Economists' Views about Parameters, Values, and Policies: Survey Results in Labor and Public Economics
调查40所顶尖大学的经济学家，发现他们对政策的立场与价值观关系更密切，而非参数估计；个体估计差异大但置信区间窄。
Specialists in labor economics and public economics at 40 leading research universities provided opinions of policy proposals, quantitative best estimates and 95-percent confidence intervals for economic parameters, and answers to values questions regarding income redistribution, efficiency versus equity, and individual versus social responsibility. Their positions on policy are more closely related to their values than to their estimates of relevant economic parameters. Average best estimates of the economic parameters agree well with the relevant literature, but individual best estimates are usually widely dispersed. The individual 95-percent confidence intervals are much narrower than the substantial cross-respondent variation in estimates would warrant.
