Re: Show HN: A central bank simulator game with a realistic economic model
#2I made this game in order to try to wrap my head around central banks, inflation and macroeconomics, in order to get a better understanding of the aftermath of the global financial crisis and the current period of high inflation.
Here is a blog post that goes into further details: https://benoitessiambre.com/simcb.html

#3Pretty cool and interesting, good work :)

#4I have no idea if this was a bug or a failure model but it seemed I was doing decent until everything started failing all at once. Orchards running out of business etc.
LE: I tried another round. Put the interest rate at -0.5 and just left it there.

#5Cool stuff. It would be interesting to have a simulation with three levers: interest rate, taxes, fiscal spending.
But in the end, the problems with most such models is that the outcome ends up being determined by the assumptions built into the model.

Well, indeed, that was a huge problem with Sim City. They believed cities should have low tax rates, so of course low tax rates are the correct strategy. They also discovered exactly how much space building parking takes up so… they made cars take up no space rather than have a game in which public transport and cycling was the go-to approach.

Same thing here.

#8In reality of course central plannners 'pulling levers' and setting prices never works. The interest rate is one of the most important prices of them all, which is why having the government meddle with it has proven so destructive.

If you hit too much disinflation/deflation things can go sour pretty quickly. This is a bit exaggerated in this model as there are only 10 businesses and there can be a domino effect as 10% of the economy fails at a time. You can prevent it if you manage to counter deflationary pressures fast enough.
It helps to slowly creep up interest rates up when the economy is going well so you have more space to lower them aggressively during shocks.

Cool project, congrats on putting it out in the wild.

Iirc, it was a matter of < 10 months from good to gutter.
