Implications Of The Policy Ineffectiveness Proposition Economics Essay

Implications Of The form _or_ system of administration Ineffectiveness Proposition Economics EssayThe Phillips Curve states that pompousness depends on expected rising prices, cyclical unemployment and supply shocks. It is given by the undermentioned equation The ostentation expectations can be either adjustive or rational. Early New Classical Economics was largely based the assumption of adjustive expectations, which assumes that people form their expectations of future lump based on recently observed inflation. This assumption implies that in absence of cyclical unemployment or supply shocks, inflation entrust continue indefinitely at its current rate. It also implies that past inflation influences the current allowance and prices that people set.If we suppose that the stock of money in the parsimony increases, the adjustment towards the long take on equilibrium takes time. In to individually one period that agents find their expectations of inflation to be wrong a c ertain similitude of their forecasting error would be incorporatedd into expectations. This means that the long run equilibrium in the economy would only be reached asymptotically. The government would then be able to maintain employment above its natural level.Rational ExpectationsHowever, m both economists disagree with the assumption of adaptive expectations. New Classical Theory replaced the assumption of adaptive expectations with that of rational expectations.Under this assumption, anticipated financial policy would have no effect on economic activity. However, stochastic shocks to the economy could have short run effects on economic activity. This theory known as the Policy Ineffectiveness Proposition was proposed in 1976 by Thomas J. Sargent and Neil Wallace. According to the prompting monetary authorities can non affect the output if the changes be anticipated. Under this proposition, the only way monetary authorities can affect the tangible economy is by make monetar y policy slight predictable. However, this would increase the variability of output around its natural rate and is hence not a desirable policy aim.Policy Ineffectiveness Proposition and the cave in RatioAn important implication of the Policy Ineffectiveness Proposition is that the monetary authorities can reduce inflation without any output or employment cost. If policymakers announce a drop-off in money growth, rational agents will lower their inflation expectations proportionately. This is known as the gratis(predicate) Disinflation Proposition. This in turn implies that the devote ratio, which is basically the loss in output for a reduction in inflation by one percentage point, should be equal to zero.Empirical EvidenceEstimates of the cost of disinflation vary widely. These estimates measured in terms of the sacrifice ratio have fundamental values. While some economists moot that a sound monetary policy can reduce inflation without any costs, separates estimate that som etimes the sacrifice ratio may have truly high values.Sargent (1982) examined the measures that brought extreme inflation under control in several European countries in the 1920s including Austria, Hungary, Germany, and Poland. According to him, in each case the inflation stopped abruptly rather than gradually. He studied these countries beca manipulation of the dramatic change in their fiscal policy regime, which in each instance was associated with the end of a hyperinflation. He also noted the rapid rise in the high-powered money supply in the months and courses by and by the rapid inflation had end.For Austria he suggested that currency stabilization was achieved very suddenly, and with a cost in increased unemployment and foregone output that was comparatively minor. From the data for Hungary, he inferred that immediately after the stabilization, unemployment was not any higher than it was one or two eld later. He posited that this could be because the stabilization proces s had little adverse effect on unemployment. For Poland, he noted that the stabilization of the price level in January 1924 was accompanied by an abrupt rise in the number of unemployed. Another rise occurred in July of 1924. He argued that while the figures indicated substantial unemployment in late 1924, unemployment was not an order of magnitude worse than before the stabilization. The Polish zloty depreciated internationally from late 1925 onward but stabilized in autumn of 1926 at around 72% of its level of January 1924. At the same time, the domestic price level stabilized at about 50% above its level of January 1924. The threatened renewal of inflation has been attributed to the governments premature relaxation of exchange controls and the tendency of the central cashbox to make private loans at scrimpy interest rates. The stabilization of the German mark was accompanied by increases in output and employment and decreases in unemployment. While 1924 was not a good year for German business, it was much better than 1923. From the figures, he couldnt find much convincing evidence of a favourable trade-off between inflation and output, since the year of striking inflation, 1923 was a very bad year for employment and physical production. According to the data, there was an evident absence of a trade-off between inflation and real output. However he suggested that the inflation and the associated reduction in real rates of return to high powered money and other government debt were accompanied by real over-investment in many kinds of capital goods.He concluded his findings by stating that the essential measures that ended hyperinflation in each of Germany, Austria, Hungary, and Poland were, premiere, the creation of an independent central bank that was legally committed to refuse the governments demand for additional unsecured credit and, second, a coinciding alteration in the fiscal policy regime. These measures had the effect of covering the governmen t to place its debt with private parties and foreign governments which would value that debt according to whether it was plump for by sufficiently large prospective taxes relative to public expenditures. In each case that he studied, once it became widely understood that the government would not avow on the central bank for its finances, the inflation terminated and the exchanges stabilized. He hike saw that it was not simply the increase quantity of central bank notes that caused the hyperinflation, since in each case the note circulation continued to grow rapidly after the exchange rate and price level had been stabilized.According his findings for the four countries, one may conclude that his studies supported the costless disinflation proposition. However there have been other studies that do not support this proposition.In his paper What determines the sacrifice ratio?, Laurence Ball investigatedConsiders several OECD countries.Finds that the cost of ending moderate inflatio ns can be high. Sacrifice ratio = cumulative output lost due to the permanent reduction in the inflation rate associated with the disinflationarypolicy.Average sacrifice ratio = 0.77% each p.p. reduction in inflation is associated with a 0.77 p.p. loss of output.Sacrifice ratio larger when disinflation slower, and in countries with greater nominal lease rigidity.Does not support costless disinflation propositionThe New Keynesian Stanley Fischer (1977) applied the insights of Franco Modigliani to the model employed by Sargent and Wallace. Fischer therefore introduced the assumption that workers sign nominal wage contracts that last for more than one period, wages argon sticky. The outcome is that government policy can be fully effective since although workers rationally expect the outcome of a change in policy, they are unable to respond to it as they are locked into expectations formed when they signed their wage contract. It is not only possible for government policy to be used effectively but its use is also desirable. The government is able respond to random shocks to the economy to which agents are unable to react, and so stabilise output and employment.Since it was possible to incorporate the rational expectations hypothesis into macroeconomic models whilst avoiding the stark conclusions that Sargent and Wallace reached, the policy ineffectiveness proposition has had less of a lasting impact on macroeconomic reality than first may have been expected.This applies much more generally. Any consistent set of government policies will be learned and anticipated by a population with Rational Expectations. Since they are anticipated, they will not come as a surprise. Instead, people will shift their short-run aggregate supply curves in such a way that production will be back at the NAIRGDP and unemployment at the NAIRU. If the policies are designed to move the economy away from the NAIRGDP, then they will be ineffective regardless what mix of fiscal and mon etary policies they are.This leads to the general Policy Ineffectiveness Proposition.Policy Ineffectiveness PropositionAny consistent government policies designed to influence the economy to a level of production other than the NAIRGDP will be ineffective if the population have rational expectationsThe essential measures that ended hyperinflation in each of Germany,Austria, Hungary, and Poland were, first, the creation of an independentcentral bank that was legally committed to refuse the governmentsdemand for additional unsecured credit and, second, a simultaneousalteration in the fiscal policy regime.37 These measures were interrelatedand coordinated. They had the effect of binding the government to placeits debt with private parties and foreign governments which would valuethat debt according to whether it was backed by sufficiently largeprospective taxes relative to public expenditures. In each case that wehave studied, once it became widely understood that the governmentwould n ot rely on the central bank for its finances, the inflation terminatedand the exchanges stabilized. We have further seen that it was notsimply the increasing quantity of central bank notes that caused thehyperinflation, since in each case the note circulation continued to growrapidly after the exchange rate and price level had been stabilized.Rather, it was the growth of fiat currency which was unbacked, or backedonly by government bills, which there never was a prospect to retirethrough taxation.The changes that ended the hyperinflations were not isolated restrictiveactions within a given set of rules of the gritty or general policy.Earlier attempts to stabilize the exchanges in Hungary under Hegedus,38and also in Germany, failed precisely because they did not change therules of the game under which fiscal policy had to be conducted.39In discussing this subject with various people, I have encountered theview that the events described here are so extreme and bizarre that theydo not bear on the subject of inflation in the contemporary United States.On the contrary, it is precisely because the events were so extreme thatthey are relevant. The four incidents we have studied are akin to laboratoryexperiments in which the elemental forces that cause and can be usedto stop inflation are easiest to spot. I believe that these incidents are full oflessons about our own, less drastic predicament with inflation, if only weinterpret them correctly.Costless immediate disinflation is not possible in an economy with long-term labor contracts. This paper sets out a simple contracting model of wage andoutput determination and uses it to calculate sacrifice ratios for a disinflationprogram, under the assumption that announced policy changes are immediatelybelieved. Under this assumption disinflation with a structure of labor contractslike those of the United States would be less costly than typically estimated.The model is then modified to allow for the slow adjustment of expe ctations ofpolicy to actual policy sacrifice ratios then approach the ranges typicallyestimated.The sacrifice ratio for the current disinflation is mensural in the lastsection the current disinflation was somewhat more rapid and less costly thanprevious estimates suggested. The calculated sacrifice ratio is consistent withthe predictions of the simple contracting model.Inflationary expectations and aggregate demand pressure are twoimportant variables that influence inflation. It is recognized that reducinginflation through contractionary demand policies can involve significantreductions in output and employment relative to potential output. Theempirical macroeconomics literature is replete with estimates of the socalledsacrifice ratio, the percentage cumulative loss of output due to a 1percent reduction in inflation.It is well known that inflationary expectations play a significant role inany disinflation program. If inflationary expectations are adaptive(backward-looking), wage c ontracts would be set accordingly. If inflationdrops unexpectedly, real wages rise increasing employment costs foremployers. Employers would then cut back employment and productiondisrupting economic activity. If expectations are formed rationally (forward2looking), any momentum in inflation must be due to the underlyingmacroeconomic policies. Sargent (1982) contends that the seeming inflationoutputtrade-off disappears when one adopts the rational expectationsframework. The staggered wage-setting literature provides evidence thateven if expectations are formed rationally, wage and price determination willhave backward-looking and forward looking elements. The backwardlookingelement reflects last years contracts on this years prices whereas theforward-looking element reflects next years contracts on this years prices.Taylor (1998) presents a detailed account of the staggered wage and pricesetting literature, and the exercise will not be pursued here. Calvo (1983)shows that in a world of stochastic contract length, the costless disinflationresult extends to a world of staggered wage contracts with forward-lookingexpectations. filet inflation is then a matter of a resolute commitment onpart of the government to a credible disinflation program.In this literature, the costless disinflation result extends to a world ofstaggered wage contracts with forward-looking expectations. Stoppinginflation is then a matter of a resolute commitment on the part of thegovernment to a credible disinflation program.It is likely that in an economy there are both forward- and backwardlookingelements in inflationary expectations. Chadha, Masson, andMeredith (1992) (henceforth CMM), provide a unified framework to test forexpectations formation in a single specification. CMM use a Phillips curveframework to consider two benchmark cases a Phelps-Friedman adaptiveexpectations model which places a weight of unity on past inflation(complete inflation stickiness) and a rational staggered con tracts modelbased on Calvo (1983) that places a weight of unity on expected inflation(inflation is independent of past inflation). These two extremes are nested inone specification where current inflation is a weighted average of past andexpected future inflation.
