Incentive Design on Networks (with A. Daripa and S. Kapur)
We design a mechanism for network formation with privately known productivities that implements the socially optimal network through transfers based on opportunity costs, ensuring ex post incentive compatibility, pairwise stability, and budget balance.

Network Structures and Credit Rating (with A. Daripa and S. Kapur)
We study whether productivity-consistent credit ratings can be inferred from endogenous network structure, showing that under suitable link costs equilibrium networks separate types and sustain ratings aligned with productivity.
