    Dynamics of Poverty in Iran

    , M.Sc. Thesis Sharif University of Technology Mohammadzadeh, Ahmad (Author) ; Keshavarz Haddad, Gholamreza (Supervisor)
    Abstract
    Eliminating poverty, which is one of the most important objectives of countries, requires a deep understanding of the trends and dynamics of poverty and the distinction between chronic and transient poverty. However, given the lack of high-quality panel data, measuring movements in and out of poverty in developing countries is difficult. In this research, we build a synthetic panel by constructing a consumption model and estimating the first-round consumption of households surveyed in the second round. The analysis of Expenditures and Income Survey (HEIS) for 1398 and 1399 shows that almost 29 percent of urban and rural households were poor in both years. In female-headed households,... 

    Improving Artificial Neural Network Predictive Performance Using Panel Data

    , M.Sc. Thesis Sharif University of Technology Alirezaei, Hamid Reza (Author) ; Khedmati, Majid (Supervisor) ; Rafiee, Majid (Supervisor)
    Abstract
    The purpose of the present study is to develop neural network estimation method for hybrid or panel data which have a combination of two cross-sectional and time series structures and because of the features of both structures, their use in different sciences offers many advantages; and the analytical methods for this data structure are also different from other one-dimensional structures, so different and specific regression models are presented for this data structure. However, in the artificial neural network method, modeling the development for this data structure is neglected, so in the present study, using the concepts of panel regression methods and their application to the... 

    Determining Factors of Foreign Direct Investment Using Gravity Model

    , M.Sc. Thesis Sharif University of Technology Ebrahimi, Nima (Author) ; Abedini, Javad (Supervisor)
    Abstract
    Foreign direct investment (FDI) has considerably increased in recent years and achieved two percent of the world GDP in 2009. The positive impact of FDI on many national economic variables such as export and employment has been a great motivation for countries to seek it. In spite of many promoting factors in Iran, the Iranian FDI inflow still remains small. Using a huge panel dataset including 2604 real observations, this study aims to recognize and evaluate the impact of main factors influencing FDI inwards across the world. Based on a theoretical approach, we develop an empirical gravity model which includes not only the traditional mass variables but also some specific factors to FDI... 

    Long Term Effective Factors on House Price of Metropolises of Iran

    , M.Sc. Thesis Sharif University of Technology Moeeni, Safoura (Author) ; Nili, Masoud (Supervisor)
    Abstract
    The notable share of housing sector in GDP (approximately five percent) shows this sector’s relation with macroeconomic activities. On the other hand, House as an asset leads housing sector to be affected by monetary and fiscal variables. A dynamic panel data was used in this study to evaluate the relations between housing sector and some macroeconomic variables in metropolises of Iran. As results show, in long term growth of liquidity, GDP per capita and sharp ratio have positive effects, and land per capita has negative effect on housing price in metropolises of Iran. Price increases have not been equal in different cities. Inequality of land price between metropolises and between...

    Is There any Price Bubble in the Iranian Housing Market: a Structural Analysis Across Iranian Provinces Over 1375-1389

    , M.Sc. Thesis Sharif University of Technology Ebrahimi, Hassan (Author) ; Abedini, Javad (Supervisor)
    Abstract
    During the two last decades, Iranians have faced with a wide and substantial increase in housing prices, especially in great metropolitans such as Tehran, Mashhad, Isfahan and Shiraz. This easily could be refered to a hyperinflation which significantly impeded the access of low and medium income families to housing. This study uses a structure model to recognize the responsible factors of such a rise in housing prices and to show whether there is any price bubble in market. The model consists of both supply and demand side determinants to explain the price changes across Iranian provinces over 1375-1390, in a panel data context. In particular, we use a longer and larger database which also... 

    Structural Model of Real Exchange Rate with Emphasis on the Terms of Trade Effect

    , M.Sc. Thesis Sharif University of Technology Fahimifard, Hamed (Author) ; Abedini, Javad (Supervisor)
    Abstract
    Despite the relative weakness of exchange rate structural models in determination short term fluctuations, observations show that real exchange rate respond to some fundamental economic variables. Due to the growing foreign sector of national economies, recent studies pay special attention to the impact of terms of trade on currency exchange rate. In this study, a structural model of the real exchange rate between the 70 currencies and during the period 1980-2010 has been developed in the context of panel data. Empirical micro-founded model are based on theoretical general equilibrium. Important features of such study are stationary of variables and causality test. Determination the effect... 

    , M.Sc. Thesis Sharif University of Technology Abtahi, Mohammad Reza (Author) ; Abedini, Javad (Supervisor)
    Abstract
    In this piece of work, a gravity model is suggested as Iranian non-fuel export model to OIC countries. The most important results out of this model are the acquired coefficients of two variables, namely “ECO membership” and “Economic and Trade Freedom of Importer”. At first, we expected that for importer, being a member of ECO would increase the amount of trade with iran. Surprisingly, this is not what we see in a model. In fact, as ECO has not achieved any tangible success in increasing trade between its members, eastern Asian Muslim countries has become an important trade partner for iranians. This result is compatible with other pieces of researches about ECO. “Economic and Trade Freedom...

    Price elasticity of gasoline smuggling: a semi-structural estimation approach

    , Article Energy Economics ; Volume 71 , 2018 , Pages 171-185 ; 01409883 (ISSN) Ghoddusi, H ; Rafizadeh, N ; Rahmati, M. H ; Sharif University of Technology
    Elsevier B.V  2018
    Abstract
    We estimate the price elasticity of the demand for gasoline smuggling in Iran. For this purpose, we employ a detailed panel of monthly gasoline consumption data from 160 distribution hubs during the period 2005–2014. We apply two different approaches which are diff-in-diff and panel data estimations. The results suggest that the foreign-to-home gasoline price ratios have a significant impact on the time-varying elasticity of demand. This finding supports the hypothesis that an increase in domestic gasoline prices will significantly reduce the demand for smuggling. In addition, as the distance of a region from its closest higher-price neighboring country diminishes, the price elasticity of... 

    Estimation of the Price Elasticity of Gasoline Smuggling Demand in Iran

    , M.Sc. Thesis Sharif University of Technology Rafizadeh, Nima (Author) ; Rahmati, Mohammad Hossein (Supervisor)
    Abstract
    This study investigates the price elasticity of gasoline smuggling demand in Iran. For this purpose, a panel data of monthly gasoline consumption has been used that contains data for 160 regions of distribution for Iran's Oil Production Company between 2005 and 2014. The results of estimating the monthly elasticity of gasoline smuggling demand in each region show a significant impact of the gasoline price differential between Iran and its neighboring countries, as well as the distance of each region with the neighboring countries on the demand. The results of this study show that whenever gasoline prices increase inside the country, the inclination to smuggling has been decreased due to a...

    The Effects of Oil Wealth on the Protection of Property Rights in the Oil Countries

    , M.Sc. Thesis Sharif University of Technology Dashtimanesh, Mohammad Javad (Author) ; Nili, Masood (Supervisor)
    Abstract
    Using a panel dataset of oil discoveries and oil prices, this thesis studies the effect of oil wealth on protection of property rights in 56 oil countries between 1995 to 2018. Controlling for year fixed effects and country fixed effects, We show that this association is affected by the ownership of oil in this countries. In countries that government is owned all the oil industry, a strong correlation is observable between oil wealth and property rights policies. But in countries that private ownership on oil is legal and the government is not monopolist in the oil ownership, this correlation is insignificant. This results are robust with controlling the GDP per capita, political regime... 

    Intergenerational Social Mobility In Iran

    , M.Sc. Thesis Sharif University of Technology Nazari Amnie, Mojtaba (Author) ; Keshavarz Haddad, Gholamreza (Supervisor)
    Abstract
    This research studies intergenerational social mobility in Iran using the data from Household Income and Expenditure Survey (HIES) from 1377 to 1399. In the absence of long-term panel data or intergenerational cross-sectional data in which there are some variables connecting people to their parents, the method used here to measure welfare mobility -as a suitable proxy of social mobility- is the synthetic panel method. To use this method, it is assumed that the samples are similar in the two selected stages and they can be related to each other with fixed characteristics such as age and gender. The output of the method is an intergenerational transition matrix that shows the probability of a...

    , M.Sc. Thesis Sharif University of Technology Babaei, Arash (Author) ; Keshavarz Haddad, Gholamreza (Supervisor)
    Abstract
    Due to its extensive applications in financial analysis, stock market volatility modeling is a considerably important issue for stock market practitioners and academics. Using GARCH models to formulate the conditional variance heteroskedasticity with respect to the advantages of panel data technique such as higher degrees of freedom, more flexibility in the control of the omitted or unobserved variables effects, lead to a significant increase in the accuracy of estimations. In this thesis, in order to examine the similarities and differences between the conditional variance structure of stocks in the inter and intra industries, we have used a general to specific methodology of nested tests...
