Income inequality is one of the important and key issues in the economy, which, considering its function and consequences, can affect people's health in various ways and endanger the stability and stability of the socio-economic system. Today, most countries suffer from inequality in the distribution of wealth and income due to various reasons. For this reason, this study examines the effect of the good governance index in reducing the effect of Covid-19 on income inequality using available data for countries that export more than 50,000 barrels of oil per day during the years 2000 to 2021 using a panel econometric model. The data has been paid. The results of the research show that the death rate from covid-19 has had a positive and significant effect on increasing income inequality in oil-rich countries. On the other hand, the variable of good governance *Covid-19 with a negative and significant effect on the variable of the Gini coefficient has reduced income inequality.

The equity premium is obtained from the difference between the return on the risky stock asset and the return on the risk-free asset; the failure of financial theory to explain high equity premium is known as the equity premium puzzle. This puzzle was introduced for the first time by Mehra and Prescott in the framework of the C-CAPM model and states that stock returns are so high that it cannot be explained by the fluctuation of real consumption growth. Therefore, the examination of the puzzle is important because it provides the basis for the correction of models that lead to failure when faced with financial data. The purpose of the present study is to investigate the equity premium puzzle in Iran. Focusing on the relationship between the real and financial sectors, this study has specified a DSGE model in accordance with the conditions of Iran's economy. The specified model can investigate the equity premium puzzle in Iran by applying technology shocks, government spending, oil revenue, stock price index shock and money supply and the effect of these shocks on asset returns and consumption. The results show that the productivity shock, oil income shock and stock price shock in the high risk aversion parameter while smoothing the consumption and creating high equity premium can explain the equity premium puzzle in Iran.

Russia’s Position in the world gas Market and common membership of Russia with Iran has given importance to Analysis of Russia's asymmetric behavior productive in the world gas market. Russia’s Position in the global gas Market and it’s excessive capacity in gas production provides an opportunity which it’s Increase (decrease) in longtime producing natural gas with changing in variables such as other members of gas exporting countries production, shale gas production, world natural gas demand, world natural gas price and the crude oil world price doesn’t change in order to stabilize symmetric and aligned market. In this paper, Russia gas productive behavior was investigated by using seasonal data from 2001 to 2021 and by nonlinear autoregressive distributed lags (NARDL) method. The results showed that during changes (Increase & decrease) in mentioned variables; as the most important variables affecting the formation of changes in the supply and demand of the world Gas, Russia Gas productive behavior in the direction of aligned market stability will not change. And in the GECF, Russia shows a similar behavior to Saudi Arabia in the OPEC.

In this article, the foreign exchange market index (EMP) in the countries that export metals, spices, raw materials and energy during the period of 1990-2020 by applying the simple panel transition regression model (PSTR), two regimes on the real price of food, food, energy and raw materials , show that the currency market pressure has a negative and significant effect on the real price of food, metals, energy and raw materials among the countries that export the studied goods, so that the level of trade balance shows a negative and significant effect in a linear and non-linear manner on the pressure of the foreign exchange market, on the other hand, the real price index of goods in both regimes has strengthened the pressure of the foreign exchange market in the exporting countries, in the food exporting countries The commodity price index shows a positive and significant effect on the foreign exchange market pressure in two regimes, and the net foreign asset also has a positive and significant effect in both linear and non-linear regimes, and the Balassa-Samuelson effect in the two regimes of exporting countries. Food has a positive and significant effect on the pressure of the currency market. In countries that export raw materials, price indices and trade balance levels have a negative and significant effect on currency market pressure in the first and second regimes, on the other hand, net foreign assets have a positive effect in the first regime and a positive effect in the second regime.

An extensive and growing literature has documented the existence of social preferences, their economic and political consequences, and the various conditions under which they affect the equilibrium and outcomes of human interactions. In this research, by using the Global Preferences Survey (GPS) data, an attempt was made to investigate the effect of age and gender on social preferences for the entire country and provinces. The results of multivariate regression showed that, firstly, people's age has a positive and significant effect on trusting others and altruism, and it has a negative and significant effect on negative reciprocity, but it does not have a significant effect on positive reciprocity. Secondly, gender only has a negative and significant effect on trust. It means that women have less trust. Thirdly, income and education have a negative and significant effect on trust and have a significant and positive effect on altruism and positive reciprocity and do not have a significant effect on negative reciprocity. Also, the ranking of the country's provinces was calculated and presented based on the constituent elements of social preferences (trust, altruism, positive and negative reciprocity). Based on the findings of the research, it was found that Iran is higher than the world average in terms of altruism, trust and reciprocity, and Markazi, Lorestan and Ilam provinces have the highest rank in trust, altruism and reciprocity, respectively.

The aim of the current research is to present a model for the risk analysis of 30 large companies in the Tehran Stock Exchange using the multivariate factor stochastic volatility model (MFSVM) in the framework of the non-linear state-space approach. In this framework, the volatility of stock returns is divided into two components, "volatility arising from latent factors" and "idiosyncratic risks", and the dynamic correlation matrix of the volatility of stock returns is estimated. In this regard, the weekly data of companies' stock returns during the period of Jan. 10, 2018 to Oct. 7, 2023 have been used. The results of the research indicate that, first- three hidden factors affect the volatility of stock returns. The first factor has affected stocks related to companies active in the oil products industry, chemical products, basic metals, mining, and investment funds. The second factor has had the largest impact on banks. The third factor has also had an effect on bank stocks to some extent. Second- the strongest posterior pairwise correlation exists between “GDIR” and “PTAP”, “PASN”, and “FOLD”, with correlation coefficients of 74%, 73%, and 71%, respectively. Additionally, “FOLD” exhibits a 69% correlation with both “PASN” and “PTAP”, as well as correlations of 66% each with “MSMI” and “MADN”. The weakest correlation coefficient is between “GDIR” and “BPAS” (-10%). Third BPAS (Pasargad Bank) experiences the lowest correlation with the stock network, while GDIR (Ghadir Investment Company) exhibits the highest correlation.

The basic questions of economic growth models, including the relationship between types of capital and the rate of real growth, have always been a concern of scientific and political circles. In many empirical studies, it has been shown that physical capital and social capital each affect the amount and quality of economic growth, but less has been discussed about the interactive effects of investment types on economic growth. In this study, the effect of social capital on the interaction between physical capital and Iran's economic growth has been investigated using the mild regression model (STR). The studied period for Iran is 1346 to 1400. Four indicators corresponding to Fukuyama's indicators have been used to measure social capital. The results of the study of the variables and the model used showed that, at different levels of social capital, physical capital has a different effect on Iran's gross domestic product, and the fluctuations of social capital during these years have had an effect on the effect of physical capital on Iran's gross domestic product. The way that in the period when the fluctuation of social capital is more, the fluctuation of the effect coefficient of physical capital on production increases.

The present study aims to investigate the role of organizing informal street businesses in the development of food tourism. The statistical population of the research included tourists and street food visitors from the tourist destination of Tehran, and the number of samples was calculated based on the sample size calculation formula for an unlimited statistical population of 384 people, who were selected based on the available non-random sampling method. The data collection tool in this study is a researcher-made questionnaire whose validity and reliability were confirmed. The data collection tool in this study is a researcher-made questionnaire whose validity and reliability were confirmed. Data analysis was done using path analysis and PLS software, and the effect of personal and collective organization of informal jobs on tourists' satisfaction with food services was investigated. The results showed that there is a significant relationship between personal organization of informal jobs and satisfaction with food services (factor loading = 0.582, t-statistic = 7.0532). Also, there is a positive and significant relationship between the personal organization of informal jobs and satisfaction with food services (factor loading = 0.486, t statistic = 9.1246) and between the collective organization of informal jobs and satisfaction with food services (factor loading = 0.181, t statistic = 2.6051 ) was also observed. These findings can help tourism planners and managers to improve the quality of services according to the needs and expectations of tourists and, as a result, improve the overall experience of tourists in Tehran and 30 Tir Street.

In recent years, with increased access to relevant data and statistics, especially inter-country input-output tables and micro-level data within companies, as well as advancements in computer data processing capabilities for managing these vast datasets and information and communication infrastructure, the possibility of efficient joint use of databases for analyzing foreign trade has been provided. The aim of this paper is to implement the decomposition method of Borin and Mancini (2023) on Iran's gross exports using a source-oriented approach and the exporter's perspective as a baseline analysis for decomposing the value added in Iran's gross exports of economic activities. The contribution of this paper to the Iranian economic literature can be summarized in the following three subjects: Firstly, it uses one of the inter-country input-output database (ICIO) for the year 2016, considering Iran, for empirical documentation. Secondly, among the existing theoretical frameworks, it focuses on the latest theoretical framework proposed by Borin and Mancini (2023) with a source-oriented approach and the country's perspective for economic activities in Iran. Thirdly, it provides a structural interpretation of Iran's economy for the year 2016 and can be used by researchers and policymakers regarding the global value chain of Iran's economic activities.

Financing is always one of the most important issues of businesses. The Initial Coin Offering method is a new way of financing businesses based on blockchain technology. This method has been noticed due to its potential in attracting high capital from all over the world in a short period and in absent of third party. Therefore, describing this method and identifying the factors affecting its success/failure is useful. In this article, using the logistic regression method, we have investigated the factors affecting the success of Initial Coin Offering method among 307 completed projects during 2018-2016. Two target variables: "Total funds collected" and "Hard cap achievement percentage" as success criteria have been considered and the effect of project, campaign, social networks and team characteristics in separate models have been investigated. By obtaining the selected models based on their performance and prioritizing the features using the Permutation Importance (PI) technique, this article shows that the "Business model available" according to the results of both selected models, has important impact on the success of an ICO. Also, the most effective features of the first selected model under the three categories of project, campaign and social network are respectively " White paper-pages ", " Token share presale investors" and "account GitHub" and the most important of them in the second selected model under the two categories of project and campaign are, respectively, "Use of proceeds mentioned" and " length_crowdsale".
