Imported Inputs and Productivity
- (pp. 3660-3703)
Abstract
We estimate a model of importers in Hungarian microdata and conduct counterfactual analysis to investigate the effect of imported inputs on productivity. We find that importing all input varieties would increase a firm's revenue productivity by 22 percent, about one-half of which is due to imperfect substitution between foreign and domestic inputs. Foreign firms use imports more effectively and pay lower fixed import costs. We attribute one-quarter of Hungarian productivity growth during the 1993-2002 period to imported inputs. Simulations show that the productivity gain from a tariff cut is larger when the economy has many importers and many foreign firms. (JEL D24, F13, F14, L60)Citation
