In economics, stagflation, a portmanteau of ''stagnation'' and ''inflation'', is a situation in which the inflation rate is high, the economic growth rate slows, and unemployment remains steadily high. It raises a dilemma for economic policy, since actions designed to lower inflation may exacerbate unemployment, and vice versa. The term is generally attributed to a British Conservative Party politician who became chancellor of the exchequer in 1970, Iain Macleod, who coined the phrase in his speech to Parliament in 1965.〔Online Etymology Dictionary. Douglas Harper, Historian. http://dictionary.reference.com/browse/stagflation (accessed 5 May 2007).〕〔British ''House of Commons' Official Report'' (also known as ''Hansard''), 17 November 1965, page 1,165.〕〔 Introduction, page 9.〕〔 page 464〕 〔Nelson and Nikolov also point out that the term 'stagflation' has sometimes been erroneously attributed to Paul Samuelson.〕 Keynes did not use the term, but some of his work refers to the conditions that most would recognise as stagflation. In the version of Keynesian macroeconomic theory that was dominant between the end of World War II 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 very costly and difficult to eradicate once it starts, both in social terms and in budget deficits. One economic indicator, the misery index, is derived by the simple addition of the inflation rate to the unemployment rate. ==The Great Inflation== The term "stagflation" was first coined 〔"On 7 July 1970 again in the UK Parliament Macleod also used the term stagflation referring to the UK economy. The media began to use it, for example in ''The Economist'' (15 August 1970). Paul Samuelson used stagflation first in his Newsweek (19 March 1973) entitled ‘What’s Wrong?’. See Nelson and Nikolov (2002).〕 during a period of inflation and unemployment in the United Kingdom. The United Kingdom experienced an outbreak of inflation in the 1960s and 1970s. As early as 17 November 1965, Iain Macleod, the spokesman on economic issues for the United Kingdom's Conservative Party, warned of the gravity of the UK economic situation in the House of Commons: "We now have the worst of both worlds—not just inflation on the one side or stagnation on the other, but both of them together. We have a sort of "stagflation" situation. And history, in modern terms, is indeed being made."〔〔 〕 With these words, Macleod coined the term "stagflation". In a Bank of England working papers series, article authors Edward Nelson and Kalin Nikolov (2002) examined causes and policy errors related to the Great Inflation in the United Kingdom in the 1970s, arguing that as inflation rose in the 1960s and 1970s, UK policy makers failed to recognize the primary role of monetary policy in controlling inflation. Instead, they attempted to use non-monetary policies and devices to respond to the economic crisis. Policy makers also made "inaccurate estimates of the degree of excess demand in the economy, () contributed significantly to the outbreak of inflation in the United Kingdom in the 1960s and 1970s.〔 Stagflation was not limited to the United Kingdom, however. Economists have shown that stagflation was prevalent among seven major economies from 1973 to 1982. 〔United States, Japan, Germany, France, United Kingdom, Italy, Canada.〕 After inflation rates began to fall in 1982, economists' focus shifted from the causes of stagflation to the "determinants of productivity growth and the effects of real wages on the demand for labor".〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「stagflation」の詳細全文を読む スポンサード リンク
