    Abstract:   在古典理性預期模型中,理性的投資者會蒐集並利用各種相關訊息來幫助其做最適的投資行為。然而市場價格也是訊息來源之一。在效率市場中,價格完全透露出訊息,則無人會有蒐集訊息的動機;若市場有干擾,價格無法顯露出所有相關訊息,私人訊息便有價值。因此,價格資訊性的高低,會影響到私人訊息對投資的重要性。其次,訊息若要能幫助投資者獲得套利利潤,仍須假設投資者必須能夠持有資產一直至資產價值實現為止。顯然的,短期投資者並不符合此一假設。我們相信在通常情況下,長期投資者會比短期投資者更有動機去成為消息靈通者,而且短期投資者對訊息處理的態度有許多特性迴異於古典模型的投資者,他們的存在對市場價格資訊性也會有相當程度的衝擊。本文基於上述想法,利用干擾不對稱訊息下之多期理性預期模型,假設市場中有長期與短期投資者,來探討影響價格資訊性之各項因素及短期投資者之行為特性。
