Multi-staged R&D projects are copy-book cases of compound real options. Traditional compound option models assume a constant volatility over the lifetime of the project. Building on the n-fold compound option model of Cassimon et al. (2004), we extend this model to allow for phase-specific...

This paper applies the theory of social networks to P2P systems, creating a social-network-based P2P network topology formation algorithm for file sharing. The algorithm extends the Gnutella P2P file sharing technology, which uses super nodes for searching and for relaying shared files between...

Social media offer many opportunities for organizations but present, at the same time, many challenges, too. Particular attention must be paid to the new patterns of behavior emerging in organizations. We argue that these patterns derive both from the technical characteristics of the virtual...

The current access policies and funding schemes of computing e-infrastructures represent a huge challenge for the sustainable growth of computing e-infrastructures and a serious jeopardy for investments made into these e-infrastructures. In order to be able to address these issues, the economics...

Cloud computing, which can be described as a technology for provisioning computing infrastructure as a service, runtime platform as a service, and software as a service, is considered as a keystone for innovation in the IT area. However, a limiting factor to innovation through cloud computing...

Financial analysis software have known a strong development during these last years due to the fact of an evolution of the technical data-processings, but equally of the conflictual relationship between users and publishers. The development to the artificial intelligence transforms traditional...

The Capital Asset Pricing Model (CAPM) is theoretically incomplete in its demandside focus, risk-averse investors, and internally inconsistent homogeneous beliefs; is not conclusively supported empirically; and yet it legitimizes a notion that investors can earn higher returns by bearing...

In this paper we show the advantages of staged investments for venture capitalists. We develop an option-pricing model that enables to evaluate the flexibility acquired by a venture capitalist when he stages his investment process. Instead of investing a fixed amount at the beginning of the...

The main hypothesis examines whether real options logic is applied by entrepreneurs in undertaking key organisational change (e.g. ownership, technology, location, line of business etc.). This is explored in a model of firm performance using data collected in face-to-face interviews with...
