The advantages and disadvantages of genetic modification of organisms in agriculture are reviewed. These relate to the environment, human health, socio-economic effects, population growth, and differential consequences for developed and developing countries. An overall evaluation requires that...

In this paper we argue that authorities aid cooperation by means of direct coordination or the enforcement of re-commitment devices such as contract laws.Credible threats of violence allow this role. In a local interaction model, an authority forms if mutually connected individuals with...

In a standard general equilibrium model it is assumed that there are no price restictions and that prices adjust … infinitely fast to their equilibrium values. In this paper the set of admissible prices is allowed to be an arbitrary convex set …. For such an arbitrary set it cannot be guaranteed that there exists a constrained equilibrium satisfying the usual …

interrelationship between firm entry and exit in disequilibrium. Introducing a new methodology we investigate whether this … interrelationship differs between market ‘undershooting’ (the actual number of firms is below the equilibrium number) and ‘overshooting …’ (vice versa). We find that equilibrium-restoring mechanisms are faster in over than in undershoots. The results imply that …

Any function from a non-empty polytope into itself that is locally gross direction preserving is shown to have the fixed point property. Brouwer's fixed point theorem for continuous functions is a special case. We discuss the application of the result in the area of non-cooperative game theory.
