| Markups, Entry Regulation and Trade: Does Country Size Matter?* (2007) | |||||||||||||||||
Abstract | |||||||||||||||||
| Actual and potential competition is a powerful source of discipline on the pricing behavior of firms with market power. A simple model is developed that shows that the effects of import competition and domestic entry regulation on industry price-cost markups depend on country size. Barriers to domestic entry are predicted to have stronger anti-competitive effects in large countries, whereas the impact of barriers to foreign entry (i.e., imports) should be stronger in small countries. Following estimation of markups for manufacturing sectors in 41 developed and developing countries, these hypotheses are tested and cannot be rejected by the data. For example, although India and Hungary impose the same number of regulations on entry of new firms, their impact on manufacturing markups is 11 percent higher in India due to its larger size. Similarly, New Zealand and Zimbabwe have the same import penetration ratio, but the market discipline effect of imports on markups is 13 percent higher in Zimbabwe due to its smaller size. | |||||||||||||||||
