The integrated production, inventory and distribution routing problem (PDRP) is concerned with coordinating the production, inventory and delivery operations to meet customer demand with an objective to minimize the cost. The particular PDRP that we consider in this study also involves heterogeneous transporters with non-instantaneous traveling times and many customer demand centers each with i...

In this paper we present the problem of designing a three level hub center network. In our network, the top level consists of a complete network where a direct link is between all central hubs.  The second and third levels consist of star networks that connect the hubs to central hubs and the demand nodes to hubs and thus to central hubs, respectively. We model this problem in an incomplete net...

We develop a structural model to analyze the effects of banning advertising on market equilibria and welfare in junk food markets. We consider the impact on demand and prices, and show how to quantify welfare effects when advertising might lead consumers to take decisions that are inconsistent with their underlying preferences. We use transaction level data on the potato chips market and find t...

We conduct a natural field experiment with over 200 customers at a grocery store to investigate dynamic inconsistency and the demand for commitment in food choice. Subjects are invited to allocate and re-allocate food items received as part of a grocery delivery program. We observe substantial dynamic inconsistency, as well as a demand for commitment among a non-negligible number of subjects. I...
