We demonstrate that the Varian (1980) model of sales has a unique Nash equilibrium when firms incur costly advertising to compete for informed consumers. The equilibrium is symmetric. In particular, with costly advertising, the asymmetric equilibria highlighted by Baye et al. (1992) do not arise.

We show that, in general, consistent estimates of cost pass-through are not obtained from reduced-form regressions of price on cost. We derive a formal approximation for the bias that arises even under standard orthogonality conditions. We provide guidance on the conditions under which bias may...
