Solow Residual referring, correct, returns, someone

cfalevel2011

When constant returns to scale are assumed, the Solow Residual is 0.

Is this statement correct?

Can someone explain the equations how the constant returns to scale affects it?


This is the formula i'm referring to:


% delta Y = % delta Solow Residual + (a) * % delta K + (1-a) * % delta L
