I was thinking about a theoretical economy where there are 3 types of roles for the agents. They can be :
workers : produce good A criminals : steal good A cops : protects good A
without going into details, are they any theories around this type of economy and the different types of equilibrium that can be achieved, using different characteristics for agents, different rules etc...
This idea came from the fact that raising productivity could have perverse effects (raise criminality in this case) given certain conditions.
Also, do you have any tips on researching among existing economic theories for something that will describe an idea that you might have,
