LEDA - Ageing workers in the Austrian labour market - Linked Employer-employee Data Analysis

Motivation

Austria, like most industrialized economies, is facing rapid population ageing that is also apparent in the ageing of the workforce. While older workers bring valuable experience and firm-specific knowledge, they may face difficulties adapting to new technologies — raising questions about their role in a changing economy. It is, however, the technological advancements in which many countries put their hopes to countervail some of the potential negative effects an ageing workforce brings, when it comes to competitiveness on the global market. The question is therefore which conditions at the firm and individual level allow an older workforce to be employed productively.

Data

LEDA addresses these challenges by examining how the age composition of a firm's workforce is related to firm productivity, and how this relationship differs by the degree of technology, and specific characteristics at the firm and individual level. We leverage comprehensive register-based data from the Austrian Micro Data Center (AMDC) covering the years 2013 to 2022, linking the following registers:

  • on the workers´ side, the Register-based Labour Market Statistics (dt.: AEST_REGZ Abgestimmte Erwerbsstatistik und Registerzählung)
  • on the firms´ side, the Structural Business Statistics  (dt.: LSE – RE Leistungs- und Strukturstatistik)

This detailed data infrastructure allows us to analyse characteristics of the workforce and at the firm-level together, capturing dynamics that are often missed in survey-based studies.

Research Questions

The project is guided by the following key research questions:

  • What is the relationship between firm productivity and the age structure of the workforce controlling for firm level and workers characteristics?
  • What role do technological intensity or workforce education play in shaping this relationship?
  • How does the strength of this relationship vary with firm heterogeneity, for example by firm size or economic sector?

Extensive descriptive analysis reveals substantial heterogeneity across Austrian firms—not only in terms of firm size, but also with respect to workforce composition (e.g., education, migration background, part-time employment) and key economic characteristics such as capital intensity, labour costs, and total value added.

Building on these insights, the econometric analysis - drawing on fixed effects models, generalized method of moments estimators (GMM), and Bayesian approaches - aims to identify the relationship between workforce ageing and firm productivity. By combining rich register data with rigorous econometric analysis, the project contributes to a deeper understanding of this societally and economically highly relevant issue, with tailor-made answers for the Austrian case. The findings will support policymakers in designing strategies to harness the potential of older workers and promote inclusive and resilient economic transitions amid ongoing demographic and technological change.
