Ronald J. Mann and Travis Siebeneicher's Working Paper, "Just One Click: The Reality of Internet Retail Contracting," can be read at: http://ssrn.com/abstract=988788. Here's the abstract:
Scholars for decades have noted the possibility that
standard-form contracts disadvantage consumers. For many years,
that literature focused on the idea that sellers with market
power draft contracts that are disadvantageous to consumers. Law
and economics scholars, however, have been skeptical about that
hypothesis, pointing out that a strategy of inefficient terms
rarely would be the optimal technique for exploiting market
power. In recent years, however, the debate has shifted as new
product distribution channels have changed the technology of
contracting. Now, even firms without market power can exploit the
cognitive failures of their customers through ?shrouding? of
terms and similar techniques.
That concern has become more prominent with the rise of Internet
retailing, where electronic standard-form contracts are used
extensively, often undermining the notion of assent on which the
contract paradigm traditionally depends. Scholars have worried
that Internet retailers obscure one-sided terms so that customers
will continue to shop at their sites, and do so more effectively
than their brick-and-mortar counterparts. This, among other
concerns, has led many to argue for a new contracting regime that
deals with electronic contracting. Indeed, because software is
often distributed online, this is a major topic in the ALI's
current project on Principles of the Law of Software Contracts.
