The impact of immigration on native wages remains a contentious issue in labour economics. This meta-analysis synthesises evidence from 88 studies published between 1985 and 2023, offering a comprehensive assessment of reduced-form estimates. We document substantial heterogeneity across estimates and show that contexts and empirical designs systematically shape reported effects. In particular, shift-share instrumental-variable strategies correct the upward bias seen in OLS estimates. Our findings emphasise the necessity for replication and enhanced transparency in methodological reporting.
