Research Deserts and Oases: Evidence from 27 Thousand Economics Journal Articles on Africa*
分析了非洲54个国家经济学研究分布极不均匀的原因，发现和平程度、政治制度、国际旅游、英语官方语言和人口能解释93%的跨国差异，且研究集中在高收入和大城市地区。
The distribution of economics research across Africa's 54 countries is highly uneven. I use a simple conceptual model and reduced‐form regressions with cross‐sectional, panel, and subnational data to explore the determinants of this distribution. Of the variation in research across countries, 93% can be explained by peacefulness, political institutions, international tourist arrivals, having English as an official language, and population. Within countries, research is concentrated in regions with higher income and large urban areas. Most research on African countries is context‐specific, so the lack of research in many countries and regions means a smaller potential evidence base for local policymakers.
