Zahariadis offers a theory that explains policymaking when "ambiguity" is present - a state in which there are many ways, often irreconcilable, of thinking about an issue.

The cases cover economic policymaking in Britain, France, and Germany, foreign policymaking in Greece, all compared to the US (where the model was first developed), and an innovative computer simulation of the policy process.
