Greece’s Three-Act Tragedy: A Simple Model of Grexit vs. Staying Afloat inside the Single Currency Area

Against the backdrop of the Greek three-act tragedy, we present a theoretical
framework for studying Greece’s recent debt and currency crisis. The model is built on two essential blocks: first, erratic macroeconomic policymaking in Greece is described using a stochastic regime-switching model; second, the euro area governments’ responses to uncertain macroeconomic policies in Greece are considered. The model’s mechanism and assumptions allow either for a Grexit from the euro area or, conversely, the avoidance of Greece’s default against its creditors. The model also offers useful guidance to understand key drivers of the long-winded negotiations between the Greek government and the “institutions”.
