Recent food safety events have raised concerns about adoption of traceability systems. The paper studies the question of when and why a supply chain should invest in an upstream traceability system that allows identifying which supplier is responsible for quality defects due to insufficient...

This paper studies the divergence in the planning and equilibrium solutions for a multicell aquifer with heterogeneity in cell depths. A spatial model is developed that explicitly accounts for the lateral movement of water between cells. The optimal planning problem maximizes the discounted...

In this paper we study incentives to report clinically suspect situations in a simple model of an infectious animal disease with limited diagnostic resource. We characterize a transfer scheme that sustains credible reporting and implements an efficient test allocation. In a game without monetary...

Recent food safety events have raised concerns about food traceability in both developed and developing countries. In this paper we study the decision to adopt a traceability system in a supply chain with repeated upstream and downstream moral hazard and imperfect consumer monitoring. In...
