# What this package reproduces

Generated when the package was published, from its own targets and its own output, so
it cannot claim something the code does not do.

**24 of the 30 numbers this paper prints for these tables are reproduced.**

Cells are named as they are in `results.json`. The reason for each follows the table.

Table 3's note says the standard errors are clustered at the study level. The published Panel A was estimated without clustering: heteroskedasticity-robust standard errors reproduce every printed t-statistic exactly, and the authors' log of the published run carries no cluster option. This package reports both. Clustered by study the coefficients are unchanged and the inference is weaker: the standard-error term gives t = -1.73, p = 0.091 by OLS and t = -1.76 by IV, against printed t of -5.18 and -4.81, and the constant gives t = 0.87, p = 0.388 against a printed 1.69 and 0.099. Both sets are in results.json. The printed values are left exactly as published.

The printed z carries no sign. It must be negative: the coefficient is -0.133, the p-value is 0.153, and every other cell in the table is signed. The authors' log gives -1.43. The printed value is left as published.
