了解學生願意支付多少金額以換取較好成績的問題，對於教育的公共政策及學校教育的私人報酬有重要的含意。但從未有實証研究學期成績的價值以及對於學生的重要性。我們引進市場機能評估成績價格的方法，讓學生能表達對成績的偏好。換言之，能顯現出學生對成績願意支付的價格(影子價格)。實驗顯示，公共經濟學的學期成績，平均每分價格為66.7元。此外，我們發現即使不存在市場交易的成績，學生仍具理性行為，符合經濟理論之命題。 The question of how much individuals would pay for better academic performance is a useful one that has important implications both for public policies toward education and for understanding the private returns to schooling. However, there has never been any empirical study to investigate the values of the academic performance and how important the grades are in terms of reflecting students’ academic performance in schools. We introduce a market for the academic scores and develop a price mechanism to reflect the students’ preference for the academic results. In this experiment, the average bidding price (shadow price) per point of the public economics is NT$66.7. The results show that the students’ behavior is rational, and complied with the economic theory.
