Economic Development & Growth

The Covid-19 pandemic has had a profound impact on the global economy, leaving us with a significant stock of additional debt. A widespread view is that the burden of servicing this debt should be distributed fairly, suggesting that tax systems should become more progressive. How should the optimal degree of income tax progression change if governments need to raise more revenues? In this article, the authors use the workhorse model of optimal income taxation to analyze the change in the degree of tax progressivity in response to the fiscal pressure caused by the Covid-19 pandemic.

What makes a good teacher? This is one of the central questions in the economics of education. General teacher qualifications, such as education level or advanced degrees, tend to be poor predictors of teacher quality. Instead, some studies have shown that subject-specific qualifications predict teacher quality better. However, the vast majority of such studies are based on data from the United States. It is therefore unclear to what extent the findings can be generalized to other nations, as teacher education programs vary widely across countries. The lack of international evidence is particularly problematic for developing economies, which would arguably benefit most from improving student achievement.

The new Policy Report analyses the role of social policies in different European welfare states regarding minimum income protection and active inclusion. It finds consistent differences in terms of crisis resilience across countries and welfare state types. In general, Nordic and Continental European welfare states with strong upstream systems and minimum income support (MIS) show better outcomes in core socio-economic outcomes such as poverty and exclusion risks. However, labour market integration shows some dualisms in Continental Europe. The study shows that MIS holds particular importance if there are gaps in upstream systems or cases of severe and lasting crises.
