💡 Solution & Explanation
The Solow residual represents the portion of economic growth unexplained by increases in capital and labor inputs, commonly interpreted as a measure of total factor productivity or technological progress. Robert Solow introduced this framework to demonstrate that capital accumulation alone is insufficient for sustained long-term growth. Measurement errors in labor quality and capital utilization can sometimes bias the estimation of this residual. Technological innovation remains the primary driver of sustained increases in total factor productivity.
