Following the sovereign debt crisis of 2012, some southern European countries have debated proposals to leave the Euro. We evaluate this policy change in a standard monetary model with seigniorage financing of the deficit. The main novel feature is that we depart from rational expectations while...

Consumption-based asset pricing models with time-separable preferences can generate realistic amounts of stock price volatility if one allows for small deviations from rational expectations. We consider rational investors who entertain subjective prior beliefs about price behavior that are not...
