Who does, and who should initiate costly certification by a third party under asymmetric quality information, the buyer or the seller? Our answer - the seller - follows from a nontrivial analysis revealing a clear intuition. Buyer-induced certification acts as an inspection device,...

In the market where inattentive buyers can fail to notice some feasible choices, the key role of marketing is to make buyers aware of products. However, the effective marketing strategy is often subtle since marketing tactics can make buyers cautious. This paper provides a framework to analyze...

Consider a two-product firm that decides on the quality of each product. Product quality is unknown to consumers. If the firm sells both products under the same brand name, consumers adjust their beliefs about quality subject to the performance of both products. We show that if the probability...

Decisions to donate time or money for charitable purposes are typically seen as make-or-buy decisions, implying that there should be a clear distinction between individuals engaging in one of these two forms of giving and that this distinction should be somehow linked to opportunity costs. But...

We analyze optimal redistribution in the presence of labor market signaling where innate productive ability is not only unobserved by the government, but also by prospective employers. Signaling in both one and two dimensions is considered, where in the latter case firms have an informational...

We study a symmetric private value auction with signaling, in which the auction outcome is used by an outside observer to infer the bidders’ types. We elicit conditions under which an essentially unique D1 equilibrium bidding function exists in the second-price auction and the English auction....

We study the optimal entry fee in a symmetric private value first-price auction with signaling, in which the participation decisions and the auction outcome are used by an outside observer to infer the bidders’ types. We show that this auction has a unique fully separating equilibrium bidding...

We develop a model of manager-employee relationships where employees care more for their manager when they are more convinced that their manager cares for them. Managers can signal their altruistic feelings towards their employees in two ways: by offering a generous wage and by giving attention....

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 costs and quality both result from R&D efforts and therefore are both uncertain. I characterize the...
