We take measures regarding the authentic content ensuring the privacy of our customers, and believe in the transparent approach to the writing process. The reason we are not using common plagiarism checkers is simple: they save the copy of an essay to the database, which can later result in identical work. To take care of our customers and make the order system easier, we apply our own ways. If you are thinking of your next step of the order process, you can contact us for an essay, research paper, academic assignment, lab report or a speech, and we will be happy to assist.
In his recent paper, Sherk (2015) critiques the Gould and Shierholz (2011) methods. Since this paper serves as an update to their methods, we use the most recent data presented here to test some of his criticisms. Primarily, we defend our methods against the idiosyncratic empirical model choices Sherk (2015) uses. Secondarily, we explore some suggestions Sherk (2015) makes regarding the cost-of-living methodology to control for possible measurement error. As shown in Table 3 , and as will be discussed in detail below, in all cases we find that his suggestions do not change, in a statistically or economically significant way, the estimated RTW wage differential. (All of the models in Table 3 should be compared against the final model in Table 2. Full regression results are reported in Appendix Table A2.)
