description: "????????? Cobb-Douglas production function"
formula: "Y* = A * K^?? * L^(1-??)"
variables:
Y_star: "Potential GDP"
A: "Total Factor Productivity (TFP)"
K: "Capital stock"
L: "Potential labor input"
alpha: "Capital share (typically 0.3-0.4)"
steps:
- "Estimate potential labor (NAIRU-based)"
- "Estimate capital stock (perpetual inventory)"
- "Estimate TFP trend (HP filter or Kalman filter)"
- "Combine using Cobb-Douglas function"
