Salifou Issoufou, International Monetary Fund and Nama Ouattara, Université Paris-Sud 11

Applying the Arellano and Bond (year) dynamic generalized method of moments estimator to a panel of 46 African countries over the period of 1985 through 2007, we find that green investment lowers aggregate productivity growth.

To the best of our knowledge, this paper is the first to present aggregate evidence of the impacts of green investment on productivity.
