It's not just about the future: The present payoffs to behaviour vary in degree and kind between the rich and the poor.

Pepper & Nettle offer a nuanced and humane view on poverty that should be required reading for policy makers, particularly those interested in "behaviour change" policy. We suggest, however, that the emphasis on "future-discounting" in this paper downplays the importance of differences in the payoffs to behaviours in the present and how these payoffs may be realised in different currencies.
