U.S. monetary and fiscal policy since Great Depression to the present

In my bachelor's work I would like to focus on monetary and fiscal policy of the U.S. since the Great Depression to the present. My work will focus especially on three main topics. In the first part I will try to summarize the causes and consequences of the Great Depression, in another part I will pay attention to 1950s and 1960s in which the Keynesian theory prevailed. Finally I will try to find out if there are any common elements of the financial crisis in 1930s and of the current one. Seeing that I want to reveal the causes of the Great Depression, on which I will base my findings later, I will devote a few words to the characteristics of the golden era in the 1920s at the beginning of my work
