    Driving down child mortality in the SAARC: the impact of GDP, healthcare, and vaccination
    (Springer Nature, 2025-09-25) Fernando, A; Sudangama, N; Adikari, D; Sundaram, A; Jayathilaka, R; Rajapakse, V
    This study investigates the determinants of under-five mortality rate (U5MR) in South Asian Association for Regional Cooperation (SAARC) countries from 2000 to 2020, focusing on the roles of per capita gross domestic product (PGDP), Diphtheria-Tetanus-Pertussis (DTP1) immunisation coverage, and government healthcare expenditure (GHE). Despite global progress in reducing child mortality, disparities persist in SAARC countries, where economic, healthcare, and immunisation factors influence child survival. The research employs a panel regression analysis using a fixed effects model to assess the impact of these variables on U5MR across seven SAARC nations (excluding Afghanistan due to insufficient and inconsistent data), as well as multiple linear regression (MLR) for a country-specific explanation. Results reveal that both PGDP and DTP1 coverage are inversely related to U5MR, highlighting the importance of economic growth and immunisation programs in reducing child mortality. However, while the associations between PGDP, GHE, and DTP1 with U5MR were not statistically significant in the panel model, the country specific MLR analysis revealed statistically significant relationships in some cases. In fact, GHE presents mixed results, indicating that healthcare expenditure alone may be insufficient without effective allocation. The study’s findings emphasise the need for region-specific policies to address healthcare inequalities and expand immunisation programs, providing practical recommendations for SAARC policymakers to achieve sustainable improvements in child health outcomes.

    Reviewing the Economics of Using LPG Vs. Electricity for Household Cooking in Sri Lanka
    (IEEE, 2020-11-16) Jayasekara, S; Fernando, Y. S
    Cooking is an essential activity in the households in Sri Lanka. Sri Lankan households utilize several types of fuel to produce heat for their daily cooking needs. The most commonly used energy sources are Liquid Petroleum Gas (LPG) and Electricity. Therefore, it is essential to investigate the economic aspects of using each of these energy sources. This research aims to use existing data on several cooking appliances along with LPG and Electricity charges in Sri Lanka to calculate the costs of using each of the energy sources. With the total monthly cost of LPG at Rs.560/= and Electricity at Rs.1150/= as of March 2020, this study suggests that LPG is the most suitable energy source for cooking in Sri Lankan households.
