We implement a large-scale field experiment among 50,000 likely unemployed individuals to study the causes and labor supply implications of incomplete UI take-up. Informational letters increased applications and receipt, with effects concentrated among low-wage workers. Rejection rates among treated applicants also increased: this suggests that the letters primarily reduced learning costs rather than improved eligibility beliefs. Randomized messages aimed at reducing free-rider stigma induced more applications, primarily among high-wage job seekers. Although prior work finds that more generous UI slows job finding, our take-up intervention modestly increased reemployment, as work-search requirements hastened job finding among recipients but also screened out applicants who were unwilling or unable to verify their search. We develop and estimate a structural job search model calibrated to the reduced form-experimental results to quantify these frictions and show that lower search-compliance costs yield the largest welfare gains for unemployed workers.", "occurrence_notes":null, "guid":"146130-21898428@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/146130", "building_id":"1005177", "building_name":"North Quad", "campus_maps_id":"553", "room":"4325", "location_name":"North Quad", "has_livestream":0, "cost":"", "tags":["Economics","Public Finance","seminar"], "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":"Public Finance", "group_id":"3553", "website":"" }, { "group_name":"Department of Economics Seminars", "group_id":"3566", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/03\/event_146130_original-1.png", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2026\/03\/event_146130_original-1.png", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/03\/event_146130_original-1.png", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/03\/event_146130_original-1.png", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/03\/event_146130_original-1.png", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2026\/03\/event_146130_original-1.png", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2026\/03\/event_146130_original-1.png", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2026\/03\/event_146130_original-1.png", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2026\/03\/event_146130_original-1.png", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2026\/03\/event_146130_original-1.png", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2026\/03\/event_146130_original-1.png", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/03\/event_146130_original-1.png", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/03\/event_146130_original-1.png", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2026\/03\/event_146130_original-1.png", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2026\/03\/event_146130_original-1.png", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2026\/03\/event_146130_original-1.png" }, "occurrence_count":1, "first_occurrence":21898428 } , "143323-21892902": { "datetime_modified":"20260307T204322", "datetime_start":"20260330T160000", "datetime_end":"20260330T170000", "has_end_time":1, "date_start":"2026-03-30", "date_end":"2026-03-30", "time_start":"16:00:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"GLNT: How you think on a function defined on 0,1,\u2026,N-1?", "occurrence_title":"", "combined_title":"GLNT: How you think on a function defined on 0,1,\u2026,N-1?: Shamgar Gurevich (University of Wisconsin--Madison)", "event_subtitle":"Shamgar Gurevich (University of Wisconsin--Madison)", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Abstract: Between thousand to million times per day, your cellphone calculates the Fourier Transform (FT) of certain complex valued functions defined on 0,1,\u2026,N-1, with N large (order of magnitude of thousands and more). \nThe calculation is done using the Fast Fourier Transform (FFT) - discovered by Cooley--Tukey in 1965 and by Gauss in 1805. \n\nIn the lecture I want to advertise a beautiful way\u2014due to Auslander-Tolimieri\u2014to obtain the FFT as a natural consequence of an answer to the following:\n\nQuestion: How to think on the space of functions on the set 0,1,\u2026,N-1?
