If the effect of losing Deal is everything you purchased with Midas Money will be gone, why not not using Midas Money at all?
Because that doesn't appear to be how it works. You're betting your future. You do not lose what you bought with the money, you lose a portion of your future. For the people who spent money? They lose what it gave them. For people who didn't/ don't have enough to lose? It takes more. As can be most clearly seen when Yoga fails a class, despite the fact that there's been absolutely no change in his lifestyle from the money.
If someone wouldn't use Midas Money at all, then they wouldn't become an Entre in the first place.
Could Kimimaro's asset gain weight from eating too much ramen?
Well, she burns a lot of energy fighting battles. So, I doubt it.
Yoga's Father and Bankruptcy
What did Yoga's father lose when he went bankrupt?
If you enter the Financial District and are given the initial start-up loan with your future as collateral, why doesn't anyone attempt to pay back the initial loan after doubling it or more? Theoretically, this would allow you to use the Financial District without further risk, even if you lose a deal or go bankrupt.
Ignoring the fact that the Midas Bank doesn't play fair, you'd also have to return your Asset.
Giving Away Assets
If someone who goes bankrupt has lost their future, how can their Asset still be functional if someone else has it?
My (speculative) interpretation is that it becomes a "possibility" for the new owner - like how Sennoza describes wins and losses in Episode 6. The bankrupt entré still loses their future, but Midas Bank repossesses the money from the sale, rather than what's left of the future itself (which has already been sold off).
Economics of the Ending
Economics question: Kimimaro essentially saved the Japanese economy with a currency devaluation. Isn't devaluing the currency to pay your own bills exactly what Mikuni was doing?
To me the main difference (aside from the obvious cost of deliberately pawning future possibility for cash) was that, as per his discussion with his inner circle in Episode 9, he was trying very hard to hide the fact that he was bloating the money supply (although some inflation still occurred, obviously). In contrast, Kimimaro, Jennifer and Takedazaki used their currency to deliberately destroy confidence in the yen - not to pay their own bills, but to make their bills a moot point.
I assumed, considering, that Kimimaro/Jennifer were using DOLLARS as their currency. Plus, they didn't have as much money tied up in the economy as Mikuni. And, thirdly...the SOURCE was different. (Real world money, not Midas money).
If we're talking about economic analogy, Mikuni was using deficit spending—costing the "future" of the country. The hyperinflation was monetizing the debt. This is arguably the best solution when a nation has truly gone bankrupt. You don't have that option for places like Greece because they don't have control over their own currency.
Reversing the Mint
What happened at the end? If all they had to do to restore the future was run the mint in reverse, why wasn't the plan to just sell the future when C comes, then reverse the mint when it's over? Why did C bounce off America? Why did it pass through Japan? What will happen to the place it hits next? Is everyone going to learn from Japan's example and copy them?
The C passed through America because it has its own, extremely powerful Financial District, and was able to largely ignore the effects. The C is a metaphor for a worldwide recession, so Japan (and any other countries it hits) will dry up faster.
Passing on a Deal
If you pass on a deal, you lose half of your fortune. You need this money because it helps you win deals. Why not just pass every time?
You still have to fight at least once a week.
You can teleport in the Financial District. Do you have to leave where you entered? Could you just start a courier service where you use the Financial District to send packages around the world with ease?
In theory? Probably. But the Midas Bank probably wouldn't allow it.
Do the flations have anything to do with the economic concepts they're named after?
Mikuni was propping up the economy by buying Japan's debt with Midas Money. Isn't the result pretty much the same as if Japan payed the debt by printing money or raising taxes?
Yes. You need to understand that the entire series is an austerity Author Tract, where debt is always bad, and creating more debt (which is what Mikuni was doing, by using loaned money to buy up the debt) is even worse. That's...not quite how economics really works, as evidenced by the fact that Japan has a relatively strong economy (compared to the rest of the world) despite its massive debt.
Midas Money conservation
Is Midas Money conserved in a deal? It doesn't sound like it from the description. When they talk about one entre losing money, does that mean it just goes to the other entre?
Some of it goes to the other entre if the diagrams in the background are right. But the money they use for the flacions goes to the bank.
Gaming the Deals
Why don't people give someone else all but one yen before a deal, and have them give it back through buying a share of their asset once the deal starts? That would ensure that anything short of bankruptcy would count as victory.
Why does the information broker act crazy? That is not generally a good way to ensure confidence.
...because he's crazy.
What happens if neither entre does anything during a deal and it ends the way it starts?
It would probably be considered a double loss, and both entres would lose half their money as if they passed (which they did, basically). This is why Jennifer tries to keep her wins and losses to a minimum (i.e. around 51-49).
Where does the money come from?
Where does the money the entres are loaned at the beginning come from? Are the mints running constantly for this?
In all likelihood, yes. Real life mints have to run pretty much constantly just to account for lost or destroyed money. Midas has no problem with injecting cash into their economy at random intervals. Or maybe that's why they choose new entres: A large amount of cash has been lost for whatever reason (suicide by someone with money left over, for example), and they need more quickly.
Mint in reverse
How were they feeding Midas Money back into the mint? Was it just taking money from everyone?
That was the implication, yes. They were destroying all of Japan's Midas Money.
