We demonstrate the usefulness of our results by using them to shed light on the existing empirical evidence. In particular, we argue that the studies of Syverson (2004), Schmitz (2005), and Lagakos (2007) are examples of how differences in the market size affect productivity. Our results are consistent with the positive relationship between competition and productivity that these studies find. In contrast, the study of Aghion et al (2005) is an example of how differences in entry costs affect productivity. Our results are consistent with the inverted U shape relationship that this study finds.
