We develop a model of household demand for frequently purchased consumer goods that are branded, storable and subject to stochastic price fluctuations. Our framework accounts for how inventories and expectations of future prices affect current period purchase decisions. We estimate our model using scanner data for the ketchup category. Our results indicate that price expectations and the nature...

Sensory science is a scientifi c method used to “measure, analyze, and interpret human responses to products as perceived through their senses of touch, taste, sight, smell, or sound.” Sensory science is often used to improve existing products or to test people’s views on new products, such as the softness of tissues, the crunchiness of an apple variety, or the aroma of air fresheners. It is al...

We present a method to estimate demand parameters in the presence of unobserved choice set heterogeneity that is related to Chamberlain (1980)'s Fixed Effect logit. We rely on assumptions about the stability or evolution of choice sets over at least two choice occasions to difference out unobserved-to-the-econometrician choice sets and to consistently estimate preference parameters. We present ...

A screening life cycle assessment (LCA) of tomato ketchup has been carried out. The purpose was to identify ‘hot-spots’, that is parts of the life-cycle that are important to the total environmental impact. The system investigated includes agricultural production, industrial refining, packaging, transportation, consumption and waste management. Energy use and emissions were quantified and some ...

This research is one of the diversification efforts food substances to create economically valuable nutritious food. It has been researched use isolation protein from waste Ketchup Industry as mixture crackers with various comparisons between isolating and cassava by adding an extract carrot about its nutrient content also. The analyzing using Kjeldahl method turning dust β – carotene spectroph...

Many robots are designed for use in domestic environments where robots will be engaged in household chores. The robots need to learn ways to do the household chores that humans are now doing. We are taking a learning from demonstration (LfD) approach to this problem [1]. In terms of the household chores, a number of tasks are developed so far; for example, bringing a beer bottle from a refriger...
