A panel study applying the Chudik and Pesaran (2013) Panel Autoregressive Distributed Lag (P-ARDL) model to annual data spanning 1970–2023 across SADC countries. The analysis finds a long-run impact of FDI on economic growth, with FDI and GDP per capita exerting strong positive effects and human capital a negative effect, and recommends that SADC policymakers prioritise FDI attraction, human capital reform, job creation, infrastructure development, and institutional strengthening.

An analysis of religion's role as an economic institution in Sub-Saharan Africa, examining its impact on development and policy.

A study using a Panel Autoregressive Distributed Lag (P-ARDL) model to examine FDI's impact on growth in Sub-Saharan Africa, highlighting the substantial long-run effects of foreign investment, human capital, and GDP per capita.

Digital tax reforms that increase reporting frequency alter not only the reporting frequency of taxpayers but also the behavioural conditions that produce compliance information. This paper introduces behavioural reporting noise (BRN), defined as systematic distortions of reported compliance signals generated by adaptation to a reporting regime rather than underlying noncompliance.

This paper examines how Nigeria's fragmented digital identification architecture (NIN, BVN, SIM registries) affects administrative reach and state capacity. It finds that parallel registries produce systematic verification inconsistencies, raise transaction costs, constrain financial inclusion, and generate enforcement gaps.

Tax Orientation Statement (RTOS) as an early guidance intervention within HM Revenue and Customs’ (HMRC) Government Gateway digital services. It identifies a recurring compliance pattern in which some individuals entering the UK tax system through Pay-As-You-Earn (PAYE) employment treat employer withholding as if it settles their full tax obligations. As a result, overseas income, including rental receipts, business profit distributions, foreign investment returns, and overseas pension income, may remain undeclared for several tax years. In some cases, HMRC detects such non-compliance only after a substantial delay, by which point retrospective assessment, interest charges, and penalties may be difficult to avoid.The proposed RTOS would address this information gap through a brief yes-or-no orientation check presented at an early administrative touchpoint, directing users to relevant guidance without creating tax liability, requiring asset disclosure, or triggering enforcement action. Drawing on behavioural tax compliance theory, comparative tax administration, and published HMRC administrative data, the paper argues that a low-cost, well-timed intervention within existing digital infrastructure may help reduce delayed disclosure, improve taxpayer understanding of worldwide income obligations, and lower the volume of multi-year compliance investigations. More broadly, the paper shows how a preventative compliance approach may be incorporated into existing UK administrative arrangements

Capital flight remains a pervasive constraint on economic development in Nigeria, yet the dominant literature has concentrated on its determinants and magnitude rather than its internal structural consequences. This paper examines the developmental consequences of capital flight through an Economic Linkages Framework, an original conceptual architecture that synthesises Hirschman's (1958) backward and forward linkage theory, Keynesian multiplier analysis, and endogenous growth theory to explain how capital flight disrupts the processes through which domestic investment generates compounding economic value.The framework distinguishes two structural pathways. When capital is retained domestically, it initiates multiplier cascades through business expansion, supply chain deepening, employment generation, and fiscal strengthening, constituting positive economic linkages. When capital exits the economy, these pathways are severed, producing weakened aggregate demand, reduced productivity spillovers, labour market deterioration, and tax base erosion, constituting negative economic linkages and structural fragmentation. To operationalise these arguments, the paper introduces the Domestic Capital Circulation Curve (DCCC), a non-linear growth model grounded in Barro and Sala-iMartin's (1995) endogenous growth framework and Ramsey-Cass-Koopmans capital accumulation theory. A quadratic empirical specification is estimated using Nigerian time-series data (1991–2017) via OLS with heteroscedasticity-consistent standard errors. The model is explicitly framed as an empirical illustration of the theoretical framework rather than a fully identified causal test.The results suggest that labour market conditions may be an important transmission channel: a one percentage point increase in the unemployment rate is associated with a 2.48 percentage point reduction in GDP growth (p < 0.001), validating the labour market linkage mechanism. Capital flight coefficients are not individually significant but exhibit sign patterns consistent with the non-linear damage hypothesis. The model explains 57.4% of variance in GDP growth (R² = 0.574). The paper contributes to development economics by reframing capital flight as a problem of linkage disruption rather than simple financial outflow, providing a theoretically grounded and policy-relevant framework for Nigeria and comparable resourcedependent economies.
