In this episode, Eric and Nick talk to Michael Keen, a former Deputy Director of the IMF's Fiscal Affairs Department and co-author of "Rebellion, Rascals and Revenue", about the many ways taxation can go wrong throughout history.

They explore bizarre historical taxes like Britain's window tax and ship taxation, discuss New Zealand's exemplary GST system, and examine how poor tax design can lead to smuggling, rebellions, and unintended economic distortions.
