The fact that large scale quantitative easing programs conducted by central banks has not caused inflation, provides a strong refutation of the mainstream Quantity Theory of Money, which claims that growth in the stock of money will be inflationary.
Answer: False
The answer is False.
The question requires you to: (a) understand the Quantity Theory of Money; and (b) understand the impact of quantitative easing in relation to Quantity Theory of Money.
The short reason the answer is false is that quantitative easing has not increased the aggregates that drive the alleged causality in the Quantity Theory of Money - that is, the various estimates of the "money supply".
The Quantity Theory of Money which in symbols is MV = PQ but means that the money stock times the turnover per period (V) is equal to the price level (P) times real output (Q). The mainstream assume that V is fixed (despite empirically it moving all over the place) and Q is always at full employment as a result of market adjustments.
Yes, in applying this theory they deny the existence of unemployment.
The more reasonable mainstream economists (who probably have kids who cannot get a job at present) admit that short-run deviations in the predictions of the Quantity Theory of Money can occur but in the long-run all the frictions causing unemployment will disappear and the theory will apply.
In general, the Monetarists (the most recent group to revive the Quantity Theory of Money) claim that with V and Q fixed, then changes in M cause changes in P - which is the basic Monetarist claim that expanding the money supply is inflationary.
They say that excess monetary growth creates a situation where too much money is chasing too few goods and the only adjustment that is possible is nominal (that is, inflation).
One of the contributions of Keynes was to show the Quantity Theory of Money could not be correct. He observed price level changes independent of monetary supply movements (and vice versa) which changed his own perception of the way the monetary system operated.
Further, with high rates of capacity and labour underutilisation at various times (including now) one can hardly seriously maintain the view that Q is fixed.
There is always scope for real adjustments (that is, increasing output) to match nominal growth in aggregate demand. So if increased credit became available and borrowers used the deposits that were created by the loans to purchase goods and services, it is likely that firms with excess capacity will re
The mainstream have related the current non-standard monetary policy efforts - the so-called quantitative easing - to the Quantity Theory of Money and predicted hyperinflation will arise.
So it is the modern belief in the Quantity Theory of Money is behind the hysteria about the level of bank reserves at present - it has to be inflationary they say because there is all this money lying around and it will flood the economy.
Textbook like that of Mankiw mislead their students into thinking that there is a direct relationship between the monetary base and the money supply.
They claim that the central bank "controls the money supply by buying and selling government bonds in open-market operations" and that the private banks then create multiples of the base via credit-creation.
Students are familiar with the pages of textbook space wasted on explaining the erroneous concept of the money multiplier where a banks are alleged to "loan out some of its reserves and create money".
As I have indicated several times the depiction of the fractional reserve-money multiplier process in textbooks like Mankiw exemplifies the mainstream misunderstanding of banking operations.
Please read my blog post - Money multiplier and other myths - for more discussion on this point.
The idea that the monetary base (the sum of bank reserves and currency) leads to a change in the money supply via some multiple is not a valid representation of the way the monetary system operates even though it appears in all mainstream macroeconomics textbooks and is relentlessly rammed down the throats of unsuspecting economic students.
The money multiplier myth leads students to think that as the central bank can control the monetary base then it can control the money supply.
Further, given that inflation is allegedly the result of the money supply growing too fast then the blame is sheeted home to the "government" (the central bank in this case).
The reality is that the central bank does not have the capacity to control the money supply.
We have regularly traversed this point. In the world we live in, bank loans create deposits and are made without reference to the reserve positions of the banks.
The bank then ensures its reserve positions are legally compliant as a separate process knowing that it can always get the reserves from the central bank.
The only way that the central bank can influence credit creation in this setting is via the price of the reserves it provides on demand to the commercial banks.
So when we talk about quantitative easing, we must first understand that it requires the short-term interest rate to be at zero or close to it.
Otherwise, the central bank would not be able to maintain control of a positive interest rate target because the excess reserves would invoke a competitive process in the interbank market which would effectively drive the interest rate down.
Quantitative easing then involves the central bank buying assets from the private sector - government bonds and high quality corporate debt.
So what the central bank is doing is swapping financial assets with the banks - they sell their financial assets and receive back in return extra reserves.
So the central bank is buying one type of financial asset (private holdings of bonds, company paper) and exchanging it for another (reserve balances at the central bank).
The net financial assets in the private sector are in fact unchanged although the portfolio composition of those assets is altered (maturity substitution) which changes yields and returns.
In terms of changing portfolio compositions, quantitative easing increases central bank demand for "long maturity" assets held in the private sector which reduces interest rates at the longer end of the yield curve.
These are traditionally thought of as the investment rates.
This might increase aggregate demand given the cost of investment funds is likely to drop. But on the other hand, the lower rates reduce the interest-income of savers who will reduce consumption (demand) accordingly.
How these opposing effects balance out is unclear but the evidence suggests there is not very much impact at all.
For the monetary aggregates (outside of base money) to increase, the banks would then have to increase their lending and create deposits.
This is at the heart of the mainstream belief is that quantitative easing will stimulate the economy sufficiently to put a brake on the downward spiral of lost production and the increasing unemployment.
The recent experience (and that of Japan in 2001) showed that quantitative easing does not succeed in doing this.
Should we be surprised. Definitely not.
The mainstream view is based on the erroneous belief that the banks need reserves before they can lend and that quantitative easing provides those reserves. That is a major misrepresentation of the way the banking system actually operates. But the mainstream position asserts (wrongly) that banks only lend if they have prior reserves.
The illusion is that a bank is an institution that accepts deposits to build up reserves and then on-lends them at a margin to make money.
The conceptualisation suggests that if it doesn't have adequate reserves then it cannot lend. So the presupposition is that by adding to bank reserves, quantitative easing will help lending.
But banks do not operate like this.
Bank lending is not "reserve constrained". Banks lend to any credit worthy customer they can find and then worry about their reserve positions afterwards.
If they are short of reserves (their reserve accounts have to be in positive balance each day and in some countries central banks require certain ratios to be maintained) then they borrow from each other in the interbank market or, ultimately, they will borrow from the central bank through the so-called discount window.
They are reluctant to use the latter facility because it carries a penalty (higher interest cost).
The point is that building bank reserves will not increase the bank's capacity to lend.
Loans create deposits which generate reserves.
Those that claim that quantitative easing will expose the economy to uncontrollable inflation are just harking back to the old and flawed Quantity Theory of Money.
This theory has no application in a modern monetary economy and proponents of it have to explain why economies with huge excess capacity to produce (idle capital and high proportions of unused labour) cannot expand production when the orders for goods and services increase.
Should quantitative easing actually stimulate spending then the depressed economies will likely respond by increasing output not prices.
The fact that is hasn't is not surprising if you understand how the monetary system operates but it has certainly bedazzled the (easily dazzled) mainstream economists.
