Imagine a world in which large % of El Salvador prices are actually posted in BTC. Tradable goods would fluctuate between stupid cheap or expensive depending on BTC prices
Suppose you build a car in US and want to sell it for $30k USD in El Salvador. You set the price at 1 BTC. Your offer effectively functions as an outstanding BTC put. At any point in time, buyers can "sell" you one BTC for a car. BTC goes down and you are out a lot of cars!
If your tradable goods price is essentially long vol, what do you do? You perhaps price the vol into the contract, setting the price at say 2 BTC to make enough profits to cover the price movements
Or when BTC prices move too much you could conveniently "oops! all our cars are sold out"
Or you could simply have (assuming govt allows this) an equilibrium where all tradables at least are priced in e.g. USD or something. Anyways, if this goes ahead, it could be interesting to watch...
Even funnier, as was discussed on here a while back, _return policies_ become super weird with volatile currencies. Sell a bunch of cars in BTC, BTC values go up, suddenly a lot of people aren't happy with their cars and want their BTC back...
All this depends on how sticky prices are of course. Moreover, firms can hedge out much of this risk if they want! There are now many semi-liquid (though also some semi-legitimate) BTC derivatives markets, your car factory can in principle just swap out the risk and go to sleep
And from the perspective of El Salvadorian citizens, life is also weird. You hold a bunch of tokens. Perhaps prices of services, etc. stay relatively stable in BTC terms. But your purchasing power for intl goods/services fluctuates like crazy month over month
A more speculative thought. I have no idea how to model this, but I wonder whether the kinds of goods flows in/out of the country due to BTC/USD shifts would tend to stabilize BTC/USD, in some sense?
Or... the El Salvadorian central bank presumably couldn't defend BTC/USD even if it tried. But if enough countries did this, and in a sense acted in concert to trade to stabilize some BTC exchange rate, could we actually reach a relatively stable BTC/other-fiat regime?
Perhaps this would look something like the old gold-standard days, except rather than ppl trading in-principle-gold-backed fiat, ppl are literally trading tokens they own, but CB's do some occasional semi-concerted big interventions to try to stabilize prices?
Anyways, this is mostly sci-fi-(nance?), but it's an interesting situation to think about!
This. On the bright side: while intl students face a strong language barrier, I think they mistakenly assume there is also an insurmountable _culture_ and institutional details barrier, which I think is a bit smaller than it first seems.
I've found intl students tend to shy away from subfields which are very institutional-details heavy, and towards technical subjects not requiring much details. I think partly because they assume American/Western students know all the institutional details
Details like, how does the US healthcare/tax/electricity/financial etc systems work. The advantage here is actually IMO fairly small. The median international student knows ~0 about these things, but so does the median American college graduate!
Here's a thread I wrote a about the paper a while back. The new version has some new results on revenue, some more numerical simulations, and is slightly streamlined, but otherwise is pretty similar
1.9% for sellers seems kind of insane?? That's like not much better than credit cards!
Blockchain is obviously still a generally stupid medium for transactions AFAIK, but it makes a lot more sense once you realize how hilariously awful the US payments, etc infra is. Imagine paying 3% for any transaction at any merchant ever
There is a surprisingly simple "hack" to doing well in college classes, even fairly hard ones. Say you want to do well in intermediate physics, chemistry, math, etc. Just find every textbook written about your subject, read and do/figure out the answers to all the questions
This works in my experience because it's pretty rare for faculty to come up with test questions literally out of nowhere: often they're taken from other books. Even if they are "new" someone's often come up with the same thing before and it's in a book somewhere
There are realistically only so many good test questions one can ask about intermediate physics, and it's entirely possible (though tedious) to get through most of them
Automated market makers seem like a good tool for videogame economies. Say there is an in-game resource called, ruby, or something. NPC shopkeepers could deterministically set a price for rubies based on current inventory: lower inventory, higher prices
A few benefits of this:
- The NPC shopkeeper actually keeps a book and makes a profit, which could enable some interesting in-game behaviors (let's bankrupt the shopkeeper!)
- For resources that have stable/quickly mean-reverting in-game value the shopkeeper basically steadily profits from bid-ask spreads, like stablecoin pair market making
