The Relationship between the Markup and Inflation in the G7 Economies and Australia
对七国集团和澳大利亚的通货膨胀与加成率进行I(2)分析，发现价格和成本为I(2)过程，除日本外，价格与成本的对数线性组合形成一阶单整的加成率，且加成率与通货膨胀存在协整关系，长期中高通胀伴随低加成率。
An I(2) analysis of inflation and the markup is undertaken for the G7 economies and Australia. We find that the levels of prices and costs are best described as I(2) processes and that, except for Japan, a linear combination of the log levels of prices and costs cointegrate to the markup that is integrated of order 1. It is also shown that the markup in each case co-integrates with inflation and that higher inflation is associated with a lower markup in the long run.
