Demand-side Models of Short-term Income Formation
The chapter discusses different formulations of the main behavioural equations for private consumption, investments, and money demand that are used in the advanced economies for building a short-term Keynesian aggregate demand model, and the IS-LM, AS-AD, and Mundell–Fleming models. These models are used to study the formation of the level of income over the short term in the advanced countries, under both open and closed economy conditions. As such, these models allow us to study the fluctuations of the level of income over the short term due to exogenous factors or policy shocks, for example expansionary or contractionary fiscal policies, monetary and wage policies, or changes in consumer and investor expectations. The chapter identifies the conditions implicit in such models for the success of expansionary policies in advanced countries.
