This paper investigates the role of unconventional monetary policy as a source of time-variation in the relationship between sovereign bond yield spreads and their fundamental determinants. We use a two-step empirical approach. First, we apply a time-varying parameter panel modelling framework...

We offer a detailed empirical investigation of the European sovereign debt crisis based on the theoretical model by Arghyrou and Tsoukalas (2010). We find evidence of a marked shift in market pricing behaviour from a 'convergence-trade' model before August 2007 to one driven by...

We present a simple model explaining corruption on geography and climate conditions. We test the model's validity in a cross-section of 115 countries. Controlling for all other corruption's determinants we find evidence supporting the model's predictions. Corruption increases with temperature...

We use a macro-theory framework of analysis to assess Greek economic policy, with emphasis on the current period of the Greek debt crisis. We argue that this is mainly the result of misguided past internal policies deviating substantially from the policy lessons of modern macroeconomics. The...

Arghyrou, Gregoriou and Pourpourides (2009) argue that exchange rate uncertainty causes deviations from the law of one price. We test this hypothesis on aggregate data from the G7-area. We find that exchange rate uncertainty explains to a significant degree deviations from Purchasing Power...

The key ingredients of our proposal involve a temporary split of the euro into two currencies, both run...
