Innovative regulations,incomplete contracts and ownership structure in the water utilities

Using an incomplete contract framework, we analyse new forms of regulation and private participation in public services. This paper explains contractual efficiency in the absence of financially guaranteed investments in public private partnerships. The example of a number of African countries underlines how a series of national, normative law reforms can give rise to innovations in approaches to regulation. This new hybrid form of regulation, inspired by a French regulation approach combining commission regulation and franchise bidding, could be more effective than previous approaches to regulation, in the sense of being more stable and more closely aligned with stakeholder expectations. This approach to regulation would appear to be more efficient economically, while integrating the objectives of solidarity tariffs and social water access connections. Based on these analyses, our results show (1) the impact on the robustness of new lease contracts on financing constraints, and (2) the advantages of Asset Owner Companies that reconcile explicit commitments and special purposes. We demonstrate that this achieves optimum efficiency by encouraging parties to determine jointly the optimal level of costs and investment. In addition, the mechanism fosters discussion about the possibility of institutionalizing Asset Owner Companies by predetermining the distribution of risk in lease contracts.     

Social Utility in Ultimatum Bargaining

In this article we will provide an overview of factors that influence the weight that self-interest and equity related motives receive in ultimatum bargaining. These factors are grouped into three main categories: factors relating to the context of the game, factors relating to the parties involved, and factors related to characteristics of the game. Results of the studies are discussed in relation to the concept of social utility. The authors point out possible omissions in the literature—especially the lack of interest for the behavior of recipients—and recommend directions for future research.     

Implantation of an RFID-tag into human molars to reduce hard forensic identification labor. Part 2: physical properties

Modifying and implanting existing RFID-tags into extracted human molars was described previously [P. Thevissen, G. Poelman, B. Puers, M. De Cooman, G. Willems, Implantation of RFID-tag into human molars to reduce hard forensic identification labor. Part 1. Working principle, Forensic Sci. Int. 156 (2006)]. Maximal vertical occlusal load during which the implanted RFID-tags remain active was evaluated in vitro. The temperature dependency of the implanted RFID-tags was studied on the extracted teeth to find out the maximal obtainable temperature before failure and a test with embedded thermistors to verify temperature distributions. The maximal working temperature of the implanted RFID-tags was revealed and gave indications for the set-up of measuring intra oral and intra tooth temperature during the cremation of a human body. Fatigue was induced on the implanted teeth by thermocycling. The results of this investigation showed the need of putting an extra insulating layer around the modified tags before implantation. The different in vitro tests indicated that the implanted RFID-tags can support certain oral and forensic circumstances.
