The Informal Economy: Unregistered Work and Hidden Economies

Core Idea

The informal economy comprises unregistered work and trade: street vending, domestic service, casual labor, small shops, family businesses. Informal workers are not registered, do not pay taxes, have no official employment protections or benefits. The informal economy is large: globally, roughly half of non-agricultural employment is informal; in poor countries, it is much larger. Informal work is often low-wage, insecure, and exploitative, yet it provides income for billions. The informality reflects both choices and constraints: some people prefer informal work's flexibility; most are in informal work because formal jobs are unavailable. Informal workers are vulnerable: they can be fired without recourse; they have no access to unemployment, healthcare, or pension; they are subject to arbitrary taxation and harassment from authorities. Yet informal economies are also dynamic: informal workers are entrepreneurs who create jobs and generate income; informal trade networks can be efficient. Understanding informal economy history requires recognizing that it is not simply a transitional phase that disappears with development — rather, it is a persistent feature of modern economies, particularly in poor countries. It also shows that development requires not just GDP growth but formalization: bringing informal workers into registered employment with protections and benefits.

Explainer

The concept of the informal economy is relatively new — Keith Hart coined the term in 1971 — but the underlying phenomena are as old as settled society. In ancient cities, peddlers, porters, prostitutes, and craftspeople worked outside any formal registration system. Medieval European cities had elaborate guild systems regulating certain crafts, but vast swaths of urban labor — domestic service, street vending, casual construction, seasonal harvest work — occurred outside formal structures. Industrial cities of the 19th century had enormous populations of unregistered workers: the London poor documented by Henry Mayhew in 1851 included hundreds of distinct types of street sellers, scavengers, and service providers entirely outside formal employment. This 'casual labor market' was not a transitional aberration but a structural feature: too many people, not enough formal jobs.

What Hart's concept added was analytical clarity and a policy shift. Before 1971, development economists assumed that urban migration would be absorbed into formal wage employment as industries expanded — the Lewis model of development, where surplus rural labor flows into modern sector jobs. Hart's Ghanaian research showed this wasn't happening: migrants were not unemployed or passively waiting; they were generating income through entrepreneurial informal activity. This reframing had implications: rather than treating informality as a failure of development (not enough factories), analysts could see it as a resource — entrepreneurial capacity that might be supported and formalized.

The informal economy's scale is staggering. The ILO estimates that 2 billion workers — more than 60% of the global workforce — are informally employed. In sub-Saharan Africa, 85% of employment is informal; in South Asia, 68%; in Latin America, 53%. Even in wealthy OECD countries, informal employment is significant: unregistered domestic workers, undocumented migrants, cash-in-hand tradespeople. The common features: no social insurance, no minimum wage protection, no ability to claim unemployment benefits, vulnerable to arbitrary dismissal, exposed to wage theft with limited legal recourse. Informal workers bear all employment risk individually.

Hernando de Soto's influential analysis focused on a different dimension: informal property. His 1986 book 'The Other Path' documented that Peruvian informal entrepreneurs were not simply poor — they had accumulated substantial assets (homes built over years, businesses operating from these homes) but these assets were legally invisible. Without formal property titles, they couldn't use their homes as loan collateral. De Soto's solution — mass property titling — became a global development policy prescription. Peru conducted large-scale titling programs in the 1990s-2000s. Results were mixed: some investment increased, but the credit revolution de Soto predicted didn't materialize because financial infrastructure was also missing and income was too low to service mortgages. Formalization requires not just legal recognition but financial systems capable of extending credit at reasonable rates.

The 21st century has produced a paradoxical development: informal employment expanding within wealthy economies through the 'gig economy.' Platform companies (Uber, DoorDash, TaskRabbit) reclassify employees as contractors, eliminating employment obligations. The algorithmic management of these workers — constant monitoring, dynamic pricing, rating-based discipline — achieves tight control while maintaining legal contractor status. California's AB5 (2019) sought to reclassify gig workers as employees; platforms spent $200 million on a ballot proposition (Prop 22) to exempt themselves. This struggle — over who counts as an employee and what protections work entails — is the contemporary version of the same battles fought in the 1830s-1930s over factory regulation, child labor, and minimum wages. The historical lesson: employment standards rarely extend automatically; they require organized political pressure against employers who benefit from unregulated labor.
