Computerization Knowledge Gap measures

This measure was developed for our paper "Computerization, Obsolescence and the Length of Working Life" by Péter Hudomiet and Robert J. Willis. The measure is an estimated probability that an older worker does not use computers at work even though computers would be useful in his or her job. The detailed explanation of the development of this measure is available in the paper and in the Supplementary Online Appendix.

This file includes instructions for merging the file to other datasets.

This is the basic version of the measure.

This is the extended (and preferred) version of the measure.

Matlab code for estimating instrumental variable quantile regressions

• • This is the estimator; and this computes the standard errors.

  • The code is based on inv_qr available at Christian Hansen's website.

  • My code allows the use of weights.

  • It uses built-in matlab optimization functions to improve precision and speed up convergence.
