Book excerpt: Delve into the complex landscape of the informal economy with the Routledge Handbook of the Informal Economy, a groundbreaking volume that transcends conventional economic analysis by contextualizing it within a broader regulatory and social framework. This comprehensive handbook offers cutting-edge categorical, thematic, and regional analyses of the informal, or shadow, economy. An esteemed international ensemble of contributors draws on diverse economic perspectives, exploring a spectrum of definitions and measures, including household, firm-level, and employment-based metrics, alongside perceptional and model-based estimates. Employing a variety of econometric and methodological approaches, the volume provides both regional and global estimates of the informal economy's extent. Beyond conventional boundaries, it unveils various facets of informality, from child labor, tax evasion, and self-employment to precarious and undeclared work. In-depth examinations of the determinants and consequences of informality enhance the volume's robust analysis. As a forward-looking compendium, the handbook also offers insights into the future trajectory of the informal economy as we journey further into the 21st century. This definitive and up-to-date reference work is indispensable for readers in labor economics, development economics, political economy, policy studies, and sociology, offering a nuanced understanding of the multifaceted dimensions and dynamics of the informal economy.
