In developing and transition economies as much as half the labor force works in the informal sector (or “shadow economy”). Informal firms congest infrastructure and other public services but do not contribute the taxes needed to finance them. Informal workers are unprotected against such negative shocks as ill-health, but for certain groups there can be scarce opportunities to enter the formal sector. Reducing informality requires better enforcement, more reasonable regulation, and economic growth.
