lucas critique phillips curve

Prices in technology driven economy, with automatization and free information, available to the suppliers as well as to the consumers, have the propensity to reach marginal cost, which by itself have tendency to become zero or close to zero, after the initial investment was done, and the technology became available to all.In an economy with full automatization, mobility and information, with relatively abundant capital for investments, only new inventions and innovations, that produce temporary state of monopoly, can still generate profit, before the new invention will become a general public knowledge, and allow price well above marginal cost of the product.

Does it mean that monetary easing has no influence on prices? The Phillips curve and the Lucas critique: Some historical evidence (Discussion paper / Centre for Economic Policy Research) [George Alogoskoufis] on Amazon.com. ), lots of people are starting to wonder if we might be headed for a pick-up in the rate of inflation, which has been averaging well under 2% a year since the financial crisis of September 2008 ushered in the Little … Over the years, I have become increasingly impressed by the similarities between my approach and that of R. G. Hawtrey and hope to bring Hawtrey's unduly neglected contributions to the attention of a wider audience. I am not a big admirer of the Lucas Critique for reasons that I have discussed in other posts (e.g., If there is a demonstrable correlation between the level of employment and inflation, how would you rationalize this relationship? Re-evaluate what constitutes and contributes to domestic inflation and you can solve the problem rather that using and manipulating external factors (patchwork) to resolve an endemic disease.Henry, The original Phillips Curve was a plot of points representing combinations of the rate of unemployment and the rate of increase in wages published in an article in the late 1950s by a distinguished economist at the London School of Economics, A. W. Phillips. Then came the sudden stop after the Greek crisis, which sent unemployment soaring.Meanwhile, the pre-crisis era was marked by relatively high inflation, well above the euro-area average; the post-crisis era by near-zero inflation, below the rest of the euro area, allowing Spain to achieve (at immense cost) an “internal devaluation” that has driven an export-led recovery.So, do you really want to claim that the swings in inflation had nothing to do with the swings in unemployment? If nominal wages are sticky downward, the countries with falling prices will be the ones having rising unemployment.’This has nothing to do with the Phillips curve but nevertheless it seems correct to link inflation and employment in these circumstances.Fill in your details below or click an icon to log in:I am an economist in the Washington DC area.

In my book Free Banking and Monetary Reform, I argued for a non-Monetarist non-Keynesian approach to monetary policy, based on a theory of a competitive supply of money. The key issue: the quantitative importance of this critique. Increases in aggregate supply tend to reduce prices (or inflation) and increase employment.

Prices are driven by scarcity or abundance of product or one of its components, without alternative.

Stephen Williamson points out that the Lucas critique was as much a problem for the money demand function as for the Phillips curve. 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. If the scarcity is of final product, its price will increase and it will become a local event, but if the scarcity is of raw material, so basic as energy producing raw material, it causes bottleneck in production and as result of it, in one hand it will cause scarcity and price increase in large range of products and on other hand unemployment.
