    Abstract: As IT technology advanced, a new style of innovation emerged, in which a leading innovation company invites end-users to its open software service platform. With respect to this type of innovation, a lot of innovation studies were performed to understand the structure of the interaction among users and the platform provider from the perspective of network science. By concentrating only on the internal mechanisms among agents, the previous studies miss to consider innovation through collective intelligence. A platform provider plays an important role in the innovation. In this research, we investigate the structure of a service network with empirical data gathered from AppExchange and discuss the role of a platform provider in innovation through collective intelligence. Our results suggest that the platform provider led the innovation in the initial period and, then, third party developers became gradually innovation leaders. Our findings are expected to re-orient the research focus from internal mechanisms to the role of platform providers.

    Abstract: Social networks can be differentiated according to the type of entities (i.e., humans or objects) that are represented within them. These networks can be called human networks and social object networks, respectively. Actors in human networks can act strategically to maximize their own payoffs during interactions with other humans. However, actors in social object network (e.g., SaaS service network) are not able to perceive the environment and act strategically upon that at any time. Only when they join the network, humans position them such that it maximizes their payoff. This paper contends that existing network formation models lack sufficient attention to social object networks (e.g., SaaS service networks). Therefore, we propose a new network formation model, through which we are able to explain how a SaaS service network emerges during the service composition procedure by service developers. The new network formulation model not only considers the usage frequency and reputation but also the similarity of the functionalities of the main SaaS services. It also explains how social objects (e.g., SaaS services) can benefit from establishment of links among each other in the network.
    Keywords: Software-as-a-Service Network, Network Formation Model, Social Object Networks.

    Abstract: The financial crisis has led to a widespread loss of trust in financial intermediaries of all kinds, perhaps helping to open the way towards the general acceptance of alternative technologies. This paper briefly summarises the crypto-currency phenomenon, separating the ‘currency’ issues from the potential technology benefits. With respect to crypto currencies, the paper argues that these can’t undermine the ability of central banks to conduct monetary policy. They do, however, raise consumer protection and bank secrecy issues. The valuation of Bitcoins and price volatility issues are discussed, as well as electronic theft, contract failures, etc., all of which could result in large losses to users and hence ultimate costs to the taxpayer (e.g. the failure to provide adequate private pensions resulting in increased reliance on public pensions). The anonymity features of the crypto-currencies also facilitate tax evasion and money laundering, both of which are major public policy concerns. The technology associated with crypto-currencies, on the other hand, could ultimately shift the entire basis of trust involved in any financial transaction. It is an innovation that creates the ability to carry out transactions without the need for a trusted third party; i.e. a move towards trust-less transactions. This mechanism could work to eliminate the role of many intermediaries, thereby reducing transactions costs by introducing much needed competition to incumbent firms. The generic issues that policy makers need to examine are summarised.

    Abstract: The aim of using information technology and information systems is to improve the efficiency and effectiveness of economic activities. Examined by their size categories, the enterprises operating in the Visegrád group of countries produce different average added value, which can also be detected in their use of IT infrastructure. In comparison to their Visegrád peers, micro-enterprises in Slovakia, small-sized businesses in Poland, medium-sized enterprises in the Czech Republic and corporations in Hungary produced the highest added value on average, which is closely related to the usage of IT infrastructure in those countries. It also follows that various business information systems can be found at the small- and mediumsized enterprises in the Czech Republic and Poland in the largest proportion. These systems were applied by Hungarian and Slovakian small- and medium-sized enterprises at the lowest frequency rate. Personnel responsible for the operation of IT functions at micro- and smallsized enterprises vary from country to country, an employee working at a lower position was entrusted with this task in the Czech Republic and Slovakia, while IT managers in Hungary and external specialists in Poland were in charge of the operation of IT infrastructure. Corporations tended to entrust IT managers with this task in each of the studied countries. --
