The IMF's changing views on the value of fiscal austerity. In the current debate about the value of fiscal austerity, there is the IMF view, a German view based on its own experience, and the views of other countries in Europe. The IMF's view has shifted over time. The IMF World Economic Outlook 2010, describes its view of the effects of austerity measures in the form of spending cuts and tax increases- "Fiscal consolidation typically has a contractionary effect on output. A fiscal consolidation equal to 1% of GDP typically reduces GDP by about 0.5% within 2 years and raises the unemployment rate by about 0.3% percentage points." Over the longer term there are benefits as the private sector is not crowded out in the search for captal funding by the excessive government borrowing. The IMF's economic models suggest that it would take 5 years before reaching the breakeven point when the benefits of austerity measures exceed the effects of austerity. The German view held by German central bankers is that the actions stimulate growth in the short term. Manfred Neumann, professor emeritus at the Institute for Economic Policy at the University of Bonn, says this is called the "German hypothesis" as it reflects the experience of Germany from austerity actions taken by Germany. Laurence Ball, professor of Economics at John Hopkins University, is critical of the "German hypothesis" and its application across Europe in different situations. Germany is a large exporting nation and exports helped counterbalance the effects of austerity measures. Within the eurozone with fixed exchange rates the exports of less competitive countries cannot be boosted through devaluing the currency to gain price competitiveness. The other problem is that with interest rates close to zero in the euro zone the central banks cannot cut rates aggressively to counteract the effects of spending cuts. The problem gets compounded when a number of countries are taking austerity measures at the same time accentuating the downturn....
