This paper presents a dynamic principal-agent analysis of incentive systems for Salmonella control. The European Union will require Salmonella testing from 2008. On the basis of the producer's performance history in controlling Salmonella, the incentive systems analysed determine quality...

Research on low-income household food costs shows that the poor often have limited shopping opportunities and pay slightly higher prices for food. It is often hypothesized that higher prices are due, at least in part, to higher operating costs for stores that serve low-income households. This...

Some hypothesize that poor consumers pay more for food because stores that serve them have higher costs. We assess how supermarket characteristics and operating costs differ with the percentage of sales from food stamp redemptions. Results do not support the hypothesis that costs are higher for...

Collaboration and advanced information technology are considered essential for successful supply chain management. The effect of supply chain factors, along with store characteristics, market characteristics, and competitive position are considered upon performance measures for sales...

Dynamic programming models with continuous state and control variables are solved approximately using numerical methods in most applications. We develop a method for measuring the accuracy of numerical solution of stochastic dynamic programming models. Using this method, we compare the accuracy...
