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....

Prof. Gorton and Prof. Metrick of the Yale School of Management review 16 scholarly studies and papers on the causes of the 2008-2009 global financial crisis in the current isue of the Journal of Economic Literature. Another article in the same journal reviews 21 books on the subject. Samuelson says the most cited causes- lax regulation and passive regulators, and the policy of home ownership that encourage the packaging and of securitization of mortgages to government sponsored agencies Fannie Mae and Freddie Mac- are only the surface causes. If we are to explain how a whole society seemed to believe in the idea that somehow there was a way to maintain a rising tide continuously, with only small corrections over several decades, by the clever manipulation of monetary and fiscal policies; then one has to look to the hubris of economists who acted as if this was possible and the gullibility of business and a public that desperately wanted to believe as some have put it "that this time it was different," or that shrewd management of economic policy could actually bring about such a panacea. The abiding lesson is economic policies based on a better understanding of how modern industrial economies work are merely useful tools, no more no less, and there is no substitute for a good ethic, wise management and careful thinking on the part of the public, business and government, particularly for the people in leadership positions. ...

U.S. Federal Reserve governor Daniel Tarullo tells the Council on Foreign Relations that so much remains to be done four years after the financial crisis. The law firm of Davis Polk says 67 percent of deadlines were missed for new rules required to be set in place by the Dodd-Frank legislation, including the Volcker Rule. Tarullo said: "It is sobering to recognize that more than four years after the failure of Bear Stearns began the acute phase of the financial crisis, so much remains to be done." Tarullo fears that crucial momentum may be lost because of the long delays stemming from resistance by the banks. Tarullo met with bank CEO's in April 2012. Banks have protested that Fed stress tests have not revealed the parameters for the testing. Tarullo's response given at a recent Fed conference in Chicago were that this would let banks game the exercize by running the Federal Reserve model and not improving risk management and capital planning, making this a mechanical compliance exercize. Banks have particularly opposed a requirement that limits the risk in business between two banks to 10% of their credit risk....
