PRODUCT IMPROVEMENT AND TECHNOLOGICAL TYING IN A WINNER‐TAKE‐ALL MARKET*

In a winner‐take‐all duopoly for systems in which firms invest to improve their products, a vertically integrated monopoly supplier of an essential system component may have an incentive to advantage itself by technological tying. If the vertically integrated firm is prevented from technologically tying, there is an equilibrium in which the more efficient firm invests and serves the entire market. However, another equilibrium may exist in which the less efficient firm wins the market. Technological tying enables a vertically integrated firm to foreclose its rival. The welfare implications of technological tying are ambiguous and depend on equilibrium selection.     

TYING IN TWO‐SIDED MARKETS WITH MULTI‐HOMING*

This paper analyzes the effects of tying on market competition and social welfare in two‐sided markets when economic agents can engage in multi‐homing by participating in multiple platforms to reap maximal network benefits. The model shows that tying induces more consumers to multi‐home and makes platform‐specific exclusive content available to more consumers, which is beneficial to content providers. As a result, tying can be welfare‐enhancing if multi‐homing is allowed, even in cases where its welfare impacts are negative in the absence of multi‐homing. The analysis thus can have important implications for recent antitrust cases in industries where multi‐homing is prevalent.     

Ain't it “suite”? Bundling in the PC office software market

Research Summary: We examine the importance of office suites for the evolution of the personal computer (PC) office software market in the 1990s. An estimated discrete‐choice model reveals a positive correlation of consumer values for spreadsheets and wordprocessors, a bonus value for suites, and advantages for Microsoft products. We employ the estimates to simulate various hypothetical market structures to evaluate the profitability, welfare, and competitive effects of suites under alternative correlation assumptions. We find that firms benefit greatly from bundling components (i.e., a spreadsheet and a word processor) when the correlation of consumer preferences over the components in the bundle is positive. Our work adds another aspect to the recent work in the strategy literature that examines benefits from bundling when there are complementary relationships across the products in the bundle. Managerial Summary: Our research helps managers understand the conditions under which product bundling is likely to be most profitable. We show that one key to enhanced profitability is the correlation in consumer preferences over the individual products. We consider the performance implications of bundling under a variety of alternative market structures and competitive environments. Our analysis reveals that firms benefit greatly from bundling when the correlation of consumer valuations over the products is positive. Consumers benefit as well. Hence, bundling is a win‐win for firms and their customers. Since profits increase by more than consumer surplus, bundling leads to increased value capture by the firms. Consequently, it may be profitable for firms to invest in actively increasing the correlation in consumer preferences over products in the bundle.     

Tying in evolving industries,when future entry cannot be deterred

We show that the incentive to engage in exclusionary tying (of two complementary products) may arise even when tying cannot be used as a defensive strategy to protect the incumbent’s dominant position in the primary market. By engaging in tying, an incumbent firm sacrifices current profits but can exclude a more efficient rival from a complementary market by depriving it of the critical scale it needs to be successful. In turn, exclusion in the complementary market allows the incumbent to be in a favorable position when a more efficient rival will enter the primary market, and to appropriate some of the rival’s efficiency rents. The paper also shows that tying is a more profitable exclusionary strategy than pure bundling, and that exclusion is the less likely the higher the proportion of consumers who multi-home.     

Follow the small? Information‐revealing adoption bandwagons when observers expect larger firms to benefit more from adoption

We extend understanding of information‐revealing bandwagons by considering a common condition under which adoption of a practice by small organizations, rather than large ones, has a disproportionate influence on future adoption propensities. We hypothesize that when the value of adoption increases with organizational size, smaller adopters have such disproportionate influence because they allow observers better to infer that adoption will be profitable for their own organization. We elaborate the theory by predicting that alternative information sources moderate the influence of smaller adopters. Empirically, we test our theory with longitudinal data on the adoption of the ISO 9000 quality management standard. Copyright © 2007 John Wiley & Sons, Ltd.     

Non‐additivity in portfolios of exploration activities: a real options‐based analysis of equity alliances in biotechnology

Firms invest in exploration‐oriented activities to seek competitive advantage and in response to changing environments. Real options formulations represent an emerging strand of thinking on such investments. In this paper we begin with the observation that firms often simultaneously invest in multiple exploration projects. We identify two sources of potential interactions among these real options investments. First, we investigate the effects of correlations between the outcomes in different options. Second, we analyze the effects of investments that are fungible across project options. We show that under different conditions multiple options can be sub‐additive (due to redundancies in outcomes) or super‐additive (due to fungible inputs). We test the implications of our model with data from the biotech industry and find supporting evidence. Our model and results have some interesting implications for the exploration literature and real options lens. Copyright © 2004 John Wiley & Sons, Ltd.     

Successive Oligopolies with Differentiated Firms and Endogeneous Entry

We develop a model of successive oligopolies with endogenous entry, allowing for varying degrees of product differentiation and entry costs in both markets. We show that downstream conditions dominate the overall profitability of the two‐tier structure while upstream conditions mainly affect the distribution of profits. We analyze how two‐part tariffs and resale price maintenance shape the endogenous market structure and study their welfare effects. In contrast to previous literature, we find that welfare under linear prices can be larger than under twopart tariffs although the latter avoids double marginalization. This is because linear prices induce more downstream market entry.     

Estimating the Demand for Service Bundles under Three‐Part Tariffs

Consumers may face demand uncertainty when choosing a service plan under three‐part tariffs, and preferences for multiple services may be inter‐dependent. To examine such a demand system, we construct a two‐stage discrete/continuous choice model for service bundles, allowing for interactive utility and preference correlations. Implementing a piecewise maximization approach to consumers’ non‐differentiable utility maximization problem, we estimate the model via simulated method of moments. We empirically illustrate the model using data from a Chinese wireless service provider. Our counterfactual analysis shows that the three‐part tariffs with interchangeable units show no significant loss of revenue, compared to existing tariffs.     

Pass‐Through and the Prediction of Merger Price Effects

We use Monte Carlo experiments to study how pass‐through can improve merger price predictions, focusing on the first order approximation (FOA) proposed in Jaffe and Weyl [ 2013 ]. FOA addresses the functional form misspecification that can exist in standard merger simulations. We find that the predictions of FOA are tightly distributed around the true price effects if pass‐through is precise, but that measurement error in pass‐through diminishes accuracy. As a comparison to FOA, we also study a methodology that uses pass‐through to select among functional forms for use in simulation. This alternative also increases accuracy relative to standard merger simulation and proves more robust to measurement error.     

Managerial decision making and firm performance under a resource‐based paradigm

A framework is presented that connects managerial decision making to resource building and firm performance. The framework takes a behavioral view of decision making and distinguishes two distinct decision‐making processes. First there is the creative conceptualization of new resource configurations that are intended to deliver competitive advantage. Then there is the painstaking development of resources required to implement strategy. We argue that heterogeneity in the resources of rival firms arises from the interplay of these two processes: resource conceptualization and resource development. Heterogeneity spawns performance differences that can be explained ex ante from characteristics of managerial decision‐making processes. We illustrate the approach in a simulated decision‐making environment representing a highly competitive and dynamically complex industry. Results from repeated simulation experiments conducted with executive and MBA students show vast differences in performance among firms, even when they started with identical resource positions. In a departure from traditional resource‐based literature, we explain how these differences stem from path dependent accumulation of resources and spontaneous variety in the way rivals conceptualize resources.

The Role of Hybrid Organizations in Scaling Social Innovations in Bottom‐of‐the‐Pyramid Markets: Insights from Microfinance in India

While social innovations that solve financial exclusion have gained increasing attention as a means of helping the poor in developing markets, little research has empirically investigated the types of organizations that drive these innovations to achieve scale. Hybrids, a type of organization that exist in between traditional organizational forms, are said to have rapidly gained prevalence, especially in bottom‐of‐the‐pyramid markets. Some scholars claim that hybrids are largely responsible for the spread of established social innovations, yet hybrids do not constitute a homogenous group; instead each hybrid form exists on a spectrum between pure for‐profit and not‐for‐profit organizational forms. It is important that empirical research investigates the role that various hybrid forms play in scaling established social innovations, especially under various bottom‐of‐the‐pyramid market conditions. To this end, using two market‐level outcome measures of scale achieved (prevalence and usage), the authors pursue two research objectives: to study (1) the extent to which, alternative hybrid forms (not‐for‐profit, quasi‐profit, and for‐profit hybrids) drive social innovation; and (2) the relative propensity of these hybrid forms to drive social innovation under varying bottom‐of‐the‐pyramid market conditions, specifically varying levels of development and social diversity. By theorizing how different organizational forms act given their degree of hybridity, the authors develop and test six hypotheses using data sets on microfinance organizations in India. Accordingly, they find that (1) compared with not‐for‐profit and for‐profit hybrids, quasi‐profit hybrids have a propensity to become more prevalent and achieve greater usage in bottom‐of‐the‐pyramid markets overall. Yet, within the spectrum of hybrid forms, (2) not‐for‐profit hybrids are more likely to become more prevalent and achieve greater usage in markets with lower development levels, whereas (3) for‐profit hybrids are more likely to become more prevalent and achieve greater usage in markets with lower social diversity when compared with other hybrid forms.     

TWO‐SIDED MARKETS WITH PECUNIARY AND PARTICIPATION EXTERNALITIES*

The existing literature on two‐sided markets addresses participation externalities, but it has neglected pecuniary externalities between platforms. In this paper we build a model that incorporates both externalities. In our set‐up, differentiated platforms compete in advertising levels and offer consumers a service free of charge that is financed through advertising. We show that advertising can exhibit the properties of a strategic substitute or complement. Surprisingly, we find that platform profits can increase with market entry and that there are cases in which the level of advertising rises with entry. We also consider endogenous entry and provide a welfare analysis.     

Status in a strange land? Context‐dependent value of status in cross‐border venture capital

Research Summary: While recent literature has depicted status as an intangible asset that is firm‐specific and mobile, we have a limited understanding of whether status confers advantage in a way similar to other intangible assets. This study examines the macro‐structural contingencies that influence the marginal value of firm status as firms expand to new markets. Building on the literatures on status and social approval assets, as well as globalization and international management, we hypothesize that two conditions influence how valuable home‐country status will be in a given host country: the interconnectedness of the home and host countries, and their relative position in the global network. We test our hypotheses in a study of 187 venture capital (VC)‐backed biotechnology ventures in 19 countries between 1990 and 2006. Managerial Summary: Startups typically prefer high‐status VC investors for endorsements, network connections, and resources. One might expect the benefits of high‐status VCs to be even higher when they invest across borders. Yet, we show that status is ingrained in context, and that the performance advantage of partnering with high‐status cross‐border VC firms depends on the relationship between the country of the VC firm and that of the startup. We find that, when the VC industries in the two countries are more connected, the positive effect of cross‐border VC firm status on successful exit is amplified. However, when the VC firm comes from a more central country than the startup, the benefits of VC firm status are less pronounced and vice versa.     

ORGANIZATIONAL STRUCTURE AND THE DIVERSIFICATION DISCOUNT: EVIDENCE FROM COMMERCIAL BANKING*

We provide evidence on organizational structure and performance at bank holding companies (BHC's). First, we show that a BHC's member banks benefit from access to internal capital markets. Second, we ask if these benefits are best realized within loosely structured, decentralized organizations or more consolidated, centralized firms. We find that BHC's with many subsidiaries are less profitable and have lower q ratios than similar BHC's with fewer subsidiaries. However, because we study multi‐unit firms in a single industry, our results suggest that the diversification discount reported in the corporate finance literature reflects not only industry diversification, but also organizational structure.     

Firm‐Size Wage Gaps along the Formal‐Informal Divide: Theory and Evidence

Observationally equivalent workers are paid higher wages in larger firms. This fact is often called the “firm‐size wage gap” and is regarded as a key empirical puzzle. Using microlevel data from Turkey, we document a new stylized fact: The firm‐size wage gap is more pronounced for informal (unregistered) jobs than for formal (registered) jobs. To explain this fact, we develop a two‐stage wage‐posting game with market imperfections and segmented markets, the solution to which produces wages as a function of firm size in a well‐defined subgame‐perfect equilibrium. The model proposes two explanations. First, taxes on formal employment generate a wedge between formal and informal size wage gaps. Thus, government policy can potentially affect the magnitude of the firm‐size wage gaps. The second explanation features a market‐based framework with strategic interactions. Relative to small firms, large firms typically post higher wages for both formal and informal jobs. A high‐wage formal job attracts a larger pool of applicants than a high‐wage informal job. The larger pool of applicants for the formal job, in turn, allows the firm to somewhat lower the initial wage offer, while this second‐round effect is negligible for informal jobs. As a result, size differentials are lower in formal jobs than informal jobs. We argue that the observed patterns in the use of social connections in job search and heterogeneity in job preferences can be used to justify the validity of this second mechanism.     

Exploring firm characteristics that differentiate leaders from followers in industry merger waves: a competitive dynamics perspective

Research in strategic management has shown that the timing of firm participation in a merger wave matters, as early movers have been shown to outperform later ones. However, while the consequences of the timing of action within a merger wave have been assessed, the causes that drive these timing effects remain unknown. We draw on the competitive dynamics perspective to investigate firm‐level factors that influence the large‐scale strategic behavior of leading or following within industry merger waves. We develop hypotheses based on the competitive dynamics argument that the awareness‐motivation‐capability of firms will influence the timing of competitive action. Consistent with this perspective, we show that a firm's strategic orientation, its structure, and its resource base influence the timing of firm entry in merger waves.

Choosing between Order‐of‐Entry Assumptions in Empirical Entry Models: Evidence from Competition between Burger King and McDonald's Restaurant Outlets

We demonstrate how a non‐nested statistical test developed by Vuong [1989] can be used to assess the suitability of alternate order‐of‐entry assumptions used for identification purposes in empirical entry models. As an example, we estimate an entry model of McDonald's and Burger King restaurant outlets in United States. The data set focuses on relatively small ‘isolated’ markets. For these markets, the non‐nested tests suggest that order‐of‐entry assumptions that give Burger King outlets a first‐mover advantage are statistically preferred. Last, a Monte Carlo experiment provides encouraging results suggesting that the Vuong‐type test yields reliable results within the entry model framework.     

On Stability in Competition: Tying and Horizontal Product Differentiation

We combine Hotelling’s model of product differentiation with tie-in sales. A monopolist in one market competes with another firm in a second market. In equilibrium firms choose zero product differentiation. Due to the tying structure no firm can gain the whole market by a small price reduction. A differentiation effect due to tie-in sales leads to this equilibrium stability.      

Investigating Adoption of Free Beta Applications in a Platform‐Based Business Ecosystem

Planning new product development (NPD) activities is becoming increasingly difficult, as contemporary businesses compete at the level of business ecosystems in addition to the firm‐level product‐market competition. These business ecosystems are built around platforms interlinking suppliers, complementors, distributors, developers, etc. together. The competitiveness of these ecosystems relies on members utilizing the shared platform for their own performance improvement, especially in terms of developing new valuable offerings for end users. Therefore, managing the development of the platform‐based applications and gaining timely end‐user input for NPD are of vital importance both to the ecosystem as a whole and to the developers. Subsequently, to succeed in NPD planning developers utilizing beta testing need a thorough understanding of the adoption dynamics of beta products. Developers need to plan for example resource allocation; development costs; and timing of commercial, end‐product launches. Therefore, the anticipation of the adoption dynamics of beta products emerges as an important antecedent in planning NPD activities when beta testing is used for gaining end‐user input to the NPD process. Consequently, we investigate how free beta software products that are built upon software platforms diffuse among their end users in a cocreation community. We specifically study whether the adoption of these beta products follows Bass or Gompertz model dynamics used in the previous literature when modeling the adoption of stand‐alone products. Further, we also investigate the forecasting abilities of these two models. Our results show that the adoption dynamics of free beta products in a cocreation community follow Gompertz's model rather than the Bass model. Additionally, we find that the Gompertz model performs better than the Bass model in forecasting both short and long out‐of‐sample time periods. We further discuss the managerial and research implications of our study.     

Sufficient Decisions in Multi‐Sided and Multiproduct Markets

We show that in many models where firms make multiple decisions, analysis can be made more tractable by re‐formulating the model into one in which each firm makes a single choice, which we call a sufficient decision. The transformation allows application of standard techniques in these settings, including pass‐through for tax incidence and upward pricing pressure for merger analysis. The transformation works because the assumption of profit maximization links the firms’ decisions together. Examples include models of monopoly and oligopoly in two‐sided markets, where a natural sufficient decision may be the number of transactions that the firm facilitates, and multiproduct markets.
