Results of cointegration confirm that workers' remittances in Sri Lanka have both long-run and short-run beneficial relationship with human capital formation. The Granger causality test results indicate that there is a two-way causal relationship between workers' remittances and human capital formation. The results of forecast error variance decomposition expose that innovation of workers' remittances contributes to the forecast error variance in human capital in bell shape. Further, the empirical evidence of impulse response function analysis reveals that a positive standard deviation shock to workers' remittances has an immediate significant positive impact on human capital formation in Sri Lanka for a period of up to ten years.Practical implicationsThis research provides insights into the workers' remittances in human capital formation in Sri Lanka. The findings of this study provides evidence that workers' remittances help to produce human capital formation.Originality/valueBy using the ARDL Bounds cointegration and other techniques in Sri Lanka, this study fills an important gap in academic literature.

Global food price indices (GFPI) are collected from FAOSTAT website. Data for domestic prices (CPI and CFPI) are collected from CEIC website. Exchange rates for each country are collected from IMF website. The empirical statistical results are derived by using a battery of parametric and non-parametric econometric techniques using monthly data of price series for the study period, 2005M1 to 2017M12. The co-integration analysis results confirm that the global food prices and domestic prices are co-integrated. Granger–causality test reveals the unidirectional causal relationship running from global food prices to domestic prices over the study period for Pakistan and Sri Lanka. However, In the case of India, Bangladesh and Nepal, samples do not show the evidence of causal relationship in the short run. However, in the long run, GFPI Granger cause local prices i...

It is supported by academics and scholars that defense expenditure can significantly affect a country’s economic growth and in some cases it influences external and internal debt. However, relevant empirical studies have produced contradictory evidence while the literature in this field remains relatively poor. Since independence, Sri Lanka has taken several steps to build up its economy in a successful way. At the same time, the country suffered nearly three decades of civil war and heavier defense burden during this time. Military expenditure was very low before the 1980s, but since then a need for foreign borrowing and external debt accumulation grew. Therefore, there should be a possibility relation between the deficits and foreign borrowing in Sri Lanka.
