Rao suggests that the Rowan demand curve does not exist but that result is obtained through treating the system as a simultaneous equation problem that will inevitably obtain the standard aggregate demand (AD) result. The Rowan procedure is a conditional function that makes planned AD conditional on planned aggregate supply (AS)—a quintessential Keynesian process. This results in an AS-dependent AD curve that is upward sloping. This system can be shown to be stable, have a firm connection to measures of national income accounting without dependence on notions of equilibrium and implications for econometric estimations.
Key Words: Keynesian and neo-Classical model Aggregate demand and supply
