The contribution of exports to GDP in MINT countries that improve substantially just after their implantation of export promotion strategy in the late 1980s raises the issue of whether the growth in these countries is led by export or not. While a good number of studies have been found investigating whether economic growth is promoted by exports for developing countries having an outstanding share of export in GDP, no study investigating the export-led growth hypothesis for MINT countries has been found until recent times. The main purpose of this study is to fill up the void. The study employs panel cointegration technique with an aim to examine whether the export is the key factor of economic growth for MINT countries employing yearly secondary data that covers the period. Results of the study imply that economic growth of these countries is considerably exports driven. Moreover, there is an indication of improvement of efficiency as exports work along with the rise capital formation. As the employment opportunity of an economy is expanded through capital formation, the emerging MINT countries endowed with large population and favorable demographics are expected to become the major exporters with strong GDP growth by being able to attract adequate foreign investment.

The objective of this paper is to test the validity of the Export-led Growth Hypothesis (ELGH) in the Malaysian economy. Malaysia has always been considered to have attained its growth primarily through exports (Okposin, Bassey, Hamid, Halim, and Boon, 1999; Mun, 2008; Mahathir, 1990). In the past, several studies on this topic have been conducted but their analyses were limited to relationships using Bound-testing, Autoregressive –Distributed Lag (ARDL) and the Toda Yamamoto analysis. Empirical data and analysis in our paper cover a 21 – year span and quarterly time-series data (1991:Q1 – 2012:Q4) are used to test this ELG hypothesis. Also, many dynamic econometric measures including the Augmented Dickey Fuller (ADF) and Phillip – Perron (PP) unit root tests, Cointegration test as well as the Vector Error Correction model (VEC) for the long run have been applied. Based on these generic models, both real exports and capital stock (productivity) are found to have stimulated positive adjustments to economic growth in the long run whereas real exchange rate is found to have influenced economic growth negatively. Overall, our conclusion is that the ELG hypothesis seems applicable to Malaysia in the long run.

Using panel techniques, this paper estimates the causality among economic growth, exports, and Foreign Direct Investment (FDI) inflows for developing countries over the period of 1980 to 2008. The study indicates that; firstly, there is strong evidence of bidirectional causality between economic growth and FDI inflows. Secondly, the exports-led growth hypothesis is supported by the finding of unidirectional causality running from exports to economic growth in both the short-run and the long-run. Thirdly, export is not Granger caused by economic growth and FDI inflow in either the short run or the long run. On the basis of the obtained results, it is recommended that outward-oriented strategies and policies of attracting FDI be pursued by developing countries to achieve higher rates of economic growth. On the other hand, the countries can increase FDI inflows by stimulating their economic growth.

This study was an inquiry into the nexus of the foreign-direct investment (FDI) led growth hypothesis, and how it translates into the development of the Nigerian economy as of 1970 – 2018. The study utilized secondary data from the ‘World Development Indicators’ which were analysed using the Bounds test for cointegration and the ‘autoregressive distributed lag (ARDL) approach to divulge both the short-term cum the long-term influence of foreign direct investment net inflow on ‘economic development’ of Nigeria. The Bounds test was conducted after the unit root test revealed that the variables were stationary at mixed order of level and first difference. The outcome of the ARDL Bounds test supported confirmation of long-term association among the variables. The ARDL short-run error correction showed that 14.62% of the instability in the model was corrected yearly. In the short-term, it was discovered that FDI wielded a deleterious and substantial weight on ‘economic development of Nigeria. Meanwhile, the long-term estimates indicated that FDI influenced economic development positively, though not in a significant manner. The Granger causality test supported the fact that FDI causes ‘economic development’ in Nigeria. Given this potential of FDI exerting a positive effect on ‘economic development’, the paper recommended that bottlenecks inherent in FDI influxes in the country should be removed so as to reap the fullest benefits of such inflows in Nigeria.

The export-led growth hypothesis states a positive relationship between the growth of exports and long-run economic growth. This study examines the validity of the export-led growth hypothesis of services exports in 5 emerging economies, including Brazil, India, Nigeria, China, and South Africa (BINCS), for the period of 1980-2019. The study employs the panel mean group autoregressive distributed lag (ARDL) procedure to identify a causal relationship between services exports and gross domestic product (GDP) per capita. The findings show that the export-led growth hypothesis in services only has a positive effect on economic growth in the short run while other variables, including foreign direct investment (FDI), gross capital formation, and labour, increase economic growth in the long run. Hence, the emerging countries should focus more on internal investment to boost growth in the long and short run.
