Supply Chain Management in the Life Science Sector: Does Trust Play a Role?

Supply chain management has emerged as cross functional, cross company concept to improve coordination of entire value chains through coordinated actions of all companies in the value chain. It has received a major push from the availability of Internet-based information and communication technologies. The conditions in certain sectors are favorable for a realization of chain wide supply chain management. In other sectors, however, conditions are more complex and companies and value chains still struggle to exploit the potentials from supply chain management, in particular when it comes to cross enterprise coordination. This paper takes a complex supply network as example and discusses improvement potentials from supply chain management and developments in their implementation as well as barriers to the realization of chain wide supply chain management.supply chain management, trust, life science sector, Agribusiness, Industrial Organization,

An Economic Approach to Article 82

This report argues in favour of an economics-based approach to Article 82, in a way similar to the reform of Article 81 and merger control. In particular, we support an effects-based rather than a form-based approach to competition policy. Such an approach focuses on the presence of anti-competitive effects that harm consumers, and is based on the examination of each specific case, based on sound economics and grounded on facts

Acceptability of road pricing and revenue use in the Netherlands

It is generally acknowledged that the implementation of other, more efficient, road pricing measures meet public resistance and that acceptability is nowadays one of the major barriers to successful implementation. Despite the fact that politicians and the public regard transport problems as very urgent and important, people do have concerns about road pricing, resulting in low acceptance levels. This paper presents the empirical results of a questionnaire among Dutch commuters regularly facing congestion asking for their opinion (in terms of acceptance) on road pricing measures and revenue use targets. We find that road pricing is in general not very acceptable and that revenue use is important for the explanation of the level of acceptance. Road pricing is more acceptable when revenues are used to replace existing car taxation or to lower fuel taxes. Moreover, personal characteristics of the respondent have an impact on support levels. Higher educated people, as well as respondents with a higher value of time and with higher perceived effectiveness of the measure, seem to find road pricing measures more acceptable than other people. The same holds for people that receive financial support for their commuting costs and for respondents driving many kilometers in a year. When we ask directly for the acceptability of different types of revenue use (not part of a road pricing measure), again abandoning of existing car (ownership) taxes receives most support whereas the general budget is not acceptable.

Strong Nash Equilibria in Games with the Lexicographical Improvement Property

We introduce a class of finite strategic games with the property that every deviation of a coalition of players that is profitable to each of its members strictly decreases the lexicographical order of a certain function defined on the set of strategy profiles. We call this property the Lexicographical Improvement Property (LIP) and show that it implies the existence of a generalized strong ordinal potential function. We use this characterization to derive existence, efficiency and fairness properties of strong Nash equilibria. We then study a class of games that generalizes congestion games with bottleneck objectives that we call bottleneck congestion games. We show that these games possess the LIP and thus the above mentioned properties. For bottleneck congestion games in networks, we identify cases in which the potential function associated with the LIP leads to polynomial time algorithms computing a strong Nash equilibrium. Finally, we investigate the LIP for infinite games. We show that the LIP does not imply the existence of a generalized strong ordinal potential, thus, the existence of SNE does not follow. Assuming that the function associated with the LIP is continuous, however, we prove existence of SNE. As a consequence, we prove that bottleneck congestion games with infinite strategy spaces and continuous cost functions possess a strong Nash equilibrium

The Veterans Emergency Housing Program

Dynamic spectrum access (DSA) schemes allow the users to share spectrum resources by taking advantage of the variations in spectrum demand over time and space. Carrying out dynamic spectrum allocation centrally, however, can be a complex task. For this reason, distributed schemes in which users can access the available channels independently may be preferable to centralized DSA schemes. Cognitive radio systems, which enable user terminals to sense their environment and form their action accordingly, are particularly well-suited for distributed systems. On the other hand, the freedom in distributed schemes gives the users the option to act selfishly, which has decisive effects on system performance. In this paper we consider a distributed multichannel wireless random access system where users selfishly access the channels in the system. We analyze the behavior of the selfish users by modeling the system as a non-cooperative game and we identify all stable operating points (Nash equilibria) of this game. We then compare the performance of this system with a number of cooperative distributed DSA schemes in terms of user utilities. Our results show that the performance of the selfish multichannel random access system can be comparable to cooperative schemes.QC 20111208. © 2010 IEEE. Personal use of this material is permitted.
