Job market paper abstract: I investigate the effect of clean technology adoption on labor market outcomes. I leverage a demand-side heat pump subsidy shock in France that triggered supply-side adoption by heating firms, creating a natural experiment for studying worker adjustment. Using matched employer-employee data, I find establishment-level adoption increases both job creation and separations, indicating within-firm labor reallocation. Workers experience an average +10% rise in hours worked and +12% rise in earnings, challenging fears of severe adaptation costs. Decomposing by worker type, I find that stayers drive the results, with 20% higher hours and earnings. Both leavers and newcomers face initial losses; however, within one year, leavers are overcompensated and newcomers recover to baseline. Subsidy-driven technology adoption therefore results in low transition costs, avoiding mass displacement and directly updating workers' skills.
