The IMF reports that, over 60% of foreign trade income and 40% of government revenue of Iran comes from the oil and gas sectors, which has always been a source of volatilities in the economy. The imposed sanctions on the Iranian economy also influence economic activities by reducing currency earnings and restricting access to capital and intermediaries goods. Understanding extent of the shocks’ effects of sanctions and fluctuations in oil revenue, are key factors for the policymakers in foreseeable planning risks. In order to examine the effect of sanctions and oil price(revenue) fluctuations on the country's economy, this paper intends to quantify the effects of sanction by making use of a VARMAX GARCH-in-Mean Asymmetric BEKK model in terms of structural failure of the conditional variance. We use real non-oil GDP, Iranian heavy oil exports, exchange rates, total stock market index and sanctions index data over 1991:Q2 to 2018:Q1. The results show that a shock of oil revenue or sanctions index affects activities in all of three sectors. The increasing sanctions pressure leads to a spillover effect of uncertainty to all sectors under study and a decline in production activities and national currency depreciations; but in turn the relative share of the stock market in the portfolio of investors' choice increases. Strong evidence for asymmetric effects of impulses of sanction and oil revenue on the study sections is observed.

As the driving force behind economic growth in the world markets, export is the most significant objective of foreign trade policy. One of the requirements for expanding foreign trade is to examine modern models of international trade to identify the economic and political issues affecting the countries’ trade. For boosting economic growth, the majority of countries seek to expand trade with other countries, producing goods and commodities based on relative advantages. Various factors may affect the values of Iran’s exports to other countries, among which the leading institutional indicators, which are capable of providing suitable conditions for expanding the export markets of Iran, seem to be highly significant. In the present paper, the effect of political institutions on Iran's exports to West Asian countries during the period 2000-2015 is investigated and empirically analyzed by mixed regressive-spatial autoregressive model. The research employs a regression model with panel data based on different commodity groups in the six-digit codes of Iranian trade with West Asian countries. As the research findings show, the governance index, representing the political institutions, has positive and significant effects on exports and significantly affects Iran's exports.

Input-Output Table (IOT) analysis is important especially concerning trade, environments, productivity for planning and policy making. Quality of the analyses depends on the estimation of Symmetric Input-Output Tables (SIOT) and also the use of the types of technology assumption (Product Technology versus Activity Technology). The choice of the type of technology concerning SIOT estimation has been left to the member countries by the UN Manual. Choosing technology assumption in Iran has been based on expert judgments, institutional data requirement and avoiding negative elements. The question which arises here is that, would it be possible to choose the appropriate type of technology for estimation of SIOT in Iran? The main aim of this paper is to suggest an econometric test of hypothesis method concerning the choosing of technology type. For this reason, we suggest a Fisher type (F) test in which the Product Technology or the Activity technology will be chosen. If the Product Technology is dominant, the SIOT will be estimated based on the Product Technology. Otherwise, the Activity Technology may be applied. The results of the tests concerning 2011 SIOT have shown that Product Technology Hypotheses is more appropriate for some sectors, whereas Activity Technology Hypotheses for other sectors are not valid.
