This paper investigates the determinants of sustained accelerations in goods and services exports. Strong predictors of export takeoffs include domestic and structural indicators such as lower macroeconomic uncertainty, improved quality of institutions, a depreciated exchange rate, and agricultural reforms. Lower tariffs, participation in global value chains and diversification also contribute to initiating export accelerations. The paper also finds heterogeneity, with somewhat different triggers for Latin America and the Caribbean, as well as for goods and services. Finally, despite the lack of a robust effect on output, export surges tend to be associated with lower post-acceleration unemployment and income inequality.
We review the current state of the West African Economic and Monetary Union’s tax coordination framework, against the main objectives of the WAEMU Treaty of 1994: reduce distortions to intra-community trade, and mobilize domestic tax revenue. The process of tax coordination in WAEMU is one of the most advanced in the world—de jure at least—, but remains in many areas ineffective de facto. Nevertheless, the framework has, to some extent, succeeded in converging tax systems, particularly statutory tax rates, and may have contributed to improving revenue mobilisation. Important lessons can be drawn from the WAEMU experience, particularly in terms of whether coordination should take the form of harmonization through a top-down approach, or a softer approach of sharing best practice and limiting certain types of tax competition.
