Multi-Product Firms, Quality Differentiation and Comparative Advantage

This paper introduces a new theoretical model to explore how the behavior of heterogeneous intermediate suppliers affects the product quality choice of heterogeneous final good producers. It explains the choices of quality, inputs and the export prices of a multi-product firm in response to different market characteristics. We found that a more productive firm exports a larger and higher qualit...

Multi-Product Firms and Trade Liberalization∗

Firms’export decisions depend on a combination of firm “productivity” and firm-product-country “consumer tastes”, both of which are stochastic and unknown prior to the payment of a sunk cost of entry. Trade liberalization induces endogenous reallocations of resour...

Higher firm-level ability raises a firm’s productiv...
