The traditional treatment of monetary policy assumed that central banks chose the money supply and then let the interest rate adjust. Now however, central banks choose the interest rate and then let the money supply adjust. In terms of the IS-LM model used to describe the short run, the LM curve, instead of being upward sloping, should be treated as flat. This makes for a more realistic and a simpler model (Chapter 5). Focus on the role of the financial system in the economy. The text extends the IS-LM model to allow for two interest rates—the interest rate set by monetary policy and the cost of borrowing for people or firms, with the state of the financial system determining the relation between the two (Chapter 6). An IS-LM-PC (Phillips curve) model replaces the traditional aggregate supply and aggregate demand model, and gives a simpler and more accurate description of the role of monetary policy and of output and inflation dynamics (Chapter 9). Coverage of the constraints on monetary policy, coming from the zero lower bound, and the constraints on fiscal policy, coming from the high levels of public debt, has been added. UPDATED!
