Interests and experience

In general the thesis focus theoretically on the problem of decommissioning of guerrilla groups before, during and after a peace treaty has been signed. Different aspects of this problem are illustrated by using game theory. More specifically do I consider the case of Northern Ireland, and the problem with decommissioning of the Irish Republican Army. The analysis is three-folded:

  • How do the use of threats influence the outcome of a negotiation process? An analysis of the situation between Great Britain, the UUP and Sinn Fein/the IRA before the all-party talks started.

  • How is it possible make an agreement self-enforcing, and furthermore how is it possible to verify that the actors keep their end of the bargain? An analysis of the Good Friday Agreement.

  • The problems of assuming unitary actors in game theory. A thorough analysis of the distinction between Sinn Fein and the IRA, and the problems the IRA faces concerning internal hard-liners.
