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...

Recent research has focused on what shapes gender differences in academic achievement and students' choice of university field of study. In this paper we examine how teachers' gender role attitudes and stereotypes influence the gender gap by affecting the school environment. We explore the...

The Greek crisis was the most severe in postwar Europe; its budget cuts were the deepest. Among the components of the budget, health spending was hit particularly hard, declining by more than one third in just five years. This paper has two goals: establish the facts about health inputs, outputs...

We use a new dataset consisting of the universe of Greek corporate tax returns matched to financial statements to study a voluntary tax compliance program for small firms. This "self-assessment" program prescribed target taxable profit margins for different types of activity. Firms that reported...

We estimate the impact of the COVID-19 crisis on business failures among small and medium size enterprises (SMEs) in seventeen countries using a large representative firm-level database. We use a simple model of firm cost-minimization and measure each firm's liquidity shortfall during and after...

Human capital can depreciate if skills are unused. But estimating human capital depreciation is challenging, as worker skills are difficult to measure and less productive workers are more likely to spend time in non-employment. We overcome these challenges with new administrative data on...

This paper assesses the prospects of a 2021 time bomb in SME failures triggered by the generous support policies enacted during the 2020 COVID-19 crisis. Policies implemented in 2020, on their own, do not create a 2021 "time-bomb" for SMEs. Rather, business failures and policy costs remain...

This paper analyzes the response of earnings to payroll tax rates using a cohort-based reform in Greece. All individuals who started working on or after 1993 face permanently a much higher earnings cap for payroll taxes, creating a large and permanent discontinuity in marginal payroll tax rates...

We document that in semiformal economies, banks lend to tax-evading individuals based on the bank's assessment of the individual's true income. This observation leads to a novel approach to estimate tax evasion. We use microdata on household credit from a Greek bank, and replicate the bank...
