- Title
"Spending Power" and the Subjective Discretionary Income (SDI) Scale.
- Authors
Rossiter, John R.
- Abstract
New measures of "spending power" from the economics literature are reviewed as alternatives to the total household income measure typically used in consumer research. The simplest of these, the Subjective Discretionary Income measure proposed by O'Guinn and Wells, is evaluated in a cross-national replication study with financial products. SDI appears to be a valid predictor of investments,"whereas total household income predicts "necessities." Lengthening of the SDI scale is suggested to increase its reliability.
