First, though, some definitions. Generally speaking, wealth is the value of everything a person or family owns, minus any debts. However, for purposes of studying the wealth distribution, economists define wealth in terms of marketable assets, such as real estate, stocks, and bonds, leaving aside consumer durables like cars and household items because they are not as readily converted into cash and are more valuable to their owners for use purposes than they are for resale (see Wolff, 2004, p. 4, for a full discussion of these issues). Once the value of all marketable assets is determined, then all debts, such as home mortgages and credit card debts, are subtracted, which yields a person's net worth. In addition, economists use the concept of financial wealth -- also referred to in this document as "non-home wealth" -- which is defined as net worth minus net equity in owner-occupied housing. As Wolff (2004, p. 5) explains, "Financial wealth is a more 'liquid' concept than marketable wealth, since one's home is difficult to convert into cash in the short term. It thus reflects the resources that may be immediately available for consumption or various forms of investments."
