This paper assesses the link between exchange volatility and exports in Egypt by combining wavelet analysis with an optimal GARCH model chosen among various extensions. The observed outcomes reveal that this relationship is complex and depends then widely to frequency-to-frequency variation and...

This paper analyses the relationship between exports, innovative activities and size and their effect over firms’ technical efficiency and then over their productivity. The analysis takes, also, into account other variables that could affect productivity as industrial sector, or firms’...

This study addresses the robustness of the connection between exchange rate uncertainty and Tunisia’s exports along several econometric methods, acknowledging the complexity of this relationship. To this end, we apply conventional methods (OLS by threshold, instrumental variable by threshold...

The core focus of this paper is to analyze the dynamic interactions between changes in exchange rate (nominal and real terms) and exports to GDP ratio in Russia. To this end, we apply a new approach based on a time varying dynamic coherence function, called, evolutionary co-spectral analysis....

The success of exports in Vietnam has become a driving force for economic growth since the reform in 1986. The paper uses data from 2001 to 2004 to estimates the gravity model for Vietnam’s exports with the random effect estimation. The empirical results show that the bilateral trade of...
