Total Factor Productivity (TFP) measures an economy's or company's efficiency by calculating the portion of output not explained by traditional inputs like labor and capital. Often considered the "secret sauce" of growth, it reflects advancements in technology, management, or workforce skill that allow more output with the same inputs.
Key Aspects of Total Factor Productivity
- Economic Significance: TFP accounts for a significant portion of the difference in income levels between rich and poor nations.
- Calculation: For small changes, TFP growth is roughly calculated by taking the output growth rate and subtracting the growth rates of labor and capital inputs.
- Alternative Name: TFP is often referred to as multi-factor
- Definition: TFP is the ratio of total output to the weighted average of inputs (usually labor and capital).
- Efficiency Metric: It measures how well inputs are utilized, rather than just how many are used.
- Drivers of TFP:
Growth in TFP is driven by innovation, technological advancements, better training, improved management practices, and better utilization of resources.
