Productivity raises wages more in wealthier countries

Research area:EconometricsEconomics and EconometricsPanel data

What the study found

The study found a threshold effect in the relationship between productivity and real wages. In lower-income countries, productivity gains were associated with only modest increases in real wages, while in wealthier countries the link was substantially stronger.

Why the authors say this matters

The authors conclude that economic development increases how sensitive wages are to productivity gains. They say this has important implications for labor market policy and wage-setting policy.

What the researchers tested

The researchers examined annual data from 34 developed and developing countries from 1998 to 2022. They used a two-step approach: a static panel threshold model to look for nonlinear patterns, and then a dynamic panel threshold regression model by Seo and Shin, using GDP per capita as the threshold that separates countries by development level.

What worked and what didn't

The threshold analysis showed that the wage-productivity link differs by income level. Productivity gains translated only weakly into higher real wages in lower-income countries, but the effect was much stronger in higher-income countries.

What to keep in mind

The abstract does not describe specific limitations beyond the study's scope and design. The results are based on a panel of 34 countries over 1998 to 2022 and on GDP per capita as the development threshold.

Key points

  • The study finds a threshold effect in the productivity–wage relationship.
  • Lower-income countries show only modest real wage gains from productivity increases.
  • Higher-income countries show a stronger productivity-to-wage link.
  • The analysis covers 34 developed and developing countries from 1998 to 2022.
  • GDP per capita was used to separate countries by development level.
