Using high quality administrative data on Greece we show that class size has a hump shaped effect on achievement. We do so both nonparametrically and parametrically, while controlling for potential endogeneity and allowing for quantile effects. We then embed our estimates for this relationship...

The Greek economy experienced a boom until 2007, followed by a prolonged depression resulting in a 25 percent shortfall of GDP by 2016. Informed by a detailed analysis of macroeconomic patterns in Greece, we estimate a rich dynamic general equilibrium model to assess quantitatively the sources...
