Due to an oversight that was only noticed after the online publication of Meyer (2009), a mistake has been published in the formula reported Footnote 1 of “Editorial: Motivating, testing, and publishing curvilinear effects in management research” (DOI: 10.1007/s10490-008-9122-3). The correct wording of the footnote should be as follows:

“This application of algebra on the regression coefficients goes as follows: If the estimation yields a coefficient β 1 on a linear effect and β 2 on the corresponding quadratic effect, this corresponds to a function of the form β 1 x + β 2 x 2 . Taking the first derivative and setting it to zero yields β 1 + 2β 2 x = 0, and thus the turning point at x = (-β 1 /2β 2 ).”

We apologize for any inconvenience caused.
