Multi-karma economies for coupled resource allocations
We recently developed the concept of karma economies as a non-monetary solution to the allocation of shared resources such as roads, energy and bandwidth. Thus far the focus has been on single resource allocation domains, for which karma economies have shown promise in achieving the traditionally conflicting objectives of fairness and efficiency. However, in many contexts the allocation of one kind of resource has direct consequences on the utilization of other resources. This presents both an opportunity and a challenge. The opportunity lies in added flexibility to devise social incentives, e.g., incentivizing EVs to charge during the traffic rush hour could alleviate that traffic, commuters could be willing to accept slower travel routes in exchange for convenient parking, etc.. The challenge lies in preserving the fairness and efficiency properties when interconnecting multiple karma economies, especially considering that end-users could have heterogeneous private preferences for the different resources. So while incentivizing a certain kind of resource consumption over another could be desirable overall, it could come at the cost of disfavoring some groups.

Your task will be to a) review the existing game-theoretical formulation of karma economies in single resource domains, b) extend this formulation to multiple resource domains, c) develop software to compute Nash equilibria in the extended game, d) using real-life inspired use cases, empirically validate the fairness and efficiency properties of different schemes to interconnect multiple karma economies, including when karma of different resources is not interchangeable, fully interchangeable, or interchangeable at an exchange rate, and e) investigate the effect of preference heterogeneity and the optimal design of the karma exchange rate.
