Using firm-to-firm transactions, we show that starting to supply a ‘superstar’ firm (large domestic firms, exporters and multinationals) boosts productivity by 8% in the medium-run. Placebos on starting relationships with smaller firms and novel identification strategies support a causal interpretation of “superstar spillovers”. Consistent with a model of technology transfer, we find falls in markups and bigger treatment effects from technology-intensive superstars. We also show that the increase in new buyers is particularly strong within the superstar firm's network, a “dating agency” effect. This suggests an important role for raising productivity through superstars' supply chains regardless of their multinational status.
