“…According to some theories, bank behaviour can influence changes in macroeconomic variables such as credit, interest rates, money supply, savings and investment -for instance, Wignall and Gizycki (1992), (effect on credit supply and demand), Mills, Morling and Tease (1993), (the effect on corporate funding), Battelino and McMillen (1989), Fahrer and Rohling (1990), (monetary policy), Coombes (1995), (price stability), OECD (1991), (patterns of bank lending and effects on consumption and saving). Hence if those variables change this is taken as indicative of the effectiveness of policy change.…”
