摘要：This paper studies a dynamic non-linear pricing problem, adding the possibility that the seller can costly renege on the initial contracts, which is common in reality in the forms of false advertising, add-on pricing and bait-and-switch. While reneging allows the seller to earn more surplus by offering a new full-extraction contract after learning the buyer' s preference, a forward looking buyer will hide information. We fully characterize the equilibrium direct mechanism with the presence of this strategic interaction and show that the quality distortion may be mitigated and participation can be higher when the market moves from full-commitment to one with modest reneging cost. In addition, we show that pooling mechanism can be also optimal since the seller can forgone learning opportunity in order to commit. We establish the precise condition under which the welfare improvement happens and further relate it to whether the market is niche or mass. Moreover, we show that in the sequential equilibrium, there always exists an implementable contract throughout the game even if the seller has already incurred the reneging cost and is free to modify it. By explicitly modeling seller's information extraction problem without full commitment, our results have policy implications on protecting consumers from deceptive business tactics.
