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.
