  • 1.00pm: Muhammad Irfan: Households’ fuel selection in Pakistan
  • Almost 2.7 billion people worldwide depend on traditional or conventional energy sources for cooking, heating, and lighting. By 2030 this number is projected to rise to 2.8 billion. These solid fuels are a major cause of indoor air pollution and can severely damage health and the environment, yet the use of solid fuels is very common in developing countries such as Pakistan.

    This study analyzes the Pakistan Social and Living Standards Measurement (PSLM) Survey 2013-14 data to establish the factors behind the fuel mix selection of households.

    We found that income, education, and urban area are strong factors associated with clean fuel consumption; while agricultural occupation, large family size, cattle, and agricultural land are associated with the solid fuel consumption.

    The study suggests that clean fuels should be subsidised, and the government of Pakistan should disseminate information about the health effects associated with indoor air pollution.

  • 1.30pm: Ngoc Thi Minh Tran: International migration and Institutional quality in the home country:  Where you go and how long you stay matters.
  • International migrants are widely known as agents of institutional change in their home countries. However, the huge growth in temporary migration in recent years demands a fresh investigation of this phenomenon. A core factor enabling the transnational influence of diasporas is their retained connection to home countries.

    This paper exploits the Database on Immigrants in OECD Countries (DIOC) to investigate the influence of diasporas living in OECD countries on institutional quality in home countries, and takes into account the heterogeneity of diasporas’ duration-of-stay composition.

  • 2.00pm: Omoniyi Alimi: More pensioners, less income inequality? The impact of changing age composition on inequality in big cities and elsewhere

    New Zealand's population is ageing both numerically and structurally. Population ageing can have important effects on the distribution of personal income within and between urban and metropolitan areas.

    New Zealand has experienced a significant increase in income inequality over the last few decades, but population ageing has slightly dampened this trend. 

    By decomposing New Zealand census data from 1986 to 2013 by age and urban area, this study examines the effects of population ageing on spatial-temporal changes in the distribution of personal income to better understand urban area-level income inequality.

  • 2.30pm: Yun Liang: Do more grandchildren lead to worse health status of grandparents?  Evidence from CHNS data
  • China's social security system does not provide sufficient pension coverage for its rapidly ageing population. As a result, nearly 80% of people aged 85 and older depend on their children or other relatives for financial support.

    We use China Health and Nutrition Survey data to test if grandchildren adversely affect the health of the elderly. This could occur because grandparents and grandchildren compete for financial support from the working adults in a family, or because grandparents often have to care for young grandchildren and may neglect their own health.
