The analysis will be conducted within an IS-LM model augmented by the dynamics of money wages, private capital and public debt. A macroeconomic shock induces an extended process of adjustment that is characterized by unemployment. This in turn requires a dynamic path of monetary and fiscal policy: As a response to the shock, the central bank continuously adapts the quantity of money so as to keep up full employment all the time.
