Byiers and Lui (2013) in this volume (Chapter 8) examine the regional corridor approaches in delivering AfT. They argue that corridors, by providing a focused and targeted approach to addressing trade-related bottlenecks, can alleviate many of the challenges related to the effectiveness of AfT. However, they also point to practical constraints, such as the need for specific financial mechanisms to establish and operate joint programmes at borders (Table 6.2). However, Karingi and Fabberoni (2011: 83) find very large disparities in AfT per capita in Africa as well as high volatility. More importantly, the fact that supply may be aligned with demand globally does not mean that the most critical projects are in fact being implemented at the national level and attention to this may neglect the fact that high-demand countries are frequently not those capable of absorbing large amounts of assistance.
