My provocative blog is getting quite a few reactions that are also quite provocative. This is good. Just want to clarify that electricity, and access to it, is crucial for firms. Without electricity, there would be no industrial and service activities. But many of us (advisers,consultants, policymakers....not firms) tend to forget that skills and transports do matter a lot, and frequently more than electricity. Many firms do not invest in Tanzania because unit labor costs are relatively high (low labor productivity with relatively high nominal wages --see recent excellent paper by A. Geld and Vijay) and transport costs are excessive (the Dar es Salaam port is one the least efficient in the world and domestic transport is still a nightmare with poor infrastructure and many roadblacks. See recent Trademark studies for more evidence.
