     Millions of Americans run to the bank or visit ATM when they need cash. They use credit cards when

they want to buy clothes, VCRs, or television sets. 　　

     But there is an underclass-people with low incomes and no credit history -who visit their neighborhood

pawnshops (当铺) when they need cash or a loan. 　　

     About 20 percent of the US population has no bank account. More than half of this group don't have credit

cards and cannot get bank loans. 　　

     "These people are borrowing an average of $50," said John P. Caskey of Swarthmore College in

Swarthmore, Pennsylvania."If you add up in terms of how much dollar value pawnshops provide, they don't

look very important. If you add up how much of the population they serve or the number of loans they make,

they are important." 　　

     Because they make loans, pawnshops are a type of bank, often calling themselves"the bank of the little

people." 　　

     Caskey and Swarthmore student Brian Zidmund in 1989 looked at the importance of pawnshops in the US

economy-the first serious study of the subject since the 1930s. 　　

     Their conclusion: pawnshops are the consumer's lender of last resort (最后贷款人). 　　

     Pawnshop customers typically cannot get credit at banks. They have poor credit records, low and unstable

incomes, or cannot maintain positive bank account balances. 　　

     Typically, pawnshop customers borrow relatively small amounts that traditional lenders are unwilling or

unable to provide on a secured basis. 　　

     "If you look at total consumer credit, the amounts provided by pawnshops remain small," Caskey said.

"They are lending mainly to low-income people. In terms of the population they serve, they're really important." 　　

     In 1988, there were about 6,900 pawnshops in the United States - one for every two commercial banks.

They made about 35 million loans, providing 1 percent of the nation's consumer credit.
