SUMMARY:Workshop / Seminar:Barriers to Benefits: Unemployment Insurance Take-Up and Labor Market Effects (with Casey McQuillan)
DESCRIPTION:Unemployment insurance (UI) take-up is relatively low in the United States. 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.

SUMMARY:Workshop / Seminar:GLNT: How you think on a function defined on 0\,1\,…\,N-1?
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\,…\,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—due to Auslander-Tolimieri—to 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\,…\,N-1?                              \n\nEngineers tell us that there are two answers for this question:\n\n(A) as functions on that set\, where 0\,1\,…\,N-1 regarded as times\; and\,\n\n(B) as functions on that set\, where 0\,1\,…\,N-1 regarded frequencies\;\n\nand then the FT is an operator translating between the two spaces. \n\nIn the lecture\, I will explain that there is another answer\, i.e.\, a not so well-known third space (C)\, of arithmetic nature\, that also gives an answer to the above question\, and then the FFT appears simply as the composition of two operators: \nthe one translating between spaces (A) and (C)\, and the one that translates (C) to (B).\n\nRemark: The lecture is prepared to be understood by undergraduate students (from any department) who took basic course in linear algebra.
