In fall 2008, the stock market suffered a severe decline. Fear prompted a number of individuals to suspend contributions to their 401(k) retirement accounts. They reasoned that holding the money and having it retain its face value was preferable to putting it in a money-losing investment. Even employees who were invested in bonds, rather than equities, stopped contributing. Hiding money in a mattress was common following the 1929 stock market crash. In today's world, a worker simply stops contributing to his 401(k).
