Rules of origin in services : a case study of five ASEAN countries
Full text linkAn important question in the design of bilateral and regional free trade agreements (FTAs) covering services is to what extent nonmembers benefit from the trade preferences that are negotiated among members. This question is resolved through services rules of origin. The restrictiveness of rules of origin determines the degree of preferences entailed in market opening commitments, shaping the bargaining incentives of FTAs and their eventual economic effects. Even though the number of FTAs in services has increased rapidly in recent years, hardly any research is available that can guide policymakers on the economic implications of different rules of origin. After outlining the key economic tradeoffs and options for rules of origin in services, the paper summarizes the main findings of a research project that has assessed the rules of origin question for five countries in the ASEAN region. For selected service subsectors and a number of criteria for rules or origin, simulation exercises evaluated which service providers would or would not be eligible for preferences negotiated under a FTA. Among other findings, the simulation results point to the binding nature of a domestic ownership or control requirement and, for the specific case of financial services, a requirement of incorporation.Free Trade,Trade Law,Trade and Services,Economic Theory&Research,Trade Policy
Libéralisation commerciale, allocation du travail et dynamique des revenus au Vietnam
Full text linkThe objectives of the current thesis are to investigate evolutions of the labor market since Doi Moi and impacts from the international integration of Vietnam’s economy, with focuses on a distinction of formal and informal sectors. In the current state of the thesis, the impacts of the trade liberalization and the increases in the minimum wages of the domestic sectors are studied. Indeed, the latter factor, the increase in the minimum wages, can be also considered as a factor relating to the international integration as it followed Viet Nam’s commitments under the WTO accession. For the impacts of the trade liberalization, the thesis investigates the impacts on labor allocations between different types of employments including wage work in the formal sectors and household businesses as well as self-employments in manufacturing sectors. The impacts on income differentials across the types of employments are also exploited. For the impacts of the increases in the minimum wages, the thesis exploits the effects on the total employments, movements between the formal sectors and other types of employments, wage distributions within the formal and informal sectors and wage gaps between the two sectors at different percentiles. Chapter 1. Trade liberalization, labor allocation and income dynamics in Vietnam Abstract This study seeks to answer two inter-related questions for Viet Nam: (i) how trade liberalization affects the allocation of workers across self-employment, wage work in household businesses and wage work in the formal sector (private, foreign invested and state enterprises); and (ii) income differentials between these kinds of employment. An extension of the two-step model in Goldberg and Pavcnik (2003) and its modification are employed to answer the questions. Data is sourced from five Viet Nam Household Living Standard Surveys from 2002 to 2010 and available measures of the trade liberalization in Viet Nam. The results indicate that the trade liberalization does not have significant impacts on income differentials between types of employments. Meanwhile, increases in exposing to the international trade reduce wage works in household businesses, compared with that in the formal sectors. The increase in the trade liberalization also has impacts on self-employments but it seems that the directions of impacts depend on statues of net import or net export of industries of Viet Nam. Chapter 2. Impacts of unification of minimum wages across sectors on labor allocations and income dynamics in Vietnam Abstract Rates of minimum wages in Viet Nam have increased drastically since 2009 as commitments of unification between those in FDI and domestic sectors under the WTO accession. This growth has been considered as being higher to productivity growth of the economy. Employing data of Vietnam Labor Force Surveys and Household Living Standard Surveys from 2010 to 2014, the current paper investigates impacts of the minimum wages on employment statues, wage distributions in formal and informal sectors as well as wage gap between the two sectors. The results imply that the minimum wages do not have significant impacts on the total employments of the whole population. This result is somewhat different from those reported in previous studies for Viet Nam. Our different specifications detect that the differences in the results are attributed to inclusions of trends in studying. Similar to the work of Hansen et al. (2015), the results indicates that that the minimum wages positively affects the wage distribution in the formal sectors. However, we find that the effects do not stop at the median as the result of Hansen et al. but also on higher percentiles. Finally, the minimum wages increases the wage gap between the formal and informal sectors with stronger effects at higher percentiles of the wage distribution.Les objectifs de notre thèse sont d'étudier les évolutions du marché du travail depuis Doï Moï (la réforme économique au VN en 1986) et les impacts de l'intégration internationale de l'économie du Vietnam, en mettant l'accent sur une distinction des secteurs formel et informel. Dans notre thèse, nous étudions les impacts de la libéralisation commerciale et l'augmentation des salaires minimums dans les secteurs domestiques. Ce dernier peut également être considéré comme un facteur relatif à l'intégration internationale puisqu'il a suivi les engagements du Vietnam dans le cadre de l'adhésion à WTO. Pour les impacts de la libéralisation commerciale, nous examinons les effets sur les allocations de main-d'œuvre entre différents types d'emplois, y compris le travail salarié dans les secteurs formels et les entreprises ménagères, ainsi que les emplois autonomes dans les secteurs manufacturiers. Les impacts sur les écarts de revenus dans les différents types d'emplois sont également exploités. Pour les impacts de l'augmentation des salaires minimums, nous exploitons les effets sur le total des emplois, les mouvements entre les secteurs formels et les autres types d'emplois, la répartition des salaires dans les secteurs formel et informel et les écarts de salaire entre les deux secteurs à différents centiles. Chapitre 1. Libéralisation commerciale, allocation du travail et dynamique des revenus au Vietnam Abstrait Cette étude vise à répondre à deux questions inter-liées au Viet Nam: (i) comment la libéralisation commerciale influence l'allocation des travailleurs, entre travail indépendant, travail salarié dans les entreprises familiales et le travail salarié dans le secteur formel (entreprises privées, étrangères et publiques); et (ii) les écarts de revenus entre ces types d'emplois. Une extension du modèle « deux étapes » de Goldberg et Pavcnik (2003) et sa modification sont utilisées pour répondre aux questions. Les données proviennent de cinq enquêtes traditionnelles sur le vieillissement du ménage du Viet Nam de 2002 à 2010 et des mesures disponibles de la libéralisation commerciale au Viet Nam. Les résultats indiquent que la libéralisation commerciale n'a pas d'impact significatif sur les écarts de revenus entre les types d'emplois. Parallèlement, les augmentations de l'exposition au commerce international réduisent les salaires dans les entreprises familiales, par rapport à celles des secteurs formels. L'augmentation de la libéralisation commerciale a également des répercussions sur les emplois autonomes, mais il semble que les orientations des impacts dépendent des statuts de l'importation nette ou de l'exportation nette d'industries du Viet Nam. Chapitre 2. Impacts de l'unification des salaires minimum entre les secteurs sur les allocations de travail et la dynamique des revenus au Vietnam Abstrait Les taux de salaire minimum au Viet Nam ont augmenté considérablement depuis 2009 en tant qu'engagements d'unification entre les IDE et les secteurs domestiques dans le cadre de l'adhésion à WTO. Cette croissance a été considérée comme supérieure à la croissance de la productivité de l'économie. En utilisant les données des Enquêtes sur la population active du Vietnam et les enquêtes sur le niveau de vie des ménages de 2010 à 2014, le document actuel examine les répercussions des salaires minimum sur les statuts de l'emploi, la répartition des salaires dans les secteurs formel et informel ainsi que les écarts de salaire entre les deux secteurs. Les résultats impliquent que le salaire minimum n'a pas d’effet significatif sur l'ensemble des emplois de l'ensemble de la population. Ce résultat est quelque peu différent de ceux rapportés dans des études antérieures pour le Viet Nam
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Weighting deprivations using subjective well-being: An application to the Multidimensional Child Poverty Index in Vietnam
No full textAlthough multidimensional approach to study child poverty has received growing attention, weights of different dimensions in constructing single aggregation indices have not been properly investigated. Using Young Livesdata, this study attempts to fill this gap by examining a weight estimation method which takes into account the children’s perspectives. This approach consists of computing analytical weights from estimated parameters of asubjective well-being regression model, where children’s subjective well-being is explained by their achievement in dimensions included in multidimensional poverty indices. By doing so, weights reflect valuejudgments of children on what is a good life and are not based on a normative approach. Estimation resultsindicate that revealed preferences of children change overtime and across sub-groups of children. More importantly, this paper demonstrates that children do not give the same value to all dimensions, contrary to whatthe most common approach to calculate weights is supposing. Children then attach more importance to deprivations such as shelter, water and sanitation deprivations, which impact immediately their well-being thanto deprivations which may affect negatively their well-being in the long-term, with the exception of education for some groups of children.L’approche multidimensionnelle pour étudier la pauvreté des enfants a reçu une attention croissante. Pourtant, la question de comment pondérer les différentes dimensions de la pauvreté dans la construction d’un indicateursynthétique de pauvreté reste encore largement sous-étudiée. A partir des données Young Lives, cette étude s’attache à combler cette lacune en examinant une méthode d'estimation des poids qui prend en compte lesperceptions des enfants. Cette approche consiste à calculer le poids à partir des paramètres estimés d'un modèle expliquant le bien-être subjectif des enfants par leur réalisation dans les différentes dimensions de la pauvretéincluse dans l’indice synthétique. Les poids ainsi obtenus reflètent les valeurs des enfants sur ce qu’ils considèrent bien vivre, sans apporter de jugement normatif comme le fait l’approche donnant la même valeur àtoutes les dimensions qui est actuellement suivie au Vietnam. Les résultats indiquent que les préférences révélées des enfants varient au cours du temps et entre sous-groupes d'enfants. Surtout, cette étude démontre queles enfants ne donnent pas la même valeur à toutes les dimensions. Ils attachent plus d'importance à des privations qui ont un impact immédiatement leur bien-être telles que celles relatives aux conditions d’habitat, à l’accès à l’eau, à l’assainissement qu’aux privations qui impactent leur bien-être à plus long-terme, à l'exception de l'éducation pour certains groupes d'enfants
