Irene Botosaru and Federico H. Gutierrez, "Difference-in-Differences when Treatment Status is Observed in Only One Period", Journal of Applied Econometrics, Vol. 33, No. 1, 2018, pp. 73-90. The data used in this paper are the Peruvian Encuesta Nacional de Hogares (ENAHO). All rounds of the household survey are publicly available at www.inei.gob.pe The files in this folder contain all the information to replicate results in the paper. The description of the lFiles is as follows: DATA ```` b1_women.dta: stata 14 format dataset containing the women sample b2_children.dta: stata 14 format dataset containing the children sample b1_women.csv: comma-separated format dataset containing the women sample b2_children.csv: comma-separated format dataset containing the children sample VARIABLES `````````` ubigeo district id facpob sample weight ysurvey year of survey age age male gender contraceptives contraceptive use nodoctor no doctor when sick cfamiliar family planning consultation cvacunas vaccination wall1 wall material: ladrillo o bloque cemento wall2 wall material: adobe o tapia wall3 wall material: madera floor1 floor material: cemento floor2 floor material: tierra roof1 roof material: cania, ester, estera con barro, paja, hojas de palmera, etc roof2 roof material: planchas de calamina, fibra de cemento hjuntos household in JUNTOS maxyedu maximum education adults CODES FOR PAPER AND ONLINE APPENDIX ``````````````````````````````````` a1_code_for_paper.do: A stata do-file that replicates all results in the paper except Figure 5 included in the other do-file.

LOG FILES WITH RESULTS `````````````````````` c1_results_code_for_paper: This is the log file after computing the do-file a1_code_for_paper.do c2_results_code_for_online_appendix: This is the log file after computing the do-file a2_code_for_online_appendix.do The .dta files are zipped in the file bg-dta-files.zip. All other files are zipped in the file bg-text-files.zip. Since all files in bg-text-files.zip are ASCII files in DOS format, Unix/Linux users should use "unzip -a". Federico H.
