Erratum: “The Economic Consequences of Partisanship in a Polarized Era”

Abstract

The data and materials required to verify the computational reproducibility of the results, procedures, and analyses in this erratum are available on the American Journal of Political Science Dataverse within the Harvard Dataverse Network, at: https://doi.org/10.7910/DVN/R3GZZW. This erratum corrects errors in the published version of our article “The Economic Consequences of Partisanship in a Polarized Era” (McConnell et al. 2018). One of the authors was reviewing the replication materials as he prepared to file his thesis. After discovering a coding error, we decided to conduct a full audit from the original source files to search for further issues and subsequently identified a few additional errors. Resolving these errors did not substantively change either the statistical results or our substantive conclusions (in Tables 1 and 2, we present a comparison of the original and corrected estimates). No changes were required for Table 3. In some cases, reducing measurement error strengthened the original findings. The overall conclusion of Studies 1 and 2 was that workers and buyers had more positive assessments of copartisan firms and did not have more negative assessments of counter-partisan firms. None of the corrections contradicts those findings. Nonetheless, we deeply regret these errors. More detail on these corrections can be found in McConnell et al. (2020).
