Economic sanctions are a low-cost tool that replaces military action with a high economic, political and human cost. The severity of the effects of sanctions depends on the degree of dependence of the target economy on the outside world, the cooperation of the international community with the ones imposing sanctions, and the potential ability to substitute domestic production with imports. If domestic supply is sufficiently resilient, sanctions act, such as an import substitution policy, can lead to higher growth and more employment. Otherwise, sanctions will act as a lack of domestic supply. This study evaluates the welfare effects of sanctions on basic items - whose rising prices affect living standards. We use a multiple choice model and logit function, the income and cost effects of sanctions as well as the impact of exchange rate changes on the price of basic goods on the welfare standard and the probability of households joining the poor group are considered. The results show that, due to the inelastic domestic supply, the possibility of substituting imports is limited, so the cost effects are dominant for the year 2019, in the effective exchange rate scenario, poverty growth is estimated at %2.2 (about 1828 thousand people, and in the official exchange rate scenario, poverty growth is 3.1 percent (and about 2575 thousand People have joined the poor group).

This study utilizes the continuous wavelet transform approach and time-frequency domain analysis to shed new light on the causal relationship between land, housing prices, liquidity , and economic growth. According to the results of the research: 1) In the short term (12-month cycle), the relationship between housing/land prices and liquidity is two-way and direct, while in lower frequencies (long-term), a direct causal relationship from liquidity to the growth of housing/land prices is evident. 2) Analysing the dynamics of the causal relationship between housing/land prices and economic growthindicates a long-term causal relationship between these variables. 3) In the medium and long term, a stable, strong, and in-phase relationship exists between the ratio of liquidity to GDP and the ratio of the housing price index to the price index. This implies that when the liquidity-to-GDP ratio increases, leading to a higher influx of liquidity into the land and housing sector, the housing price index surpasses the overall price index.

This study aims to introduce the microstructure approach to the exchange rate as the 4th generation of exchange rate models and to apply it in a simulation model to study the effects of transparency of macroeconomic data on exchange rate fluctuations. The microstructure approach to the exchange rate is developed to include decentralized and multi-layer structure of currency markets along with information complexities in this market and the role of trading mechanisms in exchange rate determination. After introducing this approach, we have developed our theoretical model to use it for simulation. In this simulation, we have studied the effects of transparency of macro data release on exchange rate fluctuation. To achieve this goal, we have used two variables of “delay in macro data release” and “error in macro data release”. Our simulation results show that an increase in macro data release delay leads to higher volatility of The exchange rate. This is because of increasing uncertainty for economic agents. In addition, an increase in macro data release delay leads to a farther delay in responsiveness of the exchange rate to movements in its macro fundamental variables. Although we have found a non-linear relationship between the “error in macro data release” variable and exchange rate volatility, the magnitude of this effect is less than the effect of the “delay in macro data release” variable on exchange rate volatility. Based on our results, we recommend that to have lower exchange rate volatility, authorities should increase the transparency of macroeconomic data releases and especially they should lower the delay in macro data releases.

The significance of oil market and its impact on economic growth in oil-exporting and oil-consuming countries has led to examination of factors affecting it in different studies. Financial market and its components have penetrated in traditional oil market and this has resulted in creation of exchanges to trade oil-related securities. Therefore, the importance of financial markets has emerged not as an exogenous variable but as an endogenous variable within the oil market. Scientific results of the research demonstrate that the long-term impact of futures markets on the oil market is definite, however during the crises, due to the concerns about complicated crisis conditions, the effective time horizon becomes short-term, and consequently it is the spot market that influences future variables. Therefore, it is suggested that, in order to prevent the impact of global financial crises on the state’s budget, we have to monitor the financial markets and also participate in oil futures market which has the advantage of generating risk coverage and ensuring the country’s budget to become secure against price fluctuations of international markets. Finally, by undertaking a wise strategy of speculation, we can take advantage of potential opportunities, if supported by domestic financial institutions and Ministry of Petroleum and, therefore, earn the country tremendous revenues.

First studies in inflation forecasting were mostly based on traditional Philips curve in which the relation between inflation and unemployment is studied. However, after several decades and especially after the Lucas criticism, Philips curve faced great takeovers. The new Philips curve ties real and expected inflation, not to unemployment rate but to a scale of the marginal cost. Since in the original form of Philips curve, marginal cost stimulates inflation, it is difficult to formulate models that are effective in predicting inflation. Therefore, using TVP-DMA model, which has the ability to fix these deficiencies, we try to improve predictability of inflation in Iranian economy. An independent variable in conventional models can be either significant or insignificant while in TVP-DMA model, it may be significant during a period of time and insignificant in rest of the times. Therefore, this approach lets us to determine the periods in which an independent variable is significant and when it is not. In this study, we use seasonal data during the period 1991-2015. The results based on outputs of the TVP, DMS, and DMA models show that, out of 100 time periods under study, the liquidity growth rate in 19, economic growth rate in 7, unemployment in 8, exchange rate growth in 31, changes in the bank deposit rate in 14, oil revenues growth rate in 15, inflation uncertainty in 14 and the budget deficit growth rate in 4 periods have significant effect on inflation. Based on these results, it can be stated that exchange rate growth, liquidity growth and oil revenues growth rate are the most important indicators influencing inflation rate in Iran.

The Followingfollowing paper explores cooperation among Caspian Sea countries for naturalgas exporting to Europe. What is puzzling here is whether environmental requirements, inNabucoo and Trans Caspian Sea gas projects, play an important role in the strategic decisionprocess among three gas-exporting countries in the region: Iran, Azerbayejan andTurkmenistan. using Maskin’s cooperation model, considering externality, , coalitionamong natural gas exporters and importers for the Projects has been exploredIn this paper we answer the question whether a coalition should be formed between the threecountries to export gas to Europe. We also calculate the bargaining power of these twocountries (or three countries?!).The results show that (or all?!) countries have profits to make the coalition for gas exportingamong the Nabucoo project. Given the environmental requirements, Trans Caspian is lessEconomical than Nabucco so Iran can play important and active role to form a coalition toexport gas to Europe in the Nabucco project.

This article explains the differences in size and growth of governments over time. We first divide the theories of government size into three theories relating to demand side, supply side and other theories. Then these theories are empirically tested by a conceptual model for 103 countries and selected groups of countries (Muslim and socialist countries, democracies, authoritarian countries and federal countries) during the period of 1990 to 2010. The results show that among the demand side variables, per capita income, inequality and urbanization, respectively with negative, positive and positive signs, have a significant effect on the size of government. In the case of supply side variabels, indirect taxes have a significant positive effect on the size of government. Concerning other factors (factors other than the supply and demand side variables), the three variables that are the ratio of aging population, the degree of openness of the economy and the rate of female participation in the labor market have a significant positive effect on government size. The results also show that political structure, ideological structure, and presence or absence of centralization not only affect the government size but also the effect of economic variables is different when these structural factors change.

This study reviews a century of structural transformation in distribution views from functional income distribution (between suppliers of inputs) to personal income distribution (between individuals and households). In this transformation some factors have facilitated the process and some factor have preventive role. Welfare governments needs, defects of functional distribution theory, improvement of hardware and software instruments in income and expenditure analysis, growth and inequality theory of Kuznets, individual choice theory of Friedman, human capital theory of Becker and justly distribution of Rawls are positive factors in this evolution and position of functional income distribution in neoclassical notion and Cambridge school and some ambiguity in how a fair distribution play a negative role in this circulation. Transformation of distributional theories in the ground of macroeconomic and microeconomic theories, is a important section of economic science improvement in the past century.
