Determine how long term contracts will be established between agents

[dean-krueger]

Is this something that agents will decide dynamically throughout the simulation? Is there a stochastic element to it? Is it something that users will define up front? Should users have control over whether it happens, or how likely it is that two agents will form long term contracts?

If agents decide this, how do they make the determination that a long term contract will be beneficial? Is there some threshold where all of a sudden everyone has long term contracts vs nobody has them, and if so how do we correctly balance that?
