One of the primary policy issues over the years in the context of the Nigerian economy has been how to enhance the performance of the non-oil export sector of the economy in order to diversify the country's export base and contribute more to GDP (gross domestic product). Rather than a lack of policy initiatives, the noticeably abysmal performance of Nigerian non-oil exports has been increasingly attributed to poor policy implementation. However, the question of whether such poor implementation is due to the quality of institutional settings, particularly in a developing economy such as Nigeria, has been largely unexplored. To the best of our knowledge, none of the previous studies deemed it necessary to control for the role of institutional quality in the non-oil export-growth nexus from the perspective of the Nigerian economy. To bridge this important gap in the literature, we hypothesize that institutional qualities matter in the relationship between economic growth and non-oil exports. Motivated by a desire to diversify Nigeria's economy away from its reliance on oil exports, this study re-examines the export-led growth hypothesis from the standpoint of non-oil exports while accounting for the role of institutional qualities. We employ the ARDL estimation technique as the best econometric model for the study given its suitability for variables of mixed order of integration in terms of the series' stationarity. More so, the ARDL technique enables us to simultaneously capture both the short-run and long-run dynamics of the nexus. Empirically, we show results that suggest that improved institutional qualities have the potential to boost the positive effects of non-oil exports on economic growth. We also find that the extent to which institutional quality matters for enhancing the effects of non-oil exports on economic growth depends on the institutional quality indicators chosen. On the whole, we expand on the export-led growth hypothesis by considering the role of institutional characteristics and conclude that improving institutional qualities should be prioritized in the path to Nigerian economic diversification.

Workers' remittances represent up to 47 percent of gross domestic product in some Asian countries. Also, workers' remittances to the Asian region were estimated to reach $256 billion out of $483 billion received by developing countries. However, the growth effect of workers' remittance in Asia has, over the years, remained an open empirical question. To this end, this study examines the impact of workers' remittance and its interactive effects with financial development and institutional quality on economic growth. The study used a partial Gram-Schmidt orthogonalization procedure, which enable us to examine whether the marginal effect of workers' remittances depends on the degree of financial development and institutional quality. It also used a Pooled Mean Group (PMG) estimator on panel dataset for a period of 1984-2010 from fifteen (15) remittance-receiving Asian countries. The results of this study shows that, workers' remittance impacts positively on economic growth in remittance-receiving Asian countries. But, the growth effect is higher in Asian countries with improved financial development but relatively weak institutions. According to the findings a percentage point increase in per capita workers' remittance leads to a long-run increase in per capita income by 0.103 percentage points. Moreover, the marginal effect of workers' remittance on economic growth rises with increase in the degree of financial development. But it declines with improvement in institutional environment. The partial derivative of economic growth with respect to workers' remittance at the mean level of financial development is 9.733. Similarly, the derivative evaluated at the minimum and maximum levels of financial development are found to be 1.355, and 32.087 respectively. The proportions of these derivatives at different levels of financial development showed that the marginal growth effect of workers' remittances rises with increase in the degree of financial development in remittance-receiving Asian countries. However, the partial derivative of economic growth with respect to workers' remittance at the mean level of institutional quality is - 12.068. But, the partial derivative computed at the maximum and minimum levels of institutional quality take the value of -15.945 and - 6.785 respectively. This suggests that the better institutional environment is in a country the lesser will be the growth impact of workers' remittance. Overall, the result suggests that workers' remittance and financial development work as complements in enhancing economic growth. However, the former and institutional quality act as substitutes in promoting economic growth. [ABSTRACT FROM AUTHOR]
