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....

Krugman points to some striking facts about China in 2011. Consumer spending in China is only 35% of GDP and has declined over the years. There are no signs of rebalancing the economy away from exports by increasing consumer spending. China's dependence on exports for trade surpluses is greater than ever. Beyond this there is another disturbing fact. With weak consumer spending and heavy investment spending at about half of GDP, Kugman raises the question where is all that increase in spending going? Real estate investment takes up about half of the increase in investment spending, as the share of GDP of real estate investment almost doubles compared to figures for 2000. Much of the rest of the increase Krugman attributes to firms selling to the construction industry. The speculative fever, the corruption at the local level, the shadow banking system which is not protected and unsupervised, the poor quality of statistics, suggest a bubble phenomena that may not be under control of policy makers, and risks damaging China economy and the world economy in 2012-2013. After all China's economic and financial planners and banks are no better than America's or Japan's, where asset bubbles burst causing serious damage....

After over two decades of focus on GDP growth targets, China under prime minister Li Keqiang is giving more emphasis to job growth and problems of air pollution, education, and quality of life indicators. Premier Keqiang tells a news conference in Beijing in March 2014 that China needs to create 10 million new jobs each year. More bond defaults can be expected as the financial system is being changed with new rules. Li says China will no longer be "preoccupied" with GDP growth targets. Li made the new priorities clear-"The GDP growth we want is one that brings real benefits to our people, helps raise the quality and efficiency of economic development and contributes to energy conservation and environmental protection."

The Economist points out that China's total debt of government, corporate and households has grown by about 100% of GDP since 2008. The 2009 crisis led to rapid increase in debt. It is now about 250% of GDP, according to the Economist. Slower growth of below 7% risks reducing China's ability to service this debt. About half of this debt is owed by state owned companies and property developers. China can use its sovereign reserves to continue supporting bank and state owned companies. Investor's are pricing bank shares to reflect about 10% of this debt as bad debt even though government estimates are much lower. The reserves provided China time to fix the banking system since 2008, yet the debt keeps growing and China has failed to take strong action in the last 6 years. Complacency is a problem, and the incentives for local governments to continue prior practices that increase debt continue. As Krugman and other experts have pointed out at some point the rules of finance will apply to China as they have for other countries that faced a debt crisis- Japan in the late 1980's, South Korea and other Aisan countries in 1997, and the U.S. in 2008. Even without a crisis through deft managemen and use of reserves China risks zombifying the economy as old loans are backed up by new loans, with the further risk of misallocation of capital or poor use of capital. This lowers productivity of capital and hurts development. With poor statistics such as the figure of 1% of debt being bad debt cited here, the problems of complacency can be magnified, as there is less reason for a strong response....

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. ...
