Junk Bonds
Prior to the 1980s, fixed-income investors such as pension funds and insurance com-
panies were generally unwilling to buy risky bonds, so it was almost impossible for
risky companies to raise capital in the public bond markets. Then, in the late 1970s,
Michael Milken of the investment banking firm Drexel Burnham Lambert, relying on
historical studies that showed that risky bonds yielded more than enough to compen-
sate for their risk, began to convince institutional investors of the merits of purchasing
risky debt. Thus was born the “junk bond,” a high-risk, high-yield bond issued to fi-
nance a leveraged buyout, a merger, or a troubled company.^18 For example, Public
