Optimal Front Page Advertising
We consider a model of an on-line software market, where an intermediary distributes products from sellers to buyers. When products of sellers are vertically differentiated, an intermediary, earning a proportion of sales, has an incentive to hide the worse product on the second page, and only keep the better product on the front page: that weakens the competition, allowing the seller with the better product to charge a higher price. With heterogeneous visiting costs to the second page, the platform's revenue might improve, but the outcome will become socially suboptimal.
Abstract. Background: Digital content is a key part of a Digital University, which is becoming more relevant to meet the requirements of the digital world. Traditional universities should in fact “reinvent themselves”: they need to switch quickly from the usual focus on managing the learning process (program portfolio) to managing the educatinal experience of the target audience, whose expectations of the personalized, adaptive and 24/7 format of interaction with the learning system become more natural. Design/Methodology: Transformation affects organiza-tion, processes, people, including educational content and the ways to present it. The paper reviews the key aspects of a digital university with the main focus on digital educational content and explores different perspectives of the digital content. Objective: This paper outlines the generalized model of the digital education and suggests the application of a digital platform for the innovative educational purposes by the example of the idea of the digital “SuperBook” press. Results: The authors of the paper propose the concept of an innovative SuperBook web-service, which can be used on the basis of a digital university and can provide great opportunities to students to use digital content. Conclusion: The research gives a better insight in transformation process of the educational content. This research can be used as a basis for further transformation to a digital university. An analysis of the current trends of the digital university and the research of the interested parties showed that the SuperBook technology platform will be in demand in the academic field.
Platforms as key players in multi-sided markets do not turn out to be the latest phenomenon in the economy. However, rapid development of digital technologies and widespread Internet access have raised a question on the need to determine their subject area, as well as the effects of their emergence and functioning. Platforms emerge in multi-sided markets, they link two or more groups of users, build their business models on network effects, and use non-neutral price structure to attract more users on both sided. Platform can connect different groups of users whose interaction with one another raises positive (consumers, producers, government) and negative (advertisers and platform users) indirect network effects. At the same time, connecting advertisers to the platform may, on the one hand, be associated with the fact that advertisers may assume that the viewers of the advertisement will make a purchase one day. On the other hand, viewers of the advertisement can watch it due to the Arrow information paradox. This paper while determining the characteristics of players in multi-sided markets proposes an approach to analyzing their coordination and distribution effects. The variance in the estimates of these effects may be associated with a disparity of distributional effects valuations, and, apart from this, it may be bounded to the interval of the study. These estimates are important in the light of a widespread debate in the academic and decision-making community on the need of changes in competition law enforcement regarding regulation of platforms.
Today we see the great interest to the field of Software Ecosystems that have been related to products, community of developers around a product and gives the certain advantages to the platform owners and participants of the ecosystem. Mobile healthcare ecosystems – is a new trend, especially in Russia. Nonetheless many big companies see great potential in building the interface between healthcare and the mobile industry. The paper provides a step towards better understanding of background, examples and opportunities for further development of mobile healthcare ecosystems in Russia and all over the world.
The paper examines the structure, governance, and balance sheets of state-controlled banks in Russia, which accounted for over 55 percent of the total assets in the country's banking system in early 2012. The author offers a credible estimate of the size of the country's state banking sector by including banks that are indirectly owned by public organizations. Contrary to some predictions based on the theoretical literature on economic transition, he explains the relatively high profitability and efficiency of Russian state-controlled banks by pointing to their competitive position in such functions as acquisition and disposal of assets on behalf of the government. Also suggested in the paper is a different way of looking at market concentration in Russia (by consolidating the market shares of core state-controlled banks), which produces a picture of a more concentrated market than officially reported. Lastly, one of the author's interesting conclusions is that China provides a better benchmark than the formerly centrally planned economies of Central and Eastern Europe by which to assess the viability of state ownership of banks in Russia and to evaluate the country's banking sector.
The paper examines the principles for the supervision of financial conglomerates proposed by BCBS in the consultative document published in December 2011. Moreover, the article proposes a number of suggestions worked out by the authors within the HSE research team.
