The aim of this study is to investigate the short-run asymmetric effect of the gini coefficient, unemployment and divorce on the prior period robbery, using error correction smooth transition model. This study using annual data (1363-1389). For this purpose, at first we investigate data constant and long-run relationship using Engel and Granger hypothesis. The results show that non-linear model has higher explanatory power than the linear model, So that the change in the gini coefficient and unemployment of prior periods on the current period's robbery in middle and high threshold for both variables have the greatest effect. In divorce cases, according to the results of the three threshold has a effect impact on robbery. However, in high threshold it has the greatest effect.
