INASHI – Information frictions in hiring decisions

Over the last decades, internet has sped up and increased interactions between employers and workers, but aggregate unemployment  does not seem to have been much impacted by this revolution. This could be because information frictions are not a first-order contributor of unemployment, or because current tools and institutions do not enable truthful and effective communication between firms and workers.

Employers, who are often on the short side of the market, find it difficult and costly to screen potential employees. INASHI aims to provide theoretical frameworks and new empirical evidence about what the remaining information imperfections on the labour market are, how important they are to aggregate unemployment and unemployment of the most vulnerable segments of the labour market, and what solutions can be put in place to improve the recruiting process.

INASHI will combine novel data on how firms search for workers on large online job boards with administrative data on vacancies, and matched employer-employee data.

It will also leverage a series of randomised controlled trials to test how the provision of new information to employers, whether about candidates or about features of the market, help them make better hiring decisions, leading ultimately to higher aggregate hiring, and higher-quality matches.

Three countries will be studies, Austria, France and Sweden, so that INASHI will provide evidence valid in a variety of contexts.

Project A – Improving Employers’ Access to Job Seekers’ Skills Information

  • Innovative approach: INASHI is developing and testing new ways to provide employers with reliable information about job seekers’ skills, in collaboration with France Travail.
  • Pilot phase: A proof-of-concept evaluation is underway to assess the effectiveness of an incentivised résumé rating system.

Project B – Informing Employers About Labour Market Conditions

  • Large-scale experiment: A randomised controlled trial was launched in France (October 2025) to provide firms with data on wage distributions in their labour market. Initial results are expected in early 2026.
  • International collaboration: A complementary experiment is being prepared in Austria, focusing on informing employers before they post job vacancies. This will include a survey to better understand the impact of wage information on hiring decisions.

Project C – Employer Preferences for Vocationally Trained Job Seekers

  • Key findings from correspondence study:
    • Employers value degrees from vocational training nearly as much as those from traditional education.
    • Short training programmes do not significantly increase callback rates for job seekers.
  • Next steps: An incentivised résumé rating system is in development, with a planned launch in early 2026.

Recent Milestones

  • Launch of French experiment: A major randomised controlled trial, in partnership with France Travail, is now underway to test the impact of wage information on employer behaviour.
  • Upcoming publication: A working paper summarising the findings from the correspondence study (Project C) will be released soon.

Collaborations and Partnerships

  • Expanding research team: The project has attracted researchers from leading institutions in France and Austria, strengthening its interdisciplinary approach.
  • Institutional support: Ongoing collaboration with public employment services in France and Austria, ensuring that research insights are grounded in real-world labour market challenges.

What’s Next in 2026

  • Data analysis: The first results from the French wage information experiment will be analysed and shared.
  • New interventions: The incentivised résumé rating system (Project C) will be launched, offering further insights into employer decision-making.
  • Scientific dissemination: Findings from all projects will be presented at conferences and in academic publications.
