Trade Costs, International Competition and Selection: The Effects of Unionisation on Market Size

Within a two-country model of international trade in which heterogeneous firms face firm-specific unions, we study the effects of different forms of trade liberalisation on market structure and competitive selection in the presence of inter-country asymmetries in size and labour market institutions. For given levels of trade openness, an increase in a country’s relative unions’ strength reduces the average productivity of its domestic producers but increases that of its exporters. Whilst an unfavourable union power differential, by increasing wages, weakens a country’s firms’ competitive position, the higher wages reinforce standard market access mechanisms to give rise to aggregate income effects. When the initial levels of trade openness are sufficiently low, this ‘expansionary’ aggregate effect can attract industry in the country with stronger unions and also result in an increase in the extensive margin of exports. For sufficiently large inter-country differences in the bargaining power of unions, trade liberalization can then result in a pro-variety effect, with an increase in the total availability of varieties to consumers in both countries, regardless of there being inter-country differences in size.

The international trade as the sole engine of growth for an economy

Can international trade act as the sole engine of growth for an economy? If yes, what are the mechanisms through which trade operates in transmitting permanent growth? This paper answers these questions with two simple two-country models, in which only one country enjoys sustained growth in autarky. The models differ in the assumptions on technical change, which is either labour- or capital-augmenting. In both cases, the stagnant economy imports growth by trading. In the first model, growth is transmitted because of permanent increases in the trade volume. In the alternative framework, the stagnant economy imports sustained growth because its terms of trade permanently improve.

Contribution à l'élaboration de mécanismes de détection, de contrôle et de lutte contre le blanchiment d'argent au regard de l'usage des technologies de l'information et de la communication "cas de l'Algérie"

Résumé : Désormais, la lutte contre le blanchiment d'argent constitue une priorité pour les Etats et les gouvernements dans le but, d'une part, de préserver l'économie et l'intégrité des places financières et, d'autre part, de priver les organisations criminelles des ressources financières. Dans ce contexte, la préoccupation majeure des autorités algériennes en charge de la lutte contre ce phénomène est de mettre en place un dispositif capable de détecter les mécanismes de blanchiment, d'en évaluer la menace et sur la base de cette connaissance, de définir et de déployer les moyens de riposte les plus efficaces et efficients. Mais nous constatons que mener des enquêtes de blanchiment en conséquence à un crime sous-jacent a montré ses limites en matière d'établissement de preuves, d'élucidation d'affaires et de recouvrement des avoirs. Par ailleurs, nous pensons qu'il serait plus judicieux de mettre en place en amont un contrôle «systématique» des flux financiers et des opérations inhabituelles et/ou suspectes et de là, identifier d'éventuelles opérations de blanchiment, sans forcément connaître le crime initial, en veillant au maintien de l'équilibre entre le «tout sécuritaire» orienté vers la surveillance accrue des flux et la préservation de la vie privée et des libertés individuelles. Notre thèse apporte un regard critique sur le dispositif actuel de lutte contre le blanchiment existant en Algérie que nous évaluons et sur lequel nous relevons plusieurs lacunes. Pour répondre aux problèmes identifiés nous proposons des solutions stratégiques, organisationnelles, méthodologiques et technologiques intégrées dans un cadre opérationnel cohérent au niveau national et international.

Globalization and international relations: the Olympic Movement and European Integration

Essay elaborated by Shaelyne Johnson, undergraduate student of Global Studies at the University of California-Santa Barbara, during her internship at CEO-UAB for the academic course 2008/2009. She compares the organisational structure, goals and objectives of the institutions in the Olympic Movement and the European Integration, in order to find connections between both movements which were caused by globalization. The paper begins with an introduction of the changing world nowadays, followed by an overview on the structural similarities in the historical unfolding between these two parallel movements and, before concluding, new means for international relations are considered. This document is available in English through the digital library at the CEO-UAB Portal of Olympic Studies and the digital repository RECERCAT.

Le nombre de reines chez les fourmis et sa conséquence sur l'organisations sociale

Nearly half of all ant species form polygyne societies (cohabitation of more than a single egg-laying queen). These queens are generally smaller and store fewer fat reserves than queens from monogyne colonies. Most queens in polygyne colonies (70-100 pour 100) are inseminated, although this proportion varies among species, and even among populations of the same species. They exhibit mutual tolerance and they all contribute to the reproductive effort of the colony. Nevertheless, their individual fecundity is considerably reduced compared with that of queens from monogyne colonies. This reduction in fecundity seems to be due to some form of mutual inhibition, in some cases the secretion by each female of a substance suppressing egg production in other queens has been implicated. In a few species, queens are organized into a hierarchy such that certain queens lay more eggs than others or even monopolize egg-laying (functional monogyny). Polygyny is linked to a particular life history. It rarely results from the association of several foundresses (primary polygyny). Usually, it is due to the adoption of young queens by an established nest just after a nuptial flight. This secondary polygyny means that the dispersal of the species is limited and is achieved by the budding of a mother nest. Thus colony founding is dependent; with workers accompanying young queens in establishing new colonies. Observation of closely related species exhibiting different social organizations, some monogyne and others polygyne, shows a possible link between queen number and ecological conditions: polygyne forms are more frequent in unstable habitats susceptible to rapid change, such as that caused by human activity. The existence of polygyne societies is an intriguing evolutionary mystery. Research into the origin and maintenance of polygyny focuses on patterns of speciation in relation to queen number and the different theories put forth for the evolution of eusociality, mainly kin selection and mutualism.

International Aid to Tanzania – with some comparisons from Ghana and Uganda

This paper has three principal objectives. First, to review the level of Official Development Assistance (ODA) to Tanzania over the last two to three decades, and to place this into an economic context. This review includes some comparisons with the experience of Ghana and Uganda. Second, to discuss three major issues for the Tanzanian aid: the position of ODA as budget support, corruption, and alignment with the principles of the Paris Declaration on Aid Effectiveness. Third, to review the literature on the Tanzanian aid experience, including a range of official evaluation reports produced by the Tanzanian government and by the donor community. The conclusions, broadly, are that ODA has been at a sustained high level for most of the period reviewed, funding a significant amount of government development expenditure, and that economic growth has been strong, with poverty reduction ‘flat-lining’ in Tanzania but being significant in Ghana and Uganda. Experience with budget support in Tanzania has been mixed, corruption continues as a major concern, and improvements to public finance management have been difficult to achieve. In this context governance adjustments come slowly, requiring patience on the part of both recipient governments and the ODA donor community.

Unionisation, International Integration and Selection

We study how unionisation affects competitive selection between heterogeneous firms when wage negotiations can occur at the firm or at the profit-centre level. With productivity specific wages, an increase in union power has: (i) a selection-softening; (ii) a counter-competitive; (iii) a wage-inequality; and (iv) a variety effect. In a two-country asymmetric setting, stronger unions soften competition for domestic firms and toughen it for exporters. With profit-centre bargaining, we show how trade liberalisation can affect wage inequality among identical workers both across firms (via its effects on competitive selection) and within firms (via wage discrimination across destination markets).

Emissions distribution in post-Kyoto international negotiations: a policy

An abundant scientific literature about climate change economics points out that the future participation of developing countries in international environmental policies will depend on their amount of pay offs inside and outside specific agreements. These studies are aimed at analyzing coalitions stability typically through a game theoretical approach. Though these contributions represent a corner stone in the research field investigating future plausible international coalitions and the reasons behind the difficulties incurred over time to implement emissions stabilizing actions, they cannot disentangle satisfactorily the role that equality play in inducing poor regions to tackle global warming. If we focus on the Stern Review findings stressing that climate change will generate heavy damages and policy actions will be costly in a finite time horizon, we understand why there is a great incentive to free ride in order to exploit benefits from emissions reduction efforts of others. The reluctance of poor countries in joining international agreements is mainly supported by historical responsibility of rich regions in generating atmospheric carbon concentration, whereas rich countries claim that emissions stabilizing policies will be effective only when developing countries will join them.Scholars recently outline that a perceived fairness in the distribution of emissions would facilitate a wide spread participation in international agreements. In this paper we overview the literature about distributional aspects of emissions by focusing on those contributions investigating past trends of emissions distribution through empirical data and future trajectories through simulations obtained by integrated assessment models. We will explain methodologies used to elaborate data and the link between real data and those coming from simulations. Results from this strand of research will be interpreted in order to discuss future negotiations for post Kyoto agreements that will be the focus of the next. Conference of the Parties in Copenhagen at the end of 2009. A particular attention will be devoted to the role that technological change will play in affecting the distribution of emissions over time and to how spillovers and experience diffusion could influence equality issues and future outcomes of policy negotiations.

International Institutions as Solutions to Underlying Games of Cooperation

This Working Paper was presented at the international workshop "Game Theory in International Relations at 50", organized and coordinated by Professor Jacint Jordana and Dr. Yannis Karagiannis at the Institut Barcelona d'Estudis Internacionals on May 22, 2009. The day-long Workshop was inspired by the desire to honour the ground-breaking work of Professor Thomas Schelling in 1959-1960, and to understand where the discipline International Relations lies today vis-à-vis game theory.

Clinical presentation, etiology, and outcome of infective endocarditis in the 21st century: the International Collaboration on Endocarditis-Prospective Cohort Study.

We sought to provide a contemporary picture of the presentation, etiology, and outcome of infective endocarditis (IE) in a large patient cohort from multiple locations worldwide. Prospective cohort study of 2781 adults with definite IE who were admitted to 58 hospitals in 25 countries from June 1, 2000, through September 1, 2005. The median age of the cohort was 57.9 (interquartile range, 43.2-71.8) years, and 72.1% had native valve IE. Most patients (77.0%) presented early in the disease (<30 days) with few of the classic clinical hallmarks of IE. Recent health care exposure was found in one-quarter of patients. Staphylococcus aureus was the most common pathogen (31.2%). The mitral (41.1%) and aortic (37.6%) valves were infected most commonly. The following complications were common: stroke (16.9%), embolization other than stroke (22.6%), heart failure (32.3%), and intracardiac abscess (14.4%). Surgical therapy was common (48.2%), and in-hospital mortality remained high (17.7%). Prosthetic valve involvement (odds ratio, 1.47; 95% confidence interval, 1.13-1.90), increasing age (1.30; 1.17-1.46 per 10-year interval), pulmonary edema (1.79; 1.39-2.30), S aureus infection (1.54; 1.14-2.08), coagulase-negative staphylococcal infection (1.50; 1.07-2.10), mitral valve vegetation (1.34; 1.06-1.68), and paravalvular complications (2.25; 1.64-3.09) were associated with an increased risk of in-hospital death, whereas viridans streptococcal infection (0.52; 0.33-0.81) and surgery (0.61; 0.44-0.83) were associated with a decreased risk. In the early 21st century, IE is more often an acute disease, characterized by a high rate of S aureus infection. Mortality remains relatively high.

Management des entreprises de l'économie sociale et solidaire Identités plurielles et spécificités

L'Économie Sociale et Solidaire (ESS) représente aujourd'hui, en Europe, près de 10 % de l'emploi total et même plus dans certains pays, dont la France. Avec la crise, ce secteur prend une importance sociale, économique et politique croissante. La gestion des coopératives, mutuelles, fondations et associations est ainsi doublement interrogée en interne vis-à-vis de leurs « propriétaires » disposant de motivations particulières (socioéconomiques) et vis-à-vis de leurs communautés et territoires (relations aux partenaires publics et aux citoyens). C'est pourquoi la performance de ces organisations prend nécessairement une dimension sociale, voire sociétale. Les logiques de fonctionnement et d'action des managers de l'ESS sont, elles aussi, souvent particulières, hybrides et parfois paradoxales. Elles remettent en cause les découpages et frontières classiques du management, ainsi que les modèles de rationalité associés (public/privé, marchand/non-marchand, intérêt collectif/intérêts particuliers...). Face à une telle complexité, les principes et les outils de gestion de ces entreprises sont-ils alors spécifiques ? Ces entreprises sont-elles à l'origine d'innovations managériales et sociales particulières ? Comment concilier solidarité et efficacité dans un univers de plus en plus concurrentiel ? L'évolution marchande et financière, comme les problématiques de développement durable, interrogent également le mode de fonctionnement et l'avenir de ces organisations. L'objectif de cet ouvrage collectif, auquel ont contribué des experts du management des entreprises de l'économie sociale qui ont participé à un colloque international - soutenu par le Crédit Mutuel - sur le sujet, est d'apporter des réponses quant à la manière de renouveler les stratégies et les modèles de management, sans pour autant renier les valeurs et les principes fondamentaux de l'ESS. Il s'adresse aux étudiants et aux professionnels travaillant dans le secteur de l'économie sociale et solidaire (coopératives, mutuelles, associations et fondations) et intéressera également tous les managers et étudiants en management.

Protein interaction data curation: the International Molecular Exchange (IMEx) consortium.

The International Molecular Exchange (IMEx) consortium is an international collaboration between major public interaction data providers to share literature-curation efforts and make a nonredundant set of protein interactions available in a single search interface on a common website (http://www.imexconsortium.org/). Common curation rules have been developed, and a central registry is used to manage the selection of articles to enter into the dataset. We discuss the advantages of such a service to the user, our quality-control measures and our data-distribution practices.
