We investigate the controversial role of the informal sector in the economy of 64 countries between 2003 and 2007 by focusing for the first time on the impact it has on sovereign debt markets. In addition to a standard ordered Probit regression, we employ two nonparametric neural network...

We investigate the impact of local and global macroeconomic factors on Eurobonds and local currency issued bonds in Sub-Saharan Africa, at different points on the yield curve. Using a unique proprietary data set collected from local authorities, central banks and independent international...
