GOVERNMENT CAPITAL EXPENDITURE AND SOCIO-ECONOMIC DEVELOPMENT IN A POST-CONFLICT ECONOMY: EVIDENCE FROM BORNO STATE, NIGERIA

Abstract

This study examines the relationship between government capital expenditure and socio-economic development in Borno State, Nigeria, a region that has endured over a decade of devastating insurgency by the Boko Haram terrorist group. Using a mixed-methods research design that combines quantitative secondary data analysis with qualitative field-based evidence, the study covers the period 2010–2023, encompassing both peak-conflict and post-conflict reconstruction phases. Drawing on disaggregated state-level budgetary data obtained from the Borno State Ministry of Finance and Budget, the National Bureau of Statistics (NBS), and the Central Bank of Nigeria (CBN) Statistical Bulletins, the study evaluates the impact of capital spending across education, healthcare, infrastructure, agriculture, and security on selected socio-economic indicators including the Human Development Index (HDI), poverty headcount ratio, primary school enrolment rate, infant mortality rate, and per capita income. The theoretical framework integrates Wagner's Law of Increasing State Activity, the Keynesian public expenditure multiplier theory, and the Capability Approach advanced by Amartya Sen. Employing Autoregressive Distributed Lag (ARDL) bounds testing cointegration, Vector Error Correction Modelling (VECM), and fixed-effects panel regression, the empirical results reveal a statistically significant positive long-run relationship between capital expenditure and socio-economic development outcomes in Borno State (p < 0.01). Capital allocations to education (β = 0.41), health (β = 0.33), and infrastructure (β = 0.27) exert the strongest marginal effects on the composite Human Development Index. However, the findings also expose critical structural weaknesses: chronic capital expenditure underperformance (budget implementation rate averaging 43.2%), severe leakages attributable to corruption and institutional fragility, and a pronounced misalignment between capital budget priorities and the actual developmental needs of displaced and returning populations. The study concludes that post-conflict fiscal policy in Borno State must urgently pivot toward need-specific, spatially targeted, and accountability-anchored capital investments to catalyse genuine and sustainable socio-economic recovery. The research contributes novel empirical evidence to the limited literature on public finance in conflict-affected sub-national economies in Sub-Saharan Africa.
