2001 Nobel Memorial Prize in Economic Sciences, jointly with Michael Spence and Joseph Stiglitz, "for their analyses of markets with asymmetric information." He is the husband of United States Secretary of the Treasury Janet Yellen.
The General Theory of Employment, Interest and Money is a book by English economist John Maynard Keynes published in February 1936. It caused a profound shift in economic thought, giving macroeconomics a central place in economic theory and contributing much of its terminology – the "Keynesian Revolution". It had equally powerful consequences in economic policy, being interpreted as providing theoretical support for government spending in general, and for budgetary deficits, monetary intervention and counter-cyclical policies in particular. It is pervaded with an air of mistrust for the rationality of free-market decision making.
In classical economics, Say's law, or the law of markets, is the claim that the production of a product creates demand for another product by providing something of value which can be exchanged for that other product. So, production is the source of demand. In his principal work, A Treatise on Political Economy, Jean-Baptiste Say wrote: "A product is no sooner created, than it, from that instant, affords a market for other products to the full extent of its own value." And also, "As each of us can only purchase the productions of others with his/her own productions – as the value we can buy is equal to the value we can produce, the more men can produce, the more they will purchase."
Underconsumption is a theory in economics that recessions and stagnation arise from an inadequate consumer demand, relative to the amount produced. In other words, there is a problem of overproduction and overinvestment during a demand crisis. The theory formed the basis for the development of Keynesian economics and the theory of aggregate demand after the 1930s.
In economics, money illusion, or price illusion, is a cognitive bias where money is thought of in nominal, rather than real terms. In other words, the face value of money is mistaken for its purchasing power at a previous point in time. Viewing purchasing power as measured by the nominal value is false, as modern fiat currencies have no intrinsic value and their real value depends purely on the price level. The term was coined by Irving Fisher in Stabilizing the Dollar. It was popularized by John Maynard Keynes in the early twentieth century, and Irving Fisher wrote an important book on the subject, The Money Illusion, in 1928.
The history of economic thought is the study of the philosophies of the different thinkers and theories in the subjects that later became political economy and economics, from the ancient world to the present day.

Animal spirits or animal spirit may refer to:
The neoclassical synthesis (NCS), or neoclassical–Keynesian synthesis is an academic movement and paradigm in economics that worked towards reconciling the macroeconomic thought of John Maynard Keynes in his book The General Theory of Employment, Interest and Money (1936) with neoclassical economics.
Following the global 2007–2008 financial crisis, there was a worldwide resurgence of interest in Keynesian economics among prominent economists and policy makers. This included discussions and implementation of economic policies in accordance with the recommendations made by John Maynard Keynes in response to the Great Depression of the 1930s, most especially fiscal stimulus and expansionary monetary policy.
The Keynesian Revolution was a fundamental reworking of economic theory concerning the factors determining employment levels in the overall economy. The revolution was set against the then orthodox economic framework, namely neoclassical economics.
Animal spirits is a term used by John Maynard Keynes in his 1936 book The General Theory of Employment, Interest and Money to describe the instincts, proclivities and emotions that seemingly influence human behavior, which can be measured in terms of consumer confidence.
Macroeconomic theory has its origins in the study of business cycles and monetary theory. In general, early theorists believed monetary factors could not affect real factors such as real output. John Maynard Keynes attacked some of these "classical" theories and produced a general theory that described the whole economy in terms of aggregates rather than individual, microeconomic parts. Attempting to explain unemployment and recessions, he noticed the tendency for people and businesses to hoard cash and avoid investment during a recession. He argued that this invalidated the assumptions of classical economists who thought that markets always clear, leaving no surplus of goods and no willing labor left idle.
Keynes: The Return of the Master is a 2009 book by economic historian Robert Skidelsky. The work discusses the economic theories and philosophy of John Maynard Keynes, and argues about their relevance to the world following the Financial crisis of 2007–2010. In contrast to the 30 years he needed to write his prize-winning biography on Keynes, the author was able to write this 240-page book in only three months.
Fear the Boom and Bust is a 2010 hip hop music video in which 20th century economists John Maynard Keynes and Friedrich von Hayek take part in a rap battle discussing economics, specifically, the boom and bust business cycle, for which the video is named. The video has more than seven million views on YouTube.
The term kaleidics denotes the ever-changing shape and status of an economy. Uncertainty is the primary kaleidic factor. It is strongly associated with the work of George Shackle, who had a rather radical interpretation of Keynesian economic theory. He surmised that the uncertainty in a capitalist economy was due to the irrational nature of investment, which is often driven by irrational fears, rumors, and superstition, rather than what is traditionally assumed to be cold, hard, calculation. Such theories lead to the view, expressed in Viennese kaleidics, that the turbulence of markets cannot be smoothed through government interference, and must therefore be left to their own devices.
The Return of Depression Economics and the Crisis of 2008 is a non-fiction book by American economist and Nobel Prize winner Paul Krugman, written in response to growing socio-political discourse on the return of economic conditions similar to The Great Depression. The book was first published in 1999 and later updated in 2008 following his Nobel Prize of Economics. The Return of Depression Economics uses Keynesian analysis of past economics crisis, drawing parallels between the 2008 financial crisis and the Great Depression. Krugman challenges orthodox economic notions of restricted government spending, deregulation of markets and the efficient market hypothesis. Krugman offers policy recommendations for the prevention of future financial crises and suggests that policymakers "relearn the lessons our grandfathers were taught by the Great Depression" and prop up spending and enable broader access to credit.
Keynes's theory of wages and prices is contained in the three chapters 19-21 comprising Book V of The General Theory of Employment, Interest and Money. Keynes, contrary to the mainstream economists of his time, argued that capitalist economies were not inherently self-correcting. Wages and prices were "sticky", in that they were not flexible enough to respond efficiently to market demand. An economic depression for instance, would not necessarily set off a chain of events leading back to full employment and higher wages. Keynes believed that government action was necessary for the economy to recover.
