Consistent two-step censored estimation is applied to household demand equations for disaggregated milk and cheese products. The long-run advertising elasticity for total milk was positive, largely due to low fat milk; however the elasticity for cheese was not significant, and only shredded...

We empirically estimate the valuation of new carbonated soft drink products within a model of market value maximization. We show that equity value is an important consideration in the firm decision to differentiate or imitate in new product introductions. Our results indicate that...

In this paper we introduce a switching error correction model (SECM) estimator that allows for the possibility that price transmission between markets might vary during periods with and without physical trade flows. Applying this new approach to semi-weekly data on tomato markets in Zimbabwe, we...

This study examined the impacts of retail promotions on the demand for five brands of orange juices for a retail chain (referred to as Retailer X) and its competitors using the Rotterdam model. Results show that the combination of feature ads and displays had the largest impacts on retail...

We develop a valuation model based on conservation rules, and stochastic prices and inventories. Dynamic programming determines the optimal harvest amount. A hedge portfolio based on a resource reserve is proposed. The optimal size of the reserve is determined, as well as its value.

The importance of heterogeneity of animal attributes in livestock production is assessed. Preliminary results indicate that variance and skew measures of attributes may be becoming more important over time.
