Exhibit 2 b Why the Aggregate Demand Curve Is Downward Sloping Interest Rate Effect Price level falls®purchasing power rises®less money needed to buy fixed bundle of goods®save more®supply of credit rises®interest rate falls®businesses and households borrow more at lower interest rate®buy more goods. Price level rises®purchasing power falls®borrow money in order to continue to buy fixed bundle of goods®demand for credit rises®interest rate rises®businesses and households borrow less at higher interest rate®buy fewer goods.
