We examine whether competing firms in a Hotelling model should increase the scope of their targeting from advertising spending or price alone to both and targeting.

This paper develops a new rationale for decentralization in distribution channels: providing one-stop comparison shopping experience consumers. In our duopoly model, when consumers are knowledgeable about their brand preferences, each manufacturer would distribute through its own vertically integrated retail outlets only. When some unsure however, it may be optimal one of the manufacturers to also competitor’s outlets. The resulting equilibrium has several interesting properties. First, only...

This research introduces a new heuristic decision model called myopic-value of perfect information (VPI) to study multiarmed bandit (MAB) problems. The myopic-VPI approach only involves ranking the alternatives and computing one-dimensional integration obtain expected future value exploration. Because is intuitive does not involve solving dynamic programming problem, it has potential serve as useful exploration-exploitation tradeoffs. We conduct series simulation experiments its performance...

Consumers in high-stakes product markets such as healthcare or finance often rely on experts' recommendations before making a purchase decision. However, how an expert constructs specific set of and it subsequently affects consumer choices outcomes have been understudied. We propose empirical framework that econometrically recovers combines them with heterogeneous consumers' choice products services. then apply the to examine kidney disease patients' dialysis facilities. Using detailed data...

In this research, we introduce a new heuristic decision model called Myopic-VPI to study Multi-armed bandit (MAB) problems in marketing and business. The approach only involves ranking the alternatives computing one-dimensional integration obtain expected future value of exploration. Because is intuitive does not involve solving dynamic programming problem, it has potential serve as useful exploration-exploitation trade-offs. We conduct series simulation experiments its performance relative...

In this paper, we contribute to the literature on structural modeling of online consumer search by (i) separately identifying product position and social influence effects, (ii) allowing consumers purchase multiple items in each session. We achieve these two goals utilizing a publicly available dataset from field experiment conducted an music platform new model that allows purchases The experiment, which manipulates presentation formats, positions, popularity information, provides us with...

In this paper we study the non-holomorphic strict endoscopic parts of inner cohomology spaces a modular Siegel threefold respect to local systems. First show that there is non-zero subspace part such it constructed by global theta lift automorphic froms $(GL(2)\times GL(2))/G_{m}$. Secondly, present an explicit analytic calculation levels lifted forms into GSp(4), based on paramodular representations theory for $GSp(4; F)$. Finally, prove conjecture, C. Faber and G. van der Geer, gives...
