    Background: Comprehensive and comparable estimates of health spending in each country are a key input for health policy and planning, and are necessary to support the achievement of national and international health goals. Previous studies have tracked past and projected future health spending until 2040 and shown that, with economic development, countries tend to spend more on health per capita, with a decreasing share of spending from development assistance and out-of-pocket sources. We aimed to characterise the past, present, and predicted future of global health spending, with an emphasis on equity in spending across countries. Methods: We estimated domestic health spending for 195...

    , Article Journal of Economic Studies ; Volume 46, Issue 1 , 2019 , Pages 228-244 ; 01443585 (ISSN) Keshavarz Haddad, G ; Habibi, N ; Rafiee, S ; Sharif University of Technology
    Emerald Group Publishing Ltd  2019
    Purpose: The purpose of this paper is to examine cigarette consumption behavior of younger cohorts in the urban and rural areas of Iran. The authors use Iran’s annual Household Income and Expenditures Surveys (HIES) database over 2007–2013 for the statistical analysis. In order to control for a large number of households with zero expenditure on cigarette consumption, the authors have used the double-hurdle modeling approach for counting the outcomes of interest. The authors have also limited the sample to cases in which the head of household is between the ages of 21 and 45 and all children are younger than 18. Design/methodology/approach: In this study, the authors have conducted a... 

    Energy-efficient fast configuration of flexible transponders and grooming switches in OFDM-based elastic optical networks

    , Article Journal of Optical Communications and Networking ; Volume 10, Issue 2 , 2018 , Pages 90-103 ; 19430620 (ISSN) Hadi, M ; Pakravan, M. R ; Sharif University of Technology
    Institute of Electrical and Electronics Engineers Inc  2018
    We investigate the problem of energy-efficient resource allocation constrained to quality of service and physical requirements in orthogonal frequency division multiplexing (OFDM)-based elastic optical networks and propose a fast two-stage algorithm to solve it. The first stage of the proposed algorithm deals with routing, traffic grooming, and traffic ordering and mainly aims at minimization of the number of deployed optical amplifiers and transponders. We provide an integer linear program for routing and traffic grooming and propose a heuristic procedure, which yields its near-optimum solution in a shorter runtime. In the second stage, we optimize transponder parameters to minimize total...

    Elsevier Inc  2016
    The debate over innovativeness of large firms and SMEs, which was bolded by Schumpeter, still continues under mixed empirical evidences. There are several implications for this debate including policy orientation in support of large firms or SMEs. But there is a scarce of studies in developing countries and no such study in Iran yet. The present study has explored the proportionality of increase of innovation activity versus firm size within 522 Iranian knowledge-based firms categorized in 9 industries. Innovation activity was measured by R&D expenditure while firm size stood for number of employees. Using log-log regression in the first phase, it was found that R&D expenditure confirms a... 

    A technical and economic assessment of variants for CO2 separation from synthesis gas

    , Article Energy Sources, Part B: Economics, Planning and Policy ; Volume 11, Issue 12 , 2016 , Pages 1097-1102 ; 15567249 (ISSN) Amini, E ; Nouri Khorasani, A ; Baghalha, M ; Pazos Costa, A ; Sharif University of Technology

    An analysis of carbon dioxide (CO2) removal process from synthesis gas has been carried out in this work. CO2 removals by physical and chemical solvents are the most often used. The most important factors that affect cost and performance of a CO2 recovery unit are the number of flash drum separation units, and the pressure drop pattern among them. Different variations of this process were simulated using Hysys software, and the capital and operational expenditures for these plants were estimated. The focus was to reach an optimum process to minimize the total unit cost of separated CO2. The results indicate that for a fixed number of separation units, the case with uniform pressure drop...

    SAGE  2012
    Paraplegic users of mechanical walking orthoses, e.g. advanced reciprocating gait orthosis (ARGO), often face high energy expenditure and extreme upper body loading during locomotion. We studied the effect of kinematical pattern on the mechanical performance of paraplegic locomotion, in search for an improved gait pattern that leads to lower muscular efforts. A three-dimensional, four segment, six-degrees-of-freedom skeletal model of the advanced reciprocating gait orthosis-assisted paraplegic locomotion was developed based on the data acquired from an experimental study on a single subject. The effect of muscles was represented by ideal joint torque generators. A response surface analysis... 

    Intergenerational Social Mobility In Iran

    , M.Sc. Thesis Sharif University of Technology Nazari Amnie, Mojtaba (Author) ; Keshavarz Haddad, Gholamreza (Supervisor)
    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... 

    An Investigation on the Size and the Welfare of Different Income Groups During 1376-1399 and an Estimation of the Mobility of the Iranian Urban Low-Income Households

    , M.Sc. Thesis Sharif University of Technology Ghaderi, Alireza (Author) ; Nili, Masoud (Supervisor) ; Mohaghegh, Mohsen (Supervisor)
    In this study, based on Households Income and Expenditure Survey (HIES) data, we examined the socio-economic characteristics and transition of Iranian urban households in each of the three different income groups from 1997 to 2020. Moreover, factors affecting entry to poverty or persistence in poverty in Iranian urban households are discussed.The results of this study show that, contrary to popular belief, there is no evidence of accumulation of entrepreneurs and business owners in the urban middle class. Rather, middle-income households have higher-skilled jobs and pay more for social security than low-income ones, as well as pay more attention to investing in human capitals (education and...

    The provision of developmental infrastructure by governments and their various effects on the lives of citizens has always been the subject of discussion among researchers and policymakers. In particular, the infrastructure associated with access to modern energies causes changes in household economic behavior. The effects of pipeline gas connection on household behavior is the main subject of this research. By using micro level data, these effects compare the behavior of beneficiary households and lack of natural gas. The data includes households living in the entire geographical zone of Iran and between 1377 and 1394. First, we show that natural gas is a direct substitute for liquid fuels... 

    A System Dynamics Approach to Understanding the Dynamics of the Increase of Health Expenditures Share of GDP in Germany

    , M.Sc. Thesis Sharif University of Technology Ebrahimi, Kasra (Author) ; Mashayekhi, Alinaghi (Supervisor)
    The main question of this research is this: what mechanisms drive the increase of the share of health costs in GDP in Germany? Answering this question not only improves our understanding about health systems in general, but also is specifically useful for the health system of Iran, since it is experiencing similar trends as the health system of Germany does. Since these mechanisms are complex and the ability of human brain to process several interacting variables simultaneously is low, we need a strong methodology and a tool to overcome this limitation. System thinking as a methodology and system dynamics as its tool help us do so. Using system dynamics, we will develop a computer model... 

    Impact of Inflation on Household’s Saving within the Framework of Expenditure System

    , M.Sc. Thesis Sharif University of Technology Mohsenirad, Saman (Author) ; Nili, Masoud (Supervisor)
    In this thesis the impact of inflation on urban household saving is investigated. For calculating sensitivity of saving respect to price changing of different groups of commodities, firstly we divided household cost to two separated groups of durable and nondurable and then by defining total income as summation of monetary and nonmonetary income of households, We consider saving as total income minuses nondurable consumption. Finally we estimated the “Extended Linear Expenditure System” model base on the prepared data. Since inflation is result of unequal changes in prices of goods and services, the approach of expenditure system allows us to assess unequal changes in prices for eight...
