Additional Steps to ECM and ARDL

Ednaldo Silva’s blog dated August 21, 2025, contains three sequential equations about the profit rate. My purpose is to demonstrate the connection between his logarithmic 2nd equation and the 3rd equation, referencing the ECM and ARDL econometric models. I used the same econometric reference he cited and adopted some notations of the textbook by Dimitrios Asteriou and Stephen Hall.
