Profit, Expectations and Coherence in Economic Systems

Abstract

Professor Shackle is the most courteous, the most erudite, and the most radical critic of orthodox economics. The concept of profit, which apparently serves as such a convenient instrument of equilibrium, on closer enquiry is revealed to be necessarily subversive of such schemes of order; for profit can arise only where knowledge is not adequate to support any agreed — even probabilistically agreed — assessment of a situation. Thus any consideration of Professor Shackle's (1972, Chapter 35) discussion of profit focuses our attention on the insufficiency of knowledge which is the core of his criticism of orthodoxy. It should be no surprise, therefore, to find that the problem of coherence within economic systems resembles the problem of coherence in the growth of knowledge. Both appear to depend upon a productive but precarious tension between imaginative conjectures and a framework of serviceable conventions within which they may be tested.
