Households demand bank deposits for the liquidity services such assets
provide. Higher-yielding assets usually are available to finance futu
re consumption. Nevertheless, the demand for bank liabilities enables
banks to finance investment. One might therefore expect more capital i
n an economy utilizing banks. We show that, when low-wealth households
cannot borrow, bank lending increases the capital stock and reduces e
quilibrium interest rates, while making the real equilibrium more sens
itive to shifts in the demand for inside money. When households can bo
rrow, however, bank lending is absorbed by low-wealth households and b
anks have few effects on the real equilibrium.
