The relationship between productivity and salary increases: an exploratory study

Summary

This exploratory study investigated the dynamic relationship between productivity and salary increases, particularly within the South African context. The research aimed to determine the causal direction between these two critical variables, hypothesizing that salary increments might precede or Granger cause productivity. The methodology likely involved statistical analysis to assess the strength and direction of the relationship, with a specific focus on examining scenarios where productivity was treated as the dependent variable and salary increments as the independent variable. The findings revealed a significant unidirectional causal relationship, where salary increments were found to precede productivity. Specifically, the study established that the association between the two variables was considerably stronger when salary increments were considered the independent variable influencing productivity. This suggests a departure from the conventional view that salary increases primarily serve as a reward for demonstrated productivity. The implications of these findings are substantial, indicating that South African employers predominantly utilize salary increments as a proactive tool to stimulate and drive future productivity, rather than a retrospective compensation for past performance. This approach aligns with broader national economic initiatives, such as the Accelerated and Shared Growth Initiative for South Africa (AsgiSA), which aimed to boost economic growth. The study implies a strategic use of remuneration policies to foster productivity, connecting micro-economic salary decisions with macro-economic growth objectives.
