Résumé : We introduce a “forensic” approach to detect informal employment arising from migration shocks and assess its effects on firms. Exploiting large, exogenous inflows of irregular migrants to southern Italian coasts, we use vineyard microdata to identify anomalies in labor productivity (quantity per reported hour) as markers of unreported work. Following the shock, about 80% of exposed farms—particularly small, remote ones—exhibit abnormally high reported (relative to predicted) productivity. Analyzing other outcomes of these farms reveals no changes in reported sales, prices, or hourly wages (already near the minimum), but a significant reduction in labor costs mirrored by higher profits. With quantities and non-labor costs unaffected, anomalous productivity spikes imply a 7% increase in informal employment.
