Sectional algebras of semigroupoid bundles

In this paper, we use semigroupoids to describe a notion of algebraic bundles, mostly motivated by Fell ([Formula: see text]-algebraic) bundles, and the sectional algebras associated to them. As the main motivational example, Steinberg algebras may be regarded as the sectional algebras of trivial (direct product) bundles. Several theorems which relate geometric and algebraic constructions — via the construction of a sectional algebra — are widely generalized: Direct products bundles by semigroupoids correspond to tensor products of algebras; semidirect products of bundles correspond to “naïve” crossed products of algebras; skew products of graded bundles correspond to smash products of graded algebras; Quotient bundles correspond to quotient algebras. Moreover, most of the results hold in the non-Hausdorff setting. In the course of this work, we generalize the definition of smash products to groupoid graded algebras. As an application, we prove that whenever [Formula: see text] is a ∧-preaction of a discrete inverse semigroupoid [Formula: see text] on an ample (possibly non-Hausdorff) groupoid [Formula: see text], the Steinberg algebra of the associated groupoid of germs is naturally isomorphic to a crossed product of the Steinberg algebra of [Formula: see text] by [Formula: see text]. This is a far-reaching generalization of analogous results which had been proven in particular cases.

Does the presence of variety matter for bundle evaluation?

We examined consumers' perceptions of, and responses to, variety in product bundles in 3 studies with Chinese university students aged between 17 and 29 years. In Study 1 (117 participants) we found that variety (vs. nonvariety) bundles were more attractive and more likely to be purchased, and this effect was robust across different variety formats. In Study 2 (89 participants) the mediating role of perceived hedonic benefits was supported, that is, participants responded to the level of variety in product bundles as they tried to maximize their hedonic benefit from the consumption. In Study 3 (74 participants) we further explored the moderating role of consumption goal and found that participants were willing to forgo an additional quantity to have variety, especially when their consumption goal was hedonic rather than utilitarian. Theoretical implications and practical implications for marketers are discussed.

Evaluation effects of bundle size and price presentation

Purpose Marketers often combine products in bundles to increase demand. Research has shown that itemizing the prices of the individual products in the bundle raises evaluations in some situations. The purpose of this paper is to investigate how bundle size influences the effect itemizing prices have on bundle evaluation. Design/methodology/approach The authors conduct two experiments. In the first, they test the effects of price presentation formats (itemized vs consolidated) and bundle size on consumers’ evaluations of product bundles. In the second experiment, they test the proposed mechanism that itemizing the price leads to a more realistic price expectation which in turn enhances evaluation. The authors also test whether this effect is stronger for larger bundles. Findings In Study 1, the authors find that large, but not small, bundles are evaluated more positive when presented with itemized prices. In Study 2, mediated moderation analysis supports the prediction that price expectation mediates the effect of the price presentation × bundle size interaction on bundle evaluations. The findings show that itemizing prices results in more realistic price expectations and that this effect is stronger for larger bundles. In turn, more realistic price expectations lead to higher evaluation. Research limitations/implications The implication of this research is that by directing attention to individual items in the bundle, consumers are better able to assess bundle benefits. More research is needed to investigate other potential explanations for the findings in Study 1. Further research should also investigate whether the findings reported here holds in other settings, with other products and with other types and size of bundles. Practical implications Managers are recommended to itemize the prices of product bundles, particularly when bundles are large. Originality/value This paper extends our knowledge about the effect itemizing the prices of individual items in a bundle has on consumer evaluation by demonstrating the moderating effect of bundle size and showing that more realistic price expectation explains these effects.

Suggested Marketing Strategy Using Apriori and FP-Growth Algorithms in retail sales in Egypt

Due to the increase of retail sales in Egypt and all over the world, came the importance for the managers of supermarkets to develop marketing strategy to maximize their profits, by getting rid of inactive products. Product bundling is one of the most important marketing strategies used to get rid of stock by making integrated bundles of inactive products and demanded products with discount prices. We can do that through our recommendation system and also increase customers' faith by keeping up with their purchase habits changes in low prices. In this study, first association rules are applied to find the best-integrated bundles with optimal suggested bundle size according to customer habits. Second testing these resulting product bundles to eliminate bundles didn't contain Products aim to get rid of them. Finally the given suggested bundles’ elements replaced with stagnant products that are the same kind of product in the bundle but with another trade. During that study algorithms (Apriori and FP-growth) were studied. Although the two algorithms give strong association rules, and the results were so near. But FP-Growth algorithm was more efficiency as Apriori algorithm caused problems with minimum support parameter as, in a small system transaction, big minimum support did not work using it. Also, it makes the memory PC faces memory hangs when minimum support was very low. On the other hand, all of this didn't appear with FP-Growth algorithm, and it was faster in dealing data.

Price discount framings on product bundles with shipping surcharges in the Indian market

Purpose – The purpose of this paper is to study how consumers process price frames of product bundles (product plus surcharge) and discount offers to weigh contentious positions between the weighted-additive and the reference-dependent models. Further, some research suggests bundling, while others suggest partitioning to be a more effective pricing strategy. This research evaluated the relative influences of different price frames to examine which model is supported and what are the boundary conditions for price framing. Design/methodology/approach – Two online studies were conducted on Indian adults who had prior experiences of online purchases. They were asked to judge attractiveness of bundles (product along with shipping surcharge). Discounts were shown on the product, the surcharge or on the overall bundle either as partitioned prices or as a bundle. Findings – Across two studies on low- and high-priced products, discounts on shipping surcharge increased attractiveness of the bundle compared to a similar discount on the product or on the overall bundle, supporting the reference-dependent model. Further, for a low-priced product, bundling increased attractiveness, while for a high-priced product, partitioning was more attractive. Research limitations/implications – More research is needed to examine whether these results translate to other kinds of products, surcharges or discount promotions and in different populations. Originality/value – This research makes important contributions to theoretical and practical aspects of bundling and partitioned pricing research. It also adds much needed data about evaluation of product bundles with shipping surcharges among Indian customers.
