We show that a natural rate of growth is a solution of the equation y =f(y); hence its endogeneity to y requires the unlikely case that more than one solution exists, the shift within the set of solutions being determined by y. Léon-Ledesma and Thirlwall (2000a and b), attempting to investigate empirically the endogeneity of the natural rate, set up a procedure by which their OLS estimate of the natural rate produce two levels, the higher corresponding to the group of observations with higher y. But we prove their (widely replicated) procedure is seriously flawed, because an important variable is not statistically exogenous and most probably , according to our simulations, its coefficient is close to zero.
