Decomposing Industry Leverage: the Special Cases of Real Estate Investment Trusts and Technology & Hardware Companies
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Different industries exhibit significantly different leverage – companies in the REIT and technology/hardware sectors are extreme examples. The leverage ratio is twice as high with 50% for REITs as for non-real estate firms with around 25% in the U.S.; whereas the technology/hardware sector has the lowest ratio with around 17%. We theoretically and empirically analyse their differences. By decomposing the difference into three channels, we find that the industry-specific channel explains around 67% for REITs and 68% for technology/hardware firms; the value-based channel is mostly responsible for the remaining part. When taking non-linear influences of extreme values into account, the relevance of the industry-specific channel is considerably reduced.

Konferensbidrag (refereegranskat)abstract
- In this paper we present research results from the multi-disciplinary EU research project USEMP (USEMP is a project funded from EU research framework, additional information about project scope and deliverables are available at project’s public website at: http://www.usemp-project.eu/). In particular, we look at the legal aspects of personal data licensing and profile transparency, the development of a personal data value model in Online Social Networks (OSNs) and the development of disclosure scoring and personal data value frameworks. In the first part of the paper we show how personal data usage licensing and profile transparency for OSN activities provides for Data Protection by Design (DPbD). We also present an overview of the existing personal data monetization ecosystem in OSNs and its possible evolutions for increasing privacy and transparency for consumers about their OSN presence. In the last part of the paper, we describe the USEMP scoring framework for personal information disclosure and data value that can assist users to better perceive how their privacy is affected by their OSN presence and what the value of their OSN activities is.
