Why bring nasty ugly economics in to a game that is meant to be fun? Why double down on broken economic models when the sky is the limit in a virtual world where solutions to problems don't need to leave anyone out in the cold? If the market has an inflation problem, why not use a model which is inflation-proof?
And remember! Not real world economics. Be creative. Imaginary world means we aren't restricted to depressing reminders of real-world financial ruin. This is a question about game development.
