Fiscal Harmonization and Portfolio Choice
In this paper, we consider a two-country model based on Svensson (1989) in order to analyze how fiscal harmonization impacts on economic growth and welfare through its effects on agents portfolio decisions in an uncertain world. We derive the conditions under which fiscal harmonization proves to be welfare enhancing and analyse how the set of initial tax rates leading to a welfare improving harmonization is affected by uncertainty and assets returns correlation. In particular, the results obtained suggest that the probability for tax harmonization to be welfare improving is first increasing and then decreasing with uncertainty while it monotonically decreases with the correlation between the assets returns shocks.fiscal harmonization; growth; uncertainty
Chinese Import Competition and Skill Upgrading in European Textiles.
In this paper we study the effect of import competition from China on the Belgian textiles sector. Our analysis comprises both trade data and firm-level data. We study the evolution of the unit values in textiles exported from China into the EU versus textiles exported from Belgium to the rest of the EU over the past ten years. We clearly find evidence of a widening price gap between Chinese and Belgian textiles export prices. Chinese textiles seem to become relatively cheaper over time. These findings are in line with Schott (2004; 2007) who argues that capital abundant countries in the US and Europe use their endowment advantage to produce product varieties that are superior in quality compared to labour intensive countries like China. Next we use firm-level data on Belgian textiles firms in search of evidence of quality and skill upgrading in Belgian textiles exports. We study the evolution of firm-level variables such as R&D outlays, the proportion of skilled and unskilled labour used in production and capital intensity. Both Chinaâs entry into the WTO and the end of the Multi- Fibre Agreement significantly seem to cause important shifts in firm level production processes. A very robust result that emerges from the analysis is the one of skill upgrading. While over the past ten years total employment in the Belgian textiles sector has substantially decreased, the ratio of skilled versus unskilled workers has gone up significantly. The evidence is indicative that the Belgian textile sector has been undergoing substantial changes. It is becoming smaller but at the same time seems to be responding to the competition from a low-wage country like China by increasing the skill-content of its products and moving up the quality ladder.textiles; import competition;
Skill-upgrading in European textiles resulting from trade with China: firm-level evidence.
In this paper we study the effect of import competition from China on the Belgian textiles sector. Our analysis comprises both trade data and firm-level data.

Next we use firm-level data on Belgian textiles firms in search of evidence of quality and skill upgrading in Belgian textiles exports. We study the evolution of firm-level variables such as R&D outlays, the proportion of skilled and unskilled labour used in production and capital intensity.

Trait-anxiety dependence of movement time performance in a bimodal choice task in subjects exposed to moderate anxiogenic conditions
International audienceRecent studies have provided insight into the interdependence between state-anxiety, trait-anxiety and motor performances. In the present study, we investigated in very low trait-anxiety (VLTA) and normal trait-anxiety (NTA) subjects, the effects of moderate state-anxiety induced by the video-recorded Stroop color word interference test, on reaction time and movement time in bimodal choice response time task providing either visual or auditory modality. We found that in anxiogenic condition, movement time performances were improved in visual modality in NTA subjects, and in auditory modality in VLTA subjects. Our results show that depending on their trait-anxiety level, individuals exposed to anxiogenic condition would allocate attentional resources towards a specific relevant modality. Such attentional resources would influence movement time, but not reaction time
Education Funding and Regional Convergence
The aim of this paper is to discuss the process of regional convergence within the framework of an overlapping generations model in which the engine of growth is the accumulation of human capital. In particular, we consider different education funding systems and compare their performance in terms of growth rates and pace of convergence between two heterogeneous regions. The analysis suggests that the choice of a particular education system incorporates a possible trade-off between long run growth rate and short run convergence. In such choice, the initial capital stock and the extent of regional human capital discrepancy appear as central variables.Altruism; education; growth; convergence; capital mobility
Rhomolo: A Dynamic Spatial General Equilibrium Model for Assessing the Impact of Cohesion Policy
The present paper presents the newly developed dynamic spatial general equilibrium model of European Commission - RHOMOLO, in which the interplay of agglomeration and dispersion forces can be analysed in a novel and theoretically consistent way. A particular attention is paid to income, migration flows and capital movements within and between regions that are generated by the stimulus to the regions. This will allow an assessment of the feedback to the Member States and regions and the possibility that in the longer run they will all benefit from the additional growth that is generated. The paper analyses the implications of different assumptions on capital and labour mobility within and between Member States on the spatial equilibrium in terms of income and employment. In doing so, it sheds new light on how the success of cohesion policy can be measured.JRC.J.2-Knowledge for Growt

We focus on the details of the experimental set-up which is newly, specially designed for this study in the preliminary step of the project. The four French academic teams and two PhD thesis are involved in the ForDiMHyS project on the period 2000-2004. The financial support is given by the five French Partners. The project consists of two-step programs; firstly the data acquisition from the laboratory experimental set-up and secondly simulation of methane production from methane hydrate fields
Plutonium in the environment: key factors related to impact assessment in case of an accidental atmospheric release
International audienceThis paper deals with plutonium and key factors related to impact assessment. It is based on recent work performed by CEA which summarize the main features of plutonium behaviour from sources inside installations to the environment and man, and to report current knowledge on the different parameters used in models for environmental and radiological impact assessment. These key factors are illustrated through a case study based on an accidental atmospheric release of Pu in a nuclear facility
Pesticide exposure of pregnant women in Guadeloupe: Ability of a food frequency questionnaire to estimate blood concentration of chlordecone
Context Chlordecone, an environmentally persistent organochlorine insecticide used intensively in banana culture in the French West Indies until 1993, has permanently polluted soils and contaminated foodstuffs. Consumption of contaminated food is the main source of exposure nowadays. We sought to identify main contributors to blood chlordecone concentration (BCC) and to validate an exposure indicator based on food intakes.Material and methods We used a food frequency questionnaire (FFQ) completed by a sample of 194 pregnant women to estimate their dietary exposure to chlordecone and compared it to blood levels. In a first approach, chlordecone daily intake was estimated as the product of daily eaten quantity of 214 foodstuffs, multiplied by their chlordecone content, and summed over all items. We then predicted individual blood chlordecone concentration with empirical weight regression models based on frequency of food consumption, and without contamination data.Results Among the 191 subjects who had BCC determination, 146 (76%) had detectable values and mean BCC was 0.86†ng/mL (range < LOD-13.2). Mean per capita dietary intake of chlordecone was estimated at 3.3†[mu]g/day (range: 0.1-22.2). Blood chlordecone levels were significantly correlated with food exposure predicted from the empirical weight models (r=0.47, p<0.0001) and, to a lesser extent, with chlordecone intake estimated from food consumption and food contamination data (r=0.20, p=0.007). Main contributors to chlordecone exposure included seafood, root vegetables, and Cucurbitaceous.Conclusion These results show that the Timoun FFQ provides valid estimates of chlordecone exposure. Estimates from empirical weight models correlated better with blood levels of chlordecone than did estimates from the dietary intake assessment
