Plant level evidence on product mix changes in Chilean manufacturing

This article analyzes changes in the product mix by Chilean manufacturing plants in the period 1996-2003. Three quarters of the surviving plants changed the set of products produced and more than three quarters of the exporting plants changed the mix of products they exported during the sample period. Plants that changed their product mix contributed 85% of the aggregate growth in real sales of surviving plants between 1996 and 2003. Finally, and in contrast to the US evidence, there is a negative correlation between revenue per product and the number of products. Apart from this, new evidence consistent with recent models of multi-product heterogeneous firms and trade is provided.
