The model identifies the quality of a network product with the number of consumers using it. Hence, the producer cannot unilaterally control the quality of his product. Using the preference specification of vertical quality differentiation, it is shown that the largest network produced will be...

This paper recommends a system of rewards for public officials which is linearly related to the performance of the official. The main advantage of such a system of compensation is that it serves as a regular ‘self checking’ of the performance of an official and it reduces the need for a...

Shitovitz and Spiegel (1998) demonstrated that in pure public good economies, for some consumers the Lindahl consumption bundles can be inferior (utility-wise) to their Cournot-Nash allocation. In this paper, we prove that in any finite pure public good economy there exists a core allocation...

This paper analyzes the voluntary provision of the pure public good in a sequence of finite economies. The boundedness of this provision is established under very weak conditions. The Cournot-Nash provision of the public good is bounded. In contrast, the Lindahl provision is unbounded but the...

In this paper, charity is considered as a strategic selfish activity that increases the welfare of the contributors without altruism. The model supposes the interactive simultaneous utility maximization of two consumer groups, contributors and recipients, who share the same utility function but...
