No, not for these types of offences, and that's borne out by the criminological evidence. If you're acting out of desperation, out of poverty, or if you just don't give a damn, the minimum sentences or the length of a sentence doesn't deter crime.
Where they might is when you have people engaged in complex cost-benefit analysis, but we hardly ever see anyone propose minimum sentences for large corporate crimes or greed in corporations. It might have an impact there, but certainly not in these types of offences.
