Active learning ideas

The Informal Economy

Active learning helps students grasp the informal economy because it requires them to engage with real-world complexities that static texts cannot convey. By mapping, simulating, and comparing cases, students move beyond abstract definitions to see how geography, policy, and human decisions shape informal work every day.

Map Analysis: Geographic Distribution of Informal Activity

Pairs analyze maps or data visualizations showing the distribution of informal employment across US metropolitan areas or across regions of a developing country. They identify geographic patterns -- proximity to borders, urban density, industrial sector concentrations -- and develop hypotheses about why informality clusters in specific locations.

Explain the geographic factors that contribute to the growth of the informal economy.

Facilitation Tip

For the Map Analysis, have students annotate their maps with at least three specific geographic features (e.g., ports, transit hubs, zoning boundaries) that explain the distribution of informal vendors.

What to look for

Pose the question: 'Imagine you are a city planner. What are the top two geographic factors you would consider when deciding where to focus resources for supporting or regulating informal markets?' Have students share their reasoning, referencing specific urban contexts.

Stakeholder Simulation: Formalizing Street Vendors

Students take roles as street vendors, city licensing officials, formal business owners, and community health advocates in a simulation of a city council hearing on street vending regulation. Each group presents their interests and evidence, then the class negotiates a policy framework that acknowledges the tradeoffs involved.

Analyze the social and economic implications of informal labor for urban populations.

Facilitation Tip

During the Stakeholder Simulation, assign each student a role with a clear agenda and limited information to force negotiation and compromise.

What to look for

Provide students with a short case study of a city with a significant informal sector (e.g., a port city with informal shipping services). Ask them to identify two specific informal economic activities and explain one geographic reason for their prevalence and one social implication for residents.

Activity 03

• 50 min · Small Groups

Case Study Comparison: Informal Economy in Three Cities

Small groups each research informal economic activity in one city (Lagos, Mumbai, and a US city like Los Angeles or Houston). They profile the main sectors, geographic concentrations, and policy approaches in their city, then compare across cases to identify what is universal and what is context-specific about informal economic geography.

Evaluate policy approaches to integrate informal economic activities into the formal sector.

Facilitation Tip

In the Case Study Comparison, assign each group one city first, then require them to present a single slide linking their findings to a shared class framework of formalization costs and benefits.

What to look for

On an index card, ask students to write one policy idea to help informal workers transition to the formal economy. They should briefly explain why this policy might be effective, considering geographic or social barriers.

Activity 04

• Think-Pair-Share
• 25 min · Pairs

Think-Pair-Share: Costs and Benefits of Informality

Present three worker profiles: a day laborer in construction, an undocumented restaurant worker, and a freelance technology contractor. Students individually identify the costs (no legal protections, income instability) and benefits (flexibility, lower barriers to entry) of informality for each worker, then compare assessments with a partner before whole-class discussion.

Explain the geographic factors that contribute to the growth of the informal economy.

Facilitation Tip

In the Think-Pair-Share, provide sentence stems like 'One cost of informality is…' to guide precise academic language.

What to look for

Pose the question: 'Imagine you are a city planner. What are the top two geographic factors you would consider when deciding where to focus resources for supporting or regulating informal markets?' Have students share their reasoning, referencing specific urban contexts.

A few notes on teaching this unit

Experienced teachers approach this topic by starting with students’ own experiences of informal work—babysitting, tutoring, gig apps—before expanding to global cases. Avoid framing the informal economy solely as a problem; instead, highlight how it provides critical safety nets and economic opportunities that formal systems often miss. Research shows that students grasp tradeoffs better when they simulate real stakeholder conflicts rather than debate abstract pros and cons.

Successful learning looks like students using geographic and economic reasoning to explain where informal activity occurs, why it persists, and what tradeoffs arise when policies try to formalize it. They should connect their analysis to specific places, stakeholders, and data rather than making generalizations.

Watch Out for These Misconceptions

• During the Map Analysis activity, watch for students who shade entire continents as 'informal' without showing subnational variation.

  Use the Map Analysis to redirect students to fine-grained data like county-level IRS estimates of unreported income in US construction, or city-level port congestion data in Lima, to show that informality clusters in specific places rather than blankets entire regions.

• During the Stakeholder Simulation activity, listen for students who describe informal workers as uniformly exploited or uniformly successful.

  During the simulation, pause after the first round to ask each group to identify one type of informal worker they represented who would benefit from formalization and one who might be worse off, using the roles’ specific constraints.

• During the Case Study Comparison activity, watch for students who assume formalization always improves outcomes for informal workers.

  After the Case Study Comparison, ask groups to create a two-column table listing one concrete benefit and one concrete cost of formalization for each city they studied, forcing them to confront tradeoffs directly.
