Causes of the Great Depression
Second, there are the monetarists, who believe that the Great Depression started as an ordinary recession, but that significant policy mistakes by monetary authorities (especially the Federal Reserve) caused a shrinking of the money supply which greatly exacerbated the economic situation, causing a recession to descend into the Great Depression. Related to this explanation are those who point to debt deflation causing those who borrow to owe ever more in real terms.
Great Depression in the United Kingdom
The Great Depression in the United Kingdom, also known as the Great Slump, was a period of national economic downturn in the 1930s, which had its origins in the global Great Depression. It was Britain's largest and most profound economic depression of the 20th century. The Great Depression originated in the United States in late 1929 and quickly spread to the world. Britain had never experienced the boom that had characterized the U.S., Germany, Canada and Australia in the 1920s, so its effect appeared less severe. Britain's world trade fell by half (1929–33), the output of heavy industry fell by a third, employment profits plunged in nearly all sectors. At the depth in summer 1932, registered unemployed numbered 3.5 million, and many more had only part-time employment.
