These lectures will explain how government manipulation of the money supply causes the business cycle. Discussion will include: how faster growth of the money supply temporarily causes rising national employment, production, and income; why faster growth of the money supply eventually must raise the rate of price inflation; why the effect on prices takes longer than the effect on employment and how this makes the business cycle politically expedient; how rising prices reveal bad investments; how slowing down the growth of the money supply causes recessions; the two ways to recover from a recession and why politicians consistently choose the wrong one.
