Long Term Relationship in Export Equation

To assess on Exports dynamics the recent trend into the literature advocates the use in panel data modeling of dynamic panel data with an error correction mechanism. The main characteristic to this specification is to take into account at the same time the short and the long run dynamics. The short run dynamics have give inside into the literature on the examination of the substitution effect between exports and domestic sales. While the long run dynamics have give inside to the unitary elasticity assumption between exports and income. Nevertheless the long run dynamics is not rich even the adances in statistical techniques. In fact, due to data limitations this is some times restricted to an anlyze in time series modeling or in panel data this lack of consistence for an cointegration approach. Then the aim of this study to reassess this long run dynamics in a panel data framework using a cointegration approach. We lies ou assessment on the model of capacity constraints for the exports dynamics. We use data between 1974-2021 for CEMAC area. Following the obtained results the size of the coefficients is overall plausibe in the long term dynamics.
