Converging to mediocrity: Trends in firm-level markups in the United Kingdom 2008–2019
研究了2008-2019年英国制造业企业加价率的下降趋势，发现加价率下降主要由企业内部因素驱动，暗示生产率放缓源于企业结构性恶化而非资源重新配置。
UK manufacturing productivity has declined sharply since 2008, yet little is known about the role of trends in firm-level markups in this context. We estimate firm-level markups using a structural demand approach with revenue shares and industry elasticities, which is complemented by a primal method. Findings indicate a decline in aggregate markups of two to five per cent from 2008 to 2019, driven mainly by within-firm declines. These results suggest that the UK’s productivity slowdown reflects structural deterioration within manufacturing firms rather than reallocation effects.
