Abstract
Construction projects are the basic requirements of sustainable development and growth. Inefficient procedures of implementing the construction projects, regardless of our financial and administrative capacities, has imposed a large amount of unfinished and occasionally stopped projects to national economy. Since there are various components that affect the fate of projects, therefore, the main purpose of this paper is to answer this question that whether the political cycles affect the adoption and implementation of provincial construction projects or not? In order to answer this question, two hypotheses are considered in this paper. Therefore, GMM dynamic method was used to estimate the model and test hypothesis in the years 1997-2014. Hypothesis one: political cycles affect the fate of construction projects, and the second hypothesis: the impact of political cycles on the adoption and implementation of construction projects are larger in the year prior to political cycle (election). Therefore, in order to estimate the model and test the research hypothesis, provincial data during the years was used. Results of testing two hypotheses suggest that parliamentary and presidential political cycles have a significant positive correlation with the construction projects. Results also show that the presidential political cycle has a larger impact on construction projects, meaning that the impact of political cycles on the process of adopting and implementing the construction projects in the year prior to the political cycle is larger. In this regard, in order to eliminate the impacts of the governmental and parliamentary political cycle on construction projects, it is recommended to determine a competent authority that has the necessary qualifications as well as the sufficient degree of independence and supervision power over the project's Feasibility studies. The referenced mentioned will be approve projects based on objective justification-technical and district-based studies and it prevents the adoption of development plans based on the political considerations of the government and parliamentarians.

Abstract
Risk-taking channel refers to the banks’ risky activities following the expansionary monetary policy. This channel may affect the financial and output stability. The risk-taking channel can influence bank soundness and hence be a source of financial instability and financial crisis. This topic has been the focus of many researches after the financial crisis of 2008. Using the structural vector autoregressive model, this paper investigates the existence of a risk-taking channel in Iran’s banking system for the period 2006:2-2015:1. The results of impulse-response functions confirm the presence of risk-taking channel in the Iran’s banking system. This channel is considered to be one of the sources of high non-performing loans in Iran’s banking system. Therefore, banking supervision and macro prudential policies may reduce the banks’ risky activities. Moreover, introducing risk-taking channel into the central bank’s loss function might be helpful in achieving financial stability and reducing the negative impacts of risk-taking channel on output and economic growth in Iran.

Abstract
The purpose of this study is to evaluate environmental productivity changes in Iranian manufacturing industries, with two-digit ISIC codes, during 2003-2014. For this purpose, Meta-frontier Non-radial Malmquist CO_2 emission Performance Index (MNMCPI) is used. This index considers technological heterogeneities of industries. Empirical results indicate that, during 2003-2014, MNMCPI has grown, on average; the highest growth rate belongs to industries with medium technology. Also, all three indices of EC, BPC and TGC, as MNMCPI components, experienced growth, on average. TGC has the greatest impact in industries with medium technology while BPC has the greatest impact in industries with high and low technology. In general, BPC had the greatest effect on MNMCPI growth.The highest growth rate in EC index is observed in industries with low technology and the highest growth rates in BPC index, which shows the effect of innovation, and in TGC index are observed in industries with medium technology. Therefore, based on TGC index, industries with medium technology level are leading technological industries. Rregression analysis shows that energy intensity has a negative and significant effect and R&D has a positive significant effect on MNMCPI.

Abstract
The business cycles are one of the most important economic indicators that they show the changes in economic activities during time. The study of business cycles is important because the understanding fluctuations in GDP and effective factors on these fluctuations help policy makers to plan better and more efficient. The main purpose of this paper is to investigate the effects of oil price shocks on business cycles dynamics in Iranian economy during period of 2005 to 2017 by using non-linear Markov switching model with the time varying transitional probabilities (MS-TVTP). So, first, the oil price shocks were extracted in four different modes, and then the effect of them on recession and boom regimes are investigated. The results of MS-TVTP model show that business cycles are affected by oil price fluctuations and shocks in Iran’s economy. The results indicate that, in all four modes which oil price shocks were calculated, the positive shocks in oil price increase the probability of staying in boom regime. Also positive oil price shocks increase the probability of transition from the recession regime in Iran’s economy. Also, with relative comparison of the coefficients of oil price shocks in the probability of staying in boom regime and transition from recession to boom regime, it can be argued that positive oil price shocks in recession period increases the probability of transition from recession more than the boom regime. In other words, oil price shocks in recession periods have a greater effect on rotation of economic situation and increase the probability of transition from recession regime, but in the boom regime, the positive oil price shock lead to increases the probability of staying in boom regime a little.

Abstract
The labor market, as one of the four markets, plays an important role in economic growth and development. So review developments in the labor market because of its close relationship with developments in other sectors is of great importance. This study tries to examine the dynamics of the labor market by adjusting for a New Keynesian dynamic stochastic general equilibrium model for the Iranian economy. After the model was solved, the obtained equations were linearized and their parameters were estimated using the economic data of Iran (2005-2017) by the Bayesian method. Comparing the model's moments with the economic momentum indicates the success of the model in real-world simulation (production, consumption, investment, unemployment, and participation rate). Impulse Response Functions Survey shows that participation rates are consistent with cyclic behavior. On the other hand, in response to shocks (monetary, oil revenues, government expenditures, and public sector employment), increased employment, but the unemployment rate has changed slightly due to the change in the participation rate and the change in the size of the active population, which represents the sustainability of the unemployment rate.

Abstract
Given the importance of the issue and the undeniable role of the environment in the community's life, in this research, it is attempted to test the hypothesis of the relationship between the government size and composition of government expenditure (Current and developmental) on carbon dioxide emissions in Iran during 1971-2016 based on autoregressive distributed lag approach. To better explain, the above hypothesis is based on two parts of production (production industries) and Consumable (household, commercial, general; and transportation) has been investigated. Long-run results show that despite the fact that government size does not affect carbon dioxide emissions; the current cost ratio and developmental spending ratio of government respectively have a direct (undesirable) and reverse (favorable) effect on carbon dioxide emissions. In addition, the developmental spending ratio of government in both production and consumable sectors has a reverse effect on the carbon dioxide emissions of these sectors. However, the current cost ratio of government in both sectors does not have a significant effect. Energy intensity has a direct effect on carbon dioxide emissions in general format, and although the energy intensity of the production sector has no significant effect on the carbon dioxide emission ratio in this section but in the consumable sector, energy intensity is associated with direct (undesirable) effects on carbon dioxide emissions.

Abstract
Life insurance is one of the most important economic instruments. Considering the important role of life insurance, this study investigates the life insurance capability in Iran. For this purpose, the Panel ARDL model has been used. Then, for the period 1990-2016, suitable models for the first group (Iran with the leading countries in the industry), the second group (Iran with the countries that were close to Iran in premiums) and the group Third (countries in two groups) were estimated. Based on models, the fitted value of life insurance premiums per capita in Iran is analyzed and compared as the potential or optimal level in each groups. The results showed that in each group, the actual life insurance premiums per capita in Iran are significantly lower than the optimal level. The capacity level of life insurance in Iran compared with first group is 46%, and compared with second group is about 42% and compared with third group is about 44%. The results indicate that Life insurance in our country has a high potential, and a large part of the insurance capacity in our country has not yet been fully acquired.

Abstract
Speculative demand in the land and housing market has a fundamental role in raising the price of land and housing and causing a diversion and invasion of the housing sector with the aim of profit. The government, by imposing a tax on rent of land and housing return, seeks to control speculation, allocate the land resources and urban housing and make money to build the urban infrastructure. In this study, optimal taxation on the return of housing capital is analyzed in the framework of a dynamic optimization model in Iran. Then, the calibration and sensitivity analysis of the macro variables was done to change the tax rate on housing capital return. Finally, using the GAMS software, the optimal path of macro variables was simulated in different scenarios during the period (2016-2040). In steady state, the results of the sensitivity analysis of macro variables indicate that by increasing the tax rate on the return of housing capital from zero to 25%, and decreasing the tax rate on the return of business capital from 25% to zero, increased the level of business capital per capita, production per capita and consumption per capita by 50.62%, 13.47% and 25.27% respectively, and decreased the level of housing capital per capita by 31.5%. Also, the results of the simulation indicate that the imposing tax on the return of housing capital at a rate of 4% compared to the current state of the economy, has led to upward the optimal path of business capital per capita, production per capita and business capital per capita and gone down housing capital in the long run during the transition period.

Abstract
The impacts of the tourism industry on economic growth can be divided into two categories: direct and indirect (spillover) effects. In the field of tourism, direct impacts have been the subject of many studies but the analysis of spillover effects, particularly the effects from tourism infrastructure development, have received less attention. This study, with an analytical approach and along with examining the quantitative methods and analysis of the spillover effects of various variables affecting the development of the tourism industry, has investigated these impacts for each the variables and in each province. For this purpose, it has used spatial econometric models. The results confirmed the existence of spatial fixed effects and was applied Spatial Durbin Model (based on Lagrange coefficient test). The results show a positive and significant impact of transport infrastructure variables (road, rail, air) and travel agencies on the growth of value added in the tourism industry. Investigation of the spillover effects of infrastructure variables on growth of value added has shown that, except for Accommodation services, other tourism infrastructure variables have negative spillover effects for neighboring provinces, and also have positive spillover effects for other (non-neighbor) provinces. The negative spillover effects on the tourism growth of the neighbor provinces are due to competition impact and relative stability in the number of domestic tourists, and the positive spillover effects on non-neighbor provinces are due to factors such as the development of multi-purpose trips and increased market access.

Abstract
Due to pension fund problems in Iran, the multi-pillar social insurance system has been released in 2017. According to this, the first pillar is regarding to low income groups and finance through the public fund. The second pillar is defined benefit and finance pay as you go. The third pillar is defined contribution and fully funded finance. Contributions are transferred to the individual account. The pension fund directors supposed to investments the accounts and to return the Contribution fund and its returns in retirement time. The main issue is that the old age pensions are not guaranteed in this plan and face with financial risk and inflation. Due to high inflation of Iran’s economy, the main challenge of third pillar plan is the inflation. This paper is main to inflation hedging in defined contribution pension plan by Investing in Tehran Stock-Exchange. By using NARDL model and 133 monthly data up to 2020 the results show that TSE index can hedge the inflation.

Abstract
Money Laundering (ML) reduces the confidence of investors to the financial market, worsen political instability and deviates resources allocation to unproductive sectors by weakening of financial institutions credit. In the ML, illegal resources are entered into the legal economy secretly and outside formal control whereby it has hidden nature. The aim of this paper is to study the different sizes ML and its changes in Iranian economy in the context of latent variables literature using Partial Least Squares Structural Equation Modeling (PLS-SEM) over the period 1360 to 1396. According to the results from paper firstly, drug trafficking and theft crimes have a positive and significant effect on ML trend. Besides that, economic conditions influence an individual’s motivation to enter illegal activities. Secondly, ML growth is associated with decreasing economic growth and increasing the volume of cash that waste economic stability. Thirdly, ML has an upward trend which based on it can be anticipated that in spite of crimes growth, especially drug trafficking, the increasing trend of ML will continue.

Abstract
Investigating consumer behavior and rationalizing it in selecting different goods and services is important because it measures individuals 'preferences over domestic or foreign goods and demonstrates the impact of impulses and policies as a structural failure or a change in individuals' preferences. In other words, the validity of the assumption of rational consumer behavior is examined. The test of revealed preferences is a powerful way of examining changes in family preferences. Therefore, the purpose of the present study is to investigate the stability and structural failure of urban consumer preferences for bread basket in the period 1996-1999 using strong and weak nonparametric test of revealed preferences in Iran. Initially, the weak preferences matrix revealed using average price data and the amount of bread types derived from household expenditure and income plan in urban areas and comparing consumer choices over different time periods. The results of the WARP matrix analysis show that there are no inconsistencies in the bread basket consumers' preferences. Due to the absence of violations in WARP, further changes in preferences using SARP were investigated. The results showed that rational behavior of bread consumers in urban households of Iran is rejected. Also, the results of K-W statistics indicate that there is a structural change in 2014 and indicate that there is no effect of transient shocks and structural failure in urban consumer preferences for bread. Given the years of failure of the utility function and the rationalization of consumer behavior and rational behavior, it is suggested to consider this in estimating the bread demand function of households.

Abstract
The lack of social security supports and labor market laws in informal employment has strengthened the expectation that poverty in a family in which the head of the household chooses informal employment is greater than in a family in which the head of the household works in the formal sector. Hence, this study attempts to investigate the effect of informal employment with other factors affecting household’s poverty. To this aim, by using the microdata plan of costs and incomes of urban and rural households in 2018, first, the poverty line was calculated based on 66% of the average annual household expenditures by provincial division for urban and rural areas; and poor households were identified as well. Then, according to the presented index in this study, heads of households' employment types were formally and informally determined. In the primary data processing, a comparison between households with employed heads showed that the highest poverty rates were for households whose heads work in informal employment. Next, the estimation of the research model with the dependent variable limited to the basis of pseudo-panel data and random effects in logistic regression was performed in a separate format for 13248 urban households and 13115 rural households in 31 provinces. The results showed that the informal employment of the head of the households has a direct effect on the possibility of household poverty and the rate of influence in urban areas is higher than in rural areas. Furthermore, the head of the household's education, age, and gender have an indirect effect; and the square number of age and size of the household variables have a direct effect on the probability of household poverty. In such a way that the desired effect of education and age, and the undesired effect of the household dimension on the probability of household poverty in urban areas is greater than in rural areas.

Abstract
There is a situation that due to economic shocks and imbalances in structural budgets and its continuation leads to stress in governments in uncertainty conditions. Fiscal stress as a volatile situation in financing of local governments can exacerbate the inability of governments to meet short-term and long-term fiscal commitments and excessive dependence on the central government. So the positive and negative effects of stress are related to the actions and responses of central and local governments. It is essential that policymakers in central and local governments pay attention to accurate and timely signs of fiscal stress for respond to stresses effects. In this study, we tried to clarify the fiscal situation in 31 provinces of Iran by calculating the local fiscal stress index from variables of fiscal structure and budget of each province and then estimate the threshold and spatial effects of the index through Panel Smooth Transition Regression method on economic growth and employment over the period 2005-2017. The results show that border provinces have the highest stress among other provinces, and provinces located in the center or near the capital have less stress. These results indicate the high centralism that exists in the provinces of Iran and has hindered the fiscal independence of local governments so that they can control and regulate their own revenues and expenditures, and in this case, they suffer less fiscal pressure and stress.

Abstract
Price, as an element of marketing, plays an essential role in the decision-making of tourists as well as the income of tourism activists. Therefore, it is essential to identify the components and factors affecting the pricing process. The outbreak of COVID-19 in Iran has drawn the attention of tourism businesses to the necessity of the pricing process and updating the price of tourism products. We examined the pricing components of tourism products by qualitative-quantitative approach and using fuzzy cognitive mapping. We identified 29 pricing factors of tourism products using the opinion of 9 tourism experts. In the next step, 18 factors were selected in 4 dimensions using semi-structured interviews. Finally, we identified the most important components of tourism products’ pricing during the COVID-19 outbreak. The findings indicate that four components of cost coverage and loss prevention, purchasing power, survival in the tourism market, and the extent of tourist demand are more important than other components during the coronavirus outbreak.

Abstract
Collective pension funds have many advantages including larger risk pool and the possibility of interpersonal and intergenerational risk sharing, as well as economies of scale and lower administrative costs. For decades, however, this has been achieved through mandatory participation, while this traditional and mandatory form of contribution is no longer commensurate with the future of work. In this regard, many countries have implemented a combinatorial policy in the form of auto-enrolment pensions and then the granting of opting out authority. However, the sustainability of these schemes will depend on people's motivation to participate or leave. This article tries to examine the motivations of individuals to exit the Iran Social Security Organization (ISSO) pension fund, assuming that the insureds are given the opportunity to opt out once in a certain time. For this purpose, the method of option pricing is used. Findings show that insureds will accept even a 60 percent deficit in fund’s long-term liabilities for the only reason to take advantage of investment income of their predecessors funds or interpersonal and intergenerational risk sharing. It was also observed that an increase in the funding ratio, lower liabilities, a rise in assets and a higher rate of return on investments encourage participation and reduce the incentive to exit. A decline in accrual rate, increase in the contribution rate, higher retirement age, accelerating the adjustment rate of fund deficit due to their detrimental effect on the insureds have a direct negative effect on the incentive to participate and stimulate withdrawal. It should be noted, however, that these factors will also reduce liabilities and increase the funding ratio, thereby contributing to the sustainability of the plan may ultimately reduce the exit incentives.

Abstract
The aim of this study was to analyze the effect of commodity group expenditures on the probability of urban and rural household poverty in Iran. First, using household expenditure-income data in 1399, the poverty line was calculated based on the method of 66% of the average per capita expenditure, which is higher than urban households than rural households. In the following, the research model is limited by a dependent variable and is estimated based on pseudo-panel data in logistic regression by random effects method. The results showed that the expenditures of the communication group have the greatest impact on the probability of household poverty in urban and rural areas and the impact of this group of goods in urban areas is greater than rural areas. In contrast, hotel and restaurant costs in urban areas have a greater positive effect on reducing the likelihood of household poverty than in rural areas. But the cost of durable goods in urban areas, transportation in rural areas, and the cost of recreation and cultural affairs do not have a significant effect on the likelihood of household poverty. There is also no significant difference between the impact of furniture and household appliances, clothing and footwear and health care in urban and rural areas. Between social characteristics of the household, variables of gender and education have a negative effect on the probability of poverty and variables of household dimension and marital status have a direct effect on the probability of poverty of urban households, but these variables have no significant effect on the probability of poverty of rural households.

Abstract
The balance of payments shocks affects different economies and can lead to business cycles. Hence, the main purpose of the paper is to evaluate the effects of different balance of payments shocks, including the shocks of oil exports, non-oil exports, imports, net capital account, real exchange rate, real interest rate and consumer price index, on total output and creation of business cycles. Therefore, in this study it will be tried to evaluate the effect of balance of payments shocks, and their importance, on creation of fluctuations in total production in Iranian economy. For this purpose, the structural vector auto-regressive method has been used during the seasonal period of 2001:02-2021:04. The results based on impulse response functions show that the shocks real exchange rate, real interest rate and consumer price index have negative effect on output and lead to recession cycle in the economy. Also, the shocks of non-oil export, oil export, import and net capital account will be caused to boom cycle in the economy. Meanwhile, the exchange rate shock has had the most effect on output. Finally, the real exchange rate, oil export and real interest rate variables have had the most share in explanation of output variance, while the effect of import has been raised in the next.

Abstract
Applying a favorable tax system has important conditions such as justice and efficiency, therefore, consumption tax and income tax will comply with the principles of benefit and ability to pay. In this regard, value added tax is known as the most important innovation of the 20th century in terms of tax collection on consumption. Since increasing government revenue is one of the important goals of imposing this type of tax, the government has tried to determine the rate of this type of tax effectively and efficiently. Disproportionate increase in value added tax rates can have negative social effects on inflation, economic growth, income distribution, and general well-being in society. It may also have disruptive effects on other variables and sectors of Iran's economy. To manage the rate increase, one approach is to simulate and examine its consequences and effects on macroeconomic variables in the form of a multi-regional calculable general equilibrium model (MRCGE). Three different scenarios were applied and examined to simulate the shock effects of the increase in the value-added tax rate (12% , 15% , and 20 %) on four macro variables of Iran's economy: inflation, gross domestic product, consumption, and investment. The simulations were conducted at the country level using a multi-regional calculable general balance model, known as the ORANI-G Iran model, using the 2016 input-output table and regional accounts of the country. The results indicate that the effect of increasing the tax rate on value-added will increase inflation and investment and decrease GDP and consumption.

Abstract
Recently, time-varying uncertainty has attracted a lot of attention from policymakers and academics and has led to the growth of literature identifying the transmission mechanisms of uncertainty shocks. Precautionary pricing incentive is an important mechanism that amplifies uncertainty shocks. The conclusion from the comparison of allocations under optimal monetary policies is modeled in two common pricing approaches, Calvo and Rotemberg. The main goal of this research is to investigate the optimal monetary policy with uncertainty in Iran's economy under different pricing conditions by modeling two common pricing approaches, Calvo and Rotemberg, which is based on a dynamic stochastic general equilibrium model based on the new Keynesian perspective using The available information and statistics of Iran's economy from 2001 to 2021, have been designed according to the realities of Iran's economy. The results showed that the uncertainty shocks under Calvo and Rotemberg's pricing assumptions when the monetary policy is adjusted based on Taylor's empirical law are spread differently in the Iranian economy. In such a way that they behave like cost pressure shocks under Calvo pricing and negative demand shocks under Rotemberg pricing. However, the optimal monetary policy leads to the stabilization of both inflation and output gap under both pricing assumptions. In other words, adopting optimal monetary policies can lead to economic stability. Because optimal monetary policy removes not only the discretionary savings incentive of households but also the discretionary pricing incentive of firms, the key channel differentiates Calvo's pricing prediction from Rothenberg's pricing prediction under empirical Taylor. According to the results of the present research, it is suggested to use the monetary rule for policy-making to create a nominal anchor for economic actors and not to use discretionary policies in order not to create inflationary expectations in the economy.
