The Impact of External Shocks in East Asia: Lessons from a Structural VAR Model with Block Exogeneity

In this paper, we examine the relative importance of external shocks in domestic fluctuations of East Asian countries and check if these shocks lead to asymmetric or symmetric reactions between the considered economies. To this end, we estimate, over the period 1990.1-2010.4, a structural VAR model with block exogeneity (SVARX model) relying on a comprehensive set of external shocks. We firstly document a rising impact of these external shocks on domestic variables since the mid 1990s. Finally, real oil price and U.S. GDP shocks have a significant impact on domestic activity and lead to more symmetric responses, compared to U.S. monetary shock and MSCI Index financial shocks.external shocks, East Asia, SVARX model.

Des observations à la construction d'un modèle de simulation de la dynamique urbaine : une approche inductive

International audienceThrough this paper, we chose to present a modelling concept the aim of which is the simulation of the intra-urban location dynamics. This concept includes some characteristics which relate it to the synergetic models as well as to the micro-simulation ones. In the first part of this paper, we describe and examine the modelling concept to focus in a second part on a more detailed presentation of one aspect of the model concerning the measure of the attractiveness of the neighbourhoods of a town.Dans cet article, nous avons choisi de présenter un concept de modélisation dont le but est la simulation de la dynamique des localisations d'activités en milieu intra-urbain. De par ses caractéristiques, ce concept se rattache tant aux modèles synergétiques qu'à ceux de micro-simulation. Dans la première partie de cet article, nous décrivons et commentons le concept de modélisation proposé pour, dans une seconde partie, s'attacher plus particulièrement à la présentation détaillée d'un aspect du modèle, à savoir la mesure de l'attractivité des quartiers d'une ville

Economic Trends in Enterprise Search Solutions

Enterprise search technology retrieves information within organizations. This data can be proprietary and public, its access to it may be restricted or not. Enterprise search solutions render business processes more efficient particularly in data-intensive companies. This technology is key to increasing the competitiveness of the digital economy; thus it constitutes a strategic market for the European Union. The Enterprise Search Solution (ESS) market was worth close to one billion USD in 2008 and is expected to grow quicker than the overall market for information and knowledge management systems. Optimistic market forecasts expect market size to exceed 1,200 million USD by the end of 2010. Other market analyses see the growth rate slowing down and stabilizing at around 10% a year in 2010. Even in the least favourable case, enterprise search remains an attractive market, particularly because of the opportunities expected to arise from the convergence of ESS and Information Systems. This report looks at the demand and supply side of ESS and provides data about the market. It presents the evolution of market dynamics over the past decade and describes the current situation. Our main thesis is that ESS is currently placed at the point where two established markets, namely web search and the management of information systems, overlap. The report offers evidence that these two markets are converging and discusses the role of the different stakeholders (providers of web search engines, enterprise resource management tools, pure enterprise search tools, etc.) in this changing context.JRC.DDG.J.4-Information Societ

Relation client et réseaux sociaux : postures et images du client

International audienceThis article analyze one or several postures of the customer in the relation that he maintains with the company through the various canals, in particular, the social networks. By posture, it is necessary to understand the self-presentation, in the management of the discourses and the uses. This posture is shaped by the company but also by the technological environment; it is the result of an interactive process, it is co-built
