Four studies demonstrated robust withinand between-subject differences in willingness-to-pay (WTP) and willingness-to-accept (WTA) measures of the value of lottery tickets. Buyers and sellers attended to different numerical cues and interpreted the same numbers differently when setting these two kinds of monetary values. Affective infiuences appeared to guide the valuation process. Buyers with ...
