We derive several properties of commonly used discrete choice models that are potentially undesirable if these models are to be used as structural models of demand. Specifically, we show that as the number of goods in the market becomes large in these models, i) no product has a perfect substitute, ii) Bertrand-Nash markups do not converge to zero, iii) the fraction of utility derived from the observed product characteristics tends toward zero, iv) if an outside good is present, then the… CONTINUE READING
