If I know this, I suspect the IMF does too, and incorporated that into the report.
You’re comparing the concept of economy-wide inflation with the basic supply-demand economics for one item.
LMAO no. It's foolish to equate an individual selling a single asset like a car with businesses that can range from little niche supply workshops up to dominating whole industries. Pure laws of supply and demand only hold true under conditions of perfect competition, and much of what we call 'business' is about playing the meta-game - out maneuvering competitors financially, creating moats and other barriers to entry to keep competitors out of a market sector, using marketing to maximize product differentiation and shape consumer perception, leveraging regulatory complexity in one's favor or lobbying for it to be reduced in order to gain some cost advantage.
Real world markets are a lot more complex than the little toy ones used to explain fundamental economic concepts.
I demonstrated this with an example, where we know what caused a price change (supply chain issues for a substitute product plus increased demand) and know the distributional effect (higher margins for sellers of used cars). If we naively try to explain the price change based on the distributional effect, we would claim that higher prices were purely caused by increased greed. We know this to be false.
Look, perhaps companies really did become more greedy in 2020 and that's what has really caused inflation. Or maybe large amounts of stimulus caused increased demand. Or perhaps the war in Ukraine has caused supply chain issues which drives up prices. My point is that looking at the distributional effects of inflation is just completely disconnected from the question of what caused inflation in the first place.
At the very least, if you're claiming that we can figure out what caused inflation by looking at the distributional effects, can you provide some evidence, or some argument, to support that claim? Because I think my example demonstrates that common sense ("X benefitted from inflation, therefore X caused inflation") is not a good guide here, and if anything, the additional complexity of real markets works against you here - if we can't even explain inflation based on distributional effects in a toy market, what makes you so confident we can do so in the market as a whole?
No it’s literally greed. You can choose to not raise the price of your used car when you sell it. “Market price” is a hallucination that you can ignore. You’re not forced to go along with it. As you said, sellers of used cars didn’t have their cost increase, so what was the forcing function for price increases except greed?
Which brings me to corporate profits…
It's a powerful signal containing important information! You don't have to go along with it, but it may be beneficial to others if you do.
As an example, we bought a new car in 2019. We were planning to sell our old car but every time we were about to sell it, it came in handy - family came to town and we needed two cars, or it was nice to be able to go two places at once.
In 2020, prices shot up. Suddenly, it was worth it to sell the car.
Someone who valued it more than us got to use the vehicle. Was that greed?
You sold it because you could get more money for it. That’s what greed is - you chose more money. You could make the case that you weren’t behaving immorally -not everything in life has to be a charity- but you acted out of a selfish desire for more money.
I’d also argue that “value it more” is pretty flimsy. Yes in a shortage the buyer clearly needed a car and was willing to spend more to acquire it instead of waiting for prices to drop. But you clearly didn’t value it beyond the 2019 price based on your stated desire to sell then, it was just an inconvenient transaction.
If "following market price signals to decide what to produce and sell" is greed, then EVERYTHING is greed.
You make clothes on Etsy, and suddenly people will pay more for silver clothes because Beyonce tells her fans to wear silver. So you make more silver clothes, and sell them for more money to more happy buyers… greedy you!
You have a shelf full of books. One of them is signed by a famous author. It's cool to have it as a conversation piece. That author dies, and suddenly the book is worth enough to pay for some needed home repairs. So you sell it… greedy you!
Didn't they? Increased demand for used cars should mean that used car buyers are forced to pay more for the same car than they would previously. Maybe it's lagging by a bit, but I would absolutely expect that their costs would go up.
For example, in 2020 there was a huge increase in demand for used cars, and the price of used cars increased by ~40% within a few months. But people who sold used cars did not have their costs increase - they were, after all, selling an already completed product. The IMF would therefore estimate that between 2019 and 2020, ~100% of inflation in used car prices was due to margin increases rather than inflation itself.
This is obviously silly - the increase in prices was because there were too many buyers and too few cars, not because the owners of used cars suddenly because significantly more greedy overnight. It's the same with corporate profits. Inflation has distributional effects which are interesting to study, but we shouldn't confuse ourselves by claiming that the effects are actually the causes.
