Case Studies

Lagos State's transformation of its Internally Generated Revenue (IGR) system stands as one of the most significant fiscal capacity achievements in sub-Saharan Africa. In the early 2000s, Lagos was heavily dependent on federal allocations — its own revenue base too narrow to fund the infrastructure and services demanded by a rapidly growing megacity. What followed was a systematic reconstruction of the state's fiscal architecture.

The Lagos Internal Revenue Service (LIRS) was restructured and professionalised. Tax administration was digitised, expanding the formal taxpayer base and reducing leakage. Enforcement was strengthened, and revenue collection was separated from political interference. By 2023, Lagos had grown its IGR to among the highest of any subnational government on the continent — financing infrastructure, health systems, and public services that federal transfers alone could not have sustained.

The case illustrates a core argument of the book: fiscal capacity is not primarily a revenue problem. It is an institutional design problem. Lagos did not become richer. It became more capable of converting existing economic activity into investable public resources.

The growth of Nigeria's digital payments ecosystem — from a largely cash-based economy to one of Africa's most active fintech markets — offers a study in what coordinated governance can achieve when institutional actors align around a shared execution architecture.

The Central Bank of Nigeria's policy interventions — including the cashless policy, BVN (Bank Verification Number) rollout, and licensing of payment service banks — created a framework within which private sector innovation could compound. The NIP (Nigeria Interbank Settlement System Instant Payment) platform enabled real-time transfers across institutions. Interoperability frameworks allowed new entrants to plug into existing infrastructure rather than rebuild it.

The result was not the product of a single brilliant policy but of a sustained regulatory architecture that enabled coordination at scale. When multiple actors — regulators, banks, fintechs, telcos, and merchants — could transact within a coherent system, volume compounded. Transaction values that were negligible in 2010 reached trillions of naira annually by the early 2020s.

The liberalisation of Nigeria's telecommunications sector following the return to civilian government in 1999 produced one of the fastest market expansions in African history. From fewer than half a million fixed-line subscribers to over 200 million active mobile connections within two decades — the scale of the transformation is difficult to overstate. But the case study in The Capacity State is not primarily about the market. It is about the institution that made the market possible.

The Nigerian Communications Commission (NCC) was restructured as an independent regulatory body with technical expertise, clear mandate, and relative insulation from short-term political pressure. Spectrum allocation was managed through competitive auctions. Licensing frameworks were designed to attract foreign investment while maintaining regulatory coherence. Consumer protection mechanisms and quality-of-service standards gave the market rules it could operate within.

The NCC case demonstrates that in complex technical sectors, administrative competence — not just privatisation — is what converts market opportunity into delivered outcomes. Sector liberalisation without capable regulation produces fragmentation, not expansion.

Among Nigerian cities, Lagos has emerged as a distinctive case of talent concentration — attracting skilled professionals, entrepreneurs, and creatives in volumes that exceed what formal policy has deliberately engineered. The city's ability to generate and retain human capital illuminates a broader argument in The Capacity State: that institutional performance is ultimately constrained by the depth and durability of the human systems that sustain it.

The Lagos tech ecosystem — encompassing start-ups, accelerators, venture-backed companies, and diaspora returnees — has become a node of continental significance. This concentration was not accidental. It reflects the compounding effects of infrastructure investment (broadband penetration, co-working spaces), regulatory openness (fintech licensing frameworks), and a critical mass of talent dense enough to generate its own gravitational pull.

The book uses this case to examine how human capital accumulation and institutional capacity interact. Where talent concentrates, execution systems deepen. Where institutions are weak, talent disperses — and institutional memory fails to survive political transitions or leadership change.
