再探討面試日期選擇──考慮配對大學金融系的先天差異

Revisiting Interview Date Selection-Considering Innate Differences in Finance Departments of Matched Pair University

本文比較配對大學金融系的招生績效表現，試圖釐清不同面試日期選擇是否成為影響配對大學金融系招生績效的重要因素？首先，本文計算配對大學金融系於102-105學年度以及106-109學年度在正確篩選率、備取率、及分發率的表現；然後，比較檢驗這兩個時期的表現是否有顯著差異。本文發現如下：86%的配對大學金融系的比較結果證實較晚面試會有較高正確篩選率；同樣地，86%的配對比較結果亦證實較晚面試有較高的分發率；以及沒有任何配對比較結果證實較晚面試有較低的備取率。據此發現，本文宣稱在控制了配對大學金融系的先天差異影響後，任何大學金融系若選擇較晚面試，將可以獲得好處（較高正確篩選率及分發率）而且不必付出額外代價（較低備取率）。

This paper compares the enrollment performance in the finance departments of matched pair university, and tries to clarify whether the selection of different interview dates is an important factor affecting such enrollment performance. First, we calculate the performance in terms of the correct selection rate, the reserve rate, and the distribution rate in the 102-105 academic years and the 106-109 academic years for the finance departments of the matched pair university; then, compare the performance of the two periods to see if there is a significant difference. The findings of this paper are as follows: 86% of the matched pair-comparisons confirm that later interviews have a higher correct selection rate; similarly, 86% of matched pair-comparisons also confirm that later interviews have a higher distribution rate; and none of the pair-wise comparisons confirmed that later interviews had lower reserve rate. Based on this finding, this paper claims that after controlling for the effect of innate differences in the finance departments of the matched pair university, any university finance department who chooses to interview later will gain benefits (higher correct selection rate and distribution rate) and without paying additional costs (low reserve rate).
