Innovation and Trade in the Presence of Credit Constraints

This paper examines how trade liberalization affects investments in R&D at the firm level. We provide a model with entrepreneurs differing in their wealth endow-ment, causing them to rely differently on external funds. In the presence of capital market imperfections, this implies heterogeneous access to external funds such that poor entrepreneurs run smaller firms, are less likely to invest in R&D, and more likely to exit the market. Decreasing trade costs resulting from tariff reductions exacerbate these characteristics. Using firm-level panel data on seven Latin American countries for 2006 and 2010, we find support for our theoretical predictions. While recent studies emphasize a positive impact of trade liberalization on firms ’ productivity-enhancing activities, we provide novel evidence showing that financial constraints can impair the effect on R&D efforts. These results suggest that imperfect capital markets can prevent welfare gains from trade liberalization to materialize
