The objective of the paper is to investigate the legitimacy of the African Union by examining the socio-demographic determinants of citizens' support of African integration. To do this, we use Rounds 4, 5, 6 and 8 of the Afrobarometer survey data corresponding to more than 110 000 respondents....

This paper provides empirical evidence on the short and long-term sectoral effect of environmental policy stringency on CO2 emissions, exploiting longitudinal data covering 30 OECD countries and more than 50 sectors. The analysis relies on the OECD Environmental Policy Stringency (EPS) index, a...

This paper identifies different types of climate change mitigation strategies countries adopted over the last two decades and assesses the policy synergies they might generate. The analysis exploits the rich policy repository of the OECD’s Climate Actions and Policies Measurement Framework...

The gender pay gap and the gender gap in employment remains persistent in Europe despite the basic assertion of gender equality under EU law. We assess the factors that influence the gender pay gap and gender employment gap across European countries. Therefore, we use an unbalanced panel of 31...

We study cluster-robust inference for binary response models. Inference based on the most commonly-used cluster-robust variance matrix estimator (CRVE) can be very unreliable. We study several alternatives. Conceptually the simplest of these, but also the most computationally demanding, involves...

For linear regression models with cross-section or panel data, it is natural to assume that the disturbances are clustered in two dimensions. However, the finite-sample properties of two-way cluster-robust tests and confidence intervals are often poor. We discuss several ways to improve...
