Natural Resources and Political Patronage in Africa: An Ethnicity Level Analysis
Review of Development Economics, Volume 30, Issue 3, Page 1957-1972, August 2026.ABSTRACT We investigate the effect of resource discoveries on ethnicity‐level political patronage in Africa using a large geospatial dataset of 254 ethnic groups in 15 countries over the period 1960–2004. We find that the first (or single first) resource discovery in a virgin ethnic homeland increases the share of cabinet posts of that ethnicity.

Strategic Management Journal, Volume 47, Issue 6, Page 1671-1729, June 2026.Abstract Research Summary We study how the entry of a rival platform affects the strategies of the incumbent's complementors. The latter face a trade‐off: While the entry threatens their benefits from indirect network effects, it also allows them to escape intense within‐platform competition.
