Liqiu Zhao (KU Leuven) discusses Price Competition versus Externalities
ABSTRACT: Agglomeration can affect markups through two potential channels: agglom- erated regions toughen competition (price competition effect) and firms are more productive on average in agglomerated regions (agglomeration exter- nalities and firm selection effect). However, the literature is inconclusive on which force dominates. This paper models these two channels by in- troducing agglomeration economies to the model of Melitz and Ottaviano (2008). Under parameters from the empirical studies, I demonstrate that the price competition effect tends to dominate the others, i.e., firms in more agglomerated regions charge lower markups. Using a unique Chinese firm-level data from 2002 to 2004, I investigate the effect of spatial agglomeration on markups of firms. By addressing the potential endogeneity problems us- ing instrumental-variable method, I find that in China an increase in the number of own-industry firms in the same region has a negative causal effect on markups of firms and a positive effect on productivity. But firms in agglomerated regions have higher output and profit.
