SUMMARY:Thibaud HENNET (CREST) "The macroeconomic transmission of electricity supply and demand shocks"
DESCRIPTION:[vc_row][vc_column][vc_column_text]Macro seminar\nTime : 12h15 – 13h30 \nDate : 13th  April 2026 \nSalle 3001 \nThibaud HENNET (CREST) “The macroeconomic transmission of electricity supply and demand shocks” \nAbstract: : The 2021 energy crisis reignited inflation in Europe and exposed the fragility of its energy supply\, with electricity prices tripling or quadrupling in several countries within a year. Using detailed supply and demand curve data from the Spanish electricity market\, this paper identifies exogenous natural shocks and shows that conventional supply and demand shifters often contain cross-components that hinder identification. I construct synthetic instruments that outperform standard approaches in estimating price elasticities. These identified shocks are then employed in a proxy-SVAR to assess their transmission to inflation and industrial production. Finally\, two applications are examined : the Iberian exception\, which reduced inflation by about 3 percentage points\, and a counterfactual increase in wind capacity\, which points to amplified macroeconomic fluctuations with greater renewable integration \nOrganizer : Suzanne BELLUE \n

SUMMARY:Julien DUBOIS (CREST) "Phasing Out Fossil Fuels: A Theory to Disentangle Transition Forces"
DESCRIPTION:[vc_row][vc_column][vc_column_text]Macro seminar\nTime : 12h15 – 13h30 \nDate : 13th  April 2026 \nSalle 3001 \nJulien DUBOIS (CREST) “Phasing Out Fossil Fuels: A Theory to Disentangle Transition Forces” \nAbstract: Can growth and emission use be decoupled\, and if so\, through which mechanism? This paper develops a framework in which three forces drive the energy transition: (i) capital installation\, where investment in cleaner vintages reduces emission intensity; (ii) Directed Disembodied Technical Change (DDTC)\, where R&D shifts the production frontier; and (iii) post-installation adjustment\, where already-installed capital adapts its emission intensity over time. The third force is typically omitted from the literature\, which treats capital as either fully rigid or fully flexible after installation. I capture it explicitly through a parameter θ ∈ [0\,1] measuring the intensity of post-installation adjustment frictions\, and show this is of first-order importance\, both qualitatively and quantitatively. Qualitatively\, θ governs how the three forces interact: in particular\, DDTC affects capital vintages heterogeneously and can perversely delay the scrapping of emission-intensive machines. Quantitatively\, Bayesian estimation on U.S. data (1949-2024) shows that the assumed value of θ alone drives the estimated elasticity of substitution between capital and emissions from near zero to near unity.\n \nOrganizer : Suzanne BELLULE  \n

SUMMARY:Hugo LAVENANT (Bocconi University)- Masked diffusions: how to choose an optimal schedule and how much is gained ?
DESCRIPTION:Statistical Seminar: Every Monday at 2:00 pm.\nTime: 2:00 pm – 3:00 pm\nDate: 13th April\nPlace: 3001 \n  \nHugo LAVENANT (Bocconi University)- Masked diffusions: how to choose an optimal schedule and how much is gained ? \n \n  \n Abstract:  \n  \nWe look at the computational error made in the generation phase of Masked Diffusion Models\, which were recently proposed for generative modelling of discrete data. These models make approximations of conditional dependence to speed up generation of new samples at the price of some bias in the sampling distribution. We explain how these models can be simply described once you do not try to make a parallel with continuous diffusion models. From this elementary description\, we study the resulting computation-vs-accuracy trade-off\, providing general error bounds in relative entropy\, and we investigate the gains obtained by using non-constant schedule sizes. \nThis is joint work with Giacomo Zanella. \n  \nOrganizers: \nAnna KORBA (CREST)\, Vincent DIVOL (CREST) \, Jaouad MOURTADA (CREST) \nSponsors:\nCREST-CMAP \n
