SUMMARY:Workshop / Seminar:EXPERIMENTALLY VALIDATING WELFARE EVALUATION OF SCHOOL VOUCHERS
DESCRIPTION:We leverage a unique two-stage experiment that randomized access to private school vouchers across markets as well as students to estimate the revealed preference value of school choice. To do this\, we estimate several choice models on data only from control markets before turning to the treatment data for model validation. This exercise reveals that a model where school choice is constrained by ability-to-pay achieves better out-of-sample fit but still underpredicts experimental take-up of the voucher offer. We then present evidence from treatment markets that: a) the voucher offer also induced search\; and b) private schools used program surplus to incentivize enrollment. Further\, we show that a unified model incorporating these features can explain both the control and treatment data patterns. Estimates from that model imply that a targeted voucher program would have a marginal value of public funds(MVPF) of at least 3.

SUMMARY:Workshop / Seminar:Learning Seminar in Algebraic Combinatorics: Projective system of posets from set partitions
DESCRIPTION:It is known when we call a poset P\, a P-chain permutational poset\, given a subset of permutations\nP of the symmetric group S_n. In this work\, we use the same idea to study subsets of words of length n\,\nthat are not necessarily permutations\, for example: especially when they are certain classes of restricted\ngrowth functions induced by set partitions in standard form over [n] = {1\, 2 · · · n}. Varying n only\, and\nalso varying n and k (the number of blocks of the set partitions) simultaneously\, we can show that those\nposets form a projective system of trees and lattices. These poset structures can be extended over signed\nrestricted growth functions for standard type B set partitions over 〈n〉 = {−1\, −2\, · · · n\, 0\, 1\, 2 · · · n} as\nwell. We investigate properties of the tree and lattice structures of these projective systems.
