Municipalities are kind of organizations that due to their diversity in functions and obligations play important roles in urban management .Financing the administration of obligations (urban public finance) is one of the principal tools in achieving targets and urban-related plans. With a glance at the structure of current revenue sources of this administration, it can be found that there is a considerable dependence on the revenue from building permits. This has inappropriate consequences for the economy of cities. Hence, providing an appropriate model that in addition to the quality of being operational and administrative has also the suitable properties can help both the local managements and city economies. To finance municipalities, specific criteria have been offered. In this study, in addition to classifying and grading the presented criteria, the current sources (revenue items) have also been graded, using multi-criteria decision making. And also the pattern of minimum expenditures supply has been modeled. The analysis of urban public finance in Isfahan and generally in Tehran shows that despite having the proper potentials in acquiring some revenues the urban management system relies heavily on building permit. In metropolitan areas, up to 50% of expenditure is obtained from building permit. This is not an appropriate financial strategy. Finally, we suggest that municipality should finance all of its expenditures through tax on pollution and fuel, consumption tax and property tax.

The unequal allocation of economic resources, or other resources of wealth, regarding to the efficiency among the factors of production, is considered as one of the most important condition of optimal resource allocation in the market system. In other words, the market mechanism in the process of allocating resources among the factors of production rewards to the resources with higher returns. So, the article’s main question is whether the unequal distribution of votes similar to the unequal distribution of money, can be applied in the process of the optimal allocation of citizens' benefits in the democracy system? The answer of this question has been given by the monetary model which is similar to the democracy, using the concept of Anthony Downs’s (1957) rational voter hypothesis, the idea of Paul Samuelson's (1958) monetary economic model, the microeconomic theory of consumption and just one of the major components of the market –the unequal distribution of money–. Using the designed model, we can survey several statuses, Such as: vote exchange possibility (similar to the barter economy) and weighting of votes. The article’s results show that the social contract possibility for exchange and the ability to save money causes to change of the shape and nature of the money from public goods to private goods and the interest rate creation. In this situation, one of the important findings of Samuelson model of monetary is appeared in the space of voting theory. One of the contributions of the monetary model of Samuelson is that one of the origins of the monetary interest rate is population growth. The other results show that the weighting of buyers in the monetary model design under conditions can be led to more efficient choices and social welfare increase ultimately. KEYWORDS: Democracy, Market, Political Market, Money, the Weighting of Votes, Downs’s Rational Voter Hypothesis, Samuelson's Monetary Economic Model.

Social and economic impact of change in the subsidies payment policy have been concern in past recent years. In this paper, a Computable General Equilibrium model is used to analyze the impact of change in subsidies payment system from indirect to direct state, on the price and quantity variables of domestic production and employment level economic sectors in two scenarios. The basic data are used in the framework of SAM year 2001. CGE model establishes the relations between accounts of SAM into a set of simultaneous nonlinear equations, by using the modern general equilibrium theory. In first scenario, indirect subsidy of manufacturing and services sectors is remove and its full payment in cash to the urban and rural households. In second scenarios, indirect subsidy of manufacturing and services sectors is remove and its direct payment to the proportions of 50. 30 and 20 percent to the households, economic sectors and Government respectively. The results show that by change in subsidy payment, composition of production and employment in economic sectors are change. The greatest decrease in domestic production and employment level and also the highest increase in the prices level is observed in the transport products. The mining sector is only sector that is face with positive production growth rate in both scenarios, and for most sector, a decline is forecast. But GDP level is face with decline to equal 2.78 percent respectively in first scenario and 3.05 percent in second scenario. In the end, with comparing two scenarios show that more the direct subsidies paid to households increase, more the domestic production of  some sector growth.

Market economies rely on the payment system to facilitate trade and exchange between businesses and consumers in the product market. "Payment" is the transfer of monetary value. The ability to control monetary policy instruments is one of the challenges of monetary policy in Iran. The reduction of the central bank's control over the money supply and the implementation of monetary policy is due to the change that occurs in the monetary base and the monetary multiplier. The structure of stochastic dynamic general equilibrium models, like other general equilibrium models, aims to describe the behavior of the entire economy and use decision interaction analysis. Wisdom is built on different levels.Due to the existence of sanctions and the lack of clear and correct information on the amount of sales of crude oil and other export items and petroleum products and unnecessary complications in doing the economics paper, it is considered closed, but if the correct information in can be considered as the expansion of the economy.The findings of this section indicate that the central bank's reaction to the growth rate of the total index of the real sector of the economy against the reaction to the deviation of the total index from its long-term equilibrium level can be more effective in reducing the real effects of the shocks of the real sector of the economy on macroeconomic variables. . Because the central bank controls the status of asset returns in other parallel markets such as currency, price levels, deposits and loans, and therefore the reaction to the emotional dynamics of the market return against the reaction to the market index level further guarantees macroeconomic stability.

Today, the importance of the effectiveness of economic growth on inflation is not hidden from anyone. The literature expresses different views about the effect of inflation on economic growth. Some studies have emphasized the existence of a positive relationship, some studies have emphasized the existence of a negative relationship, and some have considered the effect of inflation on economic growth to be neutral. In recent decades, Iranian economy has faced inflationary conditions that can affect economic growth. Macroeconomics uncertainties can also intensify the negative effect of inflation on economic growth. Considering the importance of the issue, in this article, the vulnerability of economic growth to inflation in the conditions of macroeconomic uncertainties is investigated. For this purpose, using time series data during 1370-1401, the dynamics of the effect of inflation on economic growth has been investigated, using the autoregression method with a distribution with an interval. Since inflation at different levels and thresholds can have a different effect on economic growth, the threshold effect of inflation has been investigated using the threshold regression method. Considering the different effect of inflation in macroeconomic uncertainty, the effect of inflation at the level and threshold on economic growth has been investigated once considering macroeconomic uncertainty and another time without considering macroeconomic uncertainty. E-GARCH method has been used to extract macroeconomic uncertainty. In the models examined in the article, uncertainty of exchange rate, uncertainty of liquidity and uncertainty of stock price index were considered. The findings indicate, inflation at the level without macroeconomic uncertainty has a positive effect on economic growth, but taking macroeconomic uncertainty into account, inflation at the level has a negative effect on economic growth. Also, considering macroeconomic uncertainty indicates that the negative effect of inflation on economic growth is intensified.

Extended Abstract
Introduction
Subjective well-being has become an increasingly important concept in welfare economics, happiness economics, and social policy analysis. Unlike objective welfare indicators such as income, employment, consumption, or access to public services, subjective well-being reflects how individuals evaluate and experience their own lives. In societies undergoing economic, institutional, and generational transitions, individuals’ assessment of their living conditions relative to their parents can provide a meaningful indicator of perceived progress or decline. Iraq represents an important context for such an analysis because the country has experienced economic uncertainty, institutional challenges, demographic pressures, and rapid digital transformation. In this setting, internet use may influence individuals’ perceived well-being by expanding access to information, learning opportunities, social networks, public services, and economic prospects. However, the relationship between internet use and subjective well-being is unlikely to be direct, linear, or uniform across all individuals.

Background and Innovation
The literature suggests that the welfare effects of internet use depend not only on access but also on the intensity, quality, and purpose of use. Internet use may improve well-being by reducing information costs, facilitating communication, supporting learning, and creating new opportunities. At the same time, it may generate adverse effects through social comparison, misinformation, excessive use, or passive consumption of digital content. Therefore, recent studies emphasize the importance of human capital and digital capability in shaping the welfare consequences of internet use. The main contribution of this study is threefold. First, it focuses on intergenerational relative subjective well-being, rather than conventional life satisfaction. Second, it distinguishes active internet use from mere access or satisfaction with access. Third, it examines whether education moderates the association between internet use and relative subjective well-being.

Aim and Method
The main objective of this study is to examine the relationship between active internet use and intergenerational relative subjective well-being in Iraq, with particular emphasis on the moderating role of education. The dependent variable is an ordinal measure of respondents’ evaluation of their current living conditions compared with their parents’ generation. It takes three ordered categories: worse than parents, the same as parents, and better than parents. The empirical analysis uses micro-level data from the eighth wave of the Arab Barometer survey for Iraq. Given the ordinal nature of the dependent variable and the survey design of the data, the baseline specification is estimated using a survey-weighted ordered logit model. The model controls for age, age squared, gender, household size, urban residence, employment status, household income adequacy, evaluation of current economic conditions, expectations about future economic conditions, trust in government, and governorate fixed effects. To assess the robustness of the results, alternative specifications including ordered probit, different measures of internet use, marginal effects, and post-estimation diagnostics are also employed.

Findings
The results indicate that the direct association between internet use and intergenerational relative subjective well-being is not uniform across the population. In the baseline models, internet use alone does not show a strong and stable direct relationship with higher relative subjective well-being after controlling for individual, economic, institutional, and regional characteristics. However, the interaction between active internet use and higher education provides evidence of heterogeneous effects. Among individuals with higher education, active internet use is associated with a higher probability of reporting a “better than parents” status and a lower probability of reporting a “worse than parents” status. This finding suggests that education may enhance individuals’ ability to transform digital access and internet use into meaningful opportunities.
The results also show that household income adequacy, household size, evaluation of current economic conditions, expectations about future economic conditions, trust in government, age, and age squared are important correlates of intergenerational relative subjective well-being. Governorate fixed effects are jointly significant, indicating that regional differences within Iraq play an important role in explaining variations in perceived intergenerational well-being. The robustness checks further suggest that the relationship between digital engagement and subjective well-being should not be interpreted as a simple universal effect. Rather, the welfare implications of internet use depend on individuals’ human capital and their capacity to use digital resources effectively.
Overall, the findings imply that digital policy should move beyond expanding physical internet access alone. Policies aimed at improving subjective well-being through digital transformation should also promote digital literacy, purposeful internet use, skill formation, and the integration of educational and digital development strategies. In particular, strengthening human capital may allow individuals to benefit more effectively from online information, learning resources, communication networks, and economic opportunities.
