Rent-sharing by workers can reduce the incentives for investment if some of the returns to sunk capital are captured in higher wages. We propose a simple measure of this "holdup" effect based on the size of the wage offset for firm-specific capital accumulation. Using Social Security earnings records for workers in the Veneto region of Italy linked to detailed financial data for their employers, we find strong evidence of rent-sharing, with an elasticity of wages with respect to potential rents per worker of around 4%, arising mainly at larger firms with higher price-cost margins. On the other hand, we find little evidence that bargaining lowers the return on investment. Instead, firm-level bargaining appears to split the rents after deducting the full cost of capital.
