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

One-Way Essential Complements

While competition between firms producing substitutes is well understood, less is known about rivalry between complementors. We study the interaction between firms in markets with one-way essential complements. One good is essential to the use of the other but not vice versa, as arises with an operating system and applications. Our interest is in the division of surplus between the two goods and the related incentive for firms to create complements to an essential good. Formally, we study a two-good model where consumers value A alone, but can only enjoy B if they also purchase A. When one firm sells A and another sells B, the firm that sells B earns a majority of the value it creates. However, if the A firm were to buy the B firm, it would optimally charge zero for B, provided marginal costs are zero and the average value of B is small relative to A. Hence, absent strong antitrust or intellectual property protections, the A firm can leverage its monopoly into B costlessly by producing a competing version of B and giving it away. For example, Microsoft provided Internet Explorer as a free substitute for Netscape; in our model, this maximizes Microsoft’s joint monopoly profits. Furthermore, Microsoft has no incentive to raise prices, even if all browser competition exits. This may seem surprising since it runs counter to the traditional gains from price discrimination and versioning. We also show that a essential monopolist has no incentive to degrade rival complementary products, which suggests that a monopoly internet service provider will offer net neutrality. There are other means for the essential A monopolist to capture surplus from B. We consider the incentive to add a surcharge (or subsidy) to the price of B, or to act as a Stackelberg leader. We find a small gain from pricing first, but much greater profits from adding a surcharge to the price of B. The potential for A to capture B’s surplus highlights the challenges facing a firm whose product depends on an essential good

Delayed Multiattribute Product Differentiation

We develop a two-stage model for versioning products with respect to both vertical and horizontal attributes. At first, a firm positions its top-quality “flagship” product in a market with an imperfectly known distribution of tastes and reservation prices. In the second stage, the firm learns these consumer characteristics and has the option of extending its product line by versioning the flagship product using pure horizontal differentiation, quality degrading, or both. The firm's nonconvex versioning problem is solved analytically for the two-product case. We find that ex ante extending the product line through vertical differentiation is optimal for low marginal cost of quality (development cost); otherwise pure horizontal differentiation is superior. Given quasilinear consumer preferences and a uniform distribution of consumer characteristics, versioning with respect to both horizontal and vertical attributes is never optimal. Under delayed differentiation the optimal policy is contingent on the observed demand realization and may lead to horizontal cannibalization and price dispersion for equal-quality products. The firm tends to increase its investment in product quality unless it adopts a state-contingent policy of horizontal versioning for high and vertical versioning for low demand realizations. Following a state-contingent policy, the optimal upfront development effort may be significantly lower than under full ex-ante commitment. The option value of delayed differentiation is generally nonmonotonic in the firm's development cost

The Roles of Corporate IT Infastructure and their Impact on IS Effectiveness

In the strategic alignment model of Henderson and Venkatraman (1993) [1] IT infrastructure has an important but only implicitly defined role. According to evolving literature, IT infrastructure serves many different purposes in large companies. We outline the main missions (roles) of the corporate-wide IT infrastructure and its contribution to IS effectiveness and study the relationship of IT infrastructure with alignment processes and strategic integration. Our empirical tests with data from almost one hundred large companies resulted in three IT infrastructure roles, which reflect the IS communality, strategic, and flexibility dimensions of the corporate-wide IT infrastructure. The roles were not symmetrically related to the IS effectiveness and alignment perspectives. IT infrastructure roles had a significant interplay with strategic integration in improving IS effectiveness. However, the interplay of IT infrastructure roles with alignment perspectives had only marginal effects. Implications of the results for research and practice are discussed

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

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

The Endogenous Value of Information”

This doctoral thesis examines the value of information in settings, where two or more agents interact. In such situations, contrary to one-person decision problems, a more informative signal is not necessarily more valuable, and it may be profit-maximizing for an information seller to deliberately garble or damage his signal before selling it to another agent. More generally, the value of information depends on the precise contractual arrangement under which the information is to be transferred and used. I examine the following applications: (i) value of information in portfolio decision problems; and (ii) the transfer of information to a wealth-constrained investor. In a multiagent setting I examine (iii) the value of hared information services; and (iv) the value of information and flexibility for screening a heterogeneous consumer base

Is Online Product Information Availability Driven by Quality or Differentiation?

We present a game theoretic model for the availability of product information in Internet markets, where buyers can search for multiple products in parallel. We use a multiple-circle variation of Salop’s “unit circle” model of product differentiation where vendors are able to differentiate their products both horizontally (taste) and vertically (quality). We explore the conditions under which vendors make horizontal and vertical product information available to potential customers in equilibrium. We demonstrate that vendors will choose not to provide their full horizontal product information, and will rather leave the buyers with some probabilistic knowledge about their exact horizontal product locations. However, the vendors will release enough horizontal product information for their products to appear distinct from those of competitors. The sellers’ incentives to disseminate vertical product information are shown to be fundamentally different: only the worst possible quality vendors will withhold information on vertical product parameters. Our results suggest an answer for the question that is the title of this paper: Is it the case that online vendors release product information primarily to advertise their product’s superiority or to make clear that their products do not have close competing substitutes? We find that for high quality products the former is more important while the latter gains significance for lower quality products. We present empirical observations of nearly 2,000 products in the PC game industry that provide evidence in favor of the model’s predictions
