Information is an important asset of any organisation and the protection of this asset, through information security is equally important. This paper examines the relationship between corporate governance and information security and the fact that top management is responsible for high-quality information security.

In this paper, we consider a dynamic asset pricing model in an approximate fractional economy to address empirical regularities related both investor protection and past information. Our newly developed features not only controlling shareholder who diverts fraction of the output, but also good (or bad) memory his budget dynamics which can be well-calibrated by pathwise way from historical data....

We show that efficient exchange obtains independently of the degree to which a legal system protects the rights of owners. We study a number of different legal rules, including property rules (strong protection), liability rules (any party can take the owner’s asset but must pay a legally-determined compensation), and even rules that protect the owner’s interests very weakly (liability rules wi...

The static asset protection problem (SAP) in a road network is that of allocating resources to protect vertices, given any possible behavior by an adversary determined to attack those assets. The dynamic asset protection (DAP) problem is a version of SAP where the asset is following a fixed and widely known route (e.g., a parade route) and needs to be protected. We formalize what it means for a...

We consider a mean-variance general equilibrium economy where the expected returns for controlling and non-controlling shareholders are different because the former are able to divert a fraction of the profits. We find that when investor protection is poor, asset return correlation affects ownership structure in a positive way. Higher return correlation lowers the benefits of diversification wh...

Virtual Worlds are socio-technical systems, which means that they are IT-systems that are specifically catered to the users. This PhD thesis provides a systematic IT-Security analysis for Virtual Worlds with a client-server architecture and defines security requirements taking into account the different factors for perceived entertainment. IT-Security focuses on the protection of digital assets...
