Publication Open Access 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, TThis 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.Publication Open Access 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, DNumerous 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.Publication Embargo Exploring the growth direction: the impact of exchange rate and purchasing managers index on economic growth in Sri Lanka(Springer, 2022-07-22) Jayathilaka, R; Rathnayake, R; Jayathilake, B; Dharmasena, T; Bodinayake, D; Kathriarachchi, DNumerous studies have been conducted, globally and locally, on the impact of the exchange rate on economic growth.
