'Paying Bribes for Public Services' by Professor Richard Rose
Professor Richard Rose (DPhil: Politics, 1957) has, with Caryn Peiffer, written Paying Bribes for Public Services: A Global Guide to Grass-Roots Corruption.
This book documents what happens when people encounter public officials. It draws on multi-national Barometer surveys asking questions about corruption and bribery in 119 countries. Clear prose, tables and figures report the answers given by more than 250,000 people and the conclusion sets out six principles for reducing bribery.
