After more than 20 years of European Monetary Union (EMU), surprisingly few scientific studies exist which study the growth effects of introducing a common currency in large parts of the European Union. I do so using a large panel (NUTS3 data) of regional data for the EU-15. Some 800 (treated)...

The purpose of this paper is twofold: 1) to highlight the widely ignored but fundamental problem of ‘superpopulations’ for the use of inferential statistics in development studies. We do not to dwell on this problem however as it has been sufficiently discussed in older papers by...

The growing availability of Geo-referenced information needs particular econometric tools such as those developed by Spatial Econometrics. This econometric branch is dedicated to the analysis of heterogeneity and spatial dependence in regression models. In this paper, I review the most...

We analyze the conditions in which ignoring spatial correlation is problematic for inference in differences-in-differences (DID) models. Assuming that the spatial correlation structure follows a linear factor model, we show that inference ignoring such correlation remains reliable when either...

The synthetic control (SC) method has been recently proposed as an alternative to estimate treatment effects in comparative case studies. The SC relies on the assumption that there is a weighted average of the control units that reconstructs the potential outcome of the treated unit in the...

The synthetic control (SC) method has been recently proposed as an alternative to estimate treatment effects in comparative case studies. In this paper, we revisit the SC method in a linear factor model setting and consider the asymptotic properties of the SC estimator when the number of...

The synthetic control (SC) method has been recently proposed as an alternative to estimate treatment effects in comparative case studies. An important feature of the SC method is the inferential procedures based on placebo studies, suggested in Abadie et al. (2010). In this paper, we evaluate...

This paper derives some exact power properties of tests for spatial autocorrelation in the context of a linear regression model. In particular, we characterize the circumstances in which the power vanishes as the autocorrelation increases, thus extending the work of Krämer (2005, Journal of...
