This paper analyzes optimal product lines when consumers differ both in their taste for quality and in their desire for social image. The market outcome features partial pooling and product differentiation that is not driven by heterogeneous valuations for quality but by image concerns. A...

We investigate how an informed designer maximizes her objective when facinga player whose payoff depends on both the designer's private information andon an unknown state within the classical quasilinear environment. Thedesigner can disclose arbitrary information about the state via...

This paper provides a noncooperative approach to core stability in an economy with incomplete information. The analysis covers general exchange economies, although our tightest results hold when effective coalitions consist of at most two players, as in matching. We study the perfect Bayesian...

The literature on charitable giving suggests that individuals may use their charitable donations to signal their altruism or their income. We argue that, rather than signaling income per se, individuals may want to signal other unobservable characteristics that correlate to income, such as their...

When grades lose their informative value because the percentage of students receiving the best grade rises without any corresponding increase in ability, this is called grade inflation. Conventional wisdom says that such grade inflation is unavoidable since it is essentially costless to award...

Two firms produce a product with a horizontal and a vertical characteristic. We call the vertical characteristic quality. The difference in the quality levels determines how the firms share the market. Firms know the quality levels, consumers do not. Under non-comparative advertising a firm may...

Open source projects produce goods or standards that do not allow for the appropriation of private returns by those who contribute to their production. In this paper we analyze why programmers will nevertheless invest their time and effort to code open source software. We argue that the...

Insurance intermediation services are information services which exhibit strong information asymmetries. We empirically analyze whether signaling works in the German market for insurance intermediation services. For this a signal must increase service quality and be easily identifiable by...

In a recent paper, Jäger, Metzger, and Riedel (2011) study communication games of common interest when signals are simple and types complex. They characterize strict Nash equilibria as so-called Voronoi languages that consist of Voronoi tesselations of the type set and Bayesian estimators on...
