This work proposes LEASE, a novel Mobile-P2P lease-based economic incentive model, in which data requestors need to pay the price (in virtual currency) of their requested data items to data-providers. In LEASE, dataproviding mobile peers lease data items to free-riders, who do not have any data items to provide, in lieu of a lease payment. Thus, LEASE not only combats free-riding, but also enti...

The rapid development and diffusion of the information and communications technology (ICT) is the major driving force of the New Economy. While there is ample evidence to suggest that the ICT industry has contributed a great deal to the overall economic growth of the developed countries, its role in the developing countries is far from clear. The pressure of unemployment that may result from IC...

This paper examines the financial sector preconditions for the successful development of a high technology sector. It argues that there is a close relation between types of activities undertaken in different countries and their institutional structures. A distinguishing characteristic of the financing of high technology firms is their evolving pattern of control by different investor groups. Wh...

Unter dem neuen Trend " Sharing Economy " oder auch " Shareconomy " ist ein gemeinschaftlicher Konsum nach dem Motto " Nutzen statt Besitzen " zu verstehen. Diese Bewegung wird insbesondere durch Online-Plattformen unterstützt und teilweise auch dadurch erst ermöglicht. Der folgende Beitrag analysiert Web-Angebote im Bereich Tauschen, Schenken, Leihen und Teilen anhand eines vorher beschriebene...

Although ASP (Application Service Provider) has the potential to fundamentally change the manner in which IT services are provided for user firms, current ASPs often fail to provide good results in accumulating and retaining customers. To fill the gap between the expected benefits of application service and its disappointing results in the real world, we present a conceptual model including thr...

Twenty four patients with severe brain injury who had disturbed behaviours preventing rehabilitation or care in ordinary settings were treated in a token economy. This long-term follow-up study indicates that post-traumatic behaviour disorders can be lastingly improved, and that lengthy rehabilitation can have surprisingly good effects.

A generalized measure of market power is derived that accounts for both supply expansion by the competitive fringe and multi-market participation by the dominant firm. Traditional market power measures are shown to be biased-upward (downward) in the case of complements (substitutes). Numerical simulations suggest that this bias can be pronounced. These findings have potentially important implic...

This paper explores the story behind a crowdfunding service as an example of sharing technology. Research in a small neighborhood of London showed how locally-developed initiatives can differ in tone, scale, ambition and practice to those getting attention in the so-called sharing economy. In local accounts, we see an emphasis on organizing together to create shared spaces for collaborative use...

We investigate the effects of mobile-sourced ridesharing via platforms like Uber, Lyft, and Didi Chuxing on the use of public transit systems. Our study uses trip-level data about Uber usage in New York City, turnstile data about subway usage, and trip-level data about taxicab and shared bike usage. We find that on the surface, ridesharing and subway usage are positively correlated. Exploiting ...

We propose a general model of monopolistic competition, which encompasses existing models while being flexible enough to take into account new demand and competition features. The basic tool we use to study the market outcome is the elasticity of substitution at a symmetric consumption pattern, which depends on both the per capita consumption and the total mass of varieties. We impose intuitive...
