We develop a decision framework with imperfect information to analyze the effects
of transaction costs on the tendency for individuals to remain with a default option.
We demonstrate how transaction costs can be a more important source of such default
effects than commonly thought. A further, potentially surprising result shows that
transaction costs are able to explain why some forms of default effects increase with
the number of options.

Keywords Default effect; transaction cost; imperfect information.
