SUMMARY:[Environment session]  - Pierre COURTOIS (CEE-M) - "A Tale of Two Diversities" joint with C. Figuieres and C. Mulier
DESCRIPTION:\nThe Microeconomics Seminar: Friday from 12 pm to 13:15 pm. \nTime: 12:00 pm – 1:15 pm\nDate: 15th of June 2018\nPlace: Room 3001. \nPierre COURTOIS (CEE-M) – “A Tale of Two Diversities” with C. Figuieres and C. Mulier \nAbstract: Efficient biodiversity management strategies aim to allocate conservation efforts in order to maximize diversity in ecological systems. Toward this end\, dening a diversity criterion is an important but challenging task\, as several di erent indices can be used as biodiversity measures. This paper elicits and compares two in situ criteria for biodiversity conservation based on indices stemming from different disciplines: Weitzman’s index in economics and Rao’s index in ecology. These indices combine in di erent ways\, information about measures of (1) species’ probability and (2) species’ dissimilarity. As an important step toward in situ protection criteria\, to these elements we add information about (3) the ecological interactions between species. Considering a simple three-species ecosystem\, we show that criterion choice has palpable policy implications\, as it can sometimes lead to diverging management recommendations. We disentangle the role played by elements (1)\, (2) and (3) in the ranking outcomes\, which allows us to highlight some specicities of the in situ criteria. An important result is that\, other things equal\, Weitzman’s in situ ranking tends to favor “robust” species\, while Rao’s in situ ranking generally gives priority to “fragile” species. \n\nOrganizers: \n\nMarie-Laure Allain\, Pierre Boyer\, Laurent Linnemer  &  Morgane Cure (CREST) \nSponsors:\nCREST \nFood is provided. \n\n\n
