We investigate intertemporal strategic interactions if monopolies,cartels or oligopolies benefit from firm internal as well as external learning by doing. Our analysis is carried out for a linear learningcost curve because, it allows the derivation of the linear Markov perfectequilibrium (LMPE)....

Although the possibility of multiple nonlinear equilibria inlinear-quadratic differential games is extensively discussed, the literatureon models with multiple linear Markov perfect equilibria (LMPEs) isscarce. And indeed, almost all papers confined to a single state (a verylarge majority of the...

We investigate intertemporal strategic interactions if monopolies, cartels or oligopolies benefit from firm internal as well as external learning by doing. The analysis is carried out for learning cost curves based on the standard power and a linear function. The first allows for multiple long...

We consider how one party can induce another party to join an international emission compact given private information. Due to multilateral externalities the principal uses her own emissions besides subsidies to incentivize the agent. This leads to a number of non-standard features: Optimal...

China is a rising global power with a growing role and impact on the world's energy markets as well as on the Earth's climate system. China pursues its development in an essentially non-confrontational manner, a vision encapsulated by the notion of peaceful rise which is viewed positively in the...

Countries often have private information about their willingness to pay for protecting the climate system and their cost of emission reductions. We use a principal-agent model to re-examine the economic case for unilateral action by individual countries, in our case of the principal. We find...

This paper addresses the spatial evolution of countries accounting for economics, geography and (military) force. Economic activity is spatially distributed following the AK model with the output being split into consumption, investment, transport costs and military (for defense and expansion)....
