Book Description
L'objectif de cette thèse est d'étudier l'impact des technologies de l'information et de la communication (TIC) sur les coûts de transaction. Elle comporte cinq chapitres. Le premier est consacré essentiellement au développement de la « nouvelle économie », lié à la démocratisation de l'usage des TIC. Or, ces TIC affectent aussi l'environnement informationnel des agents et la nature de leur rationalité, déterminants essentiels des coûts de transaction. Le second chapitre rappelle donc les raisons de l'existence de la théorie des coûts de transaction, ainsi que ses principaux concepts et hypothèses. Quant au troisième chapitre, il démontre comment les TIC réduisent ces coûts de transaction. Ces derniers sont décomposés en coûts de coordination et coûts de motivation. On démontre que les TIC réduisent les coûts de coordination en améliorant l'efficience économique située au niveau de l'amélioration des processus commerciaux et des bénéfices du commerce électronique. Quant à l'impact des TIC sur les coûts de motivation, on discute de la problématique de l'asymétrie d'information. Nos conclusions suggèrent que la baisse des coûts de coordination est importante. Cependant, l'Internet n'est pas marqué par plus d'asymétrie d'information que le marché traditionnel. Le quatrième chapitre s'intéresse au choix organisationnel en rapport avec l'effet des TIC sur les coûts de transaction. Les limites du choix marché/hiérarchie débouchent sur l'apparition des théories qui tiennent compte de la cœxistence de ces deux choix organisationnels dans de nouvelles formes d'organisation telles que les réseaux. Les principales caractéristiques de ces formes organisationnelles font l'objet des développements du dernier chapitre.
Value Chains in Sub-Saharan Africa
Author: Sören ScholvinPublisher: Springer
ISBN: 3030062066
Category : Business & Economics
Languages : en
Pages : 287
Book Description
Development largely depends on how given places participate in global economic processes.The contributions to this book address various features of the integration of sub-Saharan Africa into the world economy via value chains, so as to explain corresponding challenges and opportunities. The book deals with five issues that have not been covered adequately in scientific debates: first, policies are essential to promote value chains and increase their impact on development; second, value chains are diverse, and the variance between them has major economic and political implications; third, regional value chains appear to constitute a viable alternative to global ones (or, at least, are complementary to them), promising better developmental outcomes for the Global South; fourth, political and socio-economic factors are important considerations for a complete assessment of value chains; fifth, cities and city regions are also crucial objects of study in seeking to achieve a comprehensive assessment of value chains.

World Development Report 1994
Author: Publisher: World Bank Publications
ISBN: 9780195209921
Category : Business & Economics
Languages : en
Pages : 268
Book Description
World Development Report 1994 examines the link between infrastructure and development and explores ways in which developing countries can improve both the provision and the quality of infrastructure services. In recent decades, developing countries have made substantial investments in infrastructure, achieving dramatic gains for households and producers by expanding their access to services such as safe water, sanitation, electric power, telecommunications, and transport. Even more infrastructure investment and expansion are needed in order to extend the reach of services - especially to people living in rural areas and to the poor. But as this report shows, the quantity of investment cannot be the exclusive focus of policy. Improving the quality of infrastructure service also is vital. Both quantity and quality improvements are essential to modernize and diversify production, help countries compete internationally, and accommodate rapid urbanization. The report identifies the basic cause of poor past performance as inadequate institutional incentives for improving the provision of infrastructure. To promote more efficient and responsive service delivery, incentives need to be changed through commercial management, competition, and user involvement. Several trends are helping to improve the performance of infrastructure. First, innovation in technology and in the regulatory management of markets makes more diversity possible in the supply of services. Second, an evaluation of the role of government is leading to a shift from direct government provision of services to increasing private sector provision and recent experience in many countries with public-private partnerships is highlighting new ways to increase efficiency and expand services. Third, increased concern about social and environmental sustainability has heightened public interest in infrastructure design and performance.

Praise for How I Became a Quant "Led by two top-notch quants, Richard R. Lindsey and Barry Schachter, How I Became a Quant details the quirky world of quantitative analysis through stories told by some of today's most successful quants. For anyone who might have thought otherwise, there are engaging personalities behind all that number crunching!" --Ira Kawaller, Kawaller & Co. and the Kawaller Fund "A fun and fascinating read. This book tells the story of how academics, physicists, mathematicians, and other scientists became professional investors managing billions." --David A. Krell, President and CEO, International Securities Exchange "How I Became a Quant should be must reading for all students with a quantitative aptitude. It provides fascinating examples of the dynamic career opportunities potentially open to anyone with the skills and passion for quantitative analysis." --Roy D. Henriksson, Chief Investment Officer, Advanced Portfolio Management "Quants"--those who design and implement mathematical models for the pricing of derivatives, assessment of risk, or prediction of market movements--are the backbone of today's investment industry. As the greater volatility of current financial markets has driven investors to seek shelter from increasing uncertainty, the quant revolution has given people the opportunity to avoid unwanted financial risk by literally trading it away, or more specifically, paying someone else to take on the unwanted risk. How I Became a Quant reveals the faces behind the quant revolution, offering you?the?chance to learn firsthand what it's like to be a?quant today. In this fascinating collection of Wall Street war stories, more than two dozen quants detail their roots, roles, and contributions, explaining what they do and how they do it, as well as outlining the sometimes unexpected paths they have followed from the halls of academia to the front lines of an investment revolution.
Technologies de l'information et de la communication : approches croisées
Author: Alain RalletPublisher: Presses Univ. du Mirail

Category : Electronic commerce
Languages : fr
Pages : 216
Book Description
La place et le rôle des technologies de l'information et de la communication au sein de l'économie et de la société sont devenues des objets centraux d'analyse pour les Sciences humaines et sociales. D'une part, ces technologies accompagnent et sont porteuses de changements, d'autre part, autour d'elles s'organisent des phénomènes d'apprentissage, de coordination, de réorganisation, d'innovation, d'usages... En raison de l'importance des enjeux scientifiques, technologiques et sociaux, il importe de mener une réflexion sur les manières dont les Sciences humaines et sociales peuvent structurer leurs efforts. Le Centre national de la recherche scientifique (CNRS) a pris acte de cette situation en créant, en octobre 2000, le Département " STIC ", et au sein de celui-ci, le GDR " Technologies de l'information et de la communication et société ". Dans cette livraison, Sciences de la Société a laissé la parole à quelques animateurs et participants des journées doctorales organisées à Paris en octobre 2002 par le GDR, en privilégiant le croisement des regards disciplinaires, théoriques et thématiques.

Become a Problem-Solving Crime Analyst
Author: Ronald ClarkePublisher: Routledge
ISBN: 1135898944
Category : Social Science
Languages : en
Pages : 127
Book Description
Crime analysis has become an increasingly important part of policing and crime prevention, and thousands of specialist crime analysts are now employed by police forces worldwide. This is the first book to set out the principles and practice of crime analysis, and is designed to be used both by crime analysts themselves, by those responsible for the training of crime analysts and teaching its principles, and those teaching this subject as part of broader policing and criminal justice courses. The particular focus of this book is on the adoption of a problem solving approach, showing how crime analysis can be used and developed to support a problem oriented policing approach – based on the idea that the police should concentrate on identifying patterns of crime and anticipating crimes rather than just reacting to crimes once they have been committed. In his foreword to this book, Nick Ross, presenter of BBC Crime Watch, argues passionately that crime analysts are 'the new face of policing', and have a crucial part to play in the increasingly sophisticated police response to crime and its approach to crime prevention – 'You are the brains, the expert, the specialist, the boffin.'
