In the present study, the effects of increasing the value of shale gas production, either due to increased production or price increases, have been studied on economic variables such as employment, wage, property value and the number of births. In this regard, the data for each of these variables was used at the county level in the United States of America between 2000 and 2011. In order to estimate the desired effects, counties are divided into two types of boom and non-boom counties. The findings indicate that increasing natural gas production will lead to more employment and wage growth in boom counties than non-boom counties. Also, during the period of increasing production, the value of... 

In this study, we estimate the effect of overeducation on the gender pay gap in the private and public sectors, using Household Expenditure and Income Data of 1396. For this purpose, the realized matching method is used to calculate the overeducation and the Oaxaca and Blinder decomposition model to calculate wage gap. The results show that being female in both the private and public sectors has a negative effect on wages, but this effect is much stronger in the private sector. We also find that the gender wage gap among overeducated is lower than propereducated. The gender pay gap and its unexplained componentin among overeducated worker in both sectors is less than propereducated worker.... 

In this study, the intensity of child labor has been investigated by modeling household behavior in a framework of collective decision-making on resource allocation, and for this purpose, a household utility maximization problem has been used in which child’s and parents’ wages, non-working incomes, education level for bargaining power as well as several variables at the social level such as unemployment rate, divorce rate and Gini coefficient have been used to reflect labor market conditions. In this study, the structure of equations for girls and boys in urban and rural areas has been estimated by using raw household budget data for 2015 in Iran and multivariate Tobit technique. Findings... 

This thesis presents significant findings relevant to the transportation industry, focusing on the factors influencing drivers' inclination towards seeking higher payment. The study also proposes potential strategies to enhance driver satisfaction and retention. The research examines the elements that affect drivers' inclination to request higher wages when confronted with challenging work scenarios. Data from Iranian heavy vehicle drivers were collected using a structured questionnaire, which assessed their willingness to receive higher wages under unfavorable conditions such as mountain roads, hot and muddy weather, additional stops during the trip, and extended periods away from home. The...
