美国两位经济学家尤里·格尼茨和约翰·李斯特一直在考虑一个问题:怎么样改善孩子的学习成绩?方法有很多种,比如内在激励:孩子,爸妈省吃俭用供你读书,你一定要争气……这些方法往往不管用。后来,他们想到一个离经叛道的办法,拿钱奖励他们。不过值得一提的是,经济学家开展实验的地方是美国高地市170学区,这里的孩子学习很差,家境也不好。 Two U.S. economists, Uri Geniz and John Lister, have been asking the question of how to improve their child’s academic performance. There are many ways to do this, such as the intrinsic motivation: Your children and parents live frugally for you Reading, you must strive ... these methods often do not work. Later, they thought of an outrageous way, rewarding them with money. However, it is worth mentioning that economists conduct experiments in 170 high school districts in the United States, where children learn poorly and have poor family circumstances.
