Abstract
We investigate the nature of power corrections and infrared renormalon singularities in large-β0 approximation. We argue that the power correction associated with a renormalon pole singularity should appear at O(1), in contrast to the renormalon ambiguity appearing at O(1/β0), and give an explanation why the leading order renormalon singularities are generically poles.
