Oil prices and their uncertainties significantly impact the economies and financial markets of nations, influencing the cash reserves held by companies. Given the pivotal role of the chemical products industry has an important role in economic development and is also affected by other markets such as the oil market, this study aims to to investigate the effect of Brent oil price uncertainty on the cash holding of the chemical products group in the Tehran Stock Exchange during the period of 2010-2019. The research modeling is based on dynamic panel models and oil price uncertainty is computed through the GARCH method, while the relationships between variables are estimated using the Generalized method of moments (GMM) technique in two steps. The results of the study indicate that there is a positive and significant relationship between oil price uncertainty and cash holdings during the period under review. In addition, the effect of control variables such as financial leverage, cash flow, size, capital expenditures, liquidity, stock return, and return of assets is positive, and the effect of total debt, value added of industry, and interest rates on the cash is negative.

Married men are one of the main groups of labor market employed and therefore the study of their labor market behavior is one of the priorities of labor market policy. The present study attempts to identify the variables affecting the market working hours of married men with employed spouses based on the literature of the collective model (CM) of household labor supply. The research information is based on micro and cross-sectional data of Iran in 2018 and the statistical sample includes 724 married men living in urban and rural areas. The model was estimated using the generalized method of moments (GMM) and related tests. The results show that the labor supply function of married men is standard (the substitution effect is larger than the income effect) and the supply increases with wage but at diminishing rate. Also, married men with higher levels of education than their wives spend more leisure-living time. Also, working hours of married men with employed spouses decrease with age. Moreover, higher education and number of children increase married men working hours.
