This paper aims to discuss the theory of productivity growth and its empirical applications, several authors emphasize the impact of real exchange rate devaluation on productivity. The main research question is: does the real exchange rate have a positive or negative impact on productivity...

This paper, empirically, tests the validity of Okun’s law in Nigerian economy from 1980-2012. The two versions of the difference model approach of the Okun’s law are used even though one of them is frequently used in the literature. We utilize Var-cointegration method and examine the...

We analyze recent contributions to growth theory based on the model of expanding variety of Romer [Romer, P. (1990). “Endogenous technological change”. Journal of Political Economy 98, 71–102]. In the first part, we present different versions of the benchmark linear model with imperfect...

This paper deepens the analysis of the income elasticities of import and export demand in relation to the real exchange rate (RER) within a balance of payments constrained growth framework. It identifies how the RER can affect these elasticities and explores the resulting implications. A key...

Inflation, Faktorsubstitution und Wirtschaftswachstum Jüngere empirische Studien über den Zusammenhang zwischen Inflation und Wachstum zeigen, dass Inflation auch schon bei relativ geringen Raten negative Wachstumseffekte besitzen kann. In der monetären Wachstumstheorie fehlt es jedoch an...

This study empirically examined the interrelationship between the construction sector, oil prices, and the actual gross domestic product (GDP) in Nigeria. Using annual economic data from the National Bureau of Statistics (NBS), the OPEC Annual Statistical Bulletin, and econometric statistics, we...

The objective of this article is to present the structure and the first computational simulations of a two sector macrodynamic model that embed some elements of the post-keynesian theoretical framework. The theoretical elements embed in the model are: i) determination of the level of output by...
