Loanable Funds Theory of Interest • Interest rate from supply and demand of funds available for lending, not total S+D for money • Supply (households): upsloping higher i more funds (“bribe” for giving up current consumption) • Demand (firms/gov’t): expected rate of return from investment in capital goods: downsloping bc fewer investments will have that level of return
