We internalise and reproduce its creeds. Thanks. It doesn’t look like the latest study will change minds either. Shame Mukoka, Critique of Phillips Curve: A Case Study of Zimbabwe Economy, Economics.Vol. The Phillips Curve – Uk Case 2 Vol. Stable inflation expectations. Price inflation is affected by many factors, and the “long term” can be many decades in duration. 2265: ... We show that the orthodox view that the New Keynesian Phillips curve is vertical in the long-run and that it cannot generate substantial inflation persistence relies on the implausible assumption of a zero interest rate. People believe that is unsustainable, and that the economy will revert to the natural rate of unemployment, the vertical line. All these and more suggest that the total amount of capital is increasing. And how exactly do you do that (reform education) given how instrumental it is for neoliberalism to continue. Telling the rich and powerful what they want to hear is both possible and profitable. That real sciences have laws that are universally applicable or can at least be reconciled across levels of reality with the consistency you’d expect of something labelled a science (e.g. There are also cultural changes, so that people distrusted the government and did not demand heavy regulation and enforcement and somehow came to believe they were entrepreneurs of the self. Turn it around. Nobody really knows for sure, but at least there was a major measurable change that took place in 1970: peak oil in the US. Bill Mitchell has a blog post on this very subject. These were a modest but viciously fought concession in order to avoid the kind of extra-constitutional change experienced by Russia a few years later. The Phillips Curve was the justification for those rate hikes. Over the same period, literature met Oliver Twist and Alice and her rabbit hole, was jostled by Hardy and Lawrence, and jolted by Joyce, Woolf and Eliot, not least because a woman writer demanded a room of her own. When that happened the link between … There’s a persuasive interpretation of Phillips’ original work and application to US data by John Hussman, which argues: 1) Phillips’ original paper is right but most of the work since is garbage which missed the point. So, what was that “something” that changed everything in the early 1970s? It shows how Keynesianism died the last time and its defenestration marked one of the most stunning achievements of Milton Friedman who was born a century ago this year. The Phillips Curve Definition. Demand shocks are much bigger than supply shocks 3. The combined losses were more than made up by increases in the profits share. It is incorporated in most econometric models, modified by some other variables and terms, including levels of taxation, expectations of inflation, inflation inertia, which relates to price and wage rigidity in the short run, and a host of other terms. The Leubsdorf article has several quotes from Very Serious People to the effect we think there’s a relationship and we’re going to act like there is a relationship, and we can fine-tune the economy with our gut instincts. When workers receive less and less of what they produce, they lack the purchasing power to push up prices. Their PC was vertical in the long run at the natural unemployment rate, and their short-run curve shifted up whenever unemployment was … Paul Samuelson and Robert Solow picked up on the Phillips paper with a paper of their own in 1960. Thanks for the links. Keynesian economics advocated increasing a budget deficit in a recession. Looks like you’ve clipped this slide to already. IV, Issue 4 August 2014 inflation dynamics”. But the problem is that there is also no apparent connection in the short run either. of earlier Phillips curves about ad hoc treatment of expectations or to the Lucas critique of econometric accelerationist Phillips curves. Most economists now accept a central tenet of both Friedmans and Phelpss analyses: there is some rate of unemployment that, if maintained, would be compatible with a stable rate of inflation. 2) Phillips’ correct result is a relationship between unemployment and real wage growth (“wage inflation”), not consumer prices. There is FRED Graph data on this going back to 1950, which is graphed monthly in the National Economic Trends report by the St. Louis Federal Reserve. 5 Consider a company like Google. When people do discuss profits, it’s always in the context of the importance of capital and the need to coddle it. Data used in this analysis was on quarterly basis from 1994 to 2010. What better way to make something appear scientific than to riddle its academic literature with curves and formulas, and give it its own pride of place at the nobles side by side with real sciences. Never mind that your children no longer have a school playing field: if they get fat, it’s your fault. Now customize the name of a clipboard to store your clips. It has been a staple part of macroeconomic theory for many years. {facepalm}, If neoliberals were intellectually honest, they wouldn’t call it supply side economics, they’d call it philo-capital economics. Too little variability in the data.Since the late 1980s there have been very few observations in the macro time-series data for which the unemployment rate is more than 1 percentage … They rebranded to try to get around all the artificial selection in the global economy. The problem isn’t that they’re using math — it’s that they’re not using math, they’re using mathematical formulations to bamboozle people. The Phillips Curve showed that there was a trade-off between the inflation rate and the unemployment rate.Alban Phillips based the original work on data from the UK from 1861-1957. [2] Sie ist seitdem mehrfach modifiziert worden, etwa von Paul A. The graph on “disconnect between productivity and worker compensation”, above…the divergence around ’76…the value represented by the gap; is for well-deserved executive compensation? So, inflation is equal to a power of unemployment (magic number?) Therefore, I’d rewrite Equation 3 this way: 5. The lack of connection to theory is especially obvious in the current expansion. The Crystal Palace’s startling iron pillars and acres of glass yielded to curtain walls and structural steel. They are right that the model is flawed, but they are criticizing it for the wrong reason. Over time, the effect of these changes caused the gap. That’s not true. Money produced in the economy goes either to capital or labor. Learn more about the Phillips Curve here: ... A Critique of the Phillips Curve Alex Merced. The real math would be really, really hard, but the economist are taking phrases like “inflation is wage growth that is higher than productivity growth”, then mystify it by turning it into an algebra 1 equation. Ben Leubsdorf wrote a very readable criticism for the Wall Street Journal on August 14, 2014, just before the Fed started raising interest rates. Gordon says much of their paper is a discussion of pre-Phillips theory. M. Friedman and E.S. During that period the labor share declined 10% from a larger starting point. I have been dealing with a couple of engineering problems today where the publication I am using has over 50 design charts just for gravity pipe flow. Among the many factors that might confound that model, one factor of interest is the fraction of national output received by workers as wages vs. the fraction retained by corporations. https://www.nakedcapitalism.com/2016/05/naked-capitalisms-diptherio-discusses-flaws-in-unemployment-reporting.html. That view lies at the heart of neoliberalism, and at the heart of Fed policy.”. Anchored expectations.The Fed’s success in limiting inflation to 2% in recent decades has helped to anchor inflation expectations, weakening the sensitivity of inflation to labour market conditions. I see an analogy here, maybe I am wrong. When people do discuss profits, it’s always in the context of the importance of capital and the need to coddle it. Scientific evidence hardens claims into hard facts, and does so quickly. Speaking for myself, the wage-productivity gap is directly the result of the imposition of neoliberal ideas about deregulation, crushing unions, outsourcing, and a host of other similar structural changes. So what to do — do you try to change the way economics is practiced? He of course, will memorize all manner of arcane sports trivia and statistics, but when it comes time to quantify his own economic doom, or to think about his or her own economic travails with numbers and curves, it’s mind shutdown time. That story puts a new spin on “publish or perish”, something like “(you) publish and (a lot of other people will) perish (sooner)”. In an early draft of this article, I had a reference to Econned, where Yves discusses the use of the Gaussian Copula in the organization of RMBSs. The Phillips curve is a single-equation economic model, named after William Phillips, describing an inverse relationship between rates of unemployment and corresponding rates of rises in wages that result within an economy. Low unemployment is correlated with a rise in inflation. Ditto for other countries, so far as I know. The phrase already tells you they’re just throwing out a feeling they have — why should inflation be directly coupled to “excess wage growth”? For example, the recursive estimate of the unemployment coefficient in the core PCE Phillips Curve has fallen a little from -0.09 to -0.07 since the Great Recession. It’s simpler than Navier-Stokes? If we set inflation at zero, Equation 1 says that wage growth equals productivity growth. Phillips Curve has ever been ideological nonsense. He says that Samuelson and Solow were not talking about the situation that came about in the 70s, but rather the situation in the early 1960s. However, it is argued this causes crowding out. Phillips Curves and Unemployment Dynamics: A Critique and a Holistic Perspective August 2006. In this September 26 New York Times article there are more Very Serious People explaining they need to follow their instincts about the economy in deciding on interest rates and they are sure inflation is coming. The True Phillips graphs in these two articles are much more compelling than the ones posted here on N.C. And from January 19, 2010 (emphasis added): “When labor is scarce (low unemployment), the price of labor tends to rise relative to the price of other things (thus we observe real wage inflation). Over the past thirty years, I can think of four major changes off the top of my head that lead me to expect the Philips curve to translate in multi-variable space: 1. I buy Ugo Bardi’s analysis over at Cassandra’s Legacy: An asteroid called “Peak Oil” – the real cause of the growing social inequality in the US. The Phillips Curve was criticised by monetarist economists who argued there was no trade-off between unemployment and inflation in the long run. The labor share is declining he says. This equation calls attention to the role that profits play in the economy, something economists generally generally ignore. The short term component. The Phillips curve helps explain how inflation and economic activity are related. Technology, as today, raced headlong. Thanks for this very readable and important post. Corn prices soared as well as wheat, soybean prices, due to the need to replace the food content of corn plus the myriad other uses of corn. Stated simply, decreased unemployment, (i.e., increased levels of employment) in an economy will correlate with higher rates of wage rises. Some of the gains might be used to cut prices, I suppose, but surely most of the gain stays with the company. This is one reason why America is being parasitized by finance —- Math. Stage coaches gave way to steam railroads; the telegraph to the telephone and wireless; lances, swords and muzzle loaders to dreadnoughts, flying machines, automatic weapons and poison gas – all with vastly different supply chains, need for capital and levels of employment. The idea seems to be that using the right set of assumptions, we can make sense of the fact that the planets that circle around the Earth keep stopping and going backwards. Cancel Unsubscribe. And mot just economically, but socially as well. 2019), we argue that there are three reasons why the evidence for a dead Phillips curve is weak. Keynesianism lost out and was replaced by monetarism. Suppose the beginning rates of inflation and unemployment are at Point A on the above chart. It shows very high inflation at very low unemployment, but falls quickly as unemployment rises. They can’t find data on the US economy similar to that found by Phillips for the UK economy, so they work up some of their own data and make some calculations showing a result similar to that of Phillips. vlade hit on a key point, IMO. Add living in an age of credentialism to the mix and the general ineptitude of our ruling politicians and one can see how economists can wreak so much havoc with their ex-cathedra pronouncements on what makes the economy work…. Demystify the Phillips Curve and other economic “truths” being used against Main Street is significant. Picture bull-fighting, an appropriate concept,I think. (It took a few years for agronomists to develop seed corn that was immune to that leaf blight). Preisniveauänderungen auf der einen und der Arbeitslosenquote auf der anderen Seite beschreibt. They’ve been strangling the latter department since while ensuring steady flow of grants to the math-based department, a la the Phillips story alluded to above. Clipping is a handy way to collect important slides you want to go back to later. Criticism of the Phillips Curve. That year, due to a southern hurricane, southern leaf blight was blown into the Midwest resulting with the devastation of that year’s corn crop throughout the Midwest corn growing area. https://www.theguardian.com/business/2017/oct/26/worlds-witnessing-a-new-gilded-age-as-billionaires-wealth-swells-to-6tn. Making this work with Barkai’s analysis is harder. Just like court magicians or priests divining augers for their emperors. In this specification, core inflation depends on short-term unemployment and on expected inflation as measured by long-run forecasts from the Survey of Professional Forecasters. The samples sampled are slices of time which will never return, yet the curves tell us that they will only return. Attempts to limit competition are treated as inimical to liberty. augmented Phillips curve, which links in⁄ation to expected in⁄ation and some measure of economic activity, has become a key element in monetary economic models. Their Phillips curve was vertical in the long run at the natural unemployment rate, and their short-run curve shifted up whenever unemployment was pushed below the natural rate. It hasn’t looked like x = y – z for most interesting problems for 200 years — pre-Newton even. The inflationary periods in US history that I’m familiar with seem to have all been caused by supply shocks (i.e. The Phillips Curve is now free from the bonds of factual data that gave Phillips his interesting result. A recent paper by Simcha Barkai, Declining Labor and Capital Shaes, provides a convincing explanation. The Philips Curve exemplifies the dysfunction created by separating mathematical/quantitative descriptions of an economy from that same lived economy and its history. 2014 / 08 / 25. We’re still far from the point that the Fed realizes, as Copernicus did, that the prevailing dogma is not descriptive of the world. Conversely, and as seen in this data for the 1970s, when workers’ share of the economy is above its historical average and rising, price inflation can be exacerbated. The triumph of the Phillips Curve in post war economics was not quite so complete but its rise, fall, and fallout, is a fascinating intellectual episode. A suffrage limited to propertied men became universal. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. So I believe the Philips curve is valid but it is in a different place in multi-variable space each decade or so based on fundamental changes in the economy. Why would we expect to have a nice linear relationship between unemployment and wages across this period? "But Friedman said the Phillips curve couldn't be sustained. So I think we see the Philips curve predictably happening in the short-term in fields like technology where there is big demand and not enough people. 8-13.

Trouble is the Proof is Patchy (sadly behind a paywall; it’s available online at your local library). If the amount of capital deployed had increased as might be expected with this large drop in cost, the capital share might have remained the same. Nonetheless, two criticisms of the expectations-augmented Phillips curve deserve notice. He shows that the cost of capital has declined by 7% over the period of his study, 1984-2014. That one comes from the Philadelphia Fed in August 2017, Do Phillips Curves Conditionally Help to Forecast Inflation? That suggested to Samuelson and Solow that there is a trade-off if the economy is in specific parts of the Phillips Curve: by allowing a slightly higher level of inflation, you could get a big drop in unemployment. People weren’t worried about these gigantic businesses before the Great Crash, and the Obama Administration did nothing about anti-trust until the end of his term. You can change your ad preferences anytime. Free trade agreements (NAFTA etc.) Here p is inflation, w is wage growth, and k is productivity growth. I also suspect most modern recessions have not been caused by the low unemployment, but rather by the credit tightening applied to prevent low unemployment – to prevent workers from enjoying higher wages at the owners’ expense. We have already seen that the first notable failure of the Phillips Curve was used to undermine Keynesian economics in favor of monetarism. (Especially in an economy with high corporate profit levels and inadequate price competition.). Profits add to the value of the firm, and are distributed by the owners of firms as they see fit, which isn’t to lowly workers. Not to ruin a good theory with the facts, the failure of this misguided Phillips Curve formulation to describe the real world has resulted in a wide variety of ways to “augment” it using expectations, varying “natural” rates of unemployment, and so forth. I wonder what would happen with my Equation 1b, derived from Simcha Barchai’s work. If I’m not mistaken, in the 70’s NAIRU was considered to be 6 or 7 %. Also, the billionaires of the world now control $6 Trillion. For most people, being confronted with “scientific evidence” is enough to lay to rest any and all doubt about the claims being made in a proposition. That the Fed has an equal responsibility to promote employment seems to have been pixie dusted away. See our Privacy Policy and User Agreement for details. See our User Agreement and Privacy Policy. There is some evidence wages are firming up today, and maybe even rising a fraction faster than inflation. Never let the facts get in the way of a convenient, wrong argument that supports what policy makers and their patrons want done. In the late 1960s the stable negatively sloped Phillips Curve (PC) was overturned by the Friedman-Phelps natural rate model. Never mind structural unemployment: if you don’t have a job it’s because you are unenterprising. minus productivity plus a constant (magic number again?). It was also generally believed that economies facedeither inflation or unemployment, but not together - and whichever existed would dictate which macro-e… The Phillips Curve has been controversial for a long time, as Mankiw admits in his introductory textbook. De facto imperial relations existed with much of Latin America, the Caribbean and East Asia. It’s listed in the popular introductory economics textbook by N. Gregory Mankiw as one of the Ten Things All Economists agree on. The organisation of labour and collective bargaining by trade unions are portrayed as market distortions that impede the formation of a natural hierarchy of winners and losers. ), Hussman followed up the original piece with some others in recent years: The natural rate of unemployment and the z term vary over time, and for some reason so does the e term. 1 INTRODUCTION The empirical studies on the Phillips curve analyzing the relationship of un- I see neoliberalism as the Matador, education as the cape, and the public as the bull. By what logic would the statistics of economic relations, of changing notions of acceptable levels of employment and inflation (capital’s nemesis), not be affected by dramatic changes in social, political and economic conditions? That dwarfs the make-believe $4K-9K per household the Republicans promise from their proposed tax cuts. He fitted a curve to the data, and then compared that curve to UK data from two later periods. Phillips curve analysis has hardly stood still since its beginnings in 1958. In this post, I discuss the derivation of the Phillips Curve, its adaption by Samuleson and Solow to manage the economy, its breakdown in the 1970s, exploitation by neoliberals of that breakdown to replace Keynesian demand-based economics with monetarism and supply-side economics, its rejuvenation, and the evidence that it doesn’t make accurate predictions. As a result, the Phillips Curve shifts up and to the right over time, so that the economy moves to Point C, with the beginning unemployment rate but higher inflation. The average American’s eyes glaze over as soon as you put up a math formula. But over the past decade, in⁄ation in the U.S. appears to have deviated from the behavior predicted by the Phillips curve. A matter of rhetorical Supply & Demand, come to think of it. And which is the cause and which is the effect? Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Gordon himself proposed a version of the Phillips Curve designed to deal with the problem of supply and demand shocks like the Oil Shock: In Equation 3, the second U term is the natural rate of unemployment, zt represents cost-push pressure, and et is apparently a constant. ” This equation calls attention to the role that profits play in the economy, something economists generally generally ignore. The Fed lowers interest rates resulting in a small increase of inflation, so that the economy moves to Point B with lower unemployment. Phillips curve fits the entire period from 1985 to the present. So the questions above might be rephrased as … from the bull’s perspective, do you chase the cape or gore the matador? His title is The Fed Has a Theory. Leubsdorf confirms that most economists believe that there is a short run trade-off between inflation and unemployment and also agree that this trade-off doesn’t hold in the long term, meaning that we can’t get permanently lower unemployment by accepting a bit more inflation. The Phillips Curve traces the relationship between pay growth on the one hand and the balance of labour market supply and demand, represented by unemployment, on the other. The ability to control markets gives firms the ability to cause price shocks, as when pharmaceutical companies drive up the price of epi-pens or other drugs, but also the ability to gradually increase prices above the rate of inflation. P. 3. However, as a general rule across the economy, I simply don’t see why the relationship between inflation and unemployment should be the same today as it was in 2007, 1997, 1987, or 1977. Whereas Phillips does not mention the possibility that the curve might shift, Samuelson and Solow find such shifts and offer possible explanations, such as strong labor unions. Ben Leubsdorf wrote a very readable criticism for the Wall Street Journal on August 14, 2014, just before the Fed started raising interest rates. Section 3 presents empirical evidence on the aggregate relationship between unemployment and inflation. Meanwhile, the economy continues to add jobs with no obvious increase in inflation as shown by the blue line on the above chart. …not just “math”: Rand-Friedman-libertarian ideological definition: “Neoliberalism sees competition as the defining characteristic of human relations. It almost like, when it suits the capitalists, they stop believing in this whole “invisible hand” thing….strange…, *blushes* Applying simple logic to mainsteam economics is always entertaining…when it’s not maddening…. The changes in social, economic and political life were comparable. I was managing farms in Iowa in 1970. The rich persuade themselves that they acquired their wealth through merit, ignoring the advantages – such as education, inheritance and class – that may have helped to secure it. I was told he just wanted to get something out, and this was the first idea he had so he wrote it up, but wasn’t really persuaded.. Here’s a schematic drawing of the Phillips Curve from Wikipedia: The standard curve might be the one on the left. Good article. But for all the alleged “progress,” it seems we’re trapped in a culture that really finds it hard to let go of the 19th Century. When OPEC massively increased the price of oil in the early 70s, inflation soared far past the level suggested by the Phillips Curve. As a result, working people of all classes were doubly harmed, first by the abandonment of the Fed of any significant role in cutting unemployment, and second by the savage use of high rates to control inflation. Phillips Curve: The Phillips curve is an economic concept developed by A. W. Phillips showing that inflation and unemployment have a stable and … They give PhDs for this stuff? At some point, business leaders would wise up, figure out that the reason the prices they can charge are getting higher is because of inflation, not an increase in real demand. So, yes, it’s largely the math that Samuelson and Solow and the people who came later loved. In contrast, when labor is plentiful (high unemployment), the price of labor tends to stagnate relative to the price of other things (real wages stagnate).”. Learn more. That paper strikes a serious blow at the heart of neoliberal antitrust law, but it also explains the wage-productivity gap and shows the way to social changes that would benefit most of us. Issue with the copula were nonesense assumptions. The damage to the real world the academia demands does.. “Real world” powers can riffle through the files of academia, hard and soft sciences or the various humanities or whatever, even languages and linguistics, and, because “freedom,” can always come up with something published that “proves” whatever line of BS the looters are pushing at any given moment to increase their “take.”, But then ever since humans discovered ratiocination, thus it has always been. I recommend Mitchell and Muysken’s “Full Employment Abandoned.” They harpoon the Phillips Curve, the ‘natural’ rates of unemployment and interest, NAIRU and more. an aside: For readers who do not ‘read math’ you provide understandable English translations of the equations. 1. The Phillips Curve says that there is an inverse relation between unemployment and inflation. What if you have high productivity growth for a few years without wage growth, and then you have wage growth without high productivity growth? Not much “neo” about it. how quantum electrodynamics reconciles classical electrodynamics at the atomic and subatomic levels) seems to be a minor inconvenience to those with vested interests in having economics accepted by the public as a hard science (precisely, I say again, because presenting “scientific evidence” with formulas and curves disarms most people, among them the political ruling class, of their critical thinking faculties). The required return on capital is approximately and sensibly defined as the cost of obtaining capital in the financial markets. All that increase is funded by the gains from productivity. The wage line is for production and non-supervisory personnel, which the EPI says is about 80% of employed people. First, economists of the new classical school argue that people form expectations rationally. Scribd will begin operating the SlideShare business on December 1, 2020 It is a model that works under extremely limited conditions: 1. I also suspect the true reason why central banks fear low unemployment is because those increases in workers’ wages will come at the expense of corporate profitability. I conclude with some observations based on an important paper by Simcha Barkai that challenges the core beliefs of neoliberalism. There was a remarkable similarity for most of the two periods, with exceptions Phillips explains away. Additional inflation brought almost no further drop in unemployment Milton Friedman, Edmund Phelps, and others suggested a reason: As people become used to higher inflation, the Phillips curve shifts upward A graph of the historical values of the terms in Equation 1a could be very enlightening. In a recent paper (Hooper et al. The curve … the Phillips curve. I am sorry that I do not have it to hand. Baby boomer demographic moving from entering peak productivity to retirement age Or consider a company that outsources its labor. Inflation is currently running at 1.3%. The stakes are high for the matador — although as a spectator that fact is hidden in plain sight. We can substitute Equation 1a into Equation 1 to get the original Phillips Curve. the main feature of empirical Phillips curve models, that is, that inflation rises when labor markets tighten, appears to be turned on its head during the economic expansion of the 1990s, when the unemployment rate fell below its long-run average of around 6 percent and then slid under 5 percent, while inflation fell. Was there some other massive policy shift that could so decisively alter the prior reasonable trend? Inequality is recast as virtuous: a reward for utility and a generator of wealth, which trickles down to enrich everyone. (A hard-fought concession to a new, competing power block of manufacturers, their financiers and traders,) A major constitutional crisis in 1910-11 presaged adoption of Bismarckian welfare programs, which America did not see until FDR and LBJ. The poor begin to blame themselves for their failures, even when they can do little to change their circumstances. You’ll note that I only use very simple math, mostly because it’s a nice shorthand, like Equations 1a and 1b. This is where capital growth fits in. It can buy a few more computer blades and serve more customers with little or no increase in total wages. De jure imperial relations existed with India and the “white commonwealth” countries of Canada, Australia, New Zealand and South Africa (post-Boer War). 2. Seconding diptherio – I remember the introductory statistics and econometric courses I was required to take, where we’d routinely dissect econ reporting in the press based on flawed mathematics or poor statistical methods, and yet carry as though these were meaningful and useful figures (e.g. Loading... Unsubscribe from Alex Merced? Might I suggest “capitalphilic economics”? They try to predict the future of a chaotic system, which is impossible. So naturally Republicans want tax cuts for the pig rich. The consensus was that policy makers should stimulate aggregate demand (AD) when faced with recession and unemployment, and constrain it when experiencinginflation. Early Criticism of the Phillips Curve Early critics noticed that after a few years,the Phillips curve no longer worked well asa policy menu. They also had a formula to replace the Phillips Curve as a predictor of inflation. This part is based on Sections I-III of Robert Gordon’s article, The History of the Phillips Curve: Consensus and Bifurcation, Economica (2011) 78, 10–50 (behind paywall, but you can find it online at your local library). Tax and regulation should be minimised, public services should be privatised. Technology displacing workers Barkai shows that concentration of industries is the direct result of changes in the anti-trust system, and that the gap is larger in more concentrated industries. But as we shall see, it doesn’t work as a predictor. It you need to explain economics in a nutshell to a working guy who thinks nothing is really all that complicated (were it not for intellectuals over-thinking things), it fills the bill rather nicely. That view lies at the heart of neoliberalism, and at the heart of Fed policy. Following tradition but not evidence, the Fed is raising rates. Is it leaving the gold standard? The following chart shows the sudden growth in top wealth. The evidence for the U.S. suggests that the slopes of the price and wage Phillips Curves– the short-run inflation-unemployment trade-offs – are low and have got a little flatter. Parliament expressed that power shift, for example, by ending tariffs protecting domestic grain production, substituting, instead, subsidies for imported food stuffs, in order more cheaply to keep workers fed and at their machines. Most middle-school algebra doesn’t have cause and effect – just a first order connection. J. Beggs/ThoughtCo. 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. However, some feel that the Phillips Curve has still some relevance and policymakers still need to consider the potential trade-off between unemployment and inflation.
