Ljungqvist and Wilhelm (2002)己證實了在初次公開發行市場,限制承銷商的配售裁量權會減少詢價圈購階段資訊的產生,以致於妨礙最終發行價格相對於訂價範圍的修正幅度。比較美國的詢價圈購制度,台灣與香港在初次公開發行市場採用詢價圈購與公開申購同時進行的雙軌制,有更多關於訂價及配售的法規限制,但是台灣與香港的價格修正幅度卻明顯高於美國,看似於Ljungqvist and Wilhelm (2002)的結果互為矛盾。本論文認為台灣與香港價格修正幅度顯著較高這個現象,並非資訊產生增加了,而是初級市場價格發現的無效率,迫使價格發現機制於次級市場進行,此時若以迴歸模式比較三個市場之間的價格修正與折價(underpricing)關係,不是單純的「部份調整效果」,而是混合了初級市場相對於次級市場價格發現效率的效果。為了解決台灣、香港、美國之間,價格修正與折價關係的內生性差異,本論文採用變異數比率(variance ratios)可證明在初次公開發行市場限制愈多,對價格發現效率愈不利,並無與Ljungqvist and Wilhelm (2002)的實證互為矛盾,台灣與香港的情況亦然。
It has been proven by Ljungqvist and Wilhelm (2002) that constraints on underwriters’ allocation discretion reduce price revisions. The dual-tranche of IPO bookbuilding in Taiwan and Hong Kong impose more regulatory constraints limiting underwriters than U.S. bookbuilding does, but price revisions of Taiwan and Hong Kong IPOs are significantly higher than those in the U.S. This is due not to increased information production but to the price discovery inefficiency in primary markets. Price discovery inefficiency in primary markets compels price discovery in secondary markets, then the underpricing is not a pure “partial adjustment” effect. Due to the endogenous heterogeneity of price revisions related to underpricing among Taiwan, Hong Kong and the U.S., this dissertation uses the variance ratios to prove the empirical evidence in Taiwan and Hong Kong is not contradictory to that of Ljungqvist and Wilhelm (2002).
