Abstract: | This paper is aimed at analyzing the relationship between outsourcing and productivity. Specifically, this paper deals with outsourcing at the firm level and focuses on the role of contracting out of manufacturing activities. I obtain new insights on this topic, mainly using a precise measure for outsourcing and analyzing differences across industries. Using an unbalanced panel of Spanish manufacturing firms, I estimate a production function depending on traditional inputs (labor, capital, and materials) and an index of production subcontracting. I find that for manufacturing as a whole, outsourcing intensity has a positive effect on productivity, showing an elasticity of output with respect to outsourcing around 0.15. When analyzing industry level results, I find that outsourcing intensity has a positive effect on productivity, mainly for firms belonging to light industries. |
