Systematically Biased Beliefs about Economics: Robust Evidence of Judgemental Anomalies from the Survey of Americans and Economists on the Economy
利用美国人与经济学家经济调查数据，检验公众与经济学家在经济观点上的系统性分歧，发现这种分歧并非源于经济学家的自利偏见，也不受政治意识形态影响，且经济训练的作用在控制教育后仍显著，表明判断异常真实存在。
Differences between the general public"s "positive" economic views and economists" resemble other judgemental anomalies: Laypeople and experts "systematically" disagree. I analyse this puzzle using data from the Survey of Americans and Economists on the Economy. The paper first tests and decisively rejects the hypothesis that the differences solely reflect economists" self-serving bias. Then it examines whether economists" political ideology and party loyalties explain the disagreement; if anything, this slightly increases their magnitude. The effect of economic training clearly falls but remains large after adding education to the set of control variables. Apparent biases" robustness suggests that the anomaly is real.
