SUMMARY:Cerna Lunch Seminar with Tove Karlsson (Stockholm School of Economics)
DESCRIPTION:We have the pleasure to announce Tove Karlsson (Stockholm School of Economics) as the next speaker in our CERNA Lunch Seminar series. The seminar will take place on Tuesday 08/03/2022 at 12:30 am in Salle Chevalier. The log-in information for the live stream on Zoom will also be provided in due course.\n \nTove will talk about: \nEvaluating the Production Approach  \nto Estimate Markups \n  \n How reliable are markups estimated with the production approach? The production approach derives a measure of firm-level markups from the firm’s cost minimization problem\, which can be estimated from financial data on firms. However\, concerns have been raised about the distribution of estimated markups and their information content on true markups. This paper examines this concern empirically. While the distribution of true markups is notoriously hard to estimate\, it is a stylized fact that markups are higher on more concentrated markets. Given this relationship between true markups and market structure\, I test whether estimated markups are higher on more concentrated markets. Using panel data on the complete population of Swedish firms across four sectors\, 251 local markets\, and 20 years\, I find that markup estimates generally follow the expected pattern. My results\, thus\, support the reliability of the production approach.

SUMMARY:Cerna Research Seminar will welcome Chloé Le Coq (Paris 2\, CRED)
DESCRIPTION:We have the pleasure to announce Chloé Le Coq (Paris 2\, CRED) as the next speaker in our CERNA Research Seminar series. The seminar will take place on Wednesday 9/3/2022 at 16:00 in Salle Vendome\, Mines ParisTech. The log-in information for the live stream on Zoom will also be provided in due course.\n \nChloé will talk about: \n  \n Cartel birth and death dynamics: empirical evidence \nThis paper examines how the legal and macroeconomic environments impact cartel births and deaths. We exploit the gradual tightening of the competition law to study how cartels react to increased competition pressure. To avoid the inherent sample selection bias in prosecuted cartel studies\, we use a unique dataset covering the population of Swedish legal cartels registered between 1947 and 1993. We estimate both a count model that considers the registered cartels and a hidden Markov model\, which accounts for the varying efficiency of the register in observing collusion. These two complementary approaches allow us to characterize the observed\, and potentially hidden\, dynamics of cartels. We find that strengthening the competition law has some deterrent effect. However\, as the competition law becomes more severe (i.e.\, the cartel ban’s threat becomes credible)\, cartels continue forming but are undercovered. We also show that volatility and high-interest rates hinder collusion (lowering births and increasing deaths).  \n  \nTo register for the seminar

In autumn 2012\, she began a research project on life after the triple catastrophe that look place in the Northeast Japan (a tsunami\, an earthquake\, and a nuclear accident). On this question\, she contributed to the creation of a hybrid collective\, Call It Anything\, headed by F93\, regrouping several social science researchers\, artists\, and video makers for experiments intersecting with the themes of trouble\, damaged territory\, radioactivity\, and the restoration of the existing \nThe research seminar « Change of scale – Change of nature »\nThe generalist and interdisciplinary seminar “Change of scale – Change of nature” is organized by the CSI and the Eco-anthropology laboratory of the Natural History Museum by Léo MARIANI (MNHN\, Eco-anthropology)\, Julien BLANC (MNHN\, Eco-anthropology)\, Brice LAURENT (CNRS\, CSI) and Jean GOIZAUSKAS (Mines Paris\, CSI).

The succession of environmental\, social and governance (ESG) scandals\, whose media coverage has been widely amplified by social networks\, has contributed to converting some of these issues into extra-financial risks. This awareness of this extra-financial risk (El Ghoul et al.\, SRI or towards a so-called sustainable finance. \nThe “mainstream” in finance now consists of combining financial and ESG criteria. In the context of the French market alone\, more than a third of the assets under management\, i.e. nearly 1\,000 billion euros of assets\, incorporate ESG criteria to a greater or lesser extent\, and more than a tenth correspond to strict SRI management. We have thus truly emerged from the “niche” and the phenomenon of strong expansion envisaged a decade ago (Crifo and Mottis\, 2011) is well underway.

SUMMARY:i3 Interdisciplinary Study Day: Why\, with whom and how to design?
DESCRIPTION:The imperative of co-design in architectural and urban projects is becoming increasingly strong among institutional players and professionals in the housing and construction sector.

This stakeholder is traditionally presented by the promoters of\nThis stakeholder is traditionally presented by the promoters of urban co-design both as a person who requires information on the projects and as a figure embodying the uses of the projects\, knowledge of which is essential for the development of suitable projects.\nHowever\, the application of this type of approach in the building and development sector confronts the actors with a certain number of problems concerning the methodology to adopt in order to target and encourage the participation of the adapted public on the one hand\, and to articulate the co-design process with the ecosystem of actors\, practices and standards of the sector on the other. \n  \nThe study day is divided into three parts:\n– The figure of the citizen-user\n– The methodology\n– Decision-making\nIt will be composed of presentations and round tables bringing together researchers from various disciplines (design\, sociology\, ergonomics\, management sciences\, etc.) and professionals from different levels of design (public authorities\, innovation management\, designers\, architects\, urban planners\, etc.) and aimed at both academic and non-academic audiences. \nDownload the Programme and information about the event      \n
