Rostow's five stages of economic development model outlines the typical progression of economies: 1) Traditional society relies on agriculture. 2) Preconditions develop for take-off through increased productivity. 3) Take-off occurs when economies shift from agriculture to production. 4) A 60-year drive to maturity follows as economies reinvest profits. 5) The final stage is the age of mass consumption where economies can export goods. Business environments are impacted as economies progress through increasing opportunities for specialization and trade.
