'That is an allocative devise in market economies involving the forces of demand and <br/><br/>supply in determining prices and outputs' <br/><br/><br/> What I don't understand in this sentence is the word 'allocative' is it an adjective? <br/><br/>adverb? and what does it mean? what happens if you add a '-ive' ending to a verb? <br/><br/>Thanx guys
