Côte d'Ivoire's economy is characterized by a significant informal sector that contributes to its Gross Domestic Product (GDP). Despite this, the nature and extent of the informal economy's role in GDP remain underexplored, particularly from a theoretical framework perspective. Theoretical frameworks will be constructed based on existing literature, economic models, and theoretical propositions from related disciplines such as economics, sociology, and management studies. No empirical data or statistical analysis is included in this article. The theoretical framework provides a robust structure for understanding the dynamics of the informal economy in Côte d'Ivoire and its implications for national economic policy and development strategies. Future research should empirically test the proposed hypotheses to validate the theoretical insights. Policy recommendations could include targeted interventions aimed at formalizing part of the informal sector while maintaining its benefits.
