Corruption has been around for a very long time and will be around in the future unless governments can figure out effective ways to combat it. This is not going to be easy. Although the study of the causes and consequences of corruption has a long history in economics, going back 30 years to seminal contributions on what economists call rent seeking, related empirical work on quantifying the extent of corruption and putting a dollar sign on its economic effects has been limited. This is hardly surprising since most corruption is clandestine. Also, determining just how efficient government institutions are is not what would be called an exact science. As a consequence, corruption is notoriously hard to measure and empirical economic research on the question is fairly meagre. The prevailing view is that corruption is harmful to economic growth. This new book presents the latest research from around the globe.
