<Abstract>

We examine the rate of substitution of jobs by artificial intelligence using a score called the “weighted ability rate of substitution (WARS).”WARS is a indicator that represents each job’s potential for substitution by automation and digitalization. Since the conventionalWARS is sensitive to the particular responses from the employees, we consider a robust version of the indicator. In this paper, we propose the individualized WARS, which is a modification of the conventional WARS, and compute robust averages and confidence intervals for inference. In addition, we use the clustering method to statistically classify jobs according to the proposed individualized WARS. The proposed method is applied to Korean job data, and proposed WARS are computed for five future years. Also, we observe that 747 jobs are well-clustered according to the substitution levels.
