%0 Journal Article %T Animal spirits: Keynes' theory of rational investment decision-making under conditions of fundamental uncertainty %A Radonji£¿ Ognjen %J Theoria, Beograd %D 2009 %I Serbian Philosophical Society, Belgrade %R 10.2298/theo0901017r %X Keynes's term, animal spirits, has been mistakenly confused with irrational decision-making. However, if we accept Keynes' assumption that future is fundamentally uncertain and nonergodic, animal spirits become key factor that makes continual process of investment decision-making possible. On the other hand, if animal spirits blunt, investment activity dwindles and makes emergence of deep economic crisis likely. %K risk %K uncertainty %K investments %K conventional decision-making %K animal spirits %U http://www.doiserbia.nb.rs/img/doi/0351-2274/2009/0351-22740901017R.pdf
