L'impact de l'information sur le résultat d'une vente aux enchères expérimentale de vin
2005
This paper reports the results of an experimental wine auction. Participants of the experiment were randomly assigned to three rooms. In each room four wines had to be evaluated, but the level of information to which participants had access differed across rooms. After the evaluations, the wines were sold sequentially, by four separate Vickrey auctions with secret reservation prices. We fi nd that certain socio-economic characteristics such as gender, income and consumption habits, have a signifi cant impact on the willingness to pay for wine, while others such as age and nationality, do not. We also fi nd that once individuals have read the label characteristics and extracts from wine guid…
The editorial function of the territorial intelligence systems
2006
This communication makes an updating of our thinking about the editorial function of the systems of territorial intelligence. Computer science and information systems aim at increasing the communication between the human beings. A territorial intelligence system is an instrument at the service of the actors who ambition to control the development the equitable and sustainable development of their territory. Since the irruption of data processing, we led research activities to design friendly software, then to model the structure of a territorial information system that is at the service of a network of territorial actors, and more recently to integrate the data analysis functions. They led …

La gratuité des musées et des monuments : qu’en pensent les publics en France ?
2015
The question of free admission has generated numerous debates, highlighting various viewpoints of professionals involved in Culture, effects on the measured volumes of attendance and on the management of museums and monuments. One question has been left aside: that of the reception of free admissionmeasures by the destined audiences. The analysis of the representations of these measures, which are found to be multiple, contradictory and not very congruent with the ideals put forth by the institutions themselves, shows the subtlety of the complex interactions between the tariff amount, the comprehension of a cultural policy, impact on the representations of museums and monuments and frequent…
Welfare, Home Market Effects, and Horizontal Foreign Direct Investment
2005
We investigate the spatial distribution and organization of an imperfectly competitive industry when firms may choose to operate more than a single production unit. Focusing on a short-run setting with a fixed mass of firms, we fully characterize the spatial equilibria analytically. Comparing the equilibrium and the first-best, we show that both organizational and spatial inefficiencies may arise. In particular, when fixed costs are low enough the market outcome may well lead to overinvestment and, therefore, to too many multinationals operating from a social point of view. Furthermore, once multinationals are taken into account, the market outcome may well lead too little agglomeration.
Intangible capital and business productivity in the hotel industry
2019
Intangible capital is a key factor of productivity growth. This paper analyses how the internal intangible capital of the company and external intangible capital influence its productivity. This contribution focuses on the hotel industry since it is a key industry of the Spanish economy, such that any increase in its productivity has an impact on the entire economy. Both, the intangible capital of the company and that of the region in which the company is located are considered as determinants of productivity. Likewise, the importance of other agglomeration economies in the productivity of hotel companies is taken into account. A model estimates firm level determinants of productivity, cont…
Iron oxide-based magnetic photocatalysts: Recent developments, challenges, and environmental applications
2021
Abstract Magnetic separation of the solid photocatalyst from the reacting suspension has received great interest in recent research because it offers a suitable way for removing and recycling the heterogeneous photocatalytic material particles preventing the agglomeration and sedimentation during and after their use. The use of iron oxides such as heterogeneous photocatalysts is an appropriate choice to obtain a suitable photocatalyst easily separable from the fluid. This chapter presents a detailed investigation of iron oxide-based magnetic photocatalysts (IOMPs). We will discuss the required conditions for the synthesis of these photocatalysts, followed by their applications for the remov…

Satisfacción laboral en los países pobres: el caso de los docentes malgaches
2015
Utilizando informaciones inéditas recopiladas en el marco de un amplio programa de mejora de la gestión del sistema educativo, este articulo analiza los niveles de satisfacción de los docentes de educación primaria en Madagascar. En base a la estimación de modelos multinivel, se identifican como principales factores de insatisfacción los bajos niveles salariales y las dificultades en el cobro, los elevados ratios alumno-profesor, la precariedad en el empleo, la carencia de formación continua y la falta de infraestructuras básicas y material docente. Las tareas de control realizadas por el director también afectan negativamente a la satisfacción, lo que apunta a que, en las escuelas malgache…
COMMUTING PATTERNS IN RIGA AGGLOMERATION: EVIDENCE FROM A SURVEY ANALYSIS OF YOUTH
2021
In the last ten years the evident changes of settlement patterns through suburban growth near to capital city of Latvia occurred. Increase of distance between home and routine activity places as well as changes of public transport and rapid increase of car ownership initiated significant changes in commuting patterns of inhabitants living outside of Riga. Although the commuting from suburban area to Riga is recently broadly studied, however these researches focused primarily on able-bodied population leaving behind school-age children and young people. The aim of this study is to analyse commuting patterns of young people aged 12 to 17 moving from outskirts of Riga to school located in Riga…
