We study the effects on the food market of the introduction of biofuels as a substitute for fossil fuel in the energy market. We consider a world economy with an oil cartel and a competitive fringe of farmers producing energy in the form of biofuels. Farmers also produce food and sell it on the...

The present work characterizes the unique Nash equilibrium for games that are based on a cyclic preference relation. In the Nash equilibrium of these games, each player randomizes between three specific actions. In particular, an alternative way of deriving the unique Nash equilibrium of the...

We study the effects on the food price of introducing biofuels as a substitute for fossil fuel in the energy market. Energy is supplied by a price-leading oil cartel and a competitive fringe of farmers producing biofuel. Biofuel production shares a finite land resource with food production. A...

This paper studies the stockpiling issue for an oil importing country that is likely to suffer embargoes, the occurrence and duration of which are uncertain. I show the existence of a decreasing reserves path that the country wants to attain in order to hedge against these disruptions. Allowing...

The present paper proposes a dynamic framework for the analysis of emissions abatement by different countries. Unlike many related works, it emphasizes the non-cooperative aspects of this issue. We derive the feedback Nash equilibrium as well as the cooperative emissions paths. Under the...

For the class of shortest path games, we propose a family of new cost sharing rules satisfying core selection. These rules allocate shares according to some lexicographic preference relation. A computational procedure is provided. Our results relate to those of Tijs et al. (2011).
