In economics, stagflation is a situation in which the inflation rate is high and the economic growth rate slows down and unemployment remains steadily high. It raises a dilemma for economic policy since actions designed to lower inflation or reduce unemployment may actually worsen economic growth. The portmanteau stagflation is generally attributed to British politician Iain Macleod, who coined the phrase in his speech to Parliament in 1965.

The concept is notable because, in the version of Keynesian macroeconomic theory which was dominant between the end of WWII and the late-1970s, inflation and recession were regarded as mutually exclusive, the relationship between the two being described by the Phillips curve. Stagflation is also notable because it has generally proven to be difficult and, in human terms as well as budget deficits, very costly to eradicate once it starts.

In the political arena, one measure of stagflation, termed the Misery Index (derived by the simple addition of the inflation rate to the unemployment rate), was used to swing presidential elections in the United States in 1976 and 1980.

Dirk Müller (born 18 November 1975 in Burbach) is a German race driver, driving for BMW Team RLL in the 2012 American Le Mans Series. His former Schnitzer BMW team-mate Jörg Müller is unrelated, as is French driver Yvan Muller.

In 1996, Dirk Müller won a Formula 3 race at the Nürburgring. In 1998, after a win in the GT1 class of the 24 Hours of Daytona, he scored his first title, the German Porsche Cup, to be followed by the ALMS GT title in 2000.

From the 2002 to 2005 season, both Dirk and Jörg were driving BMW 3series model E46 touring cars for the Schnitzer-operated works squad Team Deutschland in the FIA European Touring Car Championship (now WTCC). Since 2006, the team uses the new BMW 3series model E90 which is based on the BMW 320si limited edition model that has a 4-cyl engine rather than the usual 6-cyl.

The 2004 24 Hours Nürburgring was won by both Müllers (and Hans-Joachim Stuck) with the BMW M3 GTR V8 that had been raced successfully in the 2001 ALMS. In 2005, the Müllers finished 2nd behind their sister car.

Milton Friedman (July 31, 1912 – November 16, 2006) was an American economist, statistician, and author who taught at the University of Chicago for more than three decades. He was a recipient of the Nobel Memorial Prize in Economic Sciences, and is known for his research on consumption analysis, monetary history and theory, and the complexity of stabilization policy. As a leader of the Chicago school of economics, he influenced the research agenda of the economics profession. A survey of economists ranked Friedman as the second most popular economist of the twentieth century behind John Maynard Keynes, and The Economist described him as "the most influential economist of the second half of the 20th century…possibly of all of it."

Friedman's challenges to what he later called "naive Keynesian" (as opposed to New Keynesian) theory began with his 1950s reinterpretation of the consumption function, and he became the main advocate opposing activist Keynesian government policies. In the late 1960s he described his own approach (along with all of mainstream economics) as using "Keynesian language and apparatus" yet rejecting its "initial" conclusions. During the 1960s he promoted an alternative macroeconomic policy known as "monetarism". He theorized there existed a "natural" rate of unemployment, and argued that governments could increase employment above this rate (e.g., by increasing aggregate demand) only at the risk of causing inflation to accelerate. He argued that the Phillips curve was not stable and predicted what would come to be known as stagflation. Friedman argued that, given the existence of the Federal Reserve, a constant small expansion of the money supply was the only wise policy.

Warren Edward Buffett (/ˈbʌfɨt/; born August 30, 1930) is an American business magnate, investor, and philanthropist. He is widely considered the most successful investor of the 20th century. He is the primary shareholder, chairman and CEO of Berkshire Hathaway. He is consistently ranked among the world's wealthiest people. He was ranked as the world's wealthiest person in 2008 and is the third wealthiest person in the world as of 2011. In 2012, American magazine Time named Buffett one of the most influential people in the world.

Buffett is called the "Wizard of Omaha", "Oracle of Omaha", or the "Sage of Omaha" and is noted for his adherence to the value investing philosophy and for his personal frugality despite his immense wealth. Buffett is also a notable philanthropist, having pledged to give away 99 percent of his fortune to philanthropic causes, primarily via the Gates Foundation. On April 11, 2012, he was diagnosed with prostate cancer.

Buffett was born in 1930 in Omaha, Nebraska, the second of three children and only son of U.S. Representative Howard Buffett, a fierce critic of the interventionist New Deal domestic and foreign policy, and his wife Leila (née Stahl). Buffett began his education at Rose Hill Elementary School in Omaha. In 1942, his father was elected to the first of four terms in the United States Congress, and after moving with his family to Washington, D.C., Warren finished elementary school, attended Alice Deal Junior High School, and graduated from Woodrow Wilson High School in 1947, where his senior yearbook picture reads: "likes math; a future stock broker."
