“…Nonetheless, measuring the size of the informal, or 'shadow', economy has been central to much of the research and publications of Friedrich Schneider, Professor of Economics at Johannes Kepler University, Linz, Austria. In a study assessing the size of the shadow economy over the period from 1999 to 2007 for a set of 162 states, the average for the period ranged from 66.1% (Bolivia) to 8.5% (Switzerland) [50].
