Economic barriers are features of an economy that stop real GDP growing and living standards rising.

Five barriers inside the economy

BarrierHow it holds the economy back
Rising inequalityThe poor cannot afford school or health care; demand stays low
Poor infrastructure and technologyNo roads, power or internet: high costs, low output
Low human capitalWeak schooling and poor health: low productivity
A large informal economyUntaxed, unprotected work: little revenue, no loans
Geography, climate and diseaseLandlocked, droughts, malaria: high costs, lost work days

The points to remember

  • Name the barrier, then the link to growth: lower investment, productivity or demand.
  • Development questions need the link to health, education and income too.

2

Indebtedness
