[edit] MRS

Not only might the utility function not be smooth, it might not correspond to a measure at all. A pervasive problem with economics articles on Wikipedia is that the are written by editors who are only familiar with works in the Bentham-Jevons-Marshall tradition. But see “The Austrian Theory of the Marginal Use and of Ordinal Marginal Utility” by J. Huston McCulloch in Zeitschrift für Nationalökonomie 37 (1973) for a mathematically formal treatment of MRS where utility cannot be fit to any measure. —SlamDiego 06:24, 24 April 2007 (UTC)
