SUMMARY:Séminaire GRETHA: Selma Boussetta
DESCRIPTION:Agenda > Tous les événements\nSelma Boussetta\nGREThA\, université de Bordeaux \n\n \n« The role of pre-opening mechanisms in fragmented markets »\nco-écrit avec  L. Lescourret et S. Moinas\nAbstract: To facilitate price discovery\, Euronext Paris has always relied on a pre-opening phase. Fast trading\, competition from alternative platforms and poor volume at the open (2%) questions the role of these non-trading sessions. Using a unique dataset of stocks cross-traded on Euronext\, BATS and Chi-X\, we investigate the pre-opening behavior of tradersbased on their speed and type (traders\, brokers or market-makers). We find that the pre-opening activity of fast traders is positively related to price discovery across all platforms. Slow brokers\, submitting orders very early\, contribute to price discovery but only on Euronext. Using an exogenous technological glitch that delayed the pre-opening\, we show that the delay increased (reduced) the presence of slow brokers (fast traders). Price discovery on Euronext significantly decreased on the day of the glitch.

SUMMARY:Séminaire GREThA: Léa Tardieu
DESCRIPTION:Agenda > Tous les événements\nLéa Tardieu\nCIRED\, AgroParisTech\, Cirad\, CNRS\, EHESS\, Ecole des Ponts ParisTech\, Université Paris-Saclay\n \n« Mapping forest attractiveness for outdoor recreation: Spatial tools for management planning »\n The concept of ecosystem services (ESs) remains underused in supporting practical decisions in conservation/development plans and programmes. One of the most important knowledge gaps for a better consideration is related to ESs spatial assessment and mapping. I will present the results of three studies related to this issue. In the first study\, we develop a methodology to assess and map one of the major ES in a French regional park: recreational attractiveness. Because the area under study is a large territory\, primary valuation techniques would have been difficult to apply. Thus\, we characterise the recreation attractiveness function on a part of the study area\, that is further transferred in the entire zone. Predictions are based on a lancasterian function of biophysical attributes and a travel cost model. To the best of our knowledge\, this study constitutes one of the first attempts at function benefit transfer based on a travel cost model. The results call for a better accounting of site characteristics in travel cost methods that are principally focused on individual characteristics. From a policy guidance perspective\, we show that spatial statistical analysis of the created indicator helps in evaluating the management planning strategy of the park. A test of the application of the methodology is now held\, in a second study\, at the national scale based on three waves of a recent national surveys conducted in France. Finally\, a third study provide an analysis of the impact of using perceived forests characteristics by visitors in the models versus using observed data calculated with geographical information systems.

SUMMARY:Séminaire GREThA: Denis Cogneau
DESCRIPTION:Agenda > Tous les événements\n Denis Cogneau\n Paris School of Economics (PSE)\, Ecole des Hautes Etudes en Sciences Sociales (EHESS)\, Institut de Recherche pour le Développement (IRD)\n \n“Fiscal Capacity and Dualism in Colonial States: The French Empire 1830-1962”\n(with Yannick Dupraz & Sandrine Mesplé-Somps) \nAbstract: A novel data collection provides comparative evidence on colonial states of the “second” French colonial empire\, from their foundation to their devolution in the 1960s. Colonial states were neither omnipotent Leviathans nor casual night watchmen. On the one hand\, we emphasize the extractive efficiency and capacity of adaptation of colonial states to different socioeconomic contexts and varying historical conditions. On the other hand\, we put forward dualism as their main common feature and legacy. Colonial public expenditure was biased towards the needs of French settlers and capitalists. It was also costly\, as high wages had to be paid to expatriated civil servants. \n
