This paper examines the differences between author generated keywords and automatically generated keywords in one area of scientific and technical literature. Using inverse frequency, keywords produced using both methods are examined using a maximum likelihood algorithm. By reducing the scope and size of the corpus of literature examined, this study more closely emulates the information gatheri...

This study investigates the determinants of trade balance in West African and Monetary Union (WAEMU) over period 1975–2017. We employ Mean Group (MG) estimator along with grouped mean version Dynamic OLS (DOLS) Fully Modified (FMOLS) to deal both endogeneity cross-country heterogeneity. The results reveal that is negatively related domestic foreign income whereas real effective exchange rate de...
