We find that, unlike typical models, the sS bands in our model contract as the variance of the shock process increases. We also analyze a dynamic version of the model in which agents are allowed to make decisions that are conditional of the age of a used car. We find that, as a car ages, the lemons problem tends to decline in importance, and the sS bands contract. ER -
