Dynamic adaptation of stability periods for service level agreements

A QoS adaptation to dynamically changing system conditions that takes into consideration the user’s constraints on the stability of service provisioning is presented. The goal is to allow the system to make QoS adaptation decisions in response to fluctuations in task traffic flow, under the control of the user. We pay special attention to the case where monitoring the stability period and resource load variation of Service Level Agreements for different types of services is used to dynamically adapt future stability periods, according to a feedback control scheme. System’s adaptation behaviour can be configured according to a desired confidence level on future resource usage. The viability of the proposed approach is validated by preliminary experiments.

The simple economics of risk-sharing agreements between the NHS and the pharmaceutical industry

The Janssen-Cilag proposal for a risk-sharing agreement regarding bortezomib received a welcome signal from NICE. The Office of Fair Trading report included risk-sharing agreements as an available tool for the National Health Service. Nonetheless, recent discussions have somewhat neglected the economic fundamentals underlying risk-sharing agreements. We argue here that risk-sharing agreements, although attractive due to the principle of paying by results, also entail risks. Too many patients may be put under treatment even with a low success probability. Prices are likely to be adjusted upward, in anticipation of future risk-sharing agreements between the pharmaceutical company and the third-party payer. An available instrument is a verification cost per patient treated, which allows obtaining the first-best allocation of patients to the new treatment, under the risk sharing agreement. Overall, the welfare effects of risk-sharing agreements are ambiguous, and care must be taken with their use.

Licensing in an international triopoly

We study the effects of entry of two foreign firms on domestic welfare in the presence of licensing, when the incumbent is technologically superior to the entrants. We consider two different situations: (i) the cost-reducing innovation is licensed to both entrants; (ii) the cost- reducing innovation is licensed to just one of the entrants. We analyse three kind of license: (lump- sum) fixed-fee; (per-unit) royalty; and two-part tariff, that is a combination of a fixed-fee and a royalty. We prove that a two part tariff is never an optimal licensing scheme for the incumbent. Moreover, (i) when the technology is licensed to the two entrants, the optimal contract consists of a licensing with only output royalty; and (ii) when the technology is licensed to just one of the entrants, the optimal contract consists of a licensing with only a fixed-fee.

Per-unit royalty and fixed-fee licensing in a differentiated Stackelberg model

In the present paper we consider a differentiated Stackelberg model, when the leader firm engages in an R&D process that gives an endogenous cost-reducing innovation. The aim is to study the licensing of the cost-reduction by a per-unit royalty and a fixed-fee. We analyse the implications of these types of licensing contracts over the R&D effort, the profits of the firms, the consumer surplus and the social welfare. By using comparative static analysis, we conclude that the degree of the differentiation of the goods plays an important role in the results.

The Pursuit of Efficient Copyright Licensing : How Some Rights Reserved Attempts to Solve the Problems of All Rights Reserved

This dissertation analyses the growing pool of copyrighted works, which are offered to the public using Creative Commons licensing. The study consist of analysis of the novel licensing system, the licensors, and the changes of the "all rights reserved" —paradigm of copyright law. Copyright law reserves all rights to the creator until seventy years have passed since her demise. Many claim that this endangers communal interests. Quite often the creators are willing to release some rights. This, however, is very difficult to do and needs help of specialized lawyers. The study finds that the innovative Creative Commons licensing scheme is well suited for low value - high volume licensing. It helps to reduce transaction costs on several le¬vels. However, CC licensing is not a "silver bullet". Privacy, moral rights, the problems of license interpretation and license compatibility with other open licenses and collecting societies remain unsolved. The study consists of seven chapters. The first chapter introduces the research topic and research questions. The second and third chapters inspect the Creative Commons licensing scheme's technical, economic and legal aspects. The fourth and fifth chapters examine the incentives of the licensors who use open licenses and describe certain open business models. The sixth chapter studies the role of collecting societies and whether two institutions, Creative Commons and collecting societies can coexist. The final chapter summarizes the findings. The dissertation contributes to the existing literature in several ways. There is a wide range of prior research on open source licensing. However, there is an urgent need for an extensive study of the Creative Commons licensing and its actual and potential impact on the creative ecosystem.

Bargaining Power Dynamics and the Negotiation of Commercial Rights and Obligations: A Case of Athlete Agreements

This qualitative case study explored how the structural power imbalance in high performance sport influenced the bargaining process and resulting commercial rights and obligations of a single Canadian national sport organization’s (NSO1) Athlete Agreement. Principles comprising the doctrine of unconscionability, specifically the identification of a power imbalance between contracting parties, and the exploration of how that power imbalance influenced the terms of the contract, provided a framework to analyze factors influencing the commercial contents of NSO1’s Athlete Agreement. The results of this analysis revealed that despite the overarching influence of the inherent structural power imbalance on all aspects of NSO1 and its membership, an athletes’ level of commercial appeal can reach such heights as to balance the bargaining positions of both parties and subsequently influence the commercial contents of the Athlete Agreement.

Rights in Asylum Sharing and Other Human Transfer Agreements

The article sets out the concept of a State-to-State human transfer agreement of which extradition and deportation are specialised forms. Asylum sharing agreements are other variations which the article explores in more detail. Human transfer agreements always affect at least the right to liberty and the freedom of movement, but other rights will also be at issue to some extent. The article shows how human rights obligations limit State discretion in asylum sharing agreements and considers how past and present asylum sharing arrangements in Europe and North America deal with these limits, if at all. The article suggests changes in the way asylum sharing agreements are drafted: for example, providing for a treaty committee would allow existing agreements to better conform to international human rights instruments and would facilitate State compliance to their human rights obligations.

The Effects of the Length of the Period of Commitment on the Size of Stable International Environmental Agreements

This paper extends the standard model of self-enforcing dynamic international environmental agreements by allowing the length of the period of commitment of such agreements to vary as a parameter. It analyzes the pattern of behavior of the size of stable coalitions, the stock of pollutant and the emission rate as a function of the length of the period of commitment. It is shown that the length of the period of commitment can have very significant effects on the equilibrium. Three distinct intervals for the length of the period of commitment are identified, across which the equilibrium and its dynamic behavior differ considerably. Whereas for sufficiently high values of the period of commitment only self-enforcing agreements of two countries are possible, for sufficiently low such values full cooperation can be generated. Lengths of periods of commitment between those two thresholds are characterized by an inverse relationship between the length of commitment and the membership size of the agreement. This suggests that considerable attention should be given to the determination of the length of such international agreements.

Agreements with overlapping coalitions

Dans certaines circonstances, des actions de groupes sont plus performantes que des actions individuelles. Dans ces situations, il est préférable de former des coalitions. Ces coalitions peuvent être disjointes ou imbriquées. La littérature économique met un fort accent sur la modélisation des accords où les coalitions d’agents économiques sont des ensembles disjoints. Cependant on observe dans la vie de tous les jours que les coalitions politiques, environnementales, de libre-échange et d’assurance informelles sont la plupart du temps imbriquées. Aussi, devient-il impératif de comprendre le fonctionnement économique des coalitions imbriquées. Ma thèse développe un cadre d’analyse qui permet de comprendre la formation et la performance des coalitions même si elles sont imbriquées. Dans le premier chapitre je développe un jeu de négociation qui permet la formation de coalitions imbriquées. Je montre que ce jeu admet un équilibre et je développe un algorithme pour calculer les allocations d’équilibre pour les jeux symétriques. Je montre que toute structure de réseau peut se décomposer de manière unique en une structure de coalitions imbriquées. Sous certaines conditions, je montre que cette structure correspond à une structure d’équilibre d’un jeu sous-jacent. Dans le deuxième chapitre j’introduis une nouvelle notion de noyau dans le cas où les coalitions imbriquées sont permises. Je montre que cette notion de noyau est une généralisation naturelle de la notion de noyau de structure de coalitions. Je vais plus loin en introduisant des agents plus raffinés. J’obtiens alors le noyau de structure de coalitions imbriquées que je montre être un affinement de la première notion. Dans la suite de la thèse, j’applique les théories développées dans les deux premiers chapitres à des cas concrets. Le troisième chapitre est une application de la relation biunivoque établie dans le premier chapitre entre la formation des coalitions et la formation de réseaux. Je propose une modélisation réaliste et effective des assurances informelles. J’introduis ainsi dans la littérature économique sur les assurances informelles, quatre innovations majeures : une fusion entre l’approche par les groupes et l’approche par les réseaux sociaux, la possibilité d’avoir des organisations imbriquées d’assurance informelle, un schéma de punition endogène et enfin les externalités. Je caractérise les accords d’assurances informelles stables et j’isole les conditions qui poussent les agents à dévier. Il est admis dans la littérature que seuls les individus ayant un revenu élevé peuvent se permettre de violer les accords d’assurances informelles. Je donne ici les conditions dans lesquelles cette hypothèse tient. Cependant, je montre aussi qu’il est possible de violer cette hypothèse sous d’autres conditions réalistes. Finalement je dérive des résultats de statiques comparées sous deux normes de partage différents. Dans le quatrième et dernier chapitre, je propose un modèle d’assurance informelle où les groupes homogènes sont construits sur la base de relations de confiance préexistantes. Ces groupes sont imbriqués et représentent des ensembles de partage de risque. Cette approche est plus générale que les approches traditionnelles de groupe ou de réseau. Je caractérise les accords stables sans faire d’hypothèses sur le taux d’escompte. J’identifie les caractéristiques des réseaux stables qui correspondent aux taux d’escomptes les plus faibles. Bien que l’objectif des assurances informelles soit de lisser la consommation, je montre que des effets externes liés notamment à la valorisation des liens interpersonnels renforcent la stabilité. Je développe un algorithme à pas finis qui égalise la consommation pour tous les individus liés. Le fait que le nombre de pas soit fini (contrairement aux algorithmes à pas infinis existants) fait que mon algorithme peut inspirer de manière réaliste des politiques économiques. Enfin, je donne des résultats de statique comparée pour certaines valeurs exogènes du modèle.
