In this paper we have estimated the urban and rural poverty and inequality trends for the important Hormozgan province and for the country as a whole concerning the period 1984-2019.  Doing so, we have used the micro income-expenditure survey data published annually by the Statistical Center of Iran and estimated the non-parametric Gini coefficient, poverty line and then poverty gaps. Then, in order to compare the urban and rural poverty as well as inequality levels regarding Hormozgan with that of the country as a whole, we have used 6 simple regression ANOVA models.  The results indicate that the urban poverty and inequality levels have been significantly lower than that of in the rural areas. Poverty in Hormozgan urban and rural areas have been significantly more than urban and rural areas of the country as a whole, respectively.  However, the Inequality in Hormozgan urban and rural areas have significantly less than those in the country as a whole, respectively.

Since Iran is a regionally dispersed country, this motivates us to analyze whether or not a national fiscal policy has different effects on its provinces’ unemployment and inflation rates using a GVAR approach during 2005:q1-2016:q1 period. The results indicate that one positive standard error as national fiscal shock can significantly reduce unemployment in some provinces. These responses are similar in terms of timing but their amount is different. Also, this positive shock has a negative effect on inflation in some provinces. All responses are approximately similar in terms of timing. In Spite of this similarity, shock responses vary in terms of amount. According to the results in the framework of the models designed in this study, it is proposed that policymakers include the decentralization in the budget planning.

This paper attempts to conceptualize and examine regional endogenous development model for World’s regions and Iran. The work presented here contributes to the design of Manufacturing Industries endogenous development model (MIEDM) which is tested in the World by assessing the domestic forces and drivers of development based in World Selected Countries. The paper introduces a conceptual model for the study and then develops and tests the model with data for the primary Countries of the World. Large and positive correlation is found between measures of latent and explanatory independent and dependent variables in the regional endogenous model. Specifically it is found that such endogenous factors as Institution, human Capital, Entrepreneurship, Leadership, Innovation and Resource Endowment are critical driving force for achieving increased regional productivity and thus tailoring of polices to support regional endogenous development. Based on the results, it is suggested that planners and policy makers consider the capacity and ability of industries to adapt positively to the situation.

This study aims to detect path of currency crisis in different listed industries, in order to manage risk of shareholders in stock market. For this purpose, joint Contagion Test, Joint Coskewness Contagion Test and the Ornstein – Uhlenbeck Process are used. The data used in this study include: stock return of the listed industries and daily exchange rate during 2008 to 2020. The results suggest that currency crises of 2011 and 2018 have transmitted to all export- oriented import- oriented and neutral industries (except mass construction). Moreover, the findings support the fact that starting point of crisis contagion in both currency crises is pharmaceutical industry that attracted currency crises due to its strong correlation with exchange market. The next point of contagion in the first currency crisis is investment industry, and in the second currency crisis, basic metals and oil products. It is suggested that when currency crisis occurred, investors increase weight of basic metals stocks and decrease share of pharmaceutical and computers in their portfolio.

The purpose of this study is to investigate the effect of boom and recession with energy prices on energy consumption (electricity, non-electricity and total) in Iran with an asymmetric method. For this purpose, for asymmetric analysis in the research model in three formats (based on total energy consumption, non-electricity and electricity) and five levels (total economy and household, commercial, public and industrial sectors) of asymmetric explanations, an nonlinesr autoregressive distributed lag approach has been used. Long-term results indicate that economic boom in every 15 estimates has a direct impact on energy consumption and in terms of size, in most cases, the elasticity of energy consumption relative to economic boom is greater than one. However, the recession is associated with a significant (and of course direct) effect in only 4 out of 15 estimates, and its impact is less than the economic boom. In the first format, at the level of the whole economy and at the level of the commercial, public and industrial sectors, production has an asymmetric effect, and at the household level, production has a symmetrical effect on total energy consumption. In the second format, at the level of the whole economy and at the level of the household, commercial and public sectors, production has an asymmetric effect and at the industry level, production has a symmetrical effect on non-electricity energy consumption. In the third format, at all five levels, production has an asymmetric effect on electricity consumption. The real energy price, although in ...

The main objective of this paper is to analyze empirically the effects of public investment on private investment, evaluating the existence of crowding-out/-in effects, in Iran for the 1970-2019 periods. I evaluate the macroeconomic effects of public and private investment through VECM analysis. From impulse response functions, we are able to assess the extent of crowding-in or crowding-out of both components of investment. I also compute the associated macroeconomic rates of return of public and private investment for Iran Economy. The results point to the existence of positive effects of public and private investment on output. On the other hand, results show the crowding-in effects of public investment on private investment. Based on these results, it is suggested that the government provide the conditions for private investment by creating infrastructure, helping to finance investment projects and creating a secure economic environment.
