Abstract: | We analyse preferences over finite decision problems in order to model decision-makers with „changing tastes”. We provide conditions on these preferences that identify the Strotz model of consistent planning. Building on an example given by Peleg and Yaari (1973) , we show that for problems with infinitely many choices, Strotz's representation of preferences may not be well defined. For that case, we propose a well-defined approximation which is empirically indistinguishable from the Strotz preference that is being approximated. |
