Resumo(s)
Research on intertemporal judgments and choices between a smaller-sooner and a larger-later
outcome has revealed many anomalies to the discounted-utility model. Attempts to account
for these anomalies within the discounting paradigm have resulted in convoluted and
psychologically opaque models. We therefore develop a new model of intertemporal choice,
the tradeoff model, in which choice results from a tradeoff between the perceived time
difference (interval) and the perceived outcome difference (compensation). This model is both
more parsimonious and more intuitive than any rival discounting model of comparable scope.
Moreover, it accurately describes archival data as well as data from a new experiment.
