摘要
Andersen and Jordan （1968） aimed to measure efficiency of monetary and fiscal actions on real GDP by employing a time-series model which was called as St. Louis Model afterwards. Although the model is performed in many countries similarly, the results differ from each other in accordance with the economic structure of relevant country In this regard, the aim of this paper is to investigate the effectiveness of monetary and fiscal policies on real activity and to find out causal relationship among questioned variables using OLS and causality methodologies in Turkish economy over the period 1998：1-2010： IV. Empirical findings indicate that only monetary policy has a significant positive effect on economic activity in the short run, Nonetheless, neither monetary nor fiscal policy has significant impact on real output in the long run. Causality analysis shows that there exists a unidirectional causality running from real output and money stock to government expenditures. Moreover, not surprisingly, it is also found that crisis experiences of Turkey in sample period have highly adverse impact on real activity. Causality analysis suggests us considering government expenditures as explained variable instead of real output. Hence, it can be concluded that St. Louis Model total spending equation is not applicable for Turkish economy during 1998-2010 periods
