Hyperbolic discounting (H) is currently the dominant behavioral model of intertemporal choice, since it better explains how people behave than the normatively correct exponential discounting model (E). This paper promotes an arithmetic discounting model (A) which challenges H. First, A is more...

We examine the confounding between models of intertemporal choice. Critical outputs from hyperbolic, exponential and arithmetic discounting are all highly multicolinear in commonly used research designs. This confounding means that if one model defines a participant as impulsive, they all will:...

The paper surveys over twenty models of delay discounting (also known as temporal discounting, time preference, time discounting), that psychologists and economists have put forward to explain the way people actually trade off time and money. Using little more than the basic algebra of powers...

This paper has four objectives. First, we describe and evaluate three models of delay discounting (time preference), showing how they relate to each other and to already established concepts in accounting/finance and elsewhere. The models are: exponential (E), hyperbolic (H), and arithmetic (A),...
