There is evidence that people discount food more steeply than money, suggestingthat primary or consumable reinforcers lose value quickly, whereas conditionedor nonconsumable reinforcers lose value slowly. In the present study,discounting rates of baht (unstable currency) and rice (preservable food) werecompared during a period of unstable economic conditions in Thailand. Delaydiscounting of 2 amounts of hypothetical money and 2 matched amounts ofhypothetical rice were examined. For smaller amounts of rewards, there was no difference in rates of discounting between money and a matched amount of rice. For larger amounts of rewards, however, money was discounted more steeply than a matched amount of rice. It was suggested that the unstable currency might be discounted more severely than a durable good of comparable monetary value in some circumstances.
