Shrouded Attributes and Information Suppression: Evidence from the Field
通过在线拍卖的实地和自然实验，研究运费披露与水平变化对收入的影响，发现低运费时披露更有利，隐藏时提高运费可增加收入。
We use field and natural experiments in online auctions to study the revenue effect of varying the level and disclosure of shipping charges. Our main findings are (1) disclosure affects revenues-for low shipping charges, a seller is better off disclosing; and (2) increasing shipping charges boosts revenues when these charges are hidden. These results are not explained by changes in the number of bidders. (c) 2010 by the President and Fellows of Harvard College and the Massachusetts Institute of Technology..
