I do apologise for the length of this post. People are welcome to scroll past it. But I was challenged.
You never mention inflation?
I have mentioned inflation many times.
Funnily enough, if you look at individual inflated sectors an interesting picture emerges.
Basically, what is called 'money printing' is the creation of money through credit. House price inflation is an area of concern to many, especially the young who can't afford to purchase houses.
House price inflation can be traced to the entry of commercial banks into the mortgage market. Remember, bank loans are pure money creation done by banks 'crediting' the accounts of those they lend to.
In the past, loans for house purchase were transacted through Building Societies. Building societies couldn't create new money, they had to make loans backed by deposits from their savers. Once the banks realised that mortgage loans were highly profitable for them they entered the mortgage market in a big way. And many Building societies became banks so that they could compete with the banks in creating new money when they made loans. The availability of all this credit (new money) pushed house prices higher and higher. The Global Financial crisis was a consequence of banks extending so much credit to all and sundry, even people who couldn't really repay what they owed plus the inevitable interest, that the system was almost collapsed as banks didn't have enough reserves to cover the bad debts. At this point governments bailed the banks out (because the failure of big banks would have wiped out many people's deposits with them) and so the banks went on extending credit and house prices continued to rise to levels which are unaffordable for many.
Of course, the shortage of housing in the UK doesn't help as that leads to another cause of inflation. When there is too much 'money' wanting to purchase a commodity in short supply the price rises and the commodity is sold to those who are willing to pay the most for it.
House prices aren't actually included in the 'basket' of items used to calculate inflation figures, but nonetheless, it exists and has adverse effects. What you do have to note is that state money creation plays no part in this.
So, inflation can be caused by too much money chasing commodities in short supply, but an allied cause is the sellers of commodities in short supply deliberately increasing prices to increase their profits. As we see with oil prices following the war with Iran.
The standard response of central banks to any sort of inflation is to raise interest rates with the aim of cutting consumer spending, the theory being that it is consumer spending which causes inflation and less consumer demand will lead to lower prices. Unfortunately, increased interest rates tend to lead to increased prices in some sectors, oil being again the prime example today. The increases in oil prices feed into increased energy costs and eventually increased costs for businesses which lead to them increasing their prices to cover the costs. But the increased interest rates meant to lower inflation actually add to inflation by increasing the cost of credit for everyone who uses it, that'll be businesses and consumers alike...
Once again, this inflation has nothing to do with state money creation...
State money creation causes a inflation problem if there are not enough resources within the state available for it to purchase. If you look at the often quoted countries which experienced hyperinflation you will see that it was caused either by lack of resources within the state ( Zimbabwe) or a very high level of foreign debt (Weimar Germany and Venezuela) often exacerbated by a shortage of resources.
Inflation is measured by price increases over time. If a price increases once, then stabilises, the inflation measure will diminish over time. This is generally the case with external supply shock prices. Increased money supply will actually help to accommodate the price increase. Increasing the money supply to accommodate internal resource shortages will only make the price inflation worse (e.g housing in the UK) Using interest rates to suppress inflation caused by resource shortages tends to increase it and it affects the poorest people the most. The wealthy can absorb the price increases, the poor can't.
The fairer way to control inflation, IMO, is to increase taxes to destroy the excess money, but to increase them on those best placed to absorb the increases. So, although a government might be increasing the money supply by spending new money, it can more equitably mitigate the increase if need be by targeting its taxation.
It's all a bit of a balancing act, but running an economy is just that. It has to refine its instruments with regard to the welfare of all the population.
I can assure you that MMT proponents care a great deal about inflation. They just propose different ways of dealing with it.
I'd say again that we have experienced two very significant episodes of overt state money creation in the last 20 years. The first caused asset price inflation, mostly for the wealthy but not for the 'ordinary' populace; the second paid for Covid and kept the economy going. That didn't cause any notable general inflation.
And with so many of our public services running down and a high level of unemployment (over 1 million) we can hardly say that the UK is short of resources to purchase to improve this.
