Does importing intermediates increase the demand for skilled workers? Plant-level evidence from Indonesia

AbstractThis paper examines whether starting to import contributes to skill upgrading among Indonesian plants. Our data records the distribution of years of employee schooling in each plant. We examine how starting to import affects the demand for highly educated workers within and across production and non-production occupations categories at the plant level. We estimate a model of importing and skill-biased technological change in which selection into importing arises due to unobservable heterogenous returns from importing. Both instrumental variable regression and marginal treatment effect estimates confirm that importing has substantially increased the relative demand for educated workers within each occupation. In contrast, we do not consistently estimate a significant impact of importing on the relative demand for non-production workers
