        In this article, the goal is to design and present a model to determine the effect of macroeconomic and banking variables on the occurrence of asset freezing in the country's banking system using meta-heuristic models. The current research is applied in terms of purpose, in terms of research method, correlation analysis type and in terms of overall research design, post-event and retrospective. In order to answer the research questions, the annual data of macroeconomic and banking variables, during the period of 1399-1390, were collected and using the test of regression models in EViews, Smart PLS software and also the neural network model. It was estimated in SPSS Modeler software. The estimation results of the regression model of the first hypothesis in EViews software showed that the economic variables of GDP, unemployment rate and interest rate, consumer price index, currency strength at the error level of one percent and the economic growth rate variable at the error level of ten percent have a significant relationship. They have a dependent variable (asset freezing). Also, the estimation results of the structural model of the first hypothesis in the PLS software are significantly aligned with the output of the Eviuse software. So; The first research hypothesis is confirmed. Also, the results of the regression model estimation of the second hypothesis in EViews software showed that the intra-bank variable of the bank size ratio, return on equity, and the amount of liquidity at the error level of ten percent, and the variables of capital adequacy, return on assets, bank capital, at the error level of one percent. The percentage has a significant relationship with the dependent variable (asset freezing). Also, the estimation results of the structural model of the second hypothesis in the PLS software are significantly aligned with the output of the Eviuse software. So; The second research hypothesis is also confirmed. Manuscript profile

        The economy of every country is composed of different sectors in which, the relationship amongst them determines the dimensions of the economy of that country. The capital market together with money market make up the financial market as the main arteries of an economy. Their operation has a significant influence on the growth and development of the economy. In cases where there is no constructive relationship between the financial market and economic sectors, economic performance might be subject to distortions. The stock market as a fundamental pillar of the financial market plays a crucial role in facilitating investments in the capital market. Given the importance of expectations in different economic fields, the main purpose of this study, as its title explains, is to anticipate of Iran Mercantile Exchange (IME) gold coin price Therefore, after a brief review of dominant economic theories, a new method, artificial neural network GMDH, is used to forecast the impact of macroeconomic variables( including the rate u.s. dollar as foreign exchange, the price of gold coin, the price of gold and oil in termes of dollar, the over-all index of stocks, the delivery date of gold coin) on the gold coin price. The GMDH Algorithm is a nonlinear model to anticipate complex systematic relationships between variables of the model. The special feature of this deductive algorithm is recognition and screening of the most effective variables to estimate the model with training samples and omit the non-significant ones from the simulation process with testing samples. So, an attempt is made to solve the model via iterative methods to minimize the typical standard Error like RMSE, MAPE, and so on. Manuscript profile
