This paper considers the diverse public good characteristics of COVID-19 activities along with their strategic implications. The underlying aggregator technologies, which relate individual contributions to the amount consumed, affect the prognosis for the supply of COVID-related activities....

In debates over privatization and global competition mixed Cournot oligopoly models have been used to show that the presence of a state-owned enterprise in the host country is always associated with a distortionary effect that may justify privatization even if the public firm is just as...

This study investigates the possible sources of distortions in an international mixed oligopoly. We extend the existing linear/quadratic model to a general framework and show that a public enterprise may either serve as a regulatory device or may itself create an additional level of distortion....

Recent international climate negotiations suggest that complete agreements are unlikely to materialize. Instead, partial cooperation between like-minded countries appears a more likely outcome. In this paper we analyze the effects of such partial cooperation between like-minded countries. In...

We extend the standard public good provision model to allow players to either like or dislike the public characteristic. Those who dislike it are able to take actions to reduce its level. We present conditions under which the existence of a unique noncooperative equilibrium is retained, and...

Free riding is explained in a model of voluntary production of public goods, in terms of the heterogeneity of households. To achieve this the traditional essentially Ricardian model of voluntary production of pure public goods is generalised to comprise any number of private and public goods,...

When providing public goods through voluntary contributions, a donor may introduce unilateral matching in order to reduce underprovision of the public good and thus inefficiency. By itself, however, matching benefits the donor but harms the recipient. We apply Cornes and Hartley's aggregative...

We present a rigorous, yet elementary, demonstration of the existence of a unique Lindahl equilibrium under the assumptions that characterize the standard n-player public good model. Indeed, our approach, which exploits the aggregative structure of the public good model, lends itself to a...

In a public good economy the distribution of initial income is an important determinant of how many individuals contribute to the public good. For the case when all individuals have identical preferences in this paper a simple formula is derived that describes the proportion of all income...

A rapidly growing literature analyzes models in which firms maximize objectives other than profit and enjoy market power. Examples include the labor-managed firm, mixed oligopoly, and delegation models. These models typically retain the aggregative structure of the conventional Cournot model of...
