This research examines the influence of consumer regulatory focus on preference for product bundles. Product bundling is a type promotion in which multiple products are combined as single comprehensive package, commonly accompanying with price discounts. focuses non-variety bundle that includes units same item and variety composed different vary terms ingredients, taste, or flavor, It hypothesi...

Paramyotonia congenita was first described by Eulenberg (1886). It is a rare, hereditary disorder of muscle in which severe loss of power is induced by degrees of cooling which are insufficient to affect normal muscle. Myotonia also appears on cooling. However, the paralysis produced by cooling distinguishes paramyotonia from Thomsen's disease. The weakness and myotonia can easily be produced u...

Unlike most other agronomic crops, the selection of a bermudagrass cultivar is a long-term commitment. Bermudagrass is a warm-season perennial grass that can persist and withstand the rigors of grazing and hay production for decades. Establishing it, however, is a significant investment that pays off over the long-term. It is important to understand the characteristics of the different cultivar...

Since the industry revolution, companies have tried to standardize more their components, in order to allow mass production and to increase components’ commonality between products. To remain competitive, companies always have to offer more variety to customers. Manufacturers of complex assembled products that are facing the challenge of mass customization are forced to increase simultaneously ...

Standard approaches to measuring the welfare gains from variety take variety as exogenous to consumers. Empirically we observe an Engel curve for variety, with richer consumers purchasing a larger set of varieties than poor ones. I present a tractable model for analyzing the welfare gains from variety in the presence of this non-homotheticity. The model generates variety Engel curves through di...

Task variety is a familiar concept in organization theory and in job analysis. Standardized scales to measure task variety have been developed and shown to be reliable, but results reported here suggest that while these scales may measure the number of different tasks performed, they do not measure variety in work process. Comparing results from the standard, survey-based measures and detailed,...

Retailers need to decide on the content and structure of their product assortments, and thereby on the degree of variety that they offer to their customers. This paper compares measures of assortment variety and relates them to underlying variety components. We conceptualize assortment variety from a product and an attribute perspective, compare extant measures of assortment variety, and examin...

The notion of partial plans has existed ever since the early days of planning research. However, plans can be partial in many different ways, and for many different reasons. This paper presents a characterization of partial plans and discusses the use of partial plans in incremental planning under computational and informational constraints. A heuristic for guiding the generation of plausible p...
