Are all trade policies created equal? empirical evidence for nonequivalent market power effects of tariffs and quotas

Over the past 50 years, the steel industry has been protected by a wide variety of trade policies, both tariff- and quota-based. We exploit this extensive heterogeneity in trade protection to examine the well-established theoretical literature predicting nonequivalent effects of tariffs and quotas on domestic firms' market power. Using plant-level Census Bureau data for steel plants from 1967-2002, we find evidence for significant market power effects for binding quota-based protection, but not tariff-based protection, particularly with respect to integrated and minimill steel producers. Our ...

Evidence for the Effects of Mergers on Market Power and Efficiency

Study of the impact of mergers and acquisitions (M&As) on productivity and market power has been complicated by the difficulty of separating these two effects. We use newly-developed techniques to separately estimate productivity and markups across a wide range of industries using detailed plant-level data. Employing a difference-in-differences framework, we find that M&As are associated with increases in average markups, but find little evidence for effects on plant-level productivity. We also examine whether M&As increase efficiency through reallocation of production to more efficient ...
