- The McKinsey Global Institute's study of United States labor productivity growth from 1995 to 2000. Robert Solow, a Nobel laureate in economics and an adviser on the study, noted that the most important factor in the growth of productivity was Wal-Mart. And because the study measured productivity per man hour rather than per payroll dollar, low hourly wages cannot explain the increase.
- When Wal-Mart enters a market, prices decrease by 8 percent in rural areas and 5 percent in urban areas. With two-thirds of Wal-Mart stores in rural areas, this means that Wal-Mart saves its consumers something like $16 billion a year. And because Wal-Mart's presence forces the store's competitors to charge lower prices as well, this $16 billion figure understates the company's real impact by at least half.

- "Our research shows that Wal-Mart operates two-and-a-half times as much selling space per inhabitant in the poorest third of states as in the richest third. And within that poorest third of states, 80 percent of Wal-Mart's square footage is in the 25 percent of ZIP codes with the greatest number of poor households. Without the much-maligned Wal-Mart, the rural poor, in particular, would pay several percentage points more for the food and other merchandise that after housing is their largest household expense. sehold expense."
