Beginning in 2008 many nations of the world enacted fiscal stimulus plans in response to the Great Recession. These nations used different combinations of government spending and tax cuts to boost their sagging economies. Most of these plans were based on the Keynesian theory that deficit spending by governments can replace some of the demand lost during a recession and prevent the waste of economic resources idled by a lack of demand. The International Monetary Fund recommended that countries implement fiscal stimulus measures equal to 2% of their GDP to help offset the global contraction. In subsequent years, fiscal consolidation measures were implemented by some countries in an effort to reduce debt and deficit levels while at the same time stimulating economic recovery.
In 2008 the United States Congress passed—and then-President George W. Bush signed—the Economic Stimulus Act of 2008, a $152 billion stimulus designed to help stave off a recession. The bill primarily consisted of $600 tax rebates to low and middle income Americans.
The United States combined many stimulus measures into the American Recovery and Reinvestment Act of 2009, a $787 billion bill covering a variety of expenditures from rebates on taxes to business investment. $184.9 billion was to be spent in 2009, and $399.4 billion was to be spent in 2010 with the remainder of the bill's appropriations spread over the rest of the decade. Announcements of rescue plans were associated with positive returns whereas a public intervention in favor of a specific bank showed negative impacts.
A statement on the government's website said the State Council had approved a plan to invest 4 trillion yuan in infrastructure and social welfare by the end of 2010. This stimulus, equivalent to US$586 billion, represented a pledge comparable to that subsequently announced by the United States, but which came from an economy only one third the size. The stimulus package will be invested in key areas such as housing, rural infrastructure, transportation, health and education, environment, industry, disaster rebuilding, income-building, tax cuts, and finance.
