• Abstract summary: We examine how job contents evolve as new technologies substitute for tasks, shifting required skills rather than eliminating entire jobs. We find that re-skilling pressure is greatest for low-skilled occupations when accounting for distance between skills. Jobs from large employers and markets experienced less change relative to small employers and markets, and non-white workers in low-skilled jobs are most demographically vulnerable.

• Abstract: Substantial scholarship has estimated the susceptibility of jobs to automation, but little has examined how job contents evolve in the information age as new technologies substitute for tasks, shifting required skills rather than eliminating entire jobs. Here we explore patterns and consequences of changes in occupational skill and characterize occupations and workers subject to the greatest re-skilling pressure. Recent work found that changing skill requirements are greatest for STEM occupations. Nevertheless, analyzing 167 million online job posts covering 727 occupations over the last decade, we find that re-skilling pressure is greatest for low-skilled occupations when accounting for distance between skills. We further investigate the differences in skill change across employer and market size, as well as social demographic groups, and find that these differences tend to widen the economic divide. Jobs from large employers and markets experienced less change relative to small employers and markets, and non-white workers in low-skilled jobs are most demographically vulnerable. We conclude by showcasing our model's potential to precisely chart job evolution towards machine-interface integration using skill embedding spaces.

  This study aims to understand whether employers have begun focusing more on individual skills rather than formal qualifications in their recruitment processes. Our findings provide evidence that employers have initiated "skill-based hiring" for AI roles. In occupations with high demand for AI skills, the premium for skills is high, and the reward for degrees is relatively low.

  Rapid technological innovation threatens to leave much of the global workforce behind. Governments and markets must find ways to quicken the rate at which the supply of skills reacts to changes in demand. This paper presents a pipeline which makes one-shot multi-step forecasts into the future using a decade of monthly skill demand observations.

  Statistical discrimination emerges in agent policies as a function of both the bias in the training population and of agent architecture. We show that less discrimination emerges with agents that use recurrent neural networks, and when their training environment has less bias.

• Discovering Generalizable Skills via Automated Generation of Diverse Tasks [82.16392072211337]
  We propose a method to discover generalizable skills via automated generation of a diverse set of tasks. As opposed to prior work on unsupervised discovery of skills, our method pairs each skill with a unique task produced by a trainable task generator. A task discriminator defined on the robot behaviors in the generated tasks is jointly trained to estimate the evidence lower bound of the diversity objective. The learned skills can then be composed in a hierarchical reinforcement learning algorithm to solve unseen target tasks.

  We employ survey data together with social media data to analyse personality, moral values, but also cultural elements of the young unemployed population in Italy. Our findings show that there are small but significant differences in personality and moral values, with the unemployed males to be less agreeable. Unemployed have a more collectivist point of view, valuing more in-group loyalty, authority, and purity foundations.

We reformulate the JTB as the task of link prediction over the Job-Graph that matched job titles should have links.
