David X. Li (born in China in the 1960s as Chinese: 李祥林; pinyin: Lǐ Xiánglín) is a quantitative analyst and a qualified actuary who in the early 2000s pioneered the use of Gaussian copula models for the pricing of collateralized debt obligations (CDOs). The Financial Times called him "the world’s most influential actuary," while in the aftermath of the Global financial crisis of 2008–2009, to which Li's model has been credited partly to blame, his model has been called a "recipe for disaster".

Famous quotes containing the word david:
“All men are partially buried in the grave of custom, and of some we see only the crown of the head above ground. Better are the physically dead, for they more lively rot. Even virtue is no longer such if it be stagnant. A man’s life should be constantly as fresh as this river. It should be the same channel, but a new water every instant.”
—Henry David Thoreau (1817–1862)
