I investigate two versions of a differential Cournot oligopoly game with nonrenewable resource exploitation, in which each firm may either exploit its own private pool or exploit a common pool jointly with the rivals. Firms use a deterministic technology to invest in exploration activities. In...

This study uses the methods of experimental economics to investigate possible reasons for the lack of empirical support for the Hotelling rule for nonrenewable resources. We argue that as long as resource stocks are large enough, producers may choose to (partially) ignore the dynamic component...

We identify two possible equilibrium configurations for a non-renewable resource duopoly in a discrete-time framework. For the purpose of illustration, we suppose initial endowments of firms that allow for a maximum of two extraction periods. In the first possible equilibrium, the duopoly exists...

Policy reform debates in African economies often focus on poverty alleviation programs, liberalisation of trade and market and social service provisions. These reforms are heavily dependent on funding from either foreign sources or natural resource wealth, accompanied with concessions from the...

When environmental externalities are international - i.e. transfrontier - they most often are multilateral and embody public good characteristics. Improving upon inefficient laissez-faire equilibria requires voluntary cooperation for which the game-theoretic core concept provides optimal...

With regard to globalor regional environmental problems, do countries that take unilateral actions inspire other countries to curtail emissions? In this paper this possibility is investigated by the use of a novel design of a laboratory public bad experiment with a leader. Twelve groups of five...

Humanity's problem with climate change has been likened to a "tragedy of the commons". If the atmosphere is seen as an open access dump for gasses like CO2 or methane, Garret Hardin's conclusion from 1968: "Freedom in a commons brings ruin to all" is obviously correct. But how do we create a...

Social interactions provide a set of incentives for regulating individual behavior. Chief among these is stigma, the status loss and discrimination that results from the display of stigmatized attributes or behaviors. The stigmatization of behavior is the enforcement mechanism behind social...

We show that concealing cost information is a dominant strategy in heterogeneous Bertrand oligopolies. This result enables us to endogenize the number of firms in a market in terms of market size, entry costs, and unit cost uncertainty.

Unternehmen müssen nicht immer Kollusionsabsichten verfolgen, wenn sie untereinander Informationen austauschen. Dieser Beitrag zeigt, daß bei Nachfrageunsicherheit auch strikt kompetitive Konkurrenten private Informationen bezüglich ihrer Nachfragebedingungen preisgeben. Dies läßt sich in...
