We present a signaling model, based on ideas of Phillip Nelson, in which both the introductory price and the level of directly "uninformative" advertising or other dissipative marketing expenditures are choice variables and may be used as signals for the initially unobservable quality of a newly introduced experience good. Repeat purchases play a crucial role in our model. A second focus of the paper is on illustrating an approach to refining the set of equilibria in signalling games with… 
Dissipative Advertising Signals Quality even without Repeat Purchases
Economists have emphasized the role of dissipative advertising and price as signals of quality. Most works, however, limit the number of types to two options: high and low quality. Yet, production

A Model of Advertising and Product Quality
This essay presents a model of a single market in which goods of different qualities are sold and sellers advertise. Sellers advertise noncooperatively, knowing rivals' outlays and buyers' behavior
Advertising as a Signal
A great deal of advertising appears to convey no direct credible information about product qualities. Nevertheless, such advertising may indirectly signal quality if there exist market mechanisms
Managerial Incentives, Investment and Aggregate Implications: Scale Effects
We explore a managerial model of investment behaviour in which an incentive problem arises because one input factor (managerial effort) is not publicly observed. We show that an optimal incentive
Premiums for High Quality Products as Returns to Reputations
This paper derives an equilibrium price-quality schedule for markets in which buyers cannot observe product quality prior to purchase. In such markets there is an incentive for sellers to reduce
Signaling Games and Stable Equilibria
Games in which one party conveys private information to a second through messages typically admit large numbers of sequential equilibria, as the second party may entertain a wealth of beliefs in

The Role of Market Forces in Assuring Contractual Performance
The conditions under which transactors can use the market (repeat-purchase) mechanism of contract enforcement are examined. Increased price is shown to be a means of assuring contractual performance.
