The “When” and “Where” Dimensions of Cherry Picking
نویسندگان
چکیده
Due to the use of promotional pricing by supermarkets, there is considerable price variation across weeks within a store and across stores within a week. Consumers may therefore save on their groceries by (1) cherry picking over time (“when”) and (2) cherry picking across stores (“where”). The research focuses on three substantive research questions associated with cherry picking: (1) What variables explain the segmentation by consumer cherry picking patterns on the “when” and “where” dimensions? (2) How much do the different segments save by cherry picking? (3) How do cherry picking patterns affect store performance? A unique data collection approach that allows us to have access to both observational and survey data on a set of households enables us to demonstrate that findings from survey based research are comparable to findings from objective behavioral data.

متن کاملOn the existence of a cherry-picking sequence
Recently, the minimum number of reticulation events that is required to simultaneously embed a collection P of rooted binary phylogenetic trees into a so-called temporal network has been characterized in terms of cherry-picking sequences. Such a sequence is a particular ordering on the leaves of the trees in P. However, it is well-known that not all collections of phylogenetic trees have a cher...

متن کاملDeciding the existence of a cherry-picking sequence is hard on two trees
Here we show that deciding whether two rooted binary phylogenetic trees on the same set of taxa permit a cherry-picking sequence, a special type of elimination order on the taxa, is NP-complete. This improves on an earlier result which proved hardness for eight or more trees. Via a known equivalence between cherry-picking sequences and temporal phylogenetic networks, our result proves that it i...
متن کاملCherry-picking in Labor Markets with Imperfect Information
We study a competitive labor market with imperfect information. In our basic model, the labor market consists of heterogeneous workers and ex ante identical firms who have imperfect information about workers’ productivities. Firms compete by posting wages each round to win the right to make job offers, and take turns to cherry-pick more productive workers. We also consider extensions of the mod...
