"permanent-income hypothesis." .

The purpose of this paper is to investigate the evolution of Milton Friedman’s permanent income hypothesis from the 1940s to 1960s, and how it became the paradigm of modern consumption theory. Modelling unobservables, such as permanent income and permanent consumption, is a long-standing issue in economics and econometrics. While the conventional approach has been to set an empirical model to make “permanent income ” measurable, the historical change in the meaning of that theoretical construct is also of methodological interest. This paper will show that the concepts of unobservables, especially permanent income, in Friedman’s work was fluid and depended on the instruments used.

Nice Notes: The permanent income hypothesis

Monetarism’s rise to intellectual prominence began with writings on basic monetary theory by Friedman and other University of Chicago economists during the 1950s, writings that were influential because of their adherence to fundamental neoclassical principles. The most outstanding in this series was Friedman’s presidential address to the American Economic Association in 1967, published in 1968 as “The Role of Monetary Policy.” In this paper Friedman developed the natural-rate hypothesis (which he had clearly stated two years earlier) and used it as a pillar in the argument for a constant-growth-rate rule for monetary policy. Almost simultaneously, , who was not a monetarist, developed a similar no-trade-off theory, and, within a few years, events in the world economy apparently provided dramatic empirical support.

Permanent Income Hypothesis

Like Duisenberg, Milton Friedman and Franco Modigliani argue that consumption function is essentially proportional, i.e., there is no tendency for the proportion of income saved to increase at higher income levels. They, however, believe that households do not adapt the their consumption behavior to their current income alone, but to a general level of their resource over extended period of time. This is called Permanent Income Hypothesis. Modigliani’s theory of consumption, which is called Life Cycle Theory is similar to the permanent Income theory of Friedman.

Similarly, if a strike or a lockout makes him suffer an unexpected loss of income for some time, it’s a negative transitory income that reduces this measured income of the current year below the level of his permanent income. These unforeseen additions to or subtractions from the family income are expected to cancel out over a longer period of time and are thus not relevant to permanent income.

Milton Friedman and the Emergence of the Permanent Income Hypothesis Hsiang-Ke Chao

An economy possesses basic long-run monetary neutrality if an exogenous increase of percent in its stock of money would ultimately be followed, after all adjustments have taken place, by a percent increase in the general price level, with no effects on real variables (e.g., consumption, output, relative prices of individual commodities). While most economists believe that long-run neutrality is a feature of actual market economies, at least approximately, no other group of macroeconomists emphasizes this proposition as strongly as do monetarists. Also, some would object that, in practice, actual central banks almost never conduct policy so as to involve exogenous changes in the . This objection is correct factually but irrelevant: the crucial matter is whether the supply and demand choices of households and businesses reflect concern only for the underlying quantities of goods and services that are consumed and produced. If they do, then the economy will have the property of longrun neutrality, and thus the above-described reaction to a hypothetical change in the money supply would occur. Other neutrality concepts, including the natural-rate hypothesis, are mentioned below.

In the same way measured consumption, i.e., consumption during the current year under study can be divided into two components, viz., permanent consumption and transitory consumption. Any goods purchased because of some exceptionally attractive sale price is a positive transitory consumption and raises the measured consumption above the level of permanent consumption. Similarly, postponement of purchase due to non-availability of goods at present is a negative transitory consumption that reduces measured consumption below the level of permanent consumption.

This is also true in the case of the permanent income hypothesis developed by Milton Friedman

Wage: The payment for the service of a unit of labor, per unit time. In trade theory, it is the only payment to labor, usually unskilled labor. In empirical work, wage data may exclude other compensation, which must be added to get the total cost of employment.
Wage-rental ratio: The ratio of the wage of labor to the rental price of either capital or land, whichever is the other factor in a two-factor Heckscher-Ohlin model. The ratio plays a critical role in this model since it determines the ratios of factors employed in both industries.

Walras' Law: The property of a general equilibrium that if all but one of the markets are in equilibrium, then the remaining market is also in equilibrium, automatically. This follows from the budget constraints of the market participants, and it implies that any one market-clearing condition is redundant and can be ignored.
Walrasian adjustment: A market adjustment mechanism in which price rises when there is excess demand and falls when there is excess supply. Strictly speaking, these excess supplies and demands are those that would obtain without any history of disequilibrium, as with a Walrasian auctioneer.
Walrasian auctioneer: A hypothetical entity that facilitates market adjustment in disequilibrium by announcing prices and collecting information about supply and demand at those prices without any disequilibrium transactions actually taking place.
Warehouse receipt: A receipt issued by a warehouse listing the goods received.
Warehouse-to-warehouse: An insurance policy that covers goods over the entire journey from the seller's to the buyer's premises.

Welfare proposition: In trade theory, this usually refers to any of several gains from trade theorems.
Welfare state: A set of government programs that attempts to provide economic security for the population by providing for people when they are unemployed, ill, or elderly.
Welfare triangle: In a partial equilibrium market diagram, a triangle representing the net welfare benefit or loss from a policy or other change. In trade theory it often means the triangle or triangles representing the deadweight loss due to a tariff.
Welfare: Refers to the economic well being of an individual, group, or economy. For individuals, it is conceptualized by a utility function. For groups, including countries and the world, it is a tricky philosophical concept, since individuals fare differently.

Some of the most useful skills that I do try to give to students are, for example, "walk out of movies if you're not enjoying yourselves." That's what economics tells us to do. But even there, I'm not optimistic that students actually change their lives based on what they're taught. Most people think of education as writing some answers on a test, then getting on with your life and going back to what you were doing before.
