In this paper, we propose the concepts of substitutability and complementarity in discrete choice models. These … study conditions on discrete choice models that will lead to substitutability and complementarity. Particularly, we show … model and the welfare-based choice model allow more flexible substitutability/complementarity patterns. We also present ways …
