Why is it that a decrease in the discount rate does not normally lead to an increase in borrowed reserves? use the supply and demand analysis of the market for reserves to explain?

Gif the federal reserve did not regulate fiscal policy, monitor banks and provide services for banks, what would most likely be the economic conditions to transact business in the u. s.? the economy would primarily be based on a barter system rather than a fiat system. there would be no discrimination in lending by local banks. the economy would be less efficient and transactions most likely more costly.
