Calculus attainment and grades received in intermediate economic theory
用贝叶斯方法重新检验数学基础对中级经济理论课程成绩的影响，发现微积分水平对中级微观经济学成绩有重要解释作用。
Abstract We revisit the work of Butler et al. ( 1998 ) who examine the effect of mathematical preparation on grades received in intermediate economic theory courses. Using a Bayesian approach under reasonably ‘diffuse’ priors, we are able to replicate their two‐step point estimates almost exactly. We also introduce a new model specification that accounts for the censoring and discrete nature of the outcome variable (grade received). The results from this specification echo the conclusions of the original paper—the level of calculus attained plays an important role in explaining grades received in intermediate micro theory.
