a) The federal government had to expand the amount of currency in the economy, in order to do that, it had to buy federal bonds and deposit the bonds with the treasury, thus the bank capital was converted into cash to finance the war. In addition tax rates were increased and new paper currency was printed.
The government needed the money to fund the war, which is why this policy was undertaken, it was the easiest form of raising money by buying bonds which would have to be repaid after a long duration.
Policy changes were appropriate at that time as the government did not have any choice, it needed cash.
b) Higher tariffs kept foreign goods outside and industrial workers had much higher wages because of this. It was advocated that higher tariffs brought prosperity to the nation. Thus higher tariff kept foreign companies outside.
The government wanted to protect local jobs and not increase more discontent in the population, the policy changes were appropriate from the perspective of the employment situation and people getting enough pay and jobs during such crisis.
