This was made me laugh. So many times I read ‘it should then be obvious that…’ What the?! No it isn’t. Text book authors must hate students.

The confusion comes from the differences in what words like 'obvious', 'trivial' mean in Mathematics and what they mean in English. Same deal with the word 'significant' in Statistics and English.

I used to take swipes at Haskell and Category theory folks for their use of their ektomorphisms but later realized the point of using words that are not used in regular English.

In mathematics obvious/trivial means no new math or technique needs to be invented to go from this step to that step, it does not mean it would be easy. This is fairly standard usage.

Honestly, the first lesson in economics should be that there is no such thing as endless exponential growth. This is a nice video that gets the point across: https://youtu.be/UI2Zs3QfzEI

Are you sure about it? I mean so far you could describe the success of capitalism with exponential growth. Now you could argue that the earth resources are limited, but who knows if we gonna stay here forever. The universe is quite big...

I know this is the mainstream, but all of this reads like total nonsense to me. 1. Price changes carry important information too. What if demand stays the same but price still goes up? It could there is too much money, or supply is constrained or a new tax was imposed in the chain, or something was banned or the market is simply inefficient. 2. Low rates are sign that money has been tight? Maybe in a world where rate…

Fair enough hahaha. I do think there's some room for common ground here.

1. Yes, absolutely. It would be due to a change in supply. Price controls, taxes, regulation, etc affect the price only insomuch as they affect supply and demand. It's a matter of definition: it's just as true in a market economy as it is in a non-market economy, or under market failure. Whether it's a useful framework is a different matter!

2a. So, interest rates are indeed determined by the market, with respect to open market operations right? The Fed buys and sells with a target in mind, but they certainly can, as you point out, fail to hit their target.

2b. This was a bit of unfortunate jargon: demand for "money" specifically means cash/cash equivalents relative to other assets like stocks/gold/real estate. It's not referring to wealth, although I do think the desire there isn't infinite: biological limits/post scarcity.

2c. And "demand" for money refers to the whole of the demand curve (and shifts in the whole of the curve). That is, how much of your portfolio do you want to hold in cash/equivalents at a given interest rate?

2d. Fed open market operations do target the whole of the economy: it's a ham fisted approach. Inflation affects groceries and gas, just as much as bank liquidity and such.

3. So, relative price change isn't inflation by definition, and market expectations of the interest rate path are priced in. Of course, there are plenty of relative price changes alongside inflation, but there's a lot more to the economy beyond open market operations. The Fed isn't able to specifically target say apples over oranges, hence ham fisted.

4. Sure, broad aggregates like NGDP don't include inequality or climate change, but that's a good thing because the Fed's job is limited to keeping aggregate demand (NGDP) on track. Of course there's a lot more to the economy, but that's beyond the realm of Fed open market operations. That is, I don't think the Fed is the right place to look for solutions.

5a. So money neutrality only says: a permanent 1 time increase to the money supply doesn't affect real GDP.

5b. Again, more jargon: "long run" is however long it takes for thing(s) to adjust (whatever it is: wages, rates, output, etc), and "short run" is just short of that. So as a unit of time, it depends on the good as well as real world conditions. The short run can go forever, market failure maybe. The short run can be zero, when things go according to market expectations and everything's already been priced in.

Sorry, a lot of that's non sequitur. But that's my point: I think the mainstream is a coherent and useful story, but it's not relevant in this context, hence total nonsense. To the extent that there's an upward trend in inefficient businesses or 'rich get richer, poor get poorer', I don't see how open market operations can be the culprit.

But yeah, I don't necessarily disagree with your overall impression of the Fed hahaha.

My monetary economics professor in grad school was teaching a paper and told us that when the authors claim it's obvious, that means it's not obvious. So he wrote out the derivation over the weekend and gave us a four-page, single-spaced handout with all the equations behind that single "obvious" result.

This is way off topic but hopefully it will get allowed because I think you have the expertise to help: It seems to me that the widely accepted practice of market stimulation by interest rate intervention has the cost of destroying price discovery. Also, that it is a primary cause of wealth inequality. These relationships seem to me actually obvious: push down DCF denominators and valuations go up, inefficient busine…

>It seems to me that the widely accepted practice of market stimulation by interest rate intervention has the cost of destroying price discovery.

The idea that low interest rates stimulate anything is a myth. If you believe in the idea that the financial markets should obey the real world, rather than the opposite (which is assumed by practically all economics), then interest rates must go down all the way to 0% as the market reaches saturation.

> Also, that it is a primary cause of wealth inequality.

The idea that one should raise interest rates in a stagnant economy will cause nothing but a redistribution from the working class to the owning class. Who do you think is working for those interest payments? The rich? Do they even pay enough taxes to service government debt? Do they pay the interest payments for the financing that companies need to operate? Do they pay the interest on consumer loans of the poor?

>These relationships seem to me actually obvious: push down DCF denominators and valuations go up, inefficient businesses stay in business and employ people digging holes.

>Meanwhile those who hold wealth see its value increase disproportionate to 'actual' worth and common people who hold little or none can afford less and less of it.

It's exactly backwards. Getting paid interest in a saturated market creates excess liquidity which floods the market and drives yields down everywhere. People start speculating because they have nothing better to do.

>It seems like a pretty direct policy of 'rich get richer, poor get poorer'.

Well, that's what interest does. If you have too much money you get more. http://userpage.fu-berlin.de/~roehrigw/kennedy/english/chap1...

>Worse yet, as I look at the world around me, it all seems to support my hypothesis. Tesla, spacs, NFTs, housing, blackrock & vanguard & gates buying land, etc. I could go on and on with examples.

Land speculation is an extremely old problem that has always existed. https://bibliotek1.dk/english/history/centuries-of-experienc...

>But the thing is, I got shitty grades in my college econ courses. It's laughable to me that all the highly educated people at central banks somehow haven't thought of this but I have. I'm being serious, I'm kind of a lazy idiot. By any reasonable measure, I expect that I'm wrong.

You're wrong and the central bankers are wrong as well but they have no other option which is why they do what they do. When you take money out of the economy by saving it, the money in circulation goes down. The savers think they should be paid interest to circulate the money. The thing is, savers can just sit on their money which means they can charge an interest rate that is not set by supply and demand. Central bankers think the missing money has to be replenished. The thing about interest is that the amount of missing money in the economy grows exponentially.

The obvious answer is to just tax the people who are sitting on cash. If they are lucky enough to find a borrower that wants to pay them 0% interest, then they get to keep their money. That is a real free market.

Saving in cash is akin to blocking a road and demanding interest is like charging a toll for anyone who dares to take that road. The central bankers build a new road next to yours and then you block it too, leading to endless road construction. Fine the person blocking the road and you won't need to do much else.

>Could you point me in the direction of some primary sources that address the relationship between interest rate intervention and price discovery? I've been told to pick up an undergrad macro text, but those all just seem to say "low rates = easier to get loans = mo' jobz" without any rigor.

I would urge to watch this video series instead: https://www.youtube.com/watch?v=UI2Zs3QfzEI&list=PL65E9E0867...

>Open market ops and other interventions are so common and accepted, the only other people I see complaining are precious metals schizos. Surely there's a theoretical foundation for the policy/practice.

Have fun treating the symptoms and then noticing, that your solution either delayed the inevitable or made things worse to the point that people start a violent revolution and then reintroduce the same system so your grandchildren can experience a revolution as well.

Here are other excerpts from that book: http://userpage.fu-berlin.de/~roehrigw/kennedy/english/

We tried austerity in the European Union. It worked (but only for Germany). The rest never recovered from the 2009 collapse.

Austerity does not work with the current money system because any deflationary effect of paying debts back leads to currency speculation.

Every dollar is like a capillary in your body. Taking money out of circulating is equivalent to blocking the capillary.

When you do austerity it's like getting multiple simultaneous heart attacks. The Austrian economists say just deal with the pain but I have a fairer proposal. Tax cash at 6%, then you can pay off debts. Anyone who wants to save can go to a bank and lend out their money at 0% or above.

>5. Mainstream macro says money is neutral in the long run, non neutral in the short run. This might be what you're looking for: the effect of short term non neutrality of money on relative prices across the overall economy.

That's only true if you accept war and revolution to be a mechanism for reaching equilibrium over the long run.

>2. Ask anybody on the street if they demand more money and 100% will say yes. Why doesn't the Fed increase the money supply for the random Joe on the street, but does so to cover unsustainable liquidity commitments made by banks?

The unsettling answer is that you would lose your job if they didn't do that and I don't mean because the chaos a bank collapse causes. No, I just mean that the money in circulation would dry up so fast, your employer won't have any money to pay you.

>4. A mockery of a feudal economy in a way. And this is where we are heading.

It's a feudal economy from the start, it's just that early on, most of the money is circulating in the hands of workers and once it stops it has to be borrowed from those that take it out of circulation.

>5. We can prove this one as being false. Money neutrality has never been demonstrated in the long term. In fact most forms of money ended up guided by politics, hyper-inflated the supply, was banned, price-controlled or otherwise collapsed due to some inevitable populist political decision.

Thanks, you are absolutely right. The problem, however, aren't the politicians, they have inherited a system designed to collapse on its own. It shouldn't be possible to take money out of circulation. Hyperinflation is effectively a problem of forced indebtedness. If the politicians had the option of refusing debt they would have taken it a long time ago.

As I said before, cash guarantees you a 0% yield on your investment, therefore money can be taken out of circulation with no loss to yourself but huge losses to people who are dependent on circulating money. They (including politicians) need the circulating money now, so they accept loan conditions that are not compatible with current market conditions.

The system will collapse one day, so why not let it collapse a few years later? It's only logical. Meanwhile anyone who wants interest rates to go up wants the system to collapse earlier than necessary.

>It's pretty funny how the Fed keeps telling us they look long term, inflation is transitory and markets will work it out in a few years without intervening. But when the repo market crashed they didn't wait "for the market to work itself out", they rewrote their whole rulebook and launched support facilities the same day.

As I already said, that money too will be taken out of circulation one day.

>By now it's clear they are making it up as they go and they are just dominating the system with increasingly excessive interventions into a self-exciting oscillation.

If you think the Fed is intervening, why are you not complaining about the people taking money out of circulation that force the Fed to do stupid things? Why does that not count as massive market intervention? If you had a 6% annual tax on cash the interest rate would have dropped to 0% in 2000 and the money supply wouldn't have to grow as much.

What I am really getting at is the dependence on growth. It's fine to have it but not to force it.

Econometrics is one of the most discredited branches of academics that exists. These were the people who were waving their models around in the early 1990s, trying to tell people that NAFTA would have no effect on manufacturing jobs in the United States. They also promoted elimination of Glass-Steagall and the deregulation of the housing market, resulting in the subprime fraud-based economic disaster of 2008. There's…

The problem with economics is that people make the assumption that money is primarily or even exclusively a medium of exchange. It's only since Keynes that everyone understood that it's not really true. However, if you were to tax cash with a 6% annual tax then the old classical period of economics would be quite relevant again.
