The Economic Impacts of Climate Change: Evidence from Agricultural Output and Random Fluctuations in Weather

American Economic Review, 2007 · paper · Economics

Appendix tables to a study of how climate change affects agricultural profits using random year-to-year weather fluctuations. They report how far county weather deviates from long-run normals and how county characteristics vary across temperature quartiles.

Wording Appendix Table 4 notes say "The second and third panels report p-values from F-tests that subsets of the variables are jointly equal to zero", but the second panel is headed "P-Values from Tests of Equality of Marginal Effects by Irrigation Status:"; only the third panel is headed "Tests that Listed Variables are Jointly Equal to Zero".

Judge's note: Page 5 image confirms the note and both panel headings. The second panel tests equality of marginal effects between irrigated and non-irrigated counties, which the note's wording does not describe. An equality test can be written as a test that differences are zero, so this is loose wording in the note; the numbers are not affected.

Second check: another model agreed

Typo The title ends with a footnote asterisk, "Random Fluctuations in Weather*", but no footnote text appears on the title page or anywhere else in the file.
  • p. 1 Title page, end of title
    Random Fluctuations in Weather*

Judge's note: Page 1 image shows the asterisk after "Weather" and nothing below the date "January 2007". The text of pages 2-5 contains only tables and their notes, with no asterisk footnote. The marker is orphaned, presumably left over from the article's title page.

Typo Appendix Table 1 note: "the deviation between a states’ yearly weather realization and the states’ long run average" uses the plural possessive for a single state; it should read "a state's ... the state's".
  • p. 2 Appendix Table 1, note, last sentence
    the deviation between a states’ yearly weather realization and the states’ long run average
  • p. 2 Appendix Table 1, note, last sentence
    a states’ yearly weather realization and the states’ long run average

Judge's note: Page 2 image shows the apostrophe after the s in both places, following the singular article "a". This is not an extraction artefact.

Typo Appendix Table 1 note defines the entries as "the fraction of counties with deviations at least as large as the one reported in the column heading" and then reads the example as "counties had deviations larger than 200, 800, and 1,400 degree days, respectively" (inclusive versus strict threshold).
  • p. 2 Appendix Table 1, note
    The entries report the fraction of counties with deviations at least as large as the
  • p. 2 Appendix Table 1, note
    counties had deviations larger than 200, 800, and 1,400 degree days, respectively
  • p. 2 Appendix Table 1 note
    counties had deviations larger than 200, 800, and 1,400 degree days

Judge's note: Page 2 image confirms both sentences as quoted. The example values match the 2002 degree-days row of Panel A (0.572, 0.187, 0.019 against 57%, 19%, 2%). For continuous weather data the two wordings give the same numbers, so this is only a loose-wording inconsistency.

Second check: none (judge only)

Report a problem with this finding
Typo Appendix Table 4 notes: "are the result of the estimation of version of equation (4) for agricultural profits that model" is missing an article or plural; it should read "versions of equation (4) ... that model" or "a version ... that models".
  • p. 5 Appendix Table 4, notes, second sentence
    are the result of the estimation of version of equation (4) for agricultural profits that model
  • p. 5 Appendix Table 4 notes
    result of the estimation of version of equation (4) for agricultural profits
  • p. 5 Appendix Table 4 notes
    the result of the estimation of version of equation (4)
  • p. 5
    estimation of version of equation (4) for agricultural profits that model

Judge's note: Page 5 image shows the sentence exactly as extracted, so it is not a line-break or extraction artefact. Singular "version" has no article and does not agree with the verb "model". The four columns suggest "versions" was intended.
