Dynamic mixed duopoly: A model motivated by Linux vs. Windows
This paper analyzes a dynamic mixed duopoly in which a profit-maximizing competitor interacts with a competitor that prices at zero (or marginal cost), with the cumulation of output affecting their relative positions over time. The modeling effort is motivated by interactions between Linux, an open-source operating system, and Microsoft's Windows in the computer server segment, and consequently emphasizes demand-side learning effects that generate dynamic scale economies (or network externalities). Analytical characterizations of the equilibrium under such conditions are offered, and some comparative static and welfare effects are examined.open-source software; network effects; microsoft; linux; competitive dynamics; strategy;
Globalization and Trust: Theory and Evidence from Cooperatives
We study the effect of globalization on the stock of trust in organizations. We present a simple model of endogenous trust and show that contrary to centralized hierarchies (pure limited liability firms), decentralized organizational structures (cooperatives) foster the emergence of trust. We treat organizations as directly observable ‘summary statistics’ for underlying trust and ask what will be the fate of trust as the world becomes increasingly globalized. Because the cooperative is an intrinsically less efficient organizational form and globalization implies harsher competitive pressures, conventional wisdom suggests that the viability of cooperatives is in jeopardy. We show that this is not necessarily true. If the increase in competition is bundled with an increase in uncertainty and risk, the cooperative may become a more efficient organizational form. We conclude that globalization does not necessarily erode trust. The case of Mondragón Corporación Cooperativa is used to motivate assumptions and illustrate the results.http://deepblue.lib.umich.edu/bitstream/2027.42/39978/3/wp592.pd

Competing through business models
In this article a business model is defined as the firm choices on policies, assets and governance structure of those policies and assets, together with their consequences, be them flexible or rigid. We also provide a way to represent such business models to highlight the dynamic loops and to facilitate understanding interaction with other business models. Furthermore, we develop some tests to evaluate the goodness of a business model both in isolation as well as in interaction with other business models of different organizations, be those competitors, complements, suppliers, partners, etc.Business model; Interaction; Competitive Strategy; Competitive Dynamics;

Investment Incentives in Open-Source and Proprietary Two-Sided Platforms
We study incentives to invest in platform quality in open-source and proprietary two-sided platforms. Open platforms have open access, and developers invest to improve the platform. Proprietary platforms have closed access, and investment is done by the platform owner. We present five main results. First, open platforms may benefit from limited developer access. Second, an open platform may lead to higher investment than a proprietary platform. Third, opening one side of a proprietary platform may lower incentives to invest in platform quality. Fourth, the structure of access prices of the proprietary platform depends on (i) how changes in the number of developers affect the incentives to invest in the open platform, and (ii) how investment in the open platform affects the revenues of the proprietary platform. Finally, a proprietary platform may benefit from higher investment in the open platform. This result helps explain why the owner of a proprietary platform such as Microsoft has chosen to contribute to the development of Linux

Business Model Innovation and Competitive Imitation: The Case of Sponsor-Based Business Models
This paper provides the first formal model of business model innovation. Our analysis focuses on sponsor-based business model innovations where a firm monetizes its product through sponsors rather than setting prices to its customer base. We analyze strategic interactions between an innovative entrant and an incumbent where the incumbent may imitate the entrant's business model innovation once it is revealed. The results suggest that an entrant needs to strategically choose whether to reveal its innovation by competing through the new business model or conceal it by adopting a traditional business model. We also show that the value of business model innovation may be so substantial that an incumbent may prefer to compete in a duopoly rather than to remain a monopolist

When Does a Platform Create Value by Limiting Choice?
We present a theory for why it might be rational for a platform to limit the number of applications available on it. Our model is based on the observation that even if users prefer application variety, applications often also exhibit direct network effects. When there are direct network effects, users prefer to consume the same applications to benefit from consumption complementarities. We show that the combination of preference for variety and consumption complementarities gives rise to (i) a commons problem (to better satisfy their individual preference for variety, users have an incentive to consume more applications than the number that maximizes joint utility); (ii) an equilibrium selection problem (consumption complementarities often lead to multiple equilibria, which result in different utility levels for the users); and (iii) a coordination problem (lacking perfect foresight, it is unlikely that users will end up buying the same set of applications). The analysis shows that the platform can resolve these problems and create value by limiting the number of applications available. By limiting choice, the platform may create new equilibria (including the allocation that maximizes users' utility); eliminate equilibria that give lower utility to the users; and reduce the severity of the coordination problem faced by users
Platform competition, compatibility, and social efficiency
Katz and Shapiro (1985) study systems compatibility in settings with one-sided platforms and direct network externalities. We consider systems compatibility in settings with two-sided platforms and indirect network externalities to develop an explanation why markets with two-sided platforms are often characterized by incompatibility with one dominant player who may subsidize access to one side of the market. We find that incompatibility gives rise to asymmetric equilibria with a dominant platform that earns more than under compatibility. We also find that incompatibility generates larger total welfare than compatibility when horizontal differences between platforms are small.network; industries; platforms; markets;
Strategy vs. business models vs. tactics
The notion of business model has been used by strategy scholars to refer to "the logic of the firm, the way it operates and how it creates value for its stakeholders." On the surface, this notion appears to be similar to that of strategy. We present a conceptual framework to separate business model from strategy. Business model, we argue, is a reflection of the firm's realized strategy. We find that in simple competitive situations there is a one-to-one mapping between strategy and business model, which makes it difficult to separate the two notions. We show that the concepts of strategy and business model differ markedly when there are important contingencies upon which a well-designed strategy must be based. Our framework also delivers a clear separation between tactics and strategy. This distinction is possible because strategy and business model are different constructs.Business model; Strategy; Competitive dynamics; Interaction;

Bandwidth allocation in peer-to-peer file sharing networks
We present a model of bandwidth allocation in a stylized peer-to-peer file sharing network with s peers (sharers) who share files and download from each other and f peers (freeriders) who download from sharers but do not contribute files. Assuming that upload bandwidth is scarcer than download bandwidth and efficient allocation, we compute the expected bandwidth obtained by each peer. We show that (i) while the exact formula is complex, s/(s + f) is a good approximation and (ii) sharers (freeriders) obtain bandwidth larger (smaller) than s/(s + f). The paper constitutes a first step towards a general analytical foundation for scarce resource allocation in peer-to-peer file sharing networks
