Abstract
This study explores how monetary and fiscal policies influence certain macroeconomic variables through a multi-sector stochastic dynamic general equilibrium (DSGE) model that includes input-output (IO) analysis. The focus is on the industrial sector, taking into account the specific conditions for Iran. The research uses quarterly data from Spring 2006 to Spring 2023 and references the 2016 input-output table provided by the Central Bank. In the nonlinear model, the original 89 activities from the input-output table have been simplified to 9, which includes the industrial sector and eight other sectors. Model parameters are estimated based on previous studies of the Iranian economy and data from the input-output table. The model's effectiveness is assessed by comparing simulation results with real-world data, which shows a strong correlation. The simulations indicate that increases in the money supply result in only a small rise in both total and industrial output. This leads to a slight decrease in total employment, while employment in the industrial sector experiences a minor increase. Similarly, increases in government spending show tiny improvements in overall and industrial output, accompanied by a slight drop in total employment and a small rise in the industrial sector. The findings suggest that the effects of monetary and fiscal policy shocks on output and employment, when accounting for input-output relationships and dividing the economy into nine sectors, better reflect the realities of the Iranian economy. Given the minimal influence of these policies on boosting production and economic growth, it is essential for them to be targeted and supported by additional measures and strategies.

Abstract
One of the most important goals of policymakers is to increase the rate of economic growth while keeping the environment clean, which is possible through the use of modern technologies and the influx of capital into the country. Foreign direct investment (FDI) is an important source for promoting energy-efficient technologies around the world. One of the most important issues in today's world, especially in developing countries, including Iran, is securing the necessary capital to advance economic and environmental goals. For this reason, the present study examines the effects of foreign direct investment on macroeconomic and environmental variables using a computable general equilibrium static model. Two scenarios have been analyzed and examined as the effects of a doubling of FDI, one on the electricity sector and the other on the entire economy. The results showed that in both scenarios, economic growth increased and the general level of prices decreased, but the effect was greater in the second scenario. Electricity production also increased in both scenarios. But household welfare has decreased with increasing foreign direct investment. In the carbon emission variable, the pollution halo hypothesis is confirmed in the first scenario, and the pollution haven hypothesis is confirmed in the second scenario. It is suggested that the government, in addition to providing domestic platforms for the entry of foreign capital, also pay due attention to domestic capital owners.
