In his Condliffe Lecture, Professor Hausman highlighted the benefits that Wal-Mart brings to the American economy. While social activists have criticised Wal-Mart, Professor Hausman shows us rather that Wal-Mart has been responsible for massive decreases in prices that have greatly benefited the poor. Not only do the poor benefit by enjoying lower prices at Wal-Mart, prices at other shopping outlets drop considerably when a Wal-Mart opens. He calculates that when a Wal-Mart opens in a community, poor families are made better off by an amount equivalent to a quarter of their food expenditure: a substantial amount for those on low incomes.
