By building upon Raz's analysis of the spectrum of voluntary obligations, the author produces a typology of agreements, and then assesses the extent to which these different kinds of agreements underpin the common law of contract. While recognizing that the law of contract purports to deal with a broad range of voluntarily undertaken obligations, the typology of agreements suggests that the present law is primarily suited to dealing only with bargains. This suggests that there are situations in which agreements should (...) be legally recognized, but which should not be dealt with by all of the conceptual tools of contract law, for these agreements and voluntary undertakings serve the interests of those undertaking them in significantly different ways than do bargains.
