If happiness is a good feature of society and development is considered as a gradual movement towards good society, happiness can be one of the goals of developmental policies. In the field of happiness economics, the focus of studies is on analyzing the impact of various economic factors on happiness. But so far, no study has investigated the effect of economic variables on happiness with the panel threshold regression models. In the present study, the effect of eight variables on happiness using panel data for 100 countries in the period 2005 to 2016 in three scenarios was investigated using panel threshold regression method. The results of the research show that the happiness relationship with per capita income, health, consumption, government expenditures and economic freedom is positive and there is a negative relationship between happiness and income inequality, inflation and unemployment. In each scenario, only a threshold value was detected. Consumption expenditures and economic freedom have a positive effect on happiness, and the size of this effect increases with increasing per capita income (threshold variable). Per capita income has a positive effect on happiness, but with increasing income inequality (threshold variable), the effect of per capita income will decrease. It seems, therefore, that the formulation of appropriate policies to reduce income inequality can lead to more social happiness for the society, which will result in increased productivity and economic growth.

Over the past two decades, significant changes have taken place in the banking market power in Iran economy. In addition, economic theories provide different forecasts on the impact of banking market power on firms’ investment. For this reason, the present study examines the impact of these changes on firms’ investment. For this purpose, using the data of Tehran Stock Exchange companies during the period of 2005 to 2016, the investment model was estimated based on Euler's equations and dynamic generalized method of moments. The results of model estimation with confirming the existence of financial friction in Iran economy showed that firms faced financial constraint on investment. In addition, by rejecting market power hypothesis and by confirming asymmetric information hypothesis, the results showed that the declining in banking market power led to an increase in firms' financial constraints. The results also suggest that the firm size has been affecting the firm financial constraints, and increasing in the banking market power has reduced the financial constraints of small firms more than large firms. The results of model estimation with regard to the effect of business cycles indicate that during the boom period, the positive effect of the banking market power on firms' financial constraints has decreased and this effect increases during the recession period.

Quality of government intervention in the economy or in other words the efficiency and effectiveness of government, has a close relation with the development.Because policy makers are often ineffective, inefficient bureaucracy will be created. The inefficiency of the government can be very dangerous for development and economic security and will lead to waste of resources, monopolism, mistrust of government, economic instability and inappropriate institutionalization. This research examines the empirical relationship between the efficiency and effectiveness of government and economic growth in the context of GMM model using combined data for 121 countries of the world in the period from 1996 to 2013 in two separate groups for developing as well as developed coutries. The results show the positive impact of the efficiency and effectiveness of government spending on economic growth.

Due to limitation of energy resources and its importance in the supply chain as the final products for consumers and inputs for manufacturers on the one hand, and On the other hand, due to the large fluctuations in prices and increased greenhouse gas emissions conservation policies and factors affecting supply and demand in recent decades have been considered by the scientific and policy communities. In this study, the relationship between energy consumption, export and economic growth in the industrial sector of the Iranian economy has been tested.For this purpose, the panel data of energy consumption, export and value added of the industrial sector in the ISIC 2-digit level detail over the years 2002 to 2012 were used. To study causality and dynamics between variables in the industrial sector the Toda-Yamamoto causality and vector error correction model were used. The results show bidirectional short-run, long-run and strong causality between variables, Except for one case that from exports to energy consumption and economic growth in the short run, there is no causality.

One of the major concerns for the future of human is living conditions on Earth. Environmental degradation by humans has caused to climate change in addition to vast reduction of natural resources. Recognition of environmental problems and factors is the first step in maintaining desirable biological conditions. Accordingly, in present study, was investigated the effect of shadow economy on environmental pressures and also the role of political and administrative corruption level in this regard. For this purpose, the pressure on nature was measured by sum of energy, mineral, net forest depletions and carbon dioxide damage. Also, panel data of 15 MENA countries from 1999 to 2013 were used to test this relationship. The result showed that relationship between the shadow economy and the environmental pressure is positive and significant. As, a 1% increase in the size of shadow economy increases the pressure on nature to 3.19%. Also, the result showed that the relationship between the size of shadow economy and the pressure on nature are dependent on the levels of countries corruption, so that increase in the corruption level increases the effect of shadow economy on environmental pressures. Therefore, production in the shadow economy of countries causes failure to comply environmental regulations by firms and increase of environmental pressures.

This study uses data from the eight largest Islamic countries known as D-8 for the period 2000 to 2013 concerns to assess the effect of tourism, energy consumption and political instability on economic growth. To address the objective of this study, we utilize both the static panel data approach as well as the dynamic generalized method of moments (GMM) estimator to examine the impact of candidate variables. Our results show that energy consumption and tourism significantly contribute to the economic growth of countries in the D-8 region. Hence, our study lends some support to the existence of the tourism-led growth and energy-led growth hypotheses in the region. In line with our expectation, our estimation results also reveal that political instability impedes the process of economic growth and development in the D-8 countries. There fore, it should be take serious action in these countries to overcome political instability and attract international tourists to boost economic growth. Since energy consumption has the greatest impact on economic growth in member countries, policies that reduce energy consumption without planning to support the growth of the manufacturing sector in these countries, will have disturbing impact on economic growth.

This paper investigates the effect of concentration and advertising on profitability in Iranian Industrial firms, with more than 9 employees. Dynamic panel data technique is used along with the data during the period 1374-1381 to study this issue. The results show that the concentrated industries have a higher profitability than the others. In addition, advertising has a positive effect on the profit of the Iranian industries.
