    Analysing the Effects of Monetizing Energy Carriers Subsidy on Expenditures and Welfare Criteria of Iranian Households

    , M.Sc. Thesis Sharif University of Technology Einian, Majid (Author) ; Fatemi, Farshad (Supervisor)
    Abstract
    In this thesis, with a review on policy simulation and economic reform analysis literature, we design a suitable method to analyze the effects of monetizing energy carriers subsidy on welfare criteria of Iranian households. The selected method is limited general equilibrium that needs demand estimates of goods, services and energy. In firs step,based on 13 years of data on “Iranian Households’ Expenditures and Income” surveys, data are provided as a pseudo-panel. Demand equations are estimated using “Seemingly Unrelated Regressions” for panel data, and elasticities are calculated. In the next step, we evaluated the equivalent variation and equivalent gain measures in each price scenarios.... 

    Adverse Selection in Iranian Life Insurance Market

    , M.Sc. Thesis Sharif University of Technology Mirtaher, Abdolkarim (Author) ; Fatemi, Farshad (Supervisor)
    Abstract
    This thesis finds evidence for the presence of adverse selection in the Iranian life insurance market. We use a unique dataset including more than one million policyholders’ profile information alongside their chosen life insurance coverage from the largest Iranian insurance company. Our results not only find evidence in support of adverse selection in this market, but also consider the magnitude of adverse selection relatively notable. Moreover, we found that in addition to the coverage, the other dimensions of contract could be the potential source of adverse selection. Particularly, we focused on the insurance duration and the payment method (monthly, annually, all-in-advance).... 

    Analysis and data-based reconstruction of complex nonlinear dynamical systems : using the methods of stochastic processes

    , Book Rahimi Tabar, M. Reza
    Springer International Publishing  2019
    Abstract
    This book focuses on a central question in the field of complex systems: Given a fluctuating (in time or space), uni- or multi-variant sequentially measured set of experimental data (even noisy data), how should one analyse non-parametrically the data, assess underlying trends, uncover characteristics of the fluctuations (including diffusion and jump contributions), and construct a stochastic evolution equation?
    Here, the term "non-parametrically" exemplifies that all the functions and parameters of the constructed stochastic evolution equation can be determined directly from the measured data.
    The book provides an overview of methods that have been developed for the analysis of... 

    Analyses of Effect of Bank Branching on Deposit Market Share and Market Size in Iran Banking Industry

    , M.Sc. Thesis Sharif University of Technology Yousefi, Fateme (Author) ; Fatemi, Farshad (Supervisor)
    Abstract
    This thesis aim to the study of the effect of bank’s branching decisions on deposit market. Using panel data banks from Iran, we study effect of branching on market share and market size. In theoretical part, we assume that banks maximize discounted flow of the profits. We also assume that the banks take into account the reaction from rival banks in setting number of branches. Banks are assumed to expect the rival banks react by a lag of one period. In empirical part, in order to distinguish between aggregate market size effect and market share effect, we rewrite quantity of deposit in banks as the product of aggregate deposit and market share. We specify deposit market share function with... 

    Investigation of Hamrahe-Aval Demand Services

    , M.Sc. Thesis Sharif University of Technology Hosseinabadi, Mahsa (Author) ; Fatemi, Farshad (Supervisor)
    Abstract
    In the past few years mobile usage is increasing in Iran. Since mobile industry is growing and new innovations are presented, the competition between operators is rising. Although this competition has a great influence on the mobile demand for each operator, lack of the data of the all operators made us to use the data of one of the operators to investigate the demand. Based on the subscriber’s data of Hamrahe-Aval company, it has been introduced an estimation of a demand system for customers of this company by using AIDS model in this essay. This model includes three groups of services: sending short messages, calling to mobile numbers and calling to fixed numbers.
    This study has two... 

    The Static and Dynamic Relationship between Monetary and Multidimensional Poverty Approaches

    , M.Sc. Thesis Sharif University of Technology Goodarzi, Marzieh (Author) ; Fatemi Ardestani, Farshad (Supervisor)
    Abstract
    The identification of the poor and the elimination of their poverty always has been the subject of discussion among researchers and policymakers. Today, most researchers consider poverty as a multidimensional phenomenon, and in addition to income indicator, it has indicators related to the level of knowledge, awareness, well-being and the health of individuals. The study of multidimensional poverty and the search for the discovery of its static and dynamic relationship with income-based poverty is the subject of this research. The analysis shows that both statically and dynamically, there is a substantial mismatch in the identification of the poor households according to these two... 

    Does Childbearing Behavior of the Parents Confirm the Existence of Gender Preference in Iran?

    , M.Sc. Thesis Sharif University of Technology Hassanshahi, Hanieh (Author) ; Fatemi, Farshad (Supervisor)
    Abstract
    Since the mid-twentieth century, the issue of gender preference has always been of interest to economists. This preference is demonstrated by sex-selection methods such as differential stopping behavior and sex-selective abortion. While it is almost impossible to look directly into abortion behavior in Iran, due to religious beliefs and illegality, we can investigate gender preference by calculating to what extent parents adapt their fertility behavior to ensure the birth of preferred sex. For this purpose, we use “Households Income and Expenditure Survey of 2019” data from the Statistical Center of Iran. Our results indicate that when Iranian parents are deciding to have second child, they... 

    Tipping Cascades in Complex Networks: Dynamics and Control

    , M.Sc. Thesis Sharif University of Technology Shahrabi, Ali (Author) ; Rahimi Tabar, Mohammad Reza (Supervisor)
    Abstract
    Tipping points occur in diverse systems in various disciplines such as ecology, climate science, economy, sociology, and engineering. Critical thresholds in system parameters or state variables at which a tiny perturbation can lead to a qualitative change in the system exist in many subsystems in complex systems. These thresholds are called tipping points, and these subsystems are called tipping elements. Additionally, many systems with tipping points can be modeled as networks of coupled multistable subsystems. Domino-like tippings are called tipping cascades. Considering that these tipping cascades are primarily unprecedented, it is essential to study the dynamics and control of these... 

    Investigating Sex Preferences in Iran

    , M.Sc. Thesis Sharif University of Technology Khatib Shahidi, Milad (Author) ; Fatemi, Farshad (Supervisor)
    Abstract
    The question of whether sex preferences are present in a certain country has long been of interest for economists and demographers. This study first investigates the existence of these preferences among Iranian parents. Next, if any preference are present, it turns to the task of inferring the quality of the observed preferences. There are two widely used methods for addressing these issues in the literature. The first method is to estimate a Logit model which relates the probability of a mother giving birth to a new child, to the sexes of her previous children. The second one is to estimate a Proportional Hazard model in order to investigate the relationship of the time interval between... 

    Physician Induced Demand Case Study of Caesarean Section in Iran

    , M.Sc. Thesis Sharif University of Technology Khani, Mohammad (Author) ; Fatemi Ardestani, Farshad (Supervisor)
    Abstract
    In standard models, the demand function is considered to be independent from the supply function and the intersection of these curves is considered to determine the price and quantity in the market. The alternative model, called “inducement hypothesis”, describes how the supply side can persuade consumers through particular advices, induce demand for the provided services and though shift the demand curve; i.e. demand is not independent from supply. For the case of physicians, this hypothesis is known as “physician induced demand”. In fact, this theory describes the supply-side moral hazard in the production market. This hypothesis may have vast applications which are different from... 

    Investigating Effective Determinants of Driving Offences in Iran

    , M.Sc. Thesis Sharif University of Technology Aboohamzeh, Dariush (Author) ; Fatemi Ardestani, Farshad (Supervisor)
    Abstract
    In Economic literature, investigating effective determinants of driving offences is discussed in Economics of Crime. In this field the effect of economic and sometimes non-economic parameters on offences are investigated. Economics of Crime was introduced as a branch of economics after Becker (1968). Since then different studies have been done and many theories have been made to discuss the relation between economic Variables and crimes in the society. In this study we use a cross-province panel data of driving offences to investigate the Effective Determinants of these offences. The most important result is the deterring effect of the penalty. For example in the regression for the seventeen... 

    Evaluation of Gender Discrimination in the Allocation of Educational Expenditure in the Iranian’s Household

    , M.Sc. Thesis Sharif University of Technology Gharakhanlo, Mahtab (Author) ; Fatemi Ardestani, Farshad (Supervisor)
    Abstract
    In the past few decades a range of human capital theories were developed by economists. In all these, education and training are considered as a prominent aspect of the human capital. Among all influential factors on the education, the role of the family in the allocation of educational expenditure is one of the most important factors. In this research, we investigate whether in gendr discrimination among sibiling is observed in Iranian households. Based on household budget data, we estimate the Engel curve in order to investigate the gender discrimination in the allocation of educational expenditure. Families divided into 6 clusters based on the composition of their children and the tests... 

    Investing Parent’s Preferences on Quality and Quantity of Their Children: a Case Study of Iranian Society, from 1385 to 1390

    , M.Sc. Thesis Sharif University of Technology Demneh, Niloufar (Author) ; Fatemi Ardestani, Farshad (Supervisor)
    Abstract
    This thesis aims to the study of quality-quantity trade off in the family through investigating the effects of family size and birth order on their educational attainment. The latter has been chosen as a criteria for measuring the quality; to measure the effects of quantity we have used the twins for the instrumental variable as an endogenous shock in the family size to reduce bias that happens as a result of omitted variables bias and to measure the effect of family size on it’s quality more accurately. We have also used censored regression to eliminate the bias of student children in the sample.In addition to concentrating on the differences between children of different family sizes we... 

    Market of Kidney in Iran

    , M.Sc. Thesis Sharif University of Technology Didgar, Dadmehr (Author) ; Fatemi Ardestani, Farshad (Supervisor)
    Abstract
    In this study we developed an analytical model to delve into the behavior of participants in the market of kidney in Iran. We get health as a good which not only elevates the utility of any individual, it add more years to each individual longevity. We find out that ESRD patients who are in serious need of receiving a new kidney will never postpone buying kidney in case of having the price fixed in all periods.We found out that the waiting time in queue of receiving market is a u-shape function in which there is a minimum. We proved that the price making the queue minimum is definitely bigger than the market clearance market. Accordingly, despite all the unfair and immoral view toward... 

    Mineral Rights Auction’s Valuation Paradigms: Case Study, The Gulf of Mexico

    , M.Sc. Thesis Sharif University of Technology Yadegari, Ali (Author) ; Fatemi Ardestani, Farshad (Supervisor)
    Abstract
    Auction literature and economic theories advocate common valuation among bidders in mineral rights auctions. In this study, we have tried to examine the assumption of common valuation between bidders in a first price sealed bid auction. It examines the common valuation hypothesis by assuming the information symmetry and the exogenous entry of bidders. The findings of this study suggest that bidders’ valuation in a first price sealed bid auction of natural resources may be private or common value. We use the non-parametric estimation model to find that after the federal government imposed Area-wide Leasing in the Gulf of Mexico, bidders’ valuations changed from private valuation to common...

    Capabilities, difficulties and obstacles for energy recovery from MSW’ as a sustainable option for waste management in Iran

    , Article WIT Transactions on Ecology and the Environment ; Vol. 186 , 16-18 December , 2014 , pp. 789-798 ; ISSN: 17433541 ; ISBN: 9781845648374 Rahimi, E ; Sharif University of Technology
    2014
    Abstract
    Increasing concerns about unbridled fossil fuel consumption and a growing generation of municipal solid waste (MSW) in Iran and related environmental challenges require adoption of more sustainable approaches in energy and waste management. Energy recovery from waste can play an important role to achieve environmentally sustainable development that has been defined for the country as a main policy. Iran’s growing urban population generates massive amounts of MSW that mostly end up in landfills. A population of 75 million is generating 50,000 tonnes of MSW every day that mostly are buried in landfills. Detrimental emissions from landfills and many other long-lasting environmental issues have... 

    Hedonic Analysis of Land Price Case Study in Tehran, Zone 8

    , M.Sc. Thesis Sharif University of Technology Saharkhiz, Morteza (Author) ; Fatemi, Farshad (Supervisor) ; Barakchian, Mahdi (Supervisor)
    Abstract
    The land market is one of the most important markets in the economy. Land is a factor of production, store of value, and a major part of household’s portfolio. Although price of land is an essential information for institutions like municipalities whom tax the landlords, or for financial intermediaries like banks whom use the land as collateral, studies about price of land and its spatial and time variations are scrace in Iran. Furthermore, most of studies in other countries are usually based on inflexible OLS estimators. Thus, this study has two main contributions. First, to analyze the usefulness of hedonic modeling in explaining the price of land, utilizing a unique dataset for Tehran...
