I think this is really interesting in terms of how M, V, P and Y are defined. So correct me if I'm wrong but here's how I'm thinking about it. If the amount of money (M) increases, the value of the dollar decreases so prices must go up. If the velocity of money (V) increases, that means more people are buying, thus increasing demand and according to supply and demand theory, the demand line moves to the right thus increasing the price. If the number of products (Y) decreases, the value actually goes up because it becomes rarer (and assuming that people want it), the price will increase. (Think luxury cars and really rare trading cards)

Agreed. I would have liked it if, as with GDP, they had plotted the money velocity over time as well, just to see if it really is as flat as is implied.

Hello, if we are evaluating "large and sustained changes in price levels" (i.e. we are looking at the long run?), shouldn't it mean that we can consider Y and v as variable ? Since you are also acknowledging that real GDP and velocity of money don't change in the short run, but they do in the long run?

Thank you sir

What exactly do you mean by Money Supply?

As Argentinian, can confirm

You misquoted Friedman. He actually said: “Inflation is always and everywhere a monetary *phenomenon*" (not "phenomena", which is the plural form, and obviously unsuitable in that context).

what a great video, but why there is no inflation after printing so much money by the Central bank?

Thank you for your videos, they are very educative. However I must point out something, in 5:21 the line drawn on the graph is not correct. That's not a good fitting of the observed data. If you would fit a line, the line that best fits would somewhat have half of the data points above it and half below it. That would remain a linear fit, but not "perfectly linear" that would indicate that the primary cause of inflation is money supply but doesn't account perfectly for all the inflation.

Great video. However, not sure you can always assume Y is long term stable. What about exponential growth driven by tech, like in consumer electronics? This actually causes deflation in terms of bang for the buck. And this is a long term trend. Really extraordinary in the face of government programmed growth in the money supply and expanding credit.

@MarginalRevolutionUniversity

The idea is that Y doesn't fluctuate dramatically in the short term. Over longer periods a steady growth rate can mean big changes in Y, and yes, if M doesn't keep up, you can see deflation. Larry White brings this up a bit when he discusses the 19th century gold standard in this Econ Duel: kzread.info/dash/bejne/eJZ4vJKIkrW-lqg.html&list=PL-uRhZ_p-BM5B-q4URjHtVKY0hekfExEx&index=6 -Roman

what if there are more than three causes that can be identified? What about outside influences such as tsunami in bread baskets of world or every oil cargo sank

Japan has deflation for years and money supply growth beyond limits. This theory has an issue. Also saying that the velocity is more or less stable is at least something to debate about. In US M2 is goes up, I see no signs of inflation. The velocity drops to record low levels because it does not go to main street but to wallstreet. Same here in the EU.

is velocity of money related to the marginal propensity to consume?

What should be said too is about money allocation. When money are allocated to financial market and real state the price of stocks, houses and bonds skyrocket and bubble are caused but they do not make part of official inflation index. How convenient for use of QE money, for exemple. And how convenient for speculation and distortion of values of society. Price affects V and M affects Y. Therefore manipulating P and M manipulates V and Y. The manipulation of P and M are easily done in open society. As in free market theory, the two factors dictates the direction of price as in stock and commodities exchange i.e. , greed and fear. Causing greed and fear in the economic society obtain change in Velocity by causing significant change in price. In panic of deflation, V slows down much quickly and deeply than the impact when comes the greed of inflation and V speeds up. Therefore, by using manipulation on M can obtain manipulation of V and both mutually manipulate P and vice versa.

great one. But velocity of money is an important fact lately. Japan, USA and EU are increasing the M but P is not growing because commercial banks are not "sharing" the money, so the V became a matter of fact. am I wrong?

Great! :) I don't know USA that much. Gonna explain my idea: In EU (specially Italy, my country), the problem seems to be that yes, M is growing, but not in real economy. Commercial banks are keeping the QE M money as reserves (although negative interest rates) and not loan families, companies etc. So, M growth is just "theory". In real world we don't have it because V is very very low. I could say that in Italy we had zombie banks that have loaned zombie little companies. Now they are just loaning them because they can't mmmh...right off the non performing loans and keep going with the zombie landing (same that happened in Japan). Because of it, they stopped the landing for others. What do u think about it? PS: im not english and not use it in the econ world that much ahah hope my message is "understandable"

I haven't studied Italy much but the story sounds somewhat similar to what happened in the US. In the US, the Fed began paying interest on reserves, which changed the banks behavior. Typically banks will hold reserves close to the minimum reserve requirement. After interest was being paid, they held far more, meaning that while money was being created, it wasn't being circulated. Whether you say that behavior is V decreasing or not depends on how you measure M. In some measures of M, reserves don't count, so if the money stays in reserve M doesn't budge. -Roman

May I ask where the number 7 for V came from? I looked it up and found it is closer to 2 fred.stlouisfed.org/series/MZMV Also if Y increases and we assume that M&v stay the same then that will lead to P falling. i.e. the deflation. Is this really true? An economy grows the price level falls. That seems to contradict logic. Any thoughts would be most greatly welcomed.

It's the increase in prices that cause the increase in the money supply, not the other way around. Prices reflect our demand for money. Prices increase because we demand more money, and the more money we have, the more money we demand. Because when having money is no longer about survival, it becomes all about status, which makes people insecure, causing people to desire more money. The solution is to recognize that if goods are easily made plentiful, then it barely cost us any resources and labor to provide for each other, so the prices should reflect that...free.

So what if we restricted the money supply and made it static, unable to change? Would that eliminate inflation?

This is a good video in many respects, yet ultimately it constitutes bad pedagogy because it does not mention, let alone consider rival theories of inflation. For example, most Post Keynesians would argue that inflation usually starts with an increase in P and this cause M to increase in response. In other words, the causation of inflation is the opposite to that argued for in this video. The Post Keynesian theory is realistic For example, a wage-price spiral is an obvious example of price increases being generated via distributional conflict. Furthermore, a government and its reserve bank have trouble measuring the money supply let alone controlling it tightly and its entirely reasonable to argue the M could expand in response to P.

Is there empirical evidence that supports the Post Kenynesian's theory of inflation?

@tbthornton5305

2 жыл бұрын

Thanks for your reply. Yes, there is good empirical evidence that inflation can (and does) run from P to M (rather than from M to P). However, let me start with the basic theoretical logic. A Post Keynesian view rests of inflation rests on the idea that the money supply is endogenous (as opposed to the essentially monetarist view of inflation in the video above, which assumes an exogenous money supply - i.e. that the money supply equals the money multiplier times the monetary base. Since the central bank can change this base, it is assumed that the bank can control the supply of money in the economy = exogenous money). Once it is realised the money supply is actually endogenous then it much easier to grasp how the money supply is accommodative of (rather than determinative of) a rise in prices. The pressures for such a rise have multiple origins, for example a wage-price spiral. In terms of evidence, see analysis of panel data from 177 countries in Nayan, S, Kadir, N, Abdullah, MS & Ahmad, M 2013, 'Post Keynesian Endogeneity of Money Supply: Panel Evidence', Procedia Economics and Finance, vol. 7, pp. 48-54. See King J (2015) An Advanced Introduction to Post Keynesian Economics, and its bibliography, for both further theory and evidence on this point (and many other important points in macroeconomics and finance).

Has the Post Keynesian's model for inflation done a good job of explaining the recent surge we are seeing in the US and UK? Our current situation should be a good test as to whether that updated model is any good.

If inflation is directly affected by money supply, would stoping production of new money solve it? I hope somebody can answer, I just want to understand the concept of inflation. I live in the Philippines and the news says that inflation is at 6.4% it's highest for almost a decade. I know that this means higher prices, but what could've caused this? And what the government did or didn't do to end up with this. (I think one recently passed law may have contributed but I'm not sure).

In the equation GDP = C+I+G+(X-M), does investment 'I' includes inflow of Foriegn direct investment (FDI) ? Does investment 'I' includes spending by domestic businesses only? Does investment 'I' includes spending by foreign businesses in the form of Foreign direct investment (FDI) ?

People seem to underestimate the velocity change during covid.

Assuming the initial equation is indeed an identity, then we are left with an equality relating two variables, P and M, as we don’t know anything outside of P being called “prices” and M being called “ money”, we only now that when one moves, the other follows. If we assume that money is set first, say by the central bank, then it should follow that the price moves accordingly. But, if we assume prices are set first, then it could be that the central bank reacts accordingly by providing the necessary money. If we don’t make one of these explanations before presenting the equation, the equation has no power of explaining the process. The explanation must be presented before the equation, and the equation is a result of the explanation, not the other way around.

so maybe this is another "relatively flat" factor, but doesn't supply of products also matter? like that's basic supply and demand what am I missing here?

I see, demand (V) and supply (Y) are low during recessions. So that's why they have to pump cash to inflate and stimulate demand and supply again.

you say "In the long run, a doubling of money supply leads to a doubling of prices" but in the long run isn't Y (PRODUCTION OF GOODS AND SERVICES) also changing ?

Can you explain same theory about INDIA

an increase in the money supply is not caused just by printing money by the Central Bank. It can also increase when commercial banks issue too much credits and debt. Or when immigrants/tourists bring money from other countries.

So what you are saying that inflation is primarily caused by an increase in the money supply.

Can anyone explain why inflation keeps rising? Shouldn’t it stop once total spending matches the total money supply? How can consumers keep bidding up the average price of goods if every dollar has been allocated?

What if money supply is increasing but the money doesn't get spent on final goods but goes into asset markets, stocks, bonds, real estate. I don't think this equation captures inflation in assets.

All to prevent the buble from bursting but its just a matter of time. Order > chaos.

What if prices rise because of rising price on commodities,caused by lower supply of commodity.Isn’t that non-monetary changes in price?

what if M is constant? like in bitcoin. if v and y is relatively constant in long run, and M is made to be constant, then P is also constant?

Yes - given that Y also typically is growing, you could have a mild deflation in M is relatively constant.

When we would purchase goods from other countries, Y would grow, and then M would decrease to cool off the economy, and in turn that would enrich the country we were trading with and everything would balance out in the end. Mild deflation is a small price to pay to keep governments from deficit spending.

MCOD1999 For that matter, it is also possible for Y to change very rapidly. For example, natural disasters or wars can cause sudden falls in Y due to destruction of real productive capacity. Y can also rise suddenly in exceptional circumstances (change in national political regime, end of natural disaster like plague, etc). M is the driving factor behind inflation under normal circumstances, but not all circumstances are normal.

Central banks alongside with commercial banks working on fractional reserves creating money out of thin air. More money chasing the same or fewer goods. You are welcome.

Tabarrok lies at 2:39 when he turns an accountant identity (MV=PQ) into a causal relation. Prices may go up due to an external supply shock, for instance, like bad crops or oil price rise. Surely, monetary supply must accommodate for the inflation to take place without collapsing the economy but it is not the rise in M but the rise in basic or import prices that ultimately causes the rise in prices; additional money supply is in this case but a coadjuvant factor. He's trying to cheat also at 5:45 when he states that in the long run money supply is neutral. What about additional money supply decreasing interest rates, hence increasing investment, GDP, employment and capital stock? Tabarrok is just conveying another neoliberal fallacy: he's assuming that Y, the real output, stays unchanged, which need not be the case at all. The ill-defined expression "in the long run" is used to conceal the function of monetary policy in order to take the economy to the full-employment GDP.

Also, if you deny the existence of the short-run and the long-run you show yourself to be a complete ignorant of macroecon 101. In the short-run the prices of resources stay the same, in the long-run they don't because you cannot expect inflation not to have its effects on costs of production. You are full of crap.

I took this as an introduction to the concept. Simplified for people like me to make it easier to understand.

The fallacy with this video series on Economic Theory is that it ignores the effect of extreme economic (and political) inequality. The argument that price inflation leads to wage inflation is completely false, at least for those paid a minimum wage. The $7.25/hr minimum wage is the same today as in 2009, even as corporate profits have soared, and as fewer people now work full time or receive healthcare and retirement benefits. For those people living paycheck to paycheck, the speed of money is very fast, as they tend to spend it as fast as they get it. But for those with means, the speed of money is far slower, because they can afford to sit on it or invest it. So, with that perspective, this entire series seems to have been created by the wealthiest 1% to spread disinformation and nudge policy in the directions they prefer.
