Wage-price Spiral
In macroeconomics, a wage-price spiral (also called a wage/price spiral or price/wage spiral) is a proposed explanation for inflation, in which wage increases cause price increases which in turn cause wage increases, in a positive feedback loop. Greg Mankiw writes, "At some point, this spiral of ever-rising wages and prices will slow... In the long run, the economy returns to he pointwhere the aggregate-demand curve crosses the long-run aggregate-supply curve." History An early use of the concept was in 1868. The term "wage-price spiral" appeared in a 1937 ''New York Times'' article about a steel-workers' strike. In the 1970s, US President Richard Nixon attempted to break what he saw as a "spiral" of prices and costs, by imposing a price freeze, with little effect. Some sources distinguish between wage-price spirals and price-wage spirals. According to Daniel J.B. Mitchell and Christopher L. Erickson, the concept fell out of favor with the decline of unions and collective bargai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflation
In economics, inflation is an increase in the general price level of goods and services in an economy. When the general price level rises, each unit of currency buys fewer goods and services; consequently, inflation corresponds to a reduction in the purchasing power of money. The opposite of inflation is deflation, a sustained decrease in the general price level of goods and services. The common measure of inflation is the inflation rate, the annualized percentage change in a general price index. As prices do not all increase at the same rate, the consumer price index (CPI) is often used for this purpose. The employment cost index is also used for wages in the United States. Most economists agree that high levels of inflation as well as hyperinflation—which have severely disruptive effects on the real economy—are caused by persistent excessive growth in the money supply. Views on low to moderate rates of inflation are more varied. Low or moderate inflation may be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Positive Feedback
Positive feedback (exacerbating feedback, self-reinforcing feedback) is a process that occurs in a feedback loop which exacerbates the effects of a small disturbance. That is, the effects of a perturbation on a system include an increase in the magnitude of the perturbation. That is, ''A produces more of B which in turn produces more of A''.Keesing, R.M. (1981). Cultural anthropology: A contemporary perspective (2nd ed.) p.149. Sydney: Holt, Rinehard & Winston, Inc. In contrast, a system in which the results of a change act to reduce or counteract it has negative feedback. Both concepts play an important role in science and engineering, including biology, chemistry, and cybernetics. Mathematically, positive feedback is defined as a positive loop gain around a closed loop of cause and effect. That is, positive feedback is in phase with the input, in the sense that it adds to make the input larger. Positive feedback tends to cause system instability. When the loop gain is pos ...

Rational Expectations
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. Since most macroeconomic models today study decisions under uncertainty and over many periods, the expectations of individuals, firms, and government institutions about future economic conditions are an essential part of the model. To assume rational expectations is to assume that agents' expectations may be wrong, but are corr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Socialist Worker
''Socialist Worker'' is the name of several far-left newspapers currently or formerly associated with the International Socialist Tendency (IST). It is a weekly newspaper published by the Socialist Workers Party (SWP) in the United Kingdom since 1968, and a monthly published by the International Socialists in Canada. It was a monthly (and daily web site) published by the International Socialist Organization (ISO) in the United States from 1977–2019, and a biweekly published by the Socialist Workers Party in Ireland, a quarterly published by the International Socialist Organisation in Zimbabwe and a monthly published by the former International Socialist Organisation in Australia. Socialist Worker was also the name of an IST political group in New Zealand. United Kingdom Although ''Socialist Worker'' sales/circulation data is not publicly available, John Molyneux estimated the circulation of the paper in 2006 to be under 8,000. Special "bumper" issues have a circulation a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tribune (magazine)
''Tribune'' is a democratic socialist political magazine founded in 1937 and published in London, initially as a newspaper, then converting to a magazine in 2001. While it is independent, it has usually supported the Labour Party from the left. From 2008 it faced serious financial difficulties until it was purchased by '' Jacobin'' in late 2018, shifting to a quarterly publication model. Since its relaunch the number of paying subscribers has passed 15,000, with columns from high-profile socialist politicians such as former leader of the Labour Party Jeremy Corbyn, former Second Deputy Prime Minister of Spain Pablo Iglesias and former Bolivian President Evo Morales. In January 2020, it was used as the platform on which Rebecca Long-Bailey chose to launch her Labour leadership campaign. History Origins ''Tribune'' was founded in early 1937 by two wealthy left-wing Labour Party Members of Parliament (MPs), Sir Stafford Cripps and George Strauss, to back the Unity Campai ...

Milton Friedman
Milton Friedman (; July 31, 1912 – November 16, 2006) was an American economist and statistician 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 Chicago school of economics, a neoclassical school of economic thought associated with the work of the faculty at the University of Chicago that rejected Keynesianism in favor of monetarism until the mid-1970s, when it turned to new classical macroeconomics heavily based on the concept of rational expectations. Several students, young professors and academics 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. Friedman's challenges to what he called "naive Keynesian theory" began with his interpretat ...

Demand-pull Inflation
Demand-pull inflation is asserted to arise when aggregate demand in an economy is more than aggregate supply. It involves inflation rising as real gross domestic product rises and unemployment falls, as the economy moves along the Phillips curve. This is commonly described as "too much money chasing too few goods". More accurately, it should be described as involving "too much money spent chasing too few goods", since only money that is spent on goods and services can cause inflation. This would not be expected to happen, unless the economy is already at a full employment level. It is the opposite of cost-push inflation. How it happens In Keynesian theory, increased employment results in increased aggregate demand (AD), which leads to further hiring by firms to increase output. Due to capacity constraints, this increase in output will eventually become so small that the price of the good will rise. At first, unemployment will go down, shifting AD1 to AD2, which increases ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Built-in Inflation
Built-in inflation is a type of inflation that results from past events and persists in the present. Built-in inflation is one of three major determinants of the current inflation rate. In Robert J. Gordon's triangle model of inflation, the current inflation rate equals the sum of demand-pull inflation, cost-push inflation, and built-in inflation. "Demand-pull inflation" refers to the effects of falling unemployment rates (rising real gross domestic product) in the Phillips curve model, while the other two factors lead to ''shifts'' in the Phillips curve. The built-in inflation originates from either persistent demand-pull or large cost-push (supply-shock) inflation in the past. It then becomes a "normal" aspect of the economy, via inflationary expectations and the price/wage spiral. *Inflationary expectations play a role because if workers and employers expect inflation to persist in the future, they will increase their (nominal) wages and prices now. (See real vs. nominal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triangle Model
A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices ''A'', ''B'', and ''C'' is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane (i.e. a two-dimensional Euclidean space). In other words, there is only one plane that contains that triangle, and every triangle is contained in some plane. If the entire geometry is only the Euclidean plane, there is only one plane and all triangles are contained in it; however, in higher-dimensional Euclidean spaces, this is no longer true. This article is about triangles in Euclidean geometry, and in particular, the Euclidean plane, except where otherwise noted. Types of triangle The terminology for categorizing triangles is more than two thousand years old, having been defined on the very first page of Euclid's Elements. The names used for modern classification are eit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
