A cardinal review of Post-Keynesians of the New Consensus relates to their basic premises. Post-Keynesians think that merely pecuniary policy is non the best manner for polishing the economic system as it is suggested in NC, they believe in a policy mix, which involves: income policy, financial policy, pay bargaining.
The New Consensus believes that involvement rate accommodations can hold short-term effects on end product and long-term monetary value stableness, but has no existent effects, while Post-Keynesians believe that involvement rate accommodations have existent and long-term, and perchance lasting effects. They believe that money is endogenous and that it has existent short and long-term effects on unemployment, existent pay rate and growing. It has been criticized by Post-Keynesians that the rising prices aiming has led to policy recessions and it seems the policy is unable to cover with deflation because of lower edge on involvement rate.

In our paper we combined the critics of many Post-Keynesian economic experts, particularly we considered interesting: Philip Arestis, Malcolm Sawyer, Peter Kriesler and Marc Lavoie. First Lashkar-e-Taiba ‘s start from Philip Arestis.
In his paper ( 2009b ) Arestis summarizes Post-Keynesian people ‘s statements that are related with the part ( these statements raised after NCM model rating and with IT execution in different states ) . Let ‘s sum up the above mentioned statements:
Price stableness and low rising prices are n’t ever the factors of macroeconomic stableness ( Angeriz ; Arestis 2007/2008 ) ;
Insufficient grounds for a long-term perpendicular Phillips curve ( Juselius 2008 ) ;
Insufficient grounds that the NAIRU is unaffected by aggregative demand and economic policy ( Arestis ; Baddeley ; Sawyer 2007 ) ;
States that do non prosecute IT policies have done every bit good as the IT states in footings of the impact of IT on rising prices ( Angeriz ; Arestis 2007/2008 ) ;
Information technology policy model can merely feign to undertake demand-pull rising prices, but non cost-push rising prices ( Arestis/Sawyer 2009 ) .
In his another paper ( 2009a ) Philip Arestis besides mentioned the suggestions of ‘White ( 2006 ) ‘ , where he says that accomplishing monetary value stableness in the short-run may non be sufficient to avoid serious economic downswings in the average term. Examples are states which had monetary value and rising prices stableness, but could n’t last from deep crisis: Japan-the early 1990s ; the south-east-Asia: crisis-the late ninetiess, still deep crisis in summer 1997. Harmonizing to this, Post-Keynesians suggest that monetary value stableness should be pursued in tandem with other aims, particularly with end product stabilisation.
Post-Keynesians, following Keynes, reject the simple involvement rate ( investing relation ) described in the IS theoretical account. They believe, that the relation between involvement rates and investing is more complicated than it is assumed in the IS relation map. In add-on, many economic experts do non hold besides that there is a 1 for one relationship between the short term rate of involvement set by the cardinal bank, and the long term rate of involvement or the loaning rates which affect the aggregative demand ( P. Kriesler/M. Lavoie, 2007 ) .
3.2. Demand and Inflation
As we mentioned before, in the New Consensus Model pecuniary policy controls merely demand rising prices, but non cost rising prices, which is described in the signifier of involvement rates. The IT strongly believes that rising prices can be regulated by involvement rate policy with utilizing demand rising prices, and the executable equilibrium rate can equilibrate aggregative demand and aggregative supply and lead to a nothing end product spread. The Post-Keynesians raise a inquiry whether pecuniary policy is the most effectual manner of act uponing aggregative demand if it controls merely demand rising prices. Post-Keynesians critic is that pecuniary policy is ineffective at act uponing aggregative demand and rising prices ; they find that the impact of alterations harmonizing to the rate of involvement has a weak consequence on rising prices, while there are more significant effects on existent variables, particularly on investing, which thereby affects the future capital stock. There is besides the inquiry of whether the possibility of rewards, stuff costs and other none demand related rising prices could be as easy dismissed ( P. Arestis, 2009a ) .
Post-Keynesians are dubious about the impression that rising prices rises together with increased capacity use. Changes in capacity use demand to be inflationary at degrees of capacity near full use. Similarly, merely at really low degrees of capacity is possible some decrease of the rising prices rate. That ‘s why “ the Phillips curve would be horizontal for big scopes of end product and employment ( Freedman, Harcourt and Kriesler 2004 ” – P. Kriesler/M. Lavoie, 2007 ) . That ‘s why the mechanism of the upward inclining short-term Phillips curve transmitted to a perpendicular long tally Phillips curve will non keep in the instance of a horizontal Phillips curve, as increased end product will non, in the short tally, be inflationary. In this instance, the long-term Phillips curve will besides be horizontal over the relevant scope. In such instances, what is important is cost-inflation, as reflected in the lifting costs of trade goods, every bit good as the credibleness of the mark rising prices rate set by the pecuniary governments ( P. Kriesler/M. Lavoie, 2007 ) .
Advocates of Inflation aiming argue that end product stabilisation can be possible in the short-term, but it is non possible in the long-run, because end product will be returned to its degree of equilibrium. Supporters of rising prices aiming besides argue that pecuniary policy should be considered on end product and besides on monetary value fluctuations. The unfavorable judgment of Post-Keynesians is the followers: first of all they think that to follow rising prices aiming as a nominal ground tackle is non good, because it does non give adequate possibility to maneuver for the stabilisation of end product ( P. Arestis, M. Sawyer, 2005 ) .
The supply side of the economic system is really frequently introduced as unchanging supply side equilibrium, and the NAIRU is considered to sum up it. In NCM this equilibrium is represented as nothing end product spread. Post-Keynesians say that less utmost position would be if the supply-side equilibrium alteration during some periods but of class non harmonizing to the ‘demand side of the economic system ‘ by the alterations in labour market establishments and Torahs. The important inquiry of Post-Keynesians is if involvement rates have any durable impact on the ‘supply side economic system ‘ through their consequence on the degree of aggregative demand, ( in the context of IT ) . “ Even worse for the IT instance under the fortunes of a altering NAIRU, say due to productiveness additions, and to the extent that CB fails to account for it, rising prices would decline since the attach toing addition in RR* is non compensated by an tantamount addition in R ” ( P. Arestis ) . In the existent universe the CB does non straight observe RR* . Merely inferences about its degree can be gauged, said Post-Keynesians ( P. Arestis, 2009a:107 ) .
There is besides one factor which can be considered as a critical statement why Post-Keynesians are doubtful about the rising prices aiming being deficient tool in pecuniary policy. This factor is plus pricing. The instabilities and upsets in the balance sheet are more likely to happen in today ‘s environment of deregulated fiscal markets, basically due to their ability to introduce. Post-Keynesians consider that the instabilities created are non expected to hold immediate effects on rising prices, but can hold important employment and end product costs. These upsets: plus monetary value and debt bubbles, IT can non bring around. That ‘s why Post-Keynesians prefer extra policy steps. Furthermore, they think that rising prices aiming can make moral jeopardy in plus markets. Less attending is paid from the pecuniary governments during the period of upturn, but so they are obliged to protect the values of assets in the period of downswings. An statement in footings of plus monetary value control is that plus monetary value rising prices is non included in cardinal bank, because it is referred as one of the forces of market intercession and does n’t suit to the system of free market economic system. “ It is difficult to calculate plus monetary value motions accurately or to place plus monetary value ‘bubbles ‘ . Even if we could place them, it is non clear how efficaciously we could in pattern control them ” ( King, 2004b, p. 4 ” – P. Arestis and M. Sawyer, 2008, December ) .
In New Consensus a perpendicular long-term Phillips curve corresponds with possible end product which is consistent with the NAIRU and which does non hold a long-term tradeoff between rising prices and unemployment. Besides pecuniary policy ( involvement rate policy ) is impersonal in the long-run: it does non impact existent variables ( Employment, existent ingestion ) , but merely nominal 1s.
The rising prices rate additions when unemployment is below NAIRU, and decreases when unemployment is above it.
As pecuniary policy is thought to hold long-term effects, particularly from the side of investing, so the perpendicular Philips curve is wholly absent from this theoretical model. Post-Keynesians are critical about the perpendicular long-term Phillips curve. Some of them even think sceptically about short-term tradeoffs refering GDP/capacity and rising prices. There can be even two grounds for making this.
“ Large scope of capacity use rates which are consistent with an absence of demand-led force per unit areas ( Lavoie 2004, p. 24 ” – P. Kriesler/M. Lavoie, 2007 ) .
“ It is believed that with co-ordinate pay dickering an 8 changeless rising prices rate becomes compatible with a scope of employment degrees and the NAIRU as the short tally bound to employment is no longer alone ( E. Hein 2002, p. 314 ” – P. Kriesler/M. Lavoie, 2007 ) .
3.3. The Equilibrium Real Rate of Interest
The equilibrium existent rate of involvement is really of import facet in the NCM. “ The disagreement between the existent and the equilibrium rate of involvement has been termed the existent involvement rate spread and can be used to measure the stance of pecuniary policy. It is thereby a utile theoretical construct in the analysis of the relationship between the independency of pecuniary policy and economic fluctuations ( Weber, Lemke, and Worms 2008 ” – P. Arestis, 2009b ) .
In this paper is said that, when the existent rate of involvement is reached, there is no job of deficient aggregative demand and that the existent involvement rate is at an equilibrium degree of RR* . This equilibrium rate is frequently seen to match to the Wicksellian natural rate of involvement, the involvement rate impersonal to monetary values in the existent market, and at which supply and demand is at equilibrium. This natural rate of involvement equates salvaging and investing and does so at a nothing end product spread.
Flexible existent rewards would allow the labour market to clear with full-employment compatible with the nothing end product spread. As for Keynes, he one time accepted the impression of the Wicksellian natural rate of involvement, nevertheless he on the other manus rejected the thought of a alone natural rate of involvement, he argues that there is a natural rate of involvement to each degree of effectual demand which would convey salvaging and investing into balance.
Although the existent rate of involvement could play an of import function, there are some serious jobs still. For illustration, loan rates are of import when bank recognition is the chief beginning of financing the houses and families. Under such fortunes where the rate of involvement on bank loans differs from the policy rate of involvement, RR* may non be a utile index for pecuniary policy. Because of this rises a inquiry whether markets are frictionless or non. Indeed, in markets characterized by clash, a farther deduction is that pecuniary policy exerts existent effects even in the long tally. “ It might be hard for a cardinal bank that is unsure about the true theoretical account of the economic system to place its motions and to utilize it as regular index for the behavior of pecuniary policy ( Wicksell, 1898, p. 33 ” – P. Arestis, 2009b ) .
The chief issues that have been criticized by Post-Keynesians in NCM are the followers: first of all they say that NCM economic policy is non optimum, because they believe non merely pecuniary policy but other policies such as income policy, financial policy, and pay bargaining are besides of import. They believe that involvement rate accommodations have existent and long-term, and perchance lasting effects. They say money is endogenous and that it has existent short and long-term effects on unemployment, existent pay rate and growing. Post-Keynesians argue there is big border mistake in calculating rising prices which can damage the repute and credibleness of Central Bank. Some new Keynesian writers believe that short-term and long-term neutrality are accepted in pecuniary economic sciences. Post-Keynesians reject the neutrality of money both in the short-term and in the long-run.
In peculiar, they disagree with the underlying IS curve every bit good as the perpendicular long-term Phillips curve. They amended the perpendicular Philips curve, which basically change the theoretical accounts decision. The changed Philips curve outputs of import functions of financial and pecuniary policy in act uponing the degree of end product, capacity use and employment ( Lavoie, 2005 ) .
