This is a festschrift for Pius Okigbo, a foremost economist, public intellectual and trailblazer of Nigeria's development in the immediate aftermath of colonial rule. The work is comprised of twelve chapters and organised into four sections: Memoirs and Tributes; Okigbo and the Evolution of the Nigerian State; Economic Policy and Public Finance in Nigeria and Africa; and Intellectuals, Public Leadership and Civil Society. Evaluating Okigbo's contribution to international and national economic theory, and drawing on his legacy, the papers address subjects such as: the evolution of the Nigerian State; the appropriate place of the State in economic development in Nigeria and on the African continent more widely; the role of civil society in economic planning and good governance; fiscal federalism; the principles of derivation; regional integration; and the probity and viability of public institutions.
