In recent decades, unnecessary growth in health expenditures of developing countries, and the importance of physicians' behavior in health market, have made investigating determinants of health expenditure on the one hand and the theory of physician induced demand (PID) on the other, as two of the most important issues in health economics. Therefore, using data collected through filling out information collection forms by psychiatrists and patients of East Azarbayjan in 2016 and employing hierarchical linear modeling methods (HLM), this study, examines the determinants of the average expenditure of each visit to a doctor and investigates the theory of PID within psychiatrists in the East Azarbayjan province. The results show that in psychiatry, although psychiatrists are “doctors tend to profit”, there is no physician induced demand. Results also indicate that patiant’s income, patiant’s education level, and condition of illness have significant effects on the average expenditure of each visit to a doctor. According to these results, it is suggested that in order to reduce unnecessary health expenditure, patient information on medical care should be increased, and government monitoring and control over the national health system must be increased.

Reducing or eliminating subsidies for the electricity sector in the economy is a good way to control the daily consumption of electricity and balance the cost of supply and demand players. By increasing or decreasing electricity subsidies, indirect taxes are reduced or increased. Under these conditions, assuming the stability of primary inputs and the stability of power generation technology and based on input-output modeling, the effects of rising electricity prices on the prices of manufactured goods in the 75 economic sectors were measured. The results of this simulation, which was performed under three models of electricity price increase of 7%, 16%, and 23%, show that the "communications", "manufacturing of food products" and "manufacturing of non-classified non-metallic mineral products" sectors are the highest. Taking into account the total benefits of increasing the price and its socio-economic costs for residential subscribers, the scenario of "increasing the tariff price of residential subscribers by 7%", "increasing the tariff price of public consumption by 16%", "increasing the tariff price of Water and Agriculture Production subscribers by 16%", "Increasing the tariff price of Industrial and Mining Production Subscribers by 23%" and finally "Increasing the tariff price of Other Uses Subscribers by 23%" can be a proposed tariff in increasing the price of electricity.

Crime is a phenomenon that exists in all societies and affects the useful functioning of different parts of a country. Also, Iranian society is not safe from the harms of this phenomenon. Given the destructive effects of crime in society, recognizing the factors affecting it makes it possible to fight it more effectively. For this purpose, this study has investigated the effect of misery index on the rate of theft in 30 provinces of the country during the years 2008-2018. In order to achieve this goal, the Panel generalized method of moment (GMM) has been used. The findings of this study have shown that the misery index has an increasing effect on the crime of theft. In other words, the misery index through the two channels of inflation and unemployment has destructive effects on people's living standards and puts them on the path of committing crimes such as theft.
