This paper documents firm mark-ups and competition in Australia, and their impact on productivity, using administrative data. I find that mark-ups increased by around 5 per cent since the mid 2000s, less than previously documented for Australia and slightly less than documented for the average advanced economy. While part appears to reflect technological change, part appears to reflect an increase in market power. This increase appears to explain part of the slowdown in productivity growth observed in Australia over the past decade, by slowing the efficient reallocation of resources from low productivity to high productivity firms.

产品市场竞争及其对澳大利亚经济的影响*

本文使用行政数据记录了澳大利亚的公司加价和竞争，及其对生产力的影响。我发现自 2000 年代中期以来，加价幅度增加了约 5%，低于澳大利亚先前记录的水平，也略低于发达经济体平均水平的记录水平。虽然部分似乎反映了技术变革，但部分似乎反映了市场力量的增加。这种增长似乎可以部分解释澳大利亚在过去十年中观察到的生产率增长放缓，原因是资源从低生产率企业向高生产率企业的有效重新分配速度放缓。
