Alan Greenspan, who led the United States Federal Reserve from 1987 to 2006, has died at the age of 100 due to complications from Parkinson's Disease.

1987年至2006年領導美國聯準會的 Alan Greenspan，因帕金森氏症併發症，於100歲時逝世。

Greenspan's professional journey began with music studies at the Juilliard School before he shifted to economics at New York University. His views were strongly influenced by the philosophy of Ayn Rand, which promoted free-market capitalism and the importance of individual interest. These beliefs guided his work as Chairman of the Federal Reserve, a position he held under four different U.S. presidents.

Greenspan 的職業生涯始於在茱莉亞學院學習音樂，隨後他轉到紐約大學學習經濟學。他的觀點深受 Ayn Rand 哲學的影響，該哲學推崇自由市場資本主義以及個人利益的重要性。這些信念指導了他擔任聯準會主席期間的工作，他在四位不同的美國總統任期內均擔任此職。

Under his leadership, the U.S. experienced significant economic growth and stable prices, especially between 1991 and 2001. Greenspan was known for using specific financial strategies to reduce market instability, a method often called the 'Greenspan put.' Furthermore, he tried to make the Federal Reserve more transparent by releasing public statements, although he often used a complex and vague style of speaking known as 'Fedspeak' to avoid giving too many clues to investors.

在他的領導下，美國經歷了顯著的經濟增長和物價穩定，特別是在1991年至2001年之間。Greenspan 以使用特定的金融策略來減少市場不穩定而聞名，這種方法通常被稱為「Greenspan put」。此外，他嘗試透過發布公開聲明使聯準會更加透明，儘管他經常使用一種被稱為「聯準會話 (Fedspeak)」的複雜且模糊的表達方式，以避免向投資者提供過多線索。

However, his reputation changed after the 2008 global financial crisis. Many critics argued that the crisis was caused by a long period of deregulation and an over-reliance on the ability of banks to regulate themselves. During a later testimony before Congress, Greenspan admitted there was a flaw in his theory, acknowledging that he was wrong to assume that financial companies would always act in their own best interest to protect their stability.

然而，在2008年全球金融危機後，他的名聲發生了變化。許多批評者認為，這次危機是由長期的去監管化以及過度依賴銀行自我監管能力所導致的。在隨後的一次國會聽證會上，Greenspan 承認其理論存在缺陷，承認他錯誤地假設金融公司會始終為了自身最大利益而維護其穩定性。

Alan Greenspan remains a key figure in American economic history, remembered both for the wealth created in the 1990s and the regulatory mistakes that led to the 2008 recession.

Alan Greenspan 依然是美國經濟史上的一個關鍵人物，人們對他的記憶既包括他在 1990 年代創造的財富，也包括導致 2008 年經濟衰退的監管錯誤。
