Wagner's Law and public expenditure in Iraq: A test using disaggregated data

Abstract

Recent developments in time series analysis have encouraged economists to re-examine the validity of Wagner's Law. Recent econometric tests have shown mixed results with some upholding the hypothesis while others contradict it. Carrying out econometric work with aggregated data could account for this. This study using disaggregated data measured in both real and nominal terms also leads to contradictory results.
