Standard econometric models of discrete choice (such as Fechner model of random errors, Luce’s choice model and random utility or random preference approach) are not well suited for applications to intertemporal choice. This paper proposes a new model that does not violate temporal dominance,...

A new model of intertemporal choice — "discounted incremental utility" (DIU) — is presented. DIU coincides with Samuelson's discounted utility (constant/exponential discounting) when utility function is linear. DIU has several advantages over discounted utility (and its generalizations —...

Intertemporal choice is intuitively analogous to choice under risk/uncertainty when outcomes are viewed as consequences received in an uncertain future. "Discounted incremental utility" (DIU) model of intertemporal choice parallels expected utility representation of risk preferences. DIU...

Discounted utility theory and its generalizations (e.g., quasihyperbolic discounting, generalized hyperbolic discounting) use discount functions for weighting utilities of outcomes received in different time periods. We propose a new simple test of convexity-concavity of discount function. This...
