In the early 1990s the World Bank launched the Regional Program on Enterprise Development (RPED) in several African countries, a keycomponent of which was to collect data on manufacturing firms. The data sets built by these and subsequent enterprise surveys in Africa generated considerable...

We investigate any similarity and dependence based on the full distributions of cryptocurrency assets, stock indices and industry groups. We characterize full distributions with entropies to account for higher moments and non-Gaussianity of returns. Divergence and distance between distributions...
