摘要：The main aim of this paper is to investigate whether Wagner’s law holds in African countries. The authors use panel data for 30 African countries for the period from 1990 to 2005. The models used in this paper include the pooled ordinary least square (OLS), fixed effect model (FE) the random effect model (RE). Based on the results of the models, the study confirms that there is a strong support for Wagner’s law in African countries under investigation. This finding was robust to different estimation techniques used.
