SUMMARY:CERNA Research Seminar will welcome Daniel Herrera (Dauphine)
DESCRIPTION:The effects of banning loss-leader pricing in grocery retailing markets \n(joint with Jorge Florez\, Banco de la Republica) \nHalf of the states of the U.S. ban loss-leader pricing because it is considered predatory. Recent theoretical evidence challenges this view\, suggesting that loss-leading may arise as a result of a discrimination of consumers with different shopping costs. We examine the effects of banning loss-leader pricing in grocery retailing markets on supermarket pricing. To this end\, we use scanner data on supermarket sales in the United States and carry out two empirical exercises. First\, we exploit an exogenous shock in the below-cost selling law in Wisconsin between 2009 and 2010 to identify the causal effect on prices on milk. Our results suggest that prices increase as a result of the ban of below-cost selling. Second\, we estimate a structural model of demand and supply of multiple products allowing for complementarities across products. The main challenge that is common in the estimation of demand models in this type of setting is a high-dimensional choice set. We propose a novel solution to this challenge and provide evidence of its effectiveness based on Monte Carlo simulations. Using our demand estimation approach\, we find negative margins consistent with competitive cross-subsidization across products within a retailer chain. Our counterfactual results suggest that banning below-cost pricing rises equilibrium prices.  \n

SUMMARY:The seminar “Digital environmental policies” will welcome  Djilali Taïar (CDEP\, Université d’Artois)
DESCRIPTION:The seminar “Digital environmental policies” will welcome \n  \nDjilali Taïar (CDEP\, Université d’Artois) \n  \nLa régulation environnementale du numérique en France \nEnvironmental regulation of digital technology in France \n \n  \nSummary: As of the end of 2021\, two laws have given regulatory authorities (Arcep and Arcom) the mandate of supporting digital actors in adopting more environmentally friendly practices. Despite the introduction of a binding environmental data collection regime\, reducing the sector’s footprint still depends on the goodwill of private actors. Nevertheless\, the regulatory authorities’ role should be strengthened to regulate their practices. This presentation aims to establish the current status of the new legal regime applicable to digital professionals\, while looking at whether the means implemented are up to the expressly sought-after objective: reducing the environmental footprint of digital technology. \n  \n\n\n\nDate: December 15\, 2022\, 2:00 pm to 4:00 pm \nThe seminar will be held by videoconference. Participation is upon registration only. \nLearn more about the seminar’s objectives and program \nPhoto source: Djilali Taïar\, Eloquentia France\, 2020. \n\n\n\n\n\n\n         \n\n \n\n\n \n\n \n         \n\n\n\n\n \n\n

SUMMARY:Cerna Lunch Seminar will welcome Felix Poege (Postdoctoral Associate at the Technology & Policy Research Initiative at Boston University)
DESCRIPTION:The  16th December at 12h00 in Salle Vendome\, we will have a lunch seminar out of the usual schedule by Felix Poege (Postdoctoral Associate at the Technology & Policy Research Initiative at Boston University). You can find his profile here: https://www.felixpoege.eu/ \nFelix will present his job market paper about “Competition and Innovation: The Breakup of IG Farben” \nAbstract The relationship between competition and innovation is difficult to disentangle\, as exogenous variation in market structure is rare. The 1952 breakup of Germany’s leading chemical company\, IG Farben\, represents such a disruption. After the Second World War\, the Allies occupying Germany imposed the breakup because of IG Farben’s importance for the German war economy instead of standard antitrust concerns. In technology areas where the breakup reduced concentration\, patenting increased strongly\, driven by domestic firms unrelated to IG Farben. An analysis of patent texts shows that an increased propensity to patent does not drive the effect. Descriptively\, IG Farben’s successors increased their patenting activities as well\, and their patenting specialized relative to the pre-breakup period. The results are consistent with a breakup-induced innovation increase by the IG Farben successors\, which then spilled over to the wider chemical industry. \nLink to full paper: https://www.felixpoege.eu/workingpaper/#competition-and-innovation-breaking-ig-farben \nBlog summary: on https://www.promarket.org/2022/10/05/new-research-shows-the-breakup-of-ig-farben-increased-innovation/ \nAks the link \n  \n
