Veil of money

Last updated

The veil of money is the property assumed by some economists whereby money is a commodity like other commodities – such as oil or gold or food – as opposed to its having special properties. [1]

Money Object or record accepted as payment

Money is any item or verifiable record that is generally accepted as payment for goods and services and repayment of debts, such as taxes, in a particular country or socio-economic context. The main functions of money are distinguished as: a medium of exchange, a unit of account, a store of value and sometimes, a standard of deferred payment. Any item or verifiable record that fulfils these functions can be considered as money.

Commodity marketable item produced to satisfy wants or needs

In economics, a commodity is an economic good or service that has full or substantial fungibility: that is, the market treats instances of the good as equivalent or nearly so with no regard to who produced them. Most commodities are raw materials, basic resources, agricultural, or mining products, such as iron ore, sugar, or grains like rice and wheat. Commodities can also be mass-produced unspecialized products such as chemicals and computer memory.

This question arises in classical political economy, where John Stuart Mill argues that money is unimportant, and that while money might disguise the true values in an economy, it would only do so for a limited period of time.[ citation needed ] This was used to argue against government intervention in political economy as a waste of time. The problem expanded, however, as money swung back toward credit-based issuance of notes. What money meant, or was equivalent to, became important as governments attempted to adjust interest rates rather than maintain the gold standard.

John Stuart Mill British philosopher and political economist

John Stuart Mill, usually cited as J. S. Mill, was a British philosopher, political economist, and civil servant. One of the most influential thinkers in the history of classical liberalism, he contributed widely to social theory, political theory, and political economy. Dubbed "the most influential English-speaking philosopher of the nineteenth century", Mill's conception of liberty justified the freedom of the individual in opposition to unlimited state and social control.

Gold standard monetary system in which the standard economic unit of account is based on a fixed quantity of gold

A gold standard is a monetary system in which the standard economic unit of account is based on a fixed quantity of gold. Three types can be distinguished: specie, bullion, and exchange.

In the 20th century the veil of money was used to describe questions of stability and the exchangeability of money for interest or commodity in a macroeconomic model. In essence, as long as money can be treated like a commodity, there is no stickiness between money and goods, or money and interest.

Macroeconomics is a branch of economics dealing with the performance, structure, behavior, and decision-making of an economy as a whole. This includes regional, national, and global economies. Macroeconomists study aggregated indicators such as GDP, unemployment rates, national income, price indices, and the interrelations among the different sectors of the economy to better understand how the whole economy functions. They also develop models that explain the relationship between such factors as national income, output, consumption, unemployment, inflation, saving, investment, international trade, and international finance.

The veil of money and, as a related issue, the quantity theory of money have special importance in economic theory throughout the 20th century. Actually, 20th century economics can be interpreted as a sequence of theoretical answers to the question whether money is only a veil or not. Different theories can be judged by their implied ideas as to the neutrality of money. In the simplest models and in the simplest form of the quantity theory of money, money is completely neutral, that is, changes in the money supply do not affect anything real. However, in the more elaborated models the neutrality theorem was applied rather to long-run considerations. For both Milton Friedman and Robert E. Lucas money was not a mere veil in the short run, so money was assumed to have real effects in the short run. The mechanisms through which money could exert these real effects were radically different and so were the sets of assumptions these authors created to establish their models. For example, Friedman postulated adaptive expectations, while Lucas assumed his economic agents to be able to form rational expectations. For both of them, money was only neutral in the long-run – that is, money was not just a veil in the short-run – but the scope of countercyclical economic policy was radically curtailed in new classical macroeconomics. In the case of rational expectations the monetary authority is not able to carry out systematic countercyclical economic policy – that is, it cannot exploit the existing short-run Phillips curve. However, it can be realized that if any of the conditions necessary to the ineffectiveness of systematic economic policy is not met, economic policy can be effective again, so, money is not only a veil. [2]

In monetary economics, the quantity theory of money (QTM) states that the general price level of goods and services is directly proportional to the amount of money in circulation, or money supply.

Neutrality of money is the idea that a change in the stock of money affects only nominal variables in the economy such as prices, wages, and exchange rates, with no effect on real variables, like employment, real GDP, and real consumption. Neutrality of money is an important idea in classical economics and is related to the classical dichotomy. It implies that the central bank does not affect the real economy by creating money. Instead, any increase in the supply of money would be offset by a proportional rise in prices and wages. This assumption underlies some mainstream macroeconomic models. Others like monetarism view money as being neutral only in the long-run.

Milton Friedman American economist, statistician, and writer

Milton Friedman was an American economist who received the 1976 Nobel Memorial Prize in Economic Sciences for his research on consumption analysis, monetary history and theory and the complexity of stabilization policy. With George Stigler and others, Friedman was among the intellectual leaders of the second generation of Chicago price theory, a methodological movement at the University of Chicago's Department of Economics, Law School and Graduate School of Business from the 1940s onward. Several students and young professors who were recruited or mentored by Friedman at Chicago went on to become leading economists, including Gary Becker, Robert Fogel, Thomas Sowell and Robert Lucas Jr.

In economics, money illusion, or price illusion, is the tendency of people to think of currency 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.

In economics, a real value, of a good or other entity, is one which has been adjusted for inflation, enabling comparison of quantities as if prices had not changed. Changes in real terms therefore exclude the effect of inflation. In contrast with a real value, a nominal value has not been adjusted for inflation, and so changes in nominal value reflect at least in part the effect of inflation.

In economics, adaptive expectations is a hypothesized process by which people form their expectations about what will happen in the future based on what has happened in the past. For example, if inflation has been higher than expected in the past, people would revise expectations for the future.

In economics, "rational expectations" are model-consistent expectations, in that agents inside the model are assumed to "know the model" and on average take the model's predictions as valid. Rational expectations ensure internal consistency in models involving uncertainty. To obtain consistency within a model, the predictions of future values of economically relevant variables from the model are assumed to be the same as that of the decision-makers in the model, given their information set, the nature of the random processes involved, and model structure. The rational expectations assumption is used especially in many contemporary macroeconomic models.

New Keynesian economics is a school of contemporary macroeconomics that strives to provide microeconomic foundations for Keynesian economics. It developed partly as a response to criticisms of Keynesian macroeconomics by adherents of new classical macroeconomics.

Robert Emerson Lucas Jr. is an American economist at the University of Chicago, where he is currently the John Dewey Distinguished Service Professor Emeritus in Economics and the College. Widely regarded as the central figure in the development of the new classical approach to macroeconomics, he received the Nobel Prize in Economics in 1995 "for having developed and applied the hypothesis of rational expectations, and thereby having transformed macroeconomic analysis and deepened our understanding of economic policy". He has been characterized by N. Gregory Mankiw as "the most influential macroeconomist of the last quarter of the 20th century."

The Phillips curve is a single-equation econometric model, named after William Phillips, describing a historical inverse relationship between rates of unemployment and corresponding rates of rises in wages that result within an economy. Stated simply, decreased unemployment, in an economy will correlate with higher rates of wage rises. Phillips did not himself state there was any relationship between employment and inflation, this notion was a trivial deduction from his statistical findings. Samuelson and Solow made the connection explicit and subsequently Milton Friedman and Edmund Phelps put the theoretical structure in place. In so doing, Friedman was to successfully predict the imminent collapse of Phillips' a-theoretic correlation.

The Ricardian equivalence proposition is an economic hypothesis holding that consumers are forward looking and so internalize the government's budget constraint when making their consumption decisions. This leads to the result that, for a given pattern of government spending, the method of financing that spending does not affect agents' consumption decisions, and thus, it does not change aggregate demand.

Neo-Keynesian economics is a school of macroeconomic thought that was developed in the post-war period from the writings of John Maynard Keynes. A group of economists, attempted to interpret and formalize Keynes' writings and to synthesize it with the neo-classical models of economics. Their work has become known as the neo-classical synthesis and created the models that formed the core ideas of neo-Keynesian economics. These ideas dominated mainstream economics in the post-war period and formed the mainstream of macroeconomic thought in the 1950s, 1960s and 1970s.

Robert Joseph Barro is an American macroeconomist and the Paul M. Warburg Professor of Economics at Harvard University. The Research Papers in Economics project ranked him as the fifth most influential economist in the world, as of March 2016, based on his academic contributions. Barro is considered one of the founders of new classical macroeconomics, along with Robert Lucas, Jr. and Thomas J. Sargent. He is currently a senior fellow at Stanford University's Hoover Institution and co-editor of the Quarterly Journal of Economics, the top journal in economics in terms of its impact factor.

Thomas J. Sargent American economist

Thomas John "Tom" Sargent is an American economist, who is currently the W.R. Berkley Professor of Economics and Business at New York University. He specializes in the fields of macroeconomics, monetary economics and time series econometrics. As of 2014, he ranks fourteenth among the most cited economists in the world. He was awarded the Nobel Memorial Prize in Economics in 2011 together with Christopher A. Sims for their "empirical research on cause and effect in the macroeconomy".

The policy-ineffectiveness proposition (PIP) is a new classical theory proposed in 1975 by Thomas J. Sargent and Neil Wallace based upon the theory of rational expectations, which posits that monetary policy cannot systematically manage the levels of output and employment in the economy.

In macroeconomics, the classical dichotomy is the idea, attributed to classical and pre-Keynesian economics, that real and nominal variables can be analyzed separately. To be precise, an economy exhibits the classical dichotomy if real variables such as output and real interest rates can be completely analyzed without considering what is happening to their nominal counterparts, the money value of output and the interest rate. In particular, this means that real GDP and other real variables can be determined without knowing the level of the nominal money supply or the rate of inflation. An economy exhibits the classical dichotomy if money is neutral, affecting only the price level, not real variables.

The permanent income hypothesis (PIH) is an economic theory attempting to describe how agents spread consumption over their lifetimes. First developed by Milton Friedman, it supposes that a person's consumption at a point in time is determined not just by their current income but also by their expected income in future years—their "permanent income". In its simplest form, the hypothesis states that changes in permanent income, rather than changes in temporary income, are what drive the changes in a consumer's consumption patterns. Its predictions of consumption smoothing, where people spread out transitory changes in income over time, depart from the traditional Keynesian emphasis on the marginal propensity to consume. It has had a profound effect on the study of consumer behavior, and provides an explanation for some of the failures of Keynesian demand management techniques.

The Lucas islands model is an economic model of the link between money supply and price and output changes in a simplified economy using rational expectations. It delivered a new classical explanation of the Phillips curve relationship between unemployment and inflation. The model was formulated by Robert Lucas, Jr. in a series of papers in the 1970s.

New classical macroeconomics, sometimes simply called new classical economics, is a school of thought in macroeconomics that builds its analysis entirely on a neoclassical framework. Specifically, it emphasizes the importance of rigorous foundations based on microeconomics, especially rational expectations.

History of macroeconomic thought

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.

Neil Wallace is an American economist and professor at Pennsylvania State University. Wallace is considered one of the main proponents of new classical macroeconomics.

The Lucas aggregate supply function or Lucas "surprise" supply function, based on the Lucas imperfect information model, is a representation of aggregate supply based on the work of new classical economist Robert Lucas. The model states that economic output is a function of money or price "surprise". The model accounts for the empirically based trade off between output and prices represented by the Phillips curve, but the function breaks from the Phillips curve since only unanticipated price level changes lead to changes in output. The model accounts for empirically observed short-run correlations between output and prices, but maintains the neutrality of money in the long-run. The policy ineffectiveness proposition extends the model by arguing that, since people with rational expectations cannot be systematically surprised by monetary policy, monetary policy cannot be used to systematically influence the economy.
