Result
ΔlnA = ΔlnY − αΔlnK − (1 − α)ΔlnL. Log changes are dimensionless, not ordinary percentage changes or annualized rates.
The residual includes measurement error, capacity utilization, institutions and other omitted influences. It cannot be interpreted as pure technological progress. This constant-share calculation is not a causal estimate.
Numbers are rounded to 10 significant digits for display.
