The paper develops a theoretical framework for studying conspicuous consumption. This is modeled as a device that signals the consumer's social status. Status is some function of the individual's rank in the wealth hierarchy. This approach makes it possible to distinguish between snob and...

Food labelling has become a major element of food policy. The growing importance of the topic is associated with a large variety of labels which refer to very different characteristics of foods and are linked to a growing number of quality assurance schemes. The economics of labelling is still...

It is well known that in a differential information economy the free coalition formation may imply some theoretical difficulties. It does not suffice to say that a coalition can be formed by several agents. We define a set of all possible coalitions as the set of those coalitions that can be...

Ken Arrow (1998) asks, “What has economics to say about racial discrimination?” He replies – entirely correctly – that racial “segregation within an industry – that is, firms with either all black or all white labor forces” – may be explained by economic theory, but “the...

Pay-What-You-Want (PWYW) pricing schemes are becoming increasingly popular in a wide range of industries. We develop a model incorporating self-image into the buyer's utility function and introduce heterogeneity in consumption utility and image-sensitivity, which generates different purchase...

Many disasters are foreshadowed by insuficient preventive care. In this paper, we argue that there is a true problem of prevention, in that insu¢ cient care is often the result of rational calculations on the part of agents. We identify two factors that lead to dubious e¤orts in care. First,...

TThe formation of coalition may imply some theoretical difficulties, such as costs arising from forming a coalition or sharing information among agents. In this paper we will assume that only a subset S of the set of all possible coalitions in an economy is the set of admissible coalitions. We...

We present a model in which an agent takes actions to affect her reputation with two audiences with diverse preferences. This contrasts with standard reputation models that consider a homogeneous audience. A new aspect that arises is that different audiences may observe outcomes commonly or...
