中文摘要
相較於硬性資訊,軟性資訊容許資訊蒐集者更多詮釋、操弄資訊的自由。但 Baliga (1999) 的分析顯示,當負責蒐集資訊的監督人可能與代理人勾結時,委託人所得到的利潤不因資訊性質為硬性資 訊或軟性資訊而改變。本文從數個觀點驗證這個等價結果是否仍然成立,包括引進不同資訊蒐集技術、允許代理人的保留價格隨其私有資訊變異、以及考慮監督人的事業誘因等等。本文同時發現監督人的事業誘因可能加重或減緩組織內的勾結問題。而當事業誘因加深勾結問題時,委託人不會對未來雇主充分揭露監督人的工作表 現,使得未來雇主無法雇用最有能力的監督人。亦即,勾結問題可能產生就業市場上的資訊摩擦。
Abstract
This study takes a closer look into the equivalence result of Baliga (1999) namely, that a principal obtains the same optimal collusion-proof payoff for both hard and soft information. In the procurement model of Baliga (1999), we consider the sensitivity of equivalence to monitoring technologies, the agent's type-dependent reservation utility, and the supervisor's career concerns. We also show that career concerns may exacerbate the collusion problem. In response, the principal refrains from fully revealing the supervisor's performance to the future employer, hence generating informational frictions in the labor market.
