The Role of the Mangement Sciences in Research on Personalization

We present a review of research studies that deal with personalization. We synthesize current knowledge about these areas, and identify issues that we envision will be of interest to researchers working in the management sciences. We take an interdisciplinary approach that spans the areas of economics, marketing, information technology, and operations. We present an overarching framework for personalization that allows us to identify key players in the personalization process, as well as, the key stages of personalization. The framework enables us to examine the strategic role of personalization in the interactions between a firm and other key players in the firm's value system. We review extant literature in the strategic behavior of firms, and discuss opportunities for analytical and empirical research in this regard. Next, we examine how a firm can learn a customer's preferences, which is one of the key components of the personalization process. We use a utility-based approach to formalize such preference functions, and to understand how these preference functions could be learnt based on a customer's interactions with a firm. We identify well-established techniques in management sciences that can be gainfully employed in future research on personalization.CRM, Persoanlization, Marketing, e-commerce,

Dynamic Price Discrimination and Quality Provision Based on Purchase History

This paper develops a general two-period model of product line pricing with customer recognition. Specifically, we consider a monopolist who can sell vertically differentiated products over two periods to heterogeneous consumers. Each consumer demands one unit of the product in each period. In the second period, the monopolist can condition the price-quality offers on the observed purchasing behavior in the first period. In this setup, the monopolist can price discriminate consumers not only by quality, but also by purchase history. Several interesting results are derived. First, we fully characterize the monopolist's optimal pricing strategy when there are two types of consumers, and a simple condition is given to determine whether the monopolist will price discriminate by quality in the first period. We compare it to the case when there is no customer recognition or the firm is able to commit to its future actions. When the type space is a continuum, we show that there is no fully separating equilibrium, and some properties of the optimal contracts (price-quality pairs) are characterized within the class of partitional PBE.Price discrimination; Supermodularity; Submodularity; Behavior-Based Pricing; Ratchet Effect; Bunching

Price differentiation strategies

Both practitioners and academics agree about the importance of price and its direct influenceon consumers’ purchase decision as well as the company profit. In the reality, we rarely see a single price for a given product. One visit in a store already shows that consumers face many various prices. This strategy of differential prices allows to increase profit but also improves consumers’ situation and increases welfare. A wide range of various price differentiation mechanisms exists on the market which makes price differentiation a very interesting phenomenon. Additionally, market developments constantly allow for new price differentiation applications. In this work, I research a fascinating topic of price differentiation, its various forms and new application possibilities in changing market areas

Digital piracy : theory

This article reviews recent theoretical contributions on digital piracy. It starts by elaborating on the reasons for intellectual property protection, by reporting a few facts about copyright protection, and by examining reasons to become a digital pirate. Next, it provides an exploration of the consequences of digital piracy, using a base model and several extensions (with consumer sampling, network effects, and indirect appropriation). A closer look at market-structure implications of end-user piracy is then taken. After a brief review of commercial piracy, additional legal and private responses to end-user piracy are considered. Finally, a quick look at emerging new business models is taken.information good, piracy, copyright, IP protection, internet, peer-to-peer, software, music

ESSAYS ON DYNAMIC PRICING AND BUNDLING IN SUBSCRIPTION MARKETS

This dissertation consists of two essays that investigate dynamic pricing and bundling strategies in subscription markets. In the first essay, we analyze the dynamic price discrimination strategies of a monopolist offering new services on a subscription basis. In subscription markets, the pricing policy can be based on customers’ past purchase behavior (behavioral price discrimination) and time of purchase (intertemporal price discrimination). In the presence of uncertainty regarding the value of new features and heterogeneity in consumer valuations of the existing features, we investigate the profits and rate of adoption of new technology that can be achieved with each pricing strategy. When the prior heterogeneity in consumer valuation of the existing features is relatively large, the monopolist can improve his profits by committing to ignore consumer past behavior and varying prices based only on time. We also study the role of commitment power of the monopolist to announce future prices and correlation in valuations of the new and existing features. In the second essay, we investigate the multi-product pricing strategies of a sequentially innovating monopolist introducing new services. The new service can either represent a new functionality not directly related to the existing service or an enhancement to the existing services. When the existing service is offered in multiple versions, the monopolist can sell the new service separately or bundle the new service with some or all versions of the primary service. We analyze two pricing strategies that represent the two extremes of a spectrum of bundling strategies that a monopolist offering such services can practice: Discriminative Bundling (DB) and Independent Pricing (IP). Using the discriminative bundling (DB) strategy, a service provider offering multiple versions of the primary service bundles the new service only with higher versions of the primary service while selling it separately to remaining customers. Using the independent pricing strategy (IP), the service provider offers the new service separately to all consumers including those buying lower and higher end versions. We find that the comparison of the two strategies in terms of profits depends on the nature of the new service and the general distribution of consumer valuations for the new and the primary services

Modeling Customer Behavior for Revenue Management

In this thesis, we model and analyze the impact of two behavioral aspects of customer decision making upon the revenue maximization problem of a monopolist firm. First, we study the revenue maximization problem of a monopolist firm selling a homogeneous good to a market of risk-averse, strategic customers. Using a discrete (but arbitrary) valuation distribution, we show how the dynamic pricing problem with strategic customers can be formulated as a mechanism design problem, thereby making it more amenable to analysis. We characterize the optimal solution, and solve the problem for several special cases. We perform asymptotic analysis for the low risk-aversion case and show that it is asymptotically optimal to offer at most two products. Second, we consider a revenue-maximizing monopolist firm that serves a market of customers that are heterogeneous with respect to their valuations and desire for a quality attribute. Instead of optimizing the net utility that results from an appropriate combination of product price and quality, as in the traditional model of customer behavior, we consider a setting where customers purchase the cheapest product subject to its quality exceeding a customer specific quality threshold. We call such preferences threshold preferences. We solve the firm’s product design problem in this setting, and contrast with the traditional model of customer choice behavior. We consider several scenarios where such preferences might arise, and identify the optimal solution in each case. In addition to these product design problems, we study the problem of identifying the optimal putting strategy for a golfer. We develop a model of golfer putting skill, and combine it with a putt trajectory and holeout model to identify a golfer’s optimal putting strategy. The problem of identifying the optimal putting strategy is shown to be equivalent to a two-dimensional stochastic shortest path problem, with continuous state and control space, and solved using approximate dynamic programming. We calibrate the golfer model to professional and amateur player data, and use the calibrated model to answer several interesting questions, e.g., how does green reading ability affect golfer performance, how do professional and amateur golfers differ in their strategy, how do uphill and downhill putts compare in difficulty, etc
