H. Benitez-Silva, M. Buchinsky, H.-M. Chan, S. Cheidvasser, and J. Rust, "How Large is the Bias in Self-Reported Disability?" Journal of Applied Econometrics, Vol. 19, No. 6, 2004, pp. 649-670. The ASCII file di_test.txt contains 388 observations and 131 variables written as a single vector. The first 388 rows are the observations of the first variable, the next 388 rows are the observations of the second variable, and so on. This file, which is in DOS format, is zipped in the file bbccr-data.zip. Unix users should use "unzip -a". These data are the result of using the Health and Retirement Study, waves 1 to 3 (public releases and freely available), to construct a sample of individuals that apply for SSDI or SSI (Disability Programs in the USA) benefits 6 months before or 6 months after one of the interview dates. The 131 variables are in the following order. The meanings of a number of the variables are quite obvious; those which are not include explanations. hid: household ID pid: person ID bvd: takes value 1 to 4, 1 if person is awarded and has an health limitation that prevents him or her from working, 2 if awarded without a hlimpw, 3 if not awarded with hlimpw, and 4 if neither accept: awarded benefits constant dimpute: did we have to impute any date related to the disability process?
