Answer:
Harding - raised tariffs.
Coolidge - frugal policies.
Both - pro-business agenda, reduced world wide armament.
Explanation:
Warren Harding and Calvin Coolidge were the 29th and 30th Presidents of the United States. Both of their terms were during 1920's.
While their policies differentiated in some aspects, in other they were quite similar. For example, they were both republicans, who had a pro-business agenda.
But, living in the aftermath of World War I, Harding's main political goal was to protect american industries and agriculture to secure postwar recovery and avoid recession. Main strategy for this was to impose and raise tariffs. Coolidge continued with this policies (with keeping the tariffs high, but not raising them anymore), trying to protect american manufacturing against foreign competition. Harding's tariffs were at the record high by that time.
Also, they were both aiming to reduce world wide armament to prevent another disaster like the WWI. While Harding urged for lower defence costs during his campaign, this was not a major issue for him. He enacted an international agreement for reducing naval fleets of major powers at that time - USA, UK and Japan. On the other side, Calvin Coolidge's primary foreign policy initiative was the Kellog-Briand Pact of 1928, with the goal of renuncing war, as an instrument of national policy. Even though this Pact was never fully achieved, he managed to cut spending for the military, which leads us to his broader policies of cutting military spendings.
As oposed to Harding who was a protectionist, Calvin Coolidge believed in the minimal involvement of the state in order to produce government surplus, which is why he is known by his frugal policies.
