Essays in theoretical and applied macroeconomics

Cette thèse s’articule autour de trois chapitres indépendants qui s’inscrivent dans les champs de la macroéconomie, de l’économie monétaire et de la finance internationale. Dans le premier chapitre, je construis un modèle néo-keynesien d’équilibre général sous incertitude pour examiner les implications de la production domestique des ménages pour la politique monétaire. Le modèle proposé permet de reconcilier deux faits empiriques majeurs: la forte sensibilité du produit intérieur brut aux chocs monétaires (obtenue à partir des modèles VAR), et le faible degré de rigidité nominale observé dans les micro-données. Le deuxième chapitre étudie le role de la transformation structurelle (réallocation de la main d’oeuvre entre secteurs) sur la volatilité de la production aggregée dans un panel de pays. Le troisième chapitre quant à lui met en exergue l’importance de la cartographie des échanges commerciaux pour le choix entre un régime de change fixe et l’arrimage à un panier de devises. "Household Production, Services and Monetary Policy" (Chapitre 1) part de l’observation selon laquelle les ménages peuvent produire à domicile des substituts aux services marchands, contrairement aux biens non durables qu’ils acquièrent presque exclusivement sur le marché. Dans ce contexte, ils procèdent à d’importants arbitrages entre produire les services à domicile ou les acquerir sur le marché, dépendamment des changements dans leur revenu. Pour examiner les implications de tels arbitrages (qui s’avèrent être importants dans les micro-données) le secteur domestique est introduit dans un modèle néo-keyenesien d’équilibre général sous incertitude à deux secteurs (le secteur des biens non durables et le secteur des services) autrement standard. Je montre que les firmes du secteur des services sont moins enclin à changer leurs prix du fait que les ménages ont l’option de produire soit même des services substituts. Ceci se traduit par la présence d’un terme endogène supplémentaire qui déplace la courbe de Phillips dans ce secteur. Ce terme croit avec le degré de substituabilité qui existe entre les services produits à domicile et ceux acquis sur le marché. Cet accroissement de la rigidité nominale amplifie la sensibilité de la production réelle aux chocs monétaires, notamment dans le secteur des services, ce qui est compatible avec l’évidence VAR selon laquelle les services de consommation sont plus sensibles aux variations de taux d’intérêt que les biens non durables. "Structural Transformation and the Volatility of Aggregate Output: A Cross-country Analysis" (Chapitre 2) est basée sur l’évidence empirique d’une relation négative entre la part de la main d’oeuvre allouée au secteur des services et la volatilité de la production aggrégée, même lorsque je contrôle pour les facteurs tels que le développement du secteur financier. Ce resultat aggregé est la conséquence des développements sectoriels: la productivité de la main d’oeuvre est beaucoup plus volatile dans l’agriculture et les industries manufacturières que dans les services. La production aggregée deviendrait donc mécaniquement moins volatile au fur et à mesure que la main d’oeuvre se déplace de l’agriculture et de la manufacture vers les services. Pour évaluer cette hypothèse, je calibre un modèle de transformation structurelle à l’économie américaine, que j’utilise ensuite pour générer l’allocation sectorielle de la main d’oeuvre dans l’agriculture, l’industrie et les services pour les autres pays de l’OCDE. Dans une analyse contre-factuelle, le modèle est utlisé pour restreindre la mobilité de la main d’oeuvre entre secteurs de façon endogène. Les calculs montrent alors que le déplacement de la main d’oeuvre vers le secteur des services réduit en effet la volatilité de la production aggregée. "Exchange Rate Volatility under Alternative Peg Regimes: Do Trade Patterns Matter?" (Chapitre 3) est une contribution à la litterature économique qui s’interesse au choix entre divers regimes de change. J’utilise les données mensuelles de taux de change bilatéraux et de commerce extérieur entre 1980 et 2010 pour les pays membre de l’Union Economique et Monétaire Ouest Africaine (UEMOA). La monnaie de ces pays (le franc CFA) est arrimée au franc Francais depuis le milieu des années 40 et à l’euro depuis son introduction en 1999. Au moment de l’arrimage initial, la France était le principal partenaire commercial des pays de l’UEMOA. Depuis lors, et plus encore au cours des dix dernières années, la cartographie des échanges de l’union a significativement changé en faveur des pays du groupe des BICs, notamment la Chine. Je montre dans ce chapitre que l’arrimage à un panier de devises aurait induit une volatilité moins pronnoncée du taux de change effectif nominal du franc CFA au cours de la décennie écoulée, comparé à la parité fixe actuelle. Ce chapitre, cependant, n’aborde pas la question de taux de change optimal pour les pays de l’UEMOA, un aspect qui serait intéressant pour une recherche future.

Re-engineering and Re-defining University Libraries in the context of modern Information and Communication Technologies: a study with special reference to the University Libraries in Kerala

Information and communication technologies are the tools that underpin the emerging “Knowledge Society”. Exchange of information or knowledge between people and through networks of people has always taken place. But the ICT has radically changed the magnitude of this exchange, and thus factors such as timeliness of information and information dissemination patterns have become more important than ever.Since information and knowledge are so vital for the all round human development, libraries and institutions that manage these resources are indeed invaluable. So, the Library and Information Centres have a key role in the acquisition, processing, preservation and dissemination of information and knowledge. ln the modern context, library is providing service based on different types of documents such as manuscripts, printed, digital, etc. At the same time, acquisition, access, process, service etc. of these resources have become complicated now than ever before. The lCT made instrumental to extend libraries beyond the physical walls of a building and providing assistance in navigating and analyzing tremendous amounts of knowledge with a variety of digital tools. Thus, modern libraries are increasingly being re-defined as places to get unrestricted access to information in many formats and from many sources.The research was conducted in the university libraries in Kerala State, India. lt was identified that even though the information resources are flooding world over and several technologies have emerged to manage the situation for providing effective services to its clientele, most of the university libraries in Kerala were unable to exploit these technologies at maximum level. Though the libraries have automated many of their functions, wide gap prevails between the possible services and provided services. There are many good examples world over in the application of lCTs in libraries for the maximization of services and many such libraries have adopted the principles of reengineering and re-defining as a management strategy. Hence this study was targeted to look into how effectively adopted the modern lCTs in our libraries for maximizing the efficiency of operations and services and whether the principles of re-engineering and- redefining can be applied towards this.Data‘ was collected from library users, viz; student as well as faculty users; library ,professionals and university librarians, using structured questionnaires. This has been .supplemented by-observation of working of the libraries, discussions and interviews with the different types of users and staff, review of literature, etc. Personal observation of the organization set up, management practices, functions, facilities, resources, utilization of information resources and facilities by the users, etc. of the university libraries in Kerala have been made. Statistical techniques like percentage, mean, weighted mean, standard deviation, correlation, trend analysis, etc. have been used to analyse data.All the libraries could exploit only a very few possibilities of modern lCTs and hence they could not achieve effective Universal Bibliographic Control and desired efficiency and effectiveness in services. Because of this, the users as well as professionals are dissatisfied. Functional effectiveness in acquisition, access and process of information resources in various formats, development and maintenance of OPAC and WebOPAC, digital document delivery to remote users, Web based clearing of library counter services and resources, development of full-text databases, digital libraries and institutional repositories, consortia based operations for e-journals and databases, user education and information literacy, professional development with stress on lCTs, network administration and website maintenance, marketing of information, etc. are major areas need special attention to improve the situation. Finance, knowledge level on ICTs among library staff, professional dynamism and leadership, vision and support of the administrators and policy makers, prevailing educational set up and social environment in the state, etc. are some of the major hurdles in reaping the maximum possibilities of lCTs by the university libraries in Kerala. The principles of Business Process Re-engineering are found suitable to effectively apply to re-structure and redefine the operations and service system of the libraries. Most of the conventional departments or divisions prevailing in the university libraries were functioning as watertight compartments and their existing management system was more rigid to adopt the principles of change management. Hence, a thorough re-structuring of the divisions was indicated. Consortia based activities and pooling and sharing of information resources was advocated to meet the varied needs of the users in the main campuses and off campuses of the universities, affiliated colleges and remote stations. A uniform staff policy similar to that prevailing in CSIR, DRDO, ISRO, etc. has been proposed by the study not only in the university libraries in kerala but for the entire country.Restructuring of Lis education,integrated and Planned development of school,college,research and public library systems,etc.were also justified for reaping maximum benefits of the modern ICTs.

Understanding UK construction professional services exports: definitions and characteristics

Services are very important to the UK balance of trade; a surplus has been recorded for trade in services every year since 1966. Construction professional services exports (CPS), which cover architecture, engineering and surveying (AES), have also increased, contributing over £3bn to the UK trade balance in 2007. The changing environment of construction professional services exports complicates the validity of the characteristics and definitions of services as described in the research literature and official export statistics. Through semi-structured interviews undertaken with large consulting engineers and a round-table discussion with industry and government representatives, the research found that the impact of globalisation and the changes in the construction business environment, such as increasing foreign ownership and changing forms of procurement, are not fully reflected in the official statistics. There have also been rapid changes in technology, procurement and methods of delivery which have impacted exporting AES firms and a more appropriate set of characteristics is needed to better reflect the project-specific and knowledge-intensive nature of AES firms.
