%0 Journal Article %T Technology Gap and the Role of National Innovation System in a Balance of Payments Constrained Growth Model: Empirical Evidence From Nigeria %A H¨¹seyin Ozdeser %A Irfan Civcir %A Yohanna Panshak %J SAGE Open %@ 2158-2440 %D 2019 %R 10.1177/2158244019828846 %X This study empirically seeks to connect more strongly the post-Keynesian macroeconomic idea anchored on the balance of payment (BOP) constraint with the evolutionary microeconomic idea related to the dynamics of technological gap in shaping export quality and long-run growth. It employs autoregressive distributed lag model to examine the validity of Thirlwall¡¯s ¡°Law¡± on the Nigerian economy from 1981 to 2017. The study found that new version of the model improves significantly in explaining long-run growth of the economy. Therefore, it recommends, among others, a cautious reduction of various components of imports especially final consumption, increasing the export share of commodities with high demand in the international market as well as increasing government spending on R&D to enhance export quality for a sustainable growth of the economy %K balance of payments constraint %K relative prices %K technological gap %K national innovation system %K economic growth %U https://journals.sagepub.com/doi/full/10.1177/2158244019828846
