" Low confidence has caused credit markets to freeze up. Lenders do not trust that they will be paid back. Under the circumstances those who want to spend find it difficult to obtain the credit they need; those who supply the goods find it difficult to obtain the working capital they need. As a result the usual fiscal multipliers, from increased government expenditures or from decreased taxes, will be smaller—probably much smaller. "
