In recent years, a handful of vocal conservatives have been arguing that a carbon “tax swap deal”—where new revenues from a carbon tax are used dollar-for-dollar to reduce existing taxes—could provide a win-win, both mitigating climate change and even boosting conventional economic growth. I wrote an entire study for IER debunking this case, but in the present post I want to quote from a recent survey journal article to show just how dubious the alleged “double dividend” from a carbon tax truly is.
