講座內(nèi)容：

The competitive advantage of large multi-product exporters primarily stems from a few“superstar”products, rather than a broad product portfolio. This paper finds that the larger the exporter, the more its success relies on a handful of exceptionally performing core products. This concentrated product structure is pervasive both across firms and within firms over their life cycle. Moreover, when trade costs fall, the heterogeneity in the importance of superstar products across firms becomes even more pronounced. To explain this phenomenon, this paper develops a dynamic general equilibrium multi-product trade model incorporating endogenous decisions on product innovation and riskiness investment. The model’s predictions are consistent with empirical patterns in the data.
