  The purpose of this article is to investigate the effect of moral intelligence on free riding. To this end, a two-stage team game with three individuals was designed by providing an experimental environment and a sample of 186 people from the target community (students from Yazd and Ayatollah Haeri Meybod). The results showed that moral intelligence has a significant effect on free riding. In fact, increasing moral intelligence reduces free riding. Based on the results, it is suggested that the level of moral intelligence should be considered in attracting workforce in public and private jobs; in addition, it is intended to promote the moral intelligence of employee in order to increase participation in the work and, consequently, productivity.

  The target of this article is to investigate the effect of inflation on the solvency of insurance companies in Iran. In this regard, panel data regression models was used to specify the model study from 1391 to 1394. The results show that inflation, current ratio and equity ratio have positive and significant effect on solvency, while loss coefficient and reserves ratio have negative effect on solvency. According to the results, it is suggested that insurance companies change their activities from leveraged companies to capital based ones; consider reserves in another part of balance sheet except for the liabilities part; describe a range as the optimal range of current ratio and define some groups of premium related to the average damages.

  This article seeks to find the relationship between happiness and environmental quality. So, the effect of environmental performance index on happiness was evaluated by using data sets of 155 countries during time interval 2006-2016 (as biannual) with panel data method. The results indicate that the improvement of environmental performance index has a positive and significant effect of 6 percent on happiness. On the other hand, the results indicate that the effect of control variables including Gini coefficient and negative impact of environment (An average of negative feelings from environment) was negative, while having the freedom of choice is a positive effect on happiness. Apparently, previous studies confirm the validity of obtained results. Manuscript profile

  The purpose of this article is to achieve the compatibility equilibrium of components. For this purpose, the components compatibility was investigated in the production equipment producers.  In this research, a game has been designed in three stages with considering the available alternatives for equipment producers and service providers, in which the firms decide about compatibility before price competition in selling stages and providing services. Then, by means of static games solution with imperfect information, the game equilibrium has been exploited. The modeling results showed that the component incompatibility is the game equilibrium and the firms with monopolization incentives in providing the after sale services, produce own provided outputs under an incompatible situation. Based on results, is suggested the production equipment byers, if possible before purchase, evaluate the rate of breakdown of production equipment, and also, concurrent with purchasing the system, buy the spare parts.

  The aim of this paper was survey of the government's current and development expenditure impact on private consumption and investment in Iran economy. In this study, Factor Augmented Vector Autoregressive method was used on the base of seasonal data frequency in the period 1370-1394.The results showed that the government's current and development expenditure have a complementary effect on private consumer spending; but government expenditure in two current and development sectors has had  a substitutional effect on private investment. According to the results,  it is suggested that in order to boom and economic development in various economic sectors, the government deal with infrastructure expenditure and on the other hand, help by  increasing private investment subject to no budget deficit increase.

  In this study, the aim is to identify the economic and welfare effects of forming the water market in the Varamin region. Changes in the area under aquaculture, gross profit in two situations (water market and lack of water market) during 2011-2016 were calculated and compared using GAMS software and positive mathematical programming model. The results show that the establishment of the water market would have a positive and incremental effect on the gross profit of farmers in the region. Also, Cultivation of crops such as wheat, rice, barley, cucumber and potatoes, tomatoes and garlic has been more profitable and more crops can be planted.

      The main purpose of this article is to evaluation the impact of fleet renovation on productivity of Iran’s road transportation industry. To meet this ends the data of the Iranian road transportation and the capital-embodied technical progress growth model were used during 1353-1393. The results of capital inventory and labor coefficients showed that the return to scale in the Iran’s road transportation was constant. Also, in this sector, new investment and renovation increased moreover the average age of the fleet reduced and it has resulted to the growth rate of qualitative capital and productivity increased. Therefore, in Iran's road transportation, the direct relationship between fleet renovation and productivity is confirmed. So, the use of superior technology equipment and the replacement of fleets by new and advanced fleets are recommended. Manuscript profile
