Multiproduct Firms and Trade Liberalization

Abstract: This paper develops a general equilibrium model of multi-product firms and analyzes their behavior during trade liberalization. Firm productivity in a given product is modeled as a combination of firm-level "ability" and firmproduct-level "expertise", both of which are stochastic and unknown prior to the firm's payment of a sunk cost of entry. Higher firm-level ability raises a firm's productivity across all products, which induces a positive correlation between a firm's intensive (output per product) and exte… Show more

“…The estimated parameters for the human capital variable (luni) and R&D (R_D) display positive signs and are statistically significant at the 1% level. 6 This means that R&D activities and the share of workers with university degrees in total employment are positively related to the probability of exporting.…”
