That's a good question. So efficient price is always a snapshot of the current supply and demand. It's easier to think of this at more encompassing than the individual purchase but all the purchases occurring in the market.
Say I have 100 seats in my theater and I'm selling tickets for $25 dollars. But there are over 100 people that would pay $50 dollars to get those seats. I'm immediately creating an arbitrage because a lot of people might want the ticket at $25 dollars but would immediately sell it for any price above that. So eventually the tickets would be sold at $50 dollars because those people who would pay $50 dollars will buy it from the people who got it at $25 and I'm just creating a secondary market where I don't get the profits.
Anytime a resale market exists it is because there is arbitrage and it would be more efficient to just sell it for the correct price of $50. A good indicator of an underpriced product is if there are bots farming for it to resale it. I hope that helps. There is a really good book if you are interested called Who Gets What and Why? that's really good. That goes more into how markets work.
I've personally lost family to acute renal failure and feel your pain.
The way you describe help from your family makes it appear that you are not aware of "kidney chaining" and the kidney exchange process.
If you have a family member who is willing to donate a kidney, it doesn't need to be a match for you. It just needs to match the requirements of a chain.
Alvin E. Roth researches and works with industry on improving the availability of organ transplants using market design. He is one of the pioneers of kidney exchange. He continues publishing research and has published a book for general public consumption. To begin with, this book would help give you an overview: https://www.amazon.com/Who-Gets-What-Why-Matchmaking/dp/0544705289
Stay strong, friend. You will make it.
> name one that has it
https://www.amazon.com/Who-Gets-What-Why-Matchmaking/dp/0544705289
if you even googled his name, it comes up. is google too hard for you?
> Also extra LOL at citing "the reddingtonpost" as a credible source.
um, did you actually read the article? they took the image right out of the worldbanc report. and linked to it. something doesn't become false just because it doesn't fit your biases.
> [all the rest of the shit you said]
again, you did not present even a single counterpoint. all you did is complain about what i said.
Not sure if this would qualify but I really liked https://www.amazon.com/Who-Gets-What-Why-Matchmaking/dp/0544705289 for a really accessible introduction for auction theory and mechanism design.
