As in many industrial settings, we do not observe costs. Instead, we infer them by modeling the turbine procurement process, and estimate the model on the near-universe of global commercial wind farms built from 2000 to 2019. We find that while commonly reported measures of price per unit of capacity fell by 30 percent during this time, latent quality-adjusted costs fell by over 75 percent. Underpinning these cost declines, we estimate substantial learning-by-doing. A doubling of manufacturing experience reduces manufacturing costs by 26 to 29 percent. Though inter-firm spillovers per unit are relatively small, in aggregate, they rationalize a significant portion of the cost reductions over time.", "occurrence_notes":null, "guid":"151827-21912235@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/151827", "building_id":"1005177", "building_name":"North Quad", "campus_maps_id":"553", "room":"4325", "location_name":"North Quad", "has_livestream":0, "cost":"", "tags":["seminar","Environment","Energy","Economics"], "website":"http:\/\/www.lsa.umich.edu\/econ", "sponsors":[ { "group_name":"Department of Economics", "group_id":"3302", "website":"http:\/\/www.lsa.umich.edu\/econ" }, { "group_name":"Applied Microeconomics\/Industrial Organization", "group_id":"3545", "website":"" }, { "group_name":"Energy & Environmental Economics", "group_id":"3547", "website":"" }, { "group_name":"Department of Economics Seminars", "group_id":"3566", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/10\/event_151827_original-2.jpg", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_thumb\/media\/attachments\/2026\/10\/event_151827_original-2.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/10\/event_151827_original-2.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/10\/event_151827_original-2.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/10\/event_151827_original-2.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb\/media\/attachments\/2026\/10\/event_151827_original-2.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb_square\/media\/attachments\/2026\/10\/event_151827_original-2.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large\/media\/attachments\/2026\/10\/event_151827_original-2.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large_lightbox\/media\/attachments\/2026\/10\/event_151827_original-2.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large_crop\/media\/attachments\/2026\/10\/event_151827_original-2.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_list\/media\/attachments\/2026\/10\/event_151827_original-2.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/10\/event_151827_original-2.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/10\/event_151827_original-2.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_grid_2x\/media\/attachments\/2026\/10\/event_151827_original-2.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_large\/media\/attachments\/2026\/10\/event_151827_original-2.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_thumb\/media\/attachments\/2026\/10\/event_151827_original-2.jpg" }, "occurrence_count":1, "first_occurrence":21912235 } , "150692-21909932": { "datetime_modified":"20261005T090606", "datetime_start":"20261014T100000", "datetime_end":"20261014T170000", "has_end_time":1, "date_start":"2026-10-14", "date_end":"2026-10-14", "time_start":"10:00:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"CMENAS 65th Anniversary: Celebrate the Legacy, Scholarship, & Future of MENA Studies", "occurrence_title":"", "combined_title":"CMENAS 65th Anniversary: Celebrate the Legacy, Scholarship, & Future of MENA Studies: Keynote by Aaron David Miller, Senior Fellow, Carnegie Endowment for International Peace", "event_subtitle":"Keynote by Aaron David Miller, Senior Fellow, Carnegie Endowment for International Peace", "event_type":"Conference \/ Symposium", "event_type_id":"5", "description":"10:30\u201311: Arrival & Registration\n\n11:00\u201311:10: Director Welcome Remarks by CMENAS Director Jay Crisostomo, George G.
