Publication Open Access Foreign direct investment and foreign reserves linkage: a global study based on wavelet coherence and granger causality(Springer Nature, 2025-04-02) Jayathilaka, R; Vidyapathirana, G; Fernando, C; Sandaruwan, C; Lakshani, SIn the contemporary global economy, foreign direct investment (FDI) and foreign reserves (FR) play a crucial role in economic stability, particularly amid geopolitical and financial uncertainties. This study examines the relationship between FR and FDI over a 23-year period (2002–2022), utilising panel data from 110 countries. By employing Wavelet Coherence analysis, the findings indicate that FR significantly influences FDI inflows across most regions, except in Europe, where the relationship is more complex. Additionally, the Granger causality test confirms a predominantly unidirectional linkage from FDI to FR in most countries, particularly in North America, Asia, and Oceania. These findings suggest that policies fostering economic stability, such as flexible tax regimes and strong governance, are essential for enhancing FDI attractiveness, particularly in regions where the FR-FDI relationship remains weak.Publication Open Access Tourism and economic growth: A global study on Granger causality and wavelet coherence(PLoS ONE, 2022-09-12) Wijesekara, C; Tittagalla, C; Jayathilaka, A; Ilukpotha, U; Jayathilaka, R; Jayasinghe, PThis paper empirically investigates the relationship between tourism and economic growth by using a panel data cointegration test, Granger causality test and Wavelet coherence analysis at the global level. This analysis examines 105 nations utilising panel data from 2003 to 2020. The findings indicates that in most regions, tourism contributes significantly to economic growth and vice versa. Developing trade across most of the regions appears to be a major influencer in the study, as a bidirectional association exists between trade openness and economic growth. Additionally, all regions other than the American region showed a one-way association between gross capital formation and economic growth. Therefore, it is crucial to highlight that using initiatives to increase demand would advance tourism while also boosting the economy.Publication Open Access Tourism and economic growth: A global study on Granger causality and wavelet coherence(researchgate.net, 2022-09-12) Wijesekara, C; Tittagalla, C; Ilukpotha, U; Jayathilaka, A; Jayathilaka, R; Jayasinghe, PThis paper empirically investigates the relationship between tourism and economic growth by using a panel data cointegration test, Granger causality test and Wavelet coherence analysis at the global level.
