Multi-Product Firms, Endogenous Sunk Costs, and Gains from Trade through Intra-Firm Adjustments

In this paper, I investigate welfare gains associated with trade
induced intra-firm adjustments of multi-product firms. To
disentangle the welfare gains, I split up the R&D portfolio of
a multi-product firm into three different channels: i) product
innovation, ii) investments in the degree of product
differentiation, and iii) process innovation. Trade integration
enables firms to exploit economies of scale as innovation requires
upfront development costs and encourages firms to spend more on
R&D. I derive the indirect utility function and show that
consumers bene.t from this behavior through a larger product range
(love of variety) which is also more differentiated (love of
diversity). Furthermore, a larger market is associated with
technology upgrading. The resulting cost savings are passed on to
consumers, leading to welfare gains from lower prices.
