2018
Abstract Convergence analysis is typically envisaged either from a macro or a micro perspective. However, empirical tests tend to ignore that the two levels are often “nested” in a hierarchy. Building on hierarchical growth curve modelling, we propose an approach to convergence analysis that allows contemporaneous inference on macro and micro-convergence. Compared to the classic linear convergence analysis, the suggested methodology provides a more flexible alternative to model heterogeneity and validate the results for possible Galton's fallacy. We illustrate the approach in two empirical examples, one considering convergence across European regions and countries and the other across Itali…

INTRODUCTIONSpring, 1941. The German campaigns in the Balkans are strengthening the Nazi domination of continental Europe. The Lend-Lease bill signed by Roosevelt on 1 1 March has broken any neutrality pretence of the USA.

The war is about to become global and US and British leaders discuss strategy in the event that the USA finally enters actively into the war. In this context, the British physicist Charles Galton Darwin (1887-1962) is appointed Director of the British Central Scientific Office in Washington - an institution conceived to promote closer contact and exchange of inform…
