Nowadays explaining the behavior of household members is not considered as a neglected black box, and interactions between household members, can influence household consumption, employment and thus its welfare. Applying unitary model, the goal of this research is to estimate and study labor supply functions of dual-earner couples who have non-labor income, using Iranian rural-urban families' cost-expenditure data in year 2013. Supposing wage variable is endogenous, the estimation procedure is based on generalized method of moments. Our findings show that in the pattern of married women's labor supply, inverse of Mill's ratio is negative and statistically significant. So, computing this variable by Heckman's Two Step Model results in consistency of results. The elasticity of own wage labor supply of both couples is positive and statistically significant. From this point of view, the couple's labor supply curve, in studied sample, has standard shape. Studying cross wage elasticity, shows that couples' leisure time are complementary. In line with theoretical base, a rise in non-labor income has negative and statistically significant effect on couples' labor supply hours.

The purpose of this study is to investigate the determinants of inflation in the period 1960-2011 and autoregressive model (VAR) is used here. In this study due to the structure of the Iranian economy, the mark-up index is derived and its growth growth along with liquidity growth, nominal exchange rate growth and productivity growth are used in the model. The results of Granger causality test show one-way causal relationship between the three variables of mark-up growth, exchange rates growth and labor productivity growth in one hand and inflation on the other hand, as well as two-way causal relationship between money growth and inflation. Also impuls response functions confirm a negative relationship between labor productivity growth and inflation. Moreover, based on the analysis of impulse response functions of three variables of mark-up growth, liquidity growth and exchange rate growth, they are positively correlated with inflation. Variance decomposition showed that each of the variables of inflation, mark-up growth and labor productivity growth in the short-term and respectively with the shares of 45, 29 and 25 percent, have the highest explanation on inflation forecast variance. But in the long run, the effect of mark-up growth is reduced, and labor productivity growth, inflation, liquidity growth, exchange rate growth and mark-up respectively explain 30, 28, 17, 14 and 10 percents of the forecast errors.
