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...

Farm size is a significant determinant of both groundwater irrigated farm acreage and groundwater irrigation application rates per acre. This paper analyzes the patterns of groundwater exploitation when resource users in the area overlying a common aquifer are heterogeneous. In the presence of...

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...

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...

We study optimal disclosure of variety by a multiproduct firm with random costs. The prices for labeled varieties are increasing functions of the cost differential and do not reveal which variety is cheaper to produce. Nondisclosure is most common under moderate uncertainty about costs and not...

This paper analyzes a game theoretic model of groundwater extraction in an asymmetric two-cell aquifer under incomplete information about the extent to which the local stock of groundwater depends on the extraction histories at nearby wells. A novel assumption is that the elevation of the bottom...
