In recent years, particularly post 1990 and contrary to the expectation and predictions of many economists, there is ample evidence that the informal economy has expanded globally (Schneider et al., 2010). This, in addition to finding out the potential of the informal economy, has sparked renewed interest amongst researchers. Until now, however, most of the ‘empirical’ studies have concentrated on the Asian and Latin American countries (Debrah 2007), and most methodological approaches for studying the concept have remained debatable (Aryeetey, 2010). This thesis seeks to close a gap in the literature by developing two novel research frameworks: the Individual, Firm and State (IFS), and Four Circles (4Cs) to explain the link between theories and methods, as well as the impacts and benefits, of the informal economy. The study also utilises secondary and collected-primary data, modified-MIMIC and Currency approaches, to explore the determinants, characteristics, and regional prevalence of the Nigerian informal economy, as well as the relationships between the Nigerian informal economy and key macroeconomic variables/business enterprises. The results of the study demonstrate that the Nigerian informal economy has 65.4% participation rate, contributes an equivalent of 52-53% of official GDP, and provides cheap and easily accessible goods/services to members of the public, income generation for the government, and job, income and poverty reduction for informal participants. However, participants in the sector are confronted with many challenges: inadequate finances, inconsistent government policies, unfriendly business environment, and inadequate infrastructures. Similarly, the main determinants of the Nigerian informal economy are population growth, corruption, unemployment, and survival factors. Also, the study reports significant regional differences in participants’ income and education levels. Finally, the study finds the informal economy more prevalent in the north-west and south-west regions of Nigeria. Recommendations are proposed on the basis of the IFS; individuals and firms operating in the informal economy are encouraged to build up skills and become membership of relevant-trade unions. The government should implement policies which facilitate the creation of jobs, friendly business environment, entrepreneurial development, financial and training support for participants in the informal economy.
