This article explores whether the nature of imports matters when examining the effects of trade on plant-level labour outcomes. Previous literature that examines this question mainly considers imported intermediate inputs as a homogenous group and is unable to reach a consensus on the effects of input tariff liberalization on employment and wages of skilled and unskilled workers. Exploiting detailed product-level information available on intermediate inputs from plant-level data for the Indian manufacturing sector, I distinguish between plants that import mainly for quality considerations as opposed to plants that seek imports as cheaper alternatives to domestic inputs. I find that strong complementarities exist between skilled workers and imported inputs for plants importing high-quality inputs. For plants importing intermediate inputs mainly as a cost-cutting strategy, input tariff liberalization leads to an increase in employment of both skilled and unskilled workers, but a decline in skill composition. This can best be explained as a strategy that achieves economies of scale. On average, as input tariffs liberalize, importing plants employ more workers and pay higher wages than non-importing plants.
