Does slower technology diffusion explain the widening gap between firms?
Core argument: Labor productivity has risen at the global frontier while divergence between frontier and laggard firms has widened, a gap that persists after accounting for capital deepening and mark-up behavior and indicates broader technological divergence.
The global productivity slowdown is characterized by rising labor productivity at the global frontier and increasing divergence between frontier and laggard firms. This divergence persists even after accounting for capital deepening and mark-up behavior, indicating a broader technological divergence. Structural changes like digitalization and globalization may drive rapid productivity gains at the frontier, yet aggregate multi-factor productivity (MFP) is weaker in industries with pronounced MFP divergence. This suggests a slowdown in the diffusion process, potentially due to higher costs for laggard firms transitioning to an idea-based economy, rising entry barriers, and declining market contestability. The extreme rise in MFP divergence in sectors with limited pro-competitive reforms highlights policy weaknesses stifling diffusion in OECD economies.
