A. Karlstrom, M. Palme, and I. Svensson, "A Dynamic Programming Approach to Model the Retirement Behavior of Blue-Collar Workers in Sweden", Journal of Applied Econometrics, Vol. 19. No. 6, 2004, pp. 795-807. There are two data files, both of which are ASCII files in DOS format. They are zipped in the file kps-data.zip. Unix users should use "unzip -a". The file sparadata.txt contains 51371 observations. index is an identifier for the observation (each individual and year) id2 is an identifier for the individual sex 1=man 2=woman year of observation age of the individual for the given year married marital status retire yes=1, no=0 income 1/1000 SEK. This number is rounded (no decimal digits) due to confidentiality reasons atp is the "average pension points" used in the paper The file surv.txt contains survival probabilities. Each line contains an age and a number less than 1. This number is the conditional survival probability, starting with age 30. That is, the first row contains the conditional probability of surviving to age 31, given that someone is alive at age 30. The last row contains the conditional probability for age 107. Anyone who reaches 108 is assumed to die with probability 1 before reaching age 109.
