Chinese competition and network effects on the extensive margin

I construct a network of input-output linkages in Chilean manufacturing and show that a negative demand shock has an impact on the number of firms producing in sectors that supply the sectors affected by the shock. Approximately one-third of the effect of increased Chinese competition on the extensive margin can be attributed to these network effects. The observed effect is a combination of multiproduct firms dropping varieties and firms leaving the market. I also study whether there is evidence of 'cascading failures' that could amplify the impact of idiosyncratic shocks. I find no evidence of these 'cascading effects'.
