If the future were known with certainty, then the economic implications of Cap and Share would equal the economic implications of a carbon tax with lump sum recycling—that is, the carbon tax revenue would be used to send every household a cheque in the post. Some argue that lump sum recycling is an inferior way to recycle the revenue of environmental taxes, and that this has been repeatedly confirmed for Ireland.
If the future were known precisely, then Cap and Share's economic outcomes would mirror those of a carbon tax with lump sum redistribution—meaning the tax revenues would be sent to every household as a check. Some argue that lump sum distribution is an inferior way to handle environmental taxes' revenue, which has been demonstrated in Ireland.
