About Colin C Williams

My personal research interests are on evaluating the extent and nature of the underground economy (or what is often termed the informal, cash-in-hand, hidden, shadow or undeclared economy) and examining policy approaches for tackling this sphere. Recent clients include the European Commission, European Foundation for the Improvement of Living and Working Conditions and numerous departments of national governments. I am currently Lead Expert to the European Commission's European Platform Tackling Undeclared Work.
