【專八mini系列】大蕭條（4/7）

Scholars have not agreed on the exact causes and their relative importance. The search for causes is closely connected to the question of how to avoid a future depression, and so the political and policy viewpoints of scholars are mixed into the analysis of historic events eight decades ago. The even larger question is whether it was largely a failure on the part of free markets or largely a failure on the part of government efforts to regulate interest rates, curtail widespread bank failures, and control the money supply. Those who believe in a large role for the state in the economy believe it was mostly a failure of the free markets and those who believe in free markets believe it was mostly a failure of government that compounded the problem. Current theories may be broadly classified into three main points of view. First 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.
