Open source, dual licensing and software competition

To distribute software, commercial vendors of proprietary software have the opportunity to use some dual licensing (DL) strategy i.e. to provide their software under two different licensing terms (proprietary and open source). We investigate the relevance and impacts of this distribution strategy in the presence of an incumbent open source software competitor. We determine the conditions for this strategy to be profitable for the commercial firm and its impact on price, market shares and welfare. We show that dual licensing may be used as a complement for proprietary software when development spillovers are large. We examine how, in this case, a dual licensing strategy can be used to exclude the open source software from the market and how this is compatible with higher price and lower market share for the proprietary distribution. This situation can also generate conflicts of interests between proprietary software and users resulting in sub-optimal outcomes. Finally, our analysis reveals the key role played by development spillovers and software compatibility for the DL decision.

Towards a Sustainable Tourism

Awareness of the environment and the need to protect it has increased markedly in recent decades, and market actors, consumers and other stakeholders have been progressively more aware of ecological issues. Awareness of the pollution caused by mass tourism has resulted in the emergence of the concept of sustainable tourism which encompasses both environmental and societal concerns. This paper reviews work on sustainable tourism, highlighting the main issues which are illustrated by empirical examples in this new research framework.

Lessons inferred from NFC mobiquitous innovative information service.

In this article, we first overview NFC proof-of-concept and pilot projects which were developed in MBDS innovation group since the inception of the NFC standard in 2004 under partnership and contracts from industry partners and the French Ministry of Industry. We give a generic NFC multi-modal development framework to ease NFC development inspired by our data base know how. We then infer some architectural lessons and introduce a CS research on formal interaction layer to handle mobiquitous systems (ASTRA project). We finally outline an area of Economic research concerning mobiquitous virtual cash along with a discussion on expected business models.

Heterogeneous investors and trading platforms competition

Purpose - – The purpose of this paper is to consider competition’s issues between European market firms, such as Euronext, and multilateral trading facilities, following Markets in Financial Instruments Directive’s enforcement. This new domestic competition is adding to the existing international competition among financial centers. While diversification of local trading services can improve the international competitiveness of a financial center, the fragmentation of order flows can harm its attractiveness. Design/methodology/approach - – The theoretical setting analyzes the interaction between heterogeneous who experiment network externalities, and heterogeneous local trading services providers (alternative platforms and incumbent) in an international context. The authors compare two forms of organizations of the market: a consolidated market, and a fragmented market with alternative platforms – in both cases, in competition with a foreign universe. Findings - – The results of this study point out the importance of the trade-off between diversification and externalities. With alternative platforms entry, enhanced competition decreases fees and redistributes informed investors between the foreign market and the domestic one. The increase of domestic platforms’ number then has more complex effects on externalities (of information and liquidity). When the liquidity externalities are low, the diversification of financial platforms increases the number of investors on domestic centers. When liquidity externalities are not negligible, despite the decrease of fees, this same diversification orientates more informed investors to the foreign center. Originality/value - – This model is the first to analyze jointly the internal and international competition of trading platforms with heterogeneous investors.

Publisher's Announcements and Piracy-Monitoring Devices in Software Adoption

In this paper, we investigate the distribution strategy of a software publisher. The user adoption context is characterized by uncertainty about quality (experience good) and heterogeneous piracy costs. Users can purchase or get unauthorized/illegal copies (digital piracy) of the software during two periods (or not adopt at all). Between these two periods, users can acquire information through word-of-mouth. To maximize profit, the publisher needs to decide about price, quality and level of monitoring of piracy. We show that the software publisher can profit from accommodation a certain level of piracy of the product. We add to the literature by explicitly considering the opportunity for the publisher to cheat about future price and monitoring levels (misleading announcements). This strategy that is falsely permissive towards piracy, can sometimes appear more profitable. However, when the degree of sophistication of user expectations about the publishers strategy increases, only a strategy that is permissive (with respect to piracy) with non misleading announcements remains robust.

Mihail Manoilescu's International Trade Theories in Retrospect: How and When Emerging Economies Must Be Protected?

Mihail Manoilescu was one of the main intellectual personalities of the interwar period in Romania. He was known as a politician and a central banker, but also as an economist. From the very beginning of his theoretical and practical career, or at least from the late 1920s till the end of his life, Manoilescu’s ideas and theories were marked by a clear continuity and consistency based on the theory of protectionism. His defence of protectionism is generally presented as clumsy and founded on incorrect method. This paper contributes to a testament of Manoilescu’s conclusions, the validity of which we test in two different paradigms. Section 2 presents the theory of protectionism formulated by the author. Section 3 tries to interpret Manoilescu’s views in modern terms. It presents arguments assimilating his analysis to some post-Marxist presentations of the after-war period. It also develops a Ricardian model proving that Manoilescu’s intuitions can be verified in a Ricardian context. The last section concludes.
