What is important for the paper is that the above analysis shows how intrinsically connected are the ideas of barter, money neutrality, “real” economic analysis, “exogenous money,” inflation, money scarcity, and “loanable funds theory.” These theoretical tools then allow the orthodox economists to conduct “correct” monetary and fiscal policies. To recapitulate, monetary policy determines price levels while fiscal policy negatively affects private investment. Hence, the solution is to target a stable money supply and to run balanced government budget as long as possible. It is therefore that the myth of barter is crucial in the orthodox theorizing.
