The relationship between trade liberalization and product quality is both empirically and theoretically ambiguous. This paper empirically investigates the impact of tariff liberalization on product quality upgrading in the South African...

The preponderance and stringency of product standards have implications for global trade, especially for developing countries. Despite the importance of this issue to Africa, only a few empirical studies exist in the area. It is on this basis...

This paper investigates the effects of war on trade in the Middle East and North Africa region (MENA), an area at considerable risk for conflicts. Using an augmented gravity model, we introduce a war variable and distinguish between different...

Two nonexclusive hypotheses have been put forward to explain why exporters enjoy higher productivity than do non-exporters: self-selection and learning-by-exporting. In the case of a small economy such as Ghana’s, we suspect that self-...

This paper studies the impact of trade restrictions and illegal trade on price disparities within Nigeria, where a long list of import prohibitions on various consumer goods have raised the price of the consumption basket. Large-scale illegal...

There are differentials in the conclusion of scholars as to what undermines Africa’s export flows to the European Union (EU) and United State of America (USA). While the impact of tariffs has been reduced due to the unilateral preferential...

This paper quantifies the average effect of distance on bilateral agricultural trade using a large sample of countries. We focus on identifying time-varying effects of distance on trade to test whether the marginal effect has gradually diminished...

This paper uses the border effect estimate from a gravity model to analyze the level of market trade integration among Algeria, Egypt, Mauritania, Morocco, and Tunisia from 2005-2012. We analyze total trade as well as trade in agricultural and...

The objective of this paper is to analyze trade potential versus actual realized trade among North African trading partners. Following the literature on production economics, we built a stochastic frontier gravity model. The underlying assumption...
