We outline a model of endogenous choices of product scope as well as prices, quality, and output per product in a partial-equilibrium model of heterogeneous firms with arbitrary productivity. These choices depend on market characteristics including variable trade and fixed entry costs. The extent to which firms respond to shocks depends on their (potentially nonparametric) density around the zero-profit threshold. Accordingly, identical changes in, e.g., variable trade costs per product and market lead to vastly different responses across not only markets and products but also firms. We shed light on the heterogeneity of these responses by estimating parameters and otherwise calibrating the model to firm-and-product-level bilateral trade data for China.
