    Status Quo Bias and EV Adoption: A Prospect Theory Perspective from a Developing Country Context
    (Multidisciplinary Digital Publishing Institute (MDPI), 2026-04-01) Theekshana, D; Gamage, K. A.A; Herath, R; Kavirathna, C.A; Jayasinghe, S; Weerakkody W.A.S
    Electric vehicles (EVs) are promoted to decarbonise road transport, yet uptake remains slow in many emerging markets. This study examines consumer resistance to EV adoption in Sri Lanka by modelling status quo bias (SQB) using a Prospect Theory lens. An online survey of urban vehicle owners and near-term buyers yielded 157 responses; after screening and removing influential outliers, 151 cases were analysed using partial least squares structural equation modelling (PLS-SEM). The model tests five Prospect Theory-aligned antecedents, namely, loss aversion, reference dependence, risk perception, framing effects, and uncertainty aversion, and evaluates environmental concern as a moderator. Results indicate that loss aversion has a significant positive effect on SQB (β = 0.216, p = 0.005) and uncertainty aversion is the strongest predictor (β = 0.453, p < 0.001), while reference dependence, risk perception, and framing effects show positive but statistically non-significant direct effects. Moderation tests show that environmental concern significantly moderates the effects of reference dependence (β = 0.181, p = 0.039) and framing effects (β = 0.179, p = 0.037) on SQB, but does not significantly moderate the loss aversion, risk perception, or uncertainty aversion paths. Overall, perceived losses and—especially—ambiguity surrounding EV ownership appear to sustain reliance on internal combustion vehicles in this developing-country context, underscoring the need for interventions that reduce uncertainty (credible infrastructure signals, stable policy, servi

    E-commerce success redefined: integrating information systems and customer empowerment for e-customer engagement
    (Emerald Publishing, 2026-03-17) Boyagoda, G; Thalagala, S.M; Pathirana, S.L; Jeewantha, S; Wisenthige, K
    Purpose – This study aims to explore the impact of system quality, information quality, service quality and customer empowerment on customer satisfaction and e-commerce success in Sri Lanka, focusing on Millennials and Generation Z. By integrating the DeLone and McLean Information Systems Success (D&M ISS) model with customer empowerment theory, the research seeks to provide insights into the key drivers of e-customer engagement in e-commerce. Design/methodology/approach – A structured questionnaire was used to collect data from 413 respondents employing the purposive sampling technique. The data collection instrument comprised 32 questions related to system quality, information quality, service quality, customer empowerment and customer satisfaction, as well as demographic questions. The data were analysed using Partial Least Squares Structural Equation Modelling (PLS-SEM). Findings – The results revealed that the system quality, information quality and service quality significantly influence customer satisfaction and intention to use the system in the context of e-commerce, which leads to higher customer engagement. Furthermore, the findings substantiate the crucial role that customer empowerment plays in terms of increasing customer satisfaction. Research limitations/implications – This study focuses on Millennials and Generation Z e-customers in Sri Lanka. It provides insights into this demographic, but does not capture the diverse cultural and technological landscape of the entire country. The study examines Information System (IS) dimensions and customer empowerment, excluding other significant variables like overall customer engagement. Self-reported data may introduce biases, and future research with larger sample sizes and different methods could improve the validity. Focusing on four selected online shopping platforms may limit the applicability as the e-commerce landscape is continuously evolving. Practical implications – The findings offer guidance to e-commerce businesses and policymakers to enhance their digital services and customer satisfaction. Businesses can improve their system quality with intuitive designs, offering accurate information to boost engagement and deliver excellent service quality. Initiatives such as interactive tools, loyalty programs and tailored support can empower customers, fostering a stronger impact. Policymakers can support e-commerce growth by improving regulations and providing training programs. These measures contribute to a more efficient and satisfying online shopping experience, driving long-term customer loyalty and business growth. Social implications – The research emphasises the role of customer empowerment in fostering customer engagement, contributing to the growth of the digital economy and enhancing online shopping experiences. Originality/value – This research enhances the academic understanding of e-commerce success by strengthening the DeLone and McLean Information Systems Success model by adding the concept of customer empowerment. This unique improvement is applied in the context of Sri Lanka, an emerging market with its own socio-economic characteristics. This addition provides new insights into key factors affecting e-customer engagement in the e-commerce sector.

    Focus on Middle East and Central Asia: rationale of IMF assistance seeking
    (Springer Science and Business Media Deutschland GmbH, 2026-03) Wisenthige, K; Pathiranage, H. S.K; Jayathilaka, R
    This study delves into the rationale behind the tendency of nations in the Middle East and Central Asia (MECA) to seek aid from the IMF. The IMF supports global financial stability, aiming to foster economic growth and prosperity across its member countries by promoting policies that encourage monetary cooperation and financial resilience. The study employs a conditional fixed-effects logit model, the analysis spans 22 years of data from twenty-five MECA countries to identify the factors driving these nations to seek IMF assistance. It focuses on six determinants: Current Account Balance (CAB), Inflation (INF), Corruption (CORR), General Government Net Lending and Borrowing (GGNLB), General Government Gross Debt (GGGD), and Gross Domestic Product Growth (GDPG). The fixed-effects logit shows that slower GDP growth raises the odds of an IMF programme, while short-run changes in corruption control and public debt ratios are not significant once country and year effects are absorbed. Inflation is weakly positive; the current account balance is still insignificant. A post-GFC and an income-group robustness check confirm the pattern. Furthermore, the study identifies Lebanon, a lower-middle-income country, as a leading example of seeking IMF assistance during the study period. Overall, this research highlights the importance of policymakers understanding the dynamics and rankings within the MECA region to effectively address economic challenges, provide financial support, and foster a more sustainable economic structure.

    Achieving zero hunger: A global policy lens on food security drivers and income group disparities
    (Elsevier B.V., 2026-03) Pulle, N; Sampath, P; Perera, S; Wijayaweera, D; Jayathilaka, R
    Many countries struggle to meet their daily dietary requirements despite numerous attempts to address the existing demand. Consequently, this study collectively analyses the impact of urbanisation, renewable energy, greenhouse gas emissions, population growth, gross domestic product per capita and agricultural land on food production relying on Sen's Entitlement Theory, thus providing insights to resolve the long-standing issue of food insecurity, and support the achievement of the Sustainable Development Goals. The study utilises a stepwise panel ordered Probit model on 146 countries, for the years 1993 to 2023. It further categorises the food production index into three categories of food security as; low, moderate and high, thereby enabling discussion of the likelihood of a country falling into one of the aforementioned food security categories over the years. Urbanisation, agricultural land, and the dummy variables introduced to represent the income groups have been identified to have a significant and favourable relationship with the food production index. In contrast, the greenhouse gas emissions and renewable energy variables have a significantly inverse impact on the food production index. This makes a unique contribution to the existing body of literature, especially by comparing odds over the years, across different food secure categories, countries, and their specific income levels. This study enables policymakers to gain a comprehensive historical perspective on each case. This study further promotes the Sustainable Development Goals, highlighting areas where these goals have been negatively impacted. Additionally, the study discusses optimised investment allocations, agricultural research and development, agricultural technology, climate resilient farming, and sustainable urbanisation planning as solutions for extreme cases.

    Expanding STEM education in low- and middle-income countries: Evidence from policy reforms in Sri Lanka
    (Elsevier Ltd, 2026-03-01) Priyadarshana, I
    Governments in low- and middle-income countries (LMICs) are increasingly investing in STEM education to enhance youth employability and economic growth. Yet, the success of such initiatives depends on students’ responses, which are shaped by their perceptions, motivations, and institutional context. This study examines the effectiveness of two parallel government interventions in Sri Lanka aimed at increasing high school enrollment in STEM subjects: (1) introducing a new Technology stream and (2) upgrading selected schools to offer the Science stream. Using nationwide school census data from 2008 to 2021 and a Difference-in-Differences approach, the study compares the impacts of these interventions on student enrollment patterns across STEM and non-STEM majors. The results show that the introduction of the Technology stream had a significantly larger impact on increasing STEM enrollment and reducing non-STEM enrollments—especially among male students and those in provincial schools—compared to the Science stream intervention. The study draws on education economics and psychological theories to explain these differences, highlighting the roles of perceived returns, self-efficacy, and student interest orientation. The findings underscore the need for STEM policies to align with both student characteristics and broader systemic structures. Insights from Sri Lanka may be relevant to other LMICs where educational reforms must navigate stratified school systems, constrained resources, and persistent gender disparities in STEM participation.

    Assessing the influence of diverse skills on employability outcomes for IT undergraduates
    (Public Library of Science, 2026-04-10) Senadheera, D; Wisenthige, K
    Rapid technological advancements have reshaped the global job market, emphasizing the importance of specialized competencies such as user interface (UI) and user experience (UX) design, alongside technical and interpersonal skills.. This study examines how UI/UX skills (UIUX), soft skills (SS), and technical skills (TS) influence the employability (EP) of IT undergraduates in Sri Lanka, addressing a notable gap in existing literature that often examines these competencies in isolation and predominantly within Western contexts. The current study offers a detailed examination of employability determinants in Sri Lanka’s IT sector by incorporating gender as a moderating factor and investigating the mediating roles of self-efficacy (SE) and proficiency levels (LP). The collection of data involved 345 IT undergraduates participating in structured surveys, which were subsequently analyzed using partial least squares structural equation modelling (PLS-SEM). The results demonstrate that gender significantly affects the relationship between soft skills and technical skills with employability, underscoring differences in the assessment of these competencies among different genders. Moreover, the degree of proficiency influences the connection between technical skills and employability, yet it does not play a significant mediating role in the relationship between soft skills and UI/UX employability. Self-efficacy has proven to be a significant mediator across various skill categories UI/UX, soft, and technical highlighting its essential function in converting competencies into career success. This work seeks to add to existing knowledge by tackling the main significant gap of examining the combined effect of UI/UX, soft, and technical skills on employability. This study contributes to the theoretical understanding of employability by presenting an integrated model that elucidates the complex interactions among skills, mediators, and gender within the Sri Lankan IT sector. The results provide actionable insights for educators, policymakers, and industry leaders, advocating for curriculum alignment with industry needs and the promotion of self-efficacy through mentorship and experiential learning.

    Dynamic linkages between chicken meat production, consumption, income and trade: Evidence from Wavelet coherence and Granger causality in Asia
    (Elsevier Inc., 2026) Silva, Y; Susan, H; Perera, N; Mendis, K; Jayathilaka, R; Dabare, U
    The poultry industry has become one of the fastest-growing agricultural sectors in Asia, driven by rising incomes, and shifting food preferences. Therefore, this study aims to examine the relationship between chicken meat production and key determinants, including chicken meat consumption, gross domestic product, and trade openness, over 30 years (1993-2022) across 28 Asian countries. This study's foundation was based on the theories of consumer demand and international trade. Wavelet coherence and Granger causality analysis were utilised to identify the direction of causality of the variables. The Wavelet results reveal that chicken consumption and GDP become most significant with the production in the Asian continent, while Granger results reveal that most Asian countries showed unidirectional causal flows from trade openness to chicken meat production and from chicken meat production to gross domestic product and consumption. Furthermore, this study provides novel insights that inform policy considerations for policymakers, international and domestic organisations, and governments, aligning with the Sustainable Development Goals established by the United Nations.

    Global economic uncertainty shocks and macroeconomic dynamics before and after COVID-19: Evidence from Africa and the Americas
    (Elsevier Inc., 2026-04-03) Madurawala, R; Navamohan, P; Gamage, D; Hansika, S; Jayathilaka, R
    Global economic uncertainty has become a central driver of macroeconomic instability, particularly during large-scale crises like the COVID-19 pandemic. This study examines how global uncertainty shocks affect key macroeconomic variables, particularly suicide rates, economic growth, unemployment, and trade openness across 62 countries in Africa, South America, and North America over the period of 2004–2023 as the countries in these regions exhibit the highest uncertainty post-pandemic. Utilising the COVID-19 pandemic as a natural experiment, the analysis distinguishes between pre- and post-pandemic uncertainty-socioeconomic dynamics to assess the bidirectional and cointegrating relationships across regions. The study employs Multiple Linear Regression to capture short-term macroeconomic responses and panel and country-level cointegration techniques to identify long-run relationships between economic uncertainty and macroeconomic variables. Global uncertainty is proxied using the World Uncertainty Index, which captures broad policy, geopolitical, and crisis-related uncertainty affecting expectations and real economic activity. Unlike, existing studies which reveal insights in a particular region or country, the current findings uncover bi-directional relationships in 21 countries post-pandemic, with notable relationships in Algeria, Botswana, Gabon, Guinea, Madagascar, Republic of Congo, Dominican Republic, Mexico, Bolivia, Paraguay. Moreover, long-run cointegration between uncertainty and macroeconomic indicators strengthens in the post-COVID-19 period, particularly in countries of Africa and North America. By analysing countries in the highest uncertainty regions the study contributes to the international macroeconomics literature by providing new evidence on how global uncertainty shocks reshape macroeconomic dynamics across regions with heterogeneous economic structures, offering important implications for macroeconomic stabilisation in an increasingly uncertain global landscape.

    Economic and environmental factors influencing beef production in high-income countries: Panel evidence
    (Elsevier B.V., 2026-05-06) Susan, H; Mendis, K; Perera, N; Silva, Y; Jayathilaka, R
    As the global population grows, dietary patterns are shifting towards protein-rich foods, with beef production playing a critical role in balancing food security, economic growth, and environmental sustainability. Among income groups, high-income countries exhibit relatively stable, yet elevated levels of beef production compared to others, warranting focused investigation. This study evaluates the causal effects of beef consumption, greenhouse gas emissions, gross domestic product, and trade openness on beef production across 42 high-income countries from 1993 to 2022. A panel regression model with country-specific fixed effects is employed to control for unobserved heterogeneity, as supported by panel specification tests. Additionally, a simple moving average method is used to forecast short-term trends in beef production for 2023–2026. The findings reveal that there is no significant evidence to claim that there is an effect of beef consumption and gross domestic product on beef production. In contrast, trade openness negatively influences production, while greenhouse gas emissions exhibit a positive effect. Forecast results indicate increasing beef production in countries such as Uruguay, New Zealand, Ireland, Australia, Canada, and the United States. The study offers policy-relevant insights for governments and international organisations in aligning livestock production strategies with Sustainable Development Goals.

    Economic and Environmental Drivers of Carbon Emissions in Asia: Granger Causality Insights From Foreign Investment, Inflation, and Ecological Footprint
    (John Wiley and Sons Ltd, 2026) Nizar, S; Natkunarasa, A; Divyanjali, H; Jayathilaka, R
    Rising carbon emissions cause critical challenges to sustainable development, particularly in Asia which accounts for a substan-tial share of global emissions. The study investigates the short-run causal relationships between foreign direct investment, infla-tion, ecological footprint, and carbon emissions across 27 Asian countries (final analytical sample) over the period 2000–2023.Utilizing country-specific VAR-based Granger causality analysis, the study captures heterogeneous sustainability economic in-teractions without imposing uniform panel assumptions. The results reveal diverse unidirectional and bidirectional causalitypatterns, highlighting how macroeconomic pressures and environmental constraints jointly shape emission outcomes. Thesefindings underscore the importance of sustainable investment, energy price management, and institutional capacity in sup-porting sustainable communities and enhancing knowledge-driven sustainability transitions. From a managerial and policyperspective, the results provide actionable insights aligning with investment decisions, macroeconomic management, and envi-ronmental governance with the sustainable development goals, particularly SDG 13 (climate action), while recognizing country-specific development pathways.
