Abstract
The estimation of output supply and inputs demand in farming sector with the assumption of full economic efficiency may result in false policy decisions. This article investigates the effects of irrigated wheat economic inefficiency on output supply and inputs demand in the period 2001-2009. After estimating the economic inefficiency by the use of production and cost stochastic models, the output supply and inputs demand of irrigated wheat are obtained through seemingly unrelated regression method. Results show that technical, allocative and economic inefficiency in irrigated wheat production in Iran are 21, 23 and 38 percent respectively. Moreover, the slope of output supply function is strongly affected by the related economic inefficiency in profit function and inefficiency changes input’s demand coefficients. Results also show that technical inefficiency has a greater effect on inputs demand compared to the allocative inefficiency.

Abstract
Legal and economic dimensions of sanctions, and also its diversity make it difficult to evaluate the contribution of the sanctions on macroeconomic variables; besides quantification of sanction by itself is a major problem. As the first step in this study, we try to offer a new index for representing the sanction in economic modeling. For this purpose by applying the exploratory factor analysis approach, we try to measure the mentioned index and produce the time series for the period of 1978-2010; here twelve variables which are mainly affected by the sanctions included in related process. Then, applying three-stage least squares (3SLS) method for a small macroeconomic model, the contribution of the sanctions on major economic variables such as economic growth, trade, investment and employment are evaluated. According to the findings of this study, the direct effects of sanctions are only significant in growth and term of trade equations. It seems also that there is a direct relationship between severity of the sanctions and its impact on major economic variables.
