Conventional wisdom has advanced competing theories: Wall Street types took too many risks, encouraged by lax government regulation; or pro-homeownership policies eroded mortgage-lending standards and created the housing bubble.<\/p>\n
Actually, both theories are correct \u201d\u201d and neither is….
[The real foundation was laid with Paul Volcker’s]… decisive defeat of double-digit inflation in the early 1980s.<\/p>\n
All the good news (low inflation, high employment, rising stock and real estate prices) drove economic growth. Between 1982 and 2007, there were only two mild recessions. When prosperity was jeopardized \u201d\u201d by the 1997 Asian financial crisis, the tech crash in 2000, the 9\/11 attacks \u201d\u201d the Federal Reserve seemed to defuse the threats. The economy seemed less risky. Economists announced the Great Moderation of business cycles.<\/p>\n
Booms become busts because justifiable confidence becomes foolish optimism. So it was. Believing the world less risky, people took more risks. Investment banks and households increased their debt. Lending standards eroded, because borrowers\u2019 repayment prospects were thought to have improved. Regulators relaxed oversight, because markets seemed more stable and self-correcting. On the fringes, ethical standards frayed; criminality increased. The rest, as they say, is history.<\/p>\n
