Pergunta feita ao analista

Did Michigan manufacturing firms that received a job-training grant reduce their scrap rates in the year after they received it, compared with how the same firms did in other years and allowing for common changes over 1987-1989? Report the effect on the log scrap rate.

Resposta

Estimativa (infer.ols): coef.grant_1 = -0,4216.

não conferido · Not verified against the book or a readable reproduction (2026-10-15). The figures are those of research-papers.md section 3.21 and agree with a search engine's summary of a University of Regensburg exercise sheet (WOE_ws19_bl7.pdf) that reprints Table 14.1; that sheet now returns 404 and no archived copy exists. Data fact checked before any estimate: 162 firm-years (54 firms x 1987-1989) are complete on lscrap, grant, grant_1, d88 and d89.
Desvio conhecido
não conferido
Recorded before this track's software-reference run and before any dry run on this target; from the source's status: the textbook was not read and no reproduction of its printed Example 14.1 output could be opened (a Regensburg exercise sheet that reprints Table 14.1 now answers 404; only a search engine's summary of it was seen, which gives grant -0.252 (0.151) and grant_1 -0.422 (0.210), n = 162, the figures research-papers.md section 3.21 records). The printed cells are therefore 'unverified': recorded and counted in replication fidelity, non-required on T1.

    Did Michigan manufacturing firms that received a job-training grant reduce their scrap rates in the year after they received it, compared with how the same firms did in other years and allowing for common changes over 1987-1989? Report the effect on the log scrap rate.

    jtrain (agent)

    Wooldridge's JTRAIN data (Holzer, Block, Cheatham and Knott's Michigan job-training survey; R package wooldridge): one row per firm and year, 157 firms over 1987-1989 (471 rows); scrap rates exist for a subset of firms. Columns: rownames, a row number; year; fcode, firm code; employ, employees; sales, annual sales (dollars); avgsal, average employee salary; scrap, scrap rate (per 100 items); rework, rework rate; tothrs, total hours of training; union, 1 if unionized; grant, 1 if the firm received a job-training grant in that year; d88 and d89, 1 for 1988 and 1989; totrain, total employees trained; hrsemp, training hours per employee; lscrap, log of scrap; lemploy, lsales, lrework, lhrsemp, logs of those columns; lscrap_1, lscrap lagged one year; grant_1, grant lagged one year; clscrap, cgrant, clemploy, clsales, lavgsal, clavgsal, cgrant_1, chrsemp, clhrsemp, first differences and logs of the named columns.
