Abstract
The objective of this paper is to investigate the validity of Wagner’s law and the Keynesian view with regards to the relationship between the non-oil gross domestic product and the public sector size for the Iranian economy during the period of 1967-2007. Time series analysis techniques have been used which include unit root tests, cointegration tests and Hsiao causality test. The findings indicate that Wagner’s Law is confirmed in both the short-run and the long-run; whereas the Keynesian view is approved only in the short-run for Iran.

Abstract
Exacerbating income inequality and increasing crimes give rise to waste of human and financial resources of the society. However, causality direction between income inequality and crime remains a controversial issue. Applying Hsiao’s causality test for the 1984-2014 period, this study examines the direction of causality between these social problems in Iran. The crimes under study include crimes against property (embezzlement, bribery, forgery, theft and bounced checks) and violent crimes (murder, battery, duress and harassment). In addition, Gini coefficient is used as an inequality index. The optimal lag lengths are one for crimes against property and two for violent crimes, respectively. Findings indicate significant bidirectional causal relationships between income inequality and two kinds of crimes.
