Formula and method
Assumptions and limitations
Parameters must be estimated externally; this model is not a measured firm productivity or national forecast.
Worked example
With productivity factor a = 1, capital input k = 100, labor input l = 100, capital elasticity = 0.3, labor elasticity = 0.7, modeled output is approximately 100.
