Consumption expenditures is one significant component of aggregate demand. As opposed to lifetime income and permanent income hypothesises based on Ricardian policies, recent theoretical and empirical studies indicate possible fiscal impacts on household consumption decisions. Besides providing insights to determinants of consumption decisions, these studies also guide to policy solutions to high and risky current account deficits and high and persisting inflation rate problems. This empirical study for Turkey is another attempt to distinguish any non Ricardian policy and search for possible fiscal policy effects on household consumption decisions. Allowing for long run and short run effects indicates that the expentionary Keynesian impact of fiscal policy on household consumption is significant only if fiscal policy is sustainable.
