This paper offers an extension of the distinction of [Kohn, Cato Journal,
24:303339 (2004)] between the two paradigms of modern economic theory,value and
exchange¿as derived from the generic¿operant framework of [Dopfer and Potts, The
general theory of economic evolution, Routledge, London, (2007)]. I argue that Austrian
and evolutionary economics can be analytically unified about a general framework of rule
coordination and change that I shall call the generic value paradigm. This is an analytic
generalization of Kohns exchange paradigm that will allow us to redefine his conception
of the value paradigm as the operational value paradigm in terms of the economics of
known and fully exploited opportunities
