This paper analyzes the extent to which these differences reflect causal effects of marriage versus selection. We develop a dynamic Roy model that allows for selection into and out of marriage, with cognitive skill evolving according to a dynamic latent factor model. A long panel of marriage decisions permits identification of unobserved heterogeneity jointly affecting both marriage and skill development. Model estimates indicate that marriage improves skill development. A decomposition analysis suggests that differences in the technology of skill formation between the married and single states explains 30% of the skill difference between children growing up in two-parent and one-parent households while income differences explain 16%.", "occurrence_notes":null, "guid":"143695-21893656@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/143695", "building_id":"1005177", "building_name":"North Quad", "campus_maps_id":"553", "room":"4325", "location_name":"North Quad", "has_livestream":0, "cost":"", "tags":["Economics","Labor","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":"ISR-Zwerdling Seminar in Labor Economics", "group_id":"3551", "website":"" }, { "group_name":"Department of Economics Seminars", "group_id":"3566", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/01\/event_143695_original-1.png", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2026\/01\/event_143695_original-1.png", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/01\/event_143695_original-1.png", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/01\/event_143695_original-1.png", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/01\/event_143695_original-1.png", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2026\/01\/event_143695_original-1.png", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2026\/01\/event_143695_original-1.png", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2026\/01\/event_143695_original-1.png", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2026\/01\/event_143695_original-1.png", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2026\/01\/event_143695_original-1.png", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2026\/01\/event_143695_original-1.png", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/01\/event_143695_original-1.png", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/01\/event_143695_original-1.png", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2026\/01\/event_143695_original-1.png", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2026\/01\/event_143695_original-1.png", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2026\/01\/event_143695_original-1.png" }, "occurrence_count":1, "first_occurrence":21893656 } , "147183-21900500": { "datetime_modified":"20260329T120020", "datetime_start":"20260401T143000", "datetime_end":"20260401T153000", "has_end_time":1, "date_start":"2026-04-01", "date_end":"2026-04-01", "time_start":"14:30:00", "time_end":"15:30:00", "time_zone":"America\/Detroit", "event_title":"Learning seminar in algebraic combinatorics: C(-)ambrian Lattice II : c-sortable elements and c-clusters", "occurrence_title":"", "combined_title":"Learning seminar in algebraic combinatorics: C(-)ambrian Lattice II : c-sortable elements and c-clusters: Paul Mammen", "event_subtitle":"Paul Mammen", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Building on the type A example from last week, we will explore Cambrian lattices for general Coxeter groups.

This program culminated in the Veneziano amplitude which gave birth to string theory, but was abandoned as an approach to the strong force after the identification of Quantum Chromodynamics (QCD) as the microscopic theory of hadron physics. Yet QCD at low energies remains largely unsolved. I will describe how modern bootstrap methods, powered new theoretical insights and computational techniques, allow us to revisit this classic program with unprecedented rigor. Consistency of pion scattering \u2014 with minimal assumptions about the lightest resonances \u2014 leads to the emergence of Regge trajectories from the bootstrap bounds. The bootstrap approach becomes particularly sharp in the limit of a large number of colors. The low-lying spectrum of the extremal solutions shows a tantalizing, and still somewhat mysterious, quantitative proximity to the real-world meson masses. I will discuss what we are learning from these results and outline open questions on the path toward a bootstrap solution of large N QCD.", "occurrence_notes":null, "guid":"146256-21898732@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/146256", "building_id":"1000167", "building_name":"West Hall", "campus_maps_id":"163", "room":"340", "location_name":"West Hall", "has_livestream":0, "cost":"", "tags":["Physics","Science"], "website":"", "sponsors":[ { "group_name":"Department Colloquia", "group_id":"3804", "website":"" }, { "group_name":"Department of Physics", "group_id":"1965", "website":"" } ], "image_url":"", "styled_images":{ "event_thumb":"", "event_large":"", "event_large_2x":"", "event_large_lightbox":"", "group_thumb":"", "group_thumb_square":"", "group_large":"", "group_large_lightbox":"", "event_large_crop":"", "event_list":"", "event_list_2x":"", "event_grid":"", "event_grid_2x":"", "event_feature_large":"", "event_feature_thumb":"" }, "occurrence_count":1, "first_occurrence":21898732 } , "147181-21900498": { "datetime_modified":"20260328T212033", "datetime_start":"20260401T150000", "datetime_end":"20260401T160000", "has_end_time":1, "date_start":"2026-04-01", "date_end":"2026-04-01", "time_start":"15:00:00", "time_end":"16:00:00", "time_zone":"America\/Detroit", "event_title":"Exotic R4", "occurrence_title":"", "combined_title":"Exotic R4: Nathan Li", "event_subtitle":"Nathan Li", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Isomorphisms between objects that hold in the topological category but not in the smooth category, more concisely referred to as exotic phenomena, are central objects of study in topology and have guided the field's development for more than half a century.
