Unemployment rate is one of the most leading among the important economic indicators. One of the most influential factors on unemployment rate is job quitting. Experts consider two kinds of job quitting, intentionally and unintentionally. Many studies have been done around the world, on the importance of job quitting, unemployment duration, and also on the costs caused by finding a new job. But, no one has studied job quitting and its impact on the unemployment rate in Iran, while this survey, besides all mentioned phoneme phenomenon, has also paid attention to the relationship between job quitting by wage earning and entrepreneur, intentionally and unintentionally, using the issued data of 2006 in the country.
The results of this survey, using the Probit Model, shows that intentionally factors like low income, family problems and immigration, have a direct impact on job quitting by self employed. While other intentional factors like keeping on the studies, and unintentional factors like, having a seasonal job, firing or cutting down the number of personals, retiring, and end of conscription have an indirect impact on job quitting by self employed.
