Skills-Based Hiring

Employers are resetting degree requirements in a wide range of roles, dropping the requirement for a bachelor’s degree in many middle-skill and even some higher-skill roles. This reverses a trend toward degree inflation in job postings going back to the Great Recession. And while the Covid-19 pandemic accelerated this process, this reset began before the crisis and is likely to continue after it. By analyzing over 51 million job postings, this report reveals the prevalence of this degree reset and explores the potential for skills-based-hiring in the US.

Working from Home

We analyze the prevalence of working from home (WFH) in Germany using more than 35 million online job advertisements from 2014 to 2021. While a WFH option was rare in job ads before the crisis, the Covid-19 shock led to an unprecedented WfH boom. At the same time, regional, occupational, and sectoral inequalities in access to WFH have decreased during the pandemic. We also document a higher demand for digital skills, teamwork, and adaptability in job ads with a WFH option. We conclude with an outlook for the future of WFH.

Skills Gaps in the European Union

In this article, we address two questions: First, how prevalent are skills gaps in Europe? Second, what are the drivers of these skills gaps and how can workers better prepare for employers' skill demand?

Drawing on job ad data and survey data for 17 European countries, we create novel measures of skills gaps. We document, that manual workers face skill shortages, while cognitive workers exhibit skill surpluses. We further find that this Europe-wide pattern is strikingly consistent across all occupations and skill domains.
