    Economic and trade determinants of carbon emissions in the American region
    (Elsevier, 2025-06) Methmini, D; Dharmapriya, N; Edirisinghe, S; Gunawardena, V; Jayathilaka, R; Wickramaarachchi, C; Dharmasena, T
    Balancing economic growth with sustainability has been a significant challenge over the past decades, largely due to the environmental damage caused by carbon emissions. This study investigates the relationship between energy consumption, gross domestic product (GDP), and trade openness and their impact on carbon emissions in 28 countries in the American region from 2000 to 2022. Using a multiple linear regression model for country-level analysis, the findings reveal diverse trends across the region. For instance, countries such as Antigua and Barbuda, Bolivia, Brazil, Chile, and Guatemala demonstrate a strong link between economic growth and increased carbon emissions. In contrast, developed nations such as the United States and Canada show signs of decoupling GDP growth from emissions, supporting the Environmental Kuznets Curve hypothesis, which suggests that higher income levels lead to reduced environmental degradation. The study highlights the importance of tailored, country-specific strategies to reduce emissions while promoting sustainable economic growth. A thorough understanding of the complex relationships between gross domestic product, energy consumption, trade openness, and carbon emissions will enable policymakers to devise strategies that balance ecological sustainability with socio-economic objectives.

    The cost of aging: Economic growth perspectives for Europe
    (PLOS ONE, 2023-06-23) Jayawardhana, T; Jayathilaka, R; Nimnadi, T; Anuththara, S; Karadanaarachchi, R; Galappathth, K; Dharmasena, T
    This study explores the causal relationship between the economy and the elderly population in 15 European countries. The economy was measured by the Per Capita Gross Domestic Product growth rate, while the population aged above 65 as a percentage of the total was considered the elderly population. The data were obtained from a time series dataset published by the World Bank for six decades from 1961 to 2021. The Granger causality test was employed in the study to analyse the impact between the economy and the elderly population. An alternate approach, wavelet coherence, was used to demonstrate the changes to the relationship between the two variables in Europe over the 60 years. The findings from the Granger causality test indicate a unidirectional Granger causality from the economy to the elderly population for Luxembourg, Austria, Denmark, Spain, and Sweden, while vice versa for Greece and the United Kingdom. Furthermore, for Belgium, Finland, France, Italy, Netherlands, Norway, Portugal, and Turkey, Granger causality does not exist between the said variables. Moreover, wavelet coherence analysis depicts that for Europe, the elderly population negatively affected the economic growth in the 1960s, and vice versa in the 1980s.

    Exploring the growth direction: the impact of exchange rate and purchasing managers index on economic growth in Sri Lanka
    (Springer Science and Business Media B.V., 2022-06-26) Jayathilaka, R; Rathnayake, R; Jayathilake, B; Dharmasena, T; Bodinayake, D; Kathriarachchi, D
    Numerous studies have been conducted, globally and locally, on the impact of the exchange rate on economic growth. In the local context, only a handful of research have investigated this area of study to determine the extent to which the Purchasing Managers’ Index infuence economic growth with the exchange rate, with limited research have been performed in Sri Lanka. This study explores the impact of exchange rate and Purchasing Managers’ Index on economic growth. Consequently, adopting an applied research methodology, the present study was based on secondary data published quarterly by the Central Bank of Sri Lanka reports and the Department of Census and Statistics of Sri Lanka from 2015 to 2021. The Vector autoregression model and Granger Causality Wald test were performed in this study. The empirical fndings highlighted that economic growth and Purchasing Managers’ Index have a signifcant negative impact on the economic growth, while the exchange rate had a signifcant positive impact on the economic growth. Furthermore, the exchange rate and the Purchasing Managers’ Index did not help to predict the exchange rate. The implications of the study demonstrate the relevance of the exchange rate and manufacturing Purchasing Managers’ Index as indicators of changes in overall economic growth activities at the macro level. The fndings will assist the Sri Lankan Government, policymakers, and foreign investors for efective decision making.

    The usage of cash deposit machines: An empirical analysis of identifying determinant factors
    (2020) Jayathilaka, R; Pathiratne, H; Jayanath, C; Perera, H; Wickremasinghe, S; Dharmasena, T
    Banks in Sri Lanka have launched a new generation of machines facilitating cash deposits that are credited instantly to accounts. The purpose of this paper is to identify the factors that influence the customers’ level of cash deposit machines (CDMs) usage. The Technology Acceptance Model (TAM) was used to accomplish the purpose of the research. The study used primary data in the form of a structured questionnaire covering the variables of TAM. Correlational analysis was used to demonstrate the constructed hypotheses among the variables, and multiple linear regression was used to measure the impact of customer attitude towards the usage of CDM. Results from the analysis indicated that reliability, perceived ease of use, perceived risk and perceived usefulness were significant factors, whereas the security factor was considered less significant concerning the use of CDMs. The contribution of this research is related to the analysis from a theoretical and empirical perspective of the customer attitude towards the usage of CDM. The practical implications drawn from this study will be useful to bank managers, marketing experts and advertising executives in providing good quality services promoting CDM, whilst developing grievance settlement to build trust among customers, enabling extensive usage.

    Driving Towards A ‘Low Carbon’ Economy Through Green Intrepreneurship In The Corporate Sector Of Sri Lanka
    (Sri Lanka Economic Association (SLEA), 2020-06) Dharmasena, T; Jayathilaka, R; Premerathna, H
    The ideologies and functionalities of green intrapreneurship in Sri Lanka, and contribution of such practices on corporate sustainability efforts are explored in the study by reviewing public limited companies. The set hypotheses are tested primarily through structural equation modeling, and the sustainability report score model is used to identify and measure the level of sustainability of the selected companies. The model fit is verified by the results, and in the process validated the hypotheses. The suggested model is proven through statistical parameters, and the results indicated a strong relationship between green culture and corporate sustainability. The overall consciousness on sustainability among public limited companies is lower moderate, and there is an identifiable gap between the understanding of top management about the concept of green intrapreneurship and the commitment for such practices within the organisations. This paper will contribute key knowledge base in the use of green intrapreneurship as a sustainable tool for the top management who are the decision makers in the public as well as corporate entities in Sri Lanka, and caters to the growing interest in a ‘low carbon’ economy.

    The impact of online reviews on inbound travellers’ decision making
    (Springer Nature, 2020-01-29) Jayathilaka, R; Dharmasena, T; Rezahi, N; Haththotuwegama, S
    This paper explores the hotel experience of inbound travellers to five-star boutique hotels of Sri Lanka and ascertains how hotels have satisfied their customers’ expectations through assessment of the positive and negative reviews. A qualitative research method of content analysis incorporating quantitative elements is engaged for this study. Data comes from a survey conducted by the TripAdvisor website. This study reveals that all dimensions of service quality played an equally important role from the perspective of customers. However, consumers are not satisfied due to the presence of perceived quality gaps. It was revealed that to maximise customer satisfaction, boutique hotels need to refer to online reviews to obtain authentic information from their guests. Sri Lanka is making strong efforts to support its tourism industry which got affected by the 2019 Sri Lanka Easter bombings, therefore the findings of this paper will undoubtedly be useful for the trade.

    The nexus between information and consumer confusion: Information provider vs information recipient
    (2020-03-31) Dharmasena, T; Jayathilaka, R
    Purpose – The purpose of this study is aimed at analysing the contributors of consumer confusion from theperspectiveofbothinformationprovidersandrecipients. Design/methodology/approach – Using Sri Lanka as a case study, this study demonstrates views of consumer confusion in terms of information and its contributors in light of the framework adopted by Lu andGursoy(2015). Findings – The results ascertain that too much, too similar and too ambiguous information from information providers’ perspective have a significant impact on consumer confusion in the context of the inbound tourist industryin Sri Lanka. Most importantly, it is evident that the information recipients’ knowledge and behaviour attributes, namely, internet experience, learning orientation, tolerance for ambiguity, price consciousness and requirement for cognition have no significant impact on consumer confusion. Furthermore, the quality andquantityofinformationprovidedarecrucialfortheminimisationoravoidanceofconsumerconfusion. Practical implications – The practical implications drawn from this study could influence all stakeholders of the inbound online tourism trade including managers, advertising executives and marketingexpertsinprovidinggoodqualityinformationtopromotetourism. Originality/value – The contribution of this research is related to the analysis from a theoretical and an empiricalperspectiveofboththeinformationproviders’ anddecision-makingofrecipients.
